letter to the editor
Huge opportunity beckons
As a young chemical engineer, I was very excited about the conversion of reactants under the appropriate environment—perhaps
with the use of a catalyst—into useful products. Such reactions are usually written A + B ➞ C. As an older, and hopefully wiser,
materials scientist/engineer, I tend to look at how this simple equation might be applied to more global issues.
A case in point is energy generation and use in the United States. In a recent issue of American Ceramic Society Bulletin (Vol. 93,
No. 5, p. 5), the “News & Trends” section featured a Lawrence Livermore National Laboratory flowchart. It shows all sources of
energy production and their end use in 2013. I had seen similar charts before. However, in this case, one figure impressed me:
Of the approximately 97.4 Quads of energy produced, 59.0 Quads—more than 60%—were rejected, mostly as waste heat! The
electricity generation and transportation sectors had exceedingly large fractions of rejected energy, each more than 60%.
The same issue of the Bulletin featured articles about thermionics and other devices that could transform waste heat into electricity. Thus, I would like to suggest a simple new equation: rejected energy + conversion devices ➞ energy savings. Converting just
1%–10% of rejected energy into electricity would generate 0.6 to 5.9 Quads—a significant amount of energy.
This concept creates a huge challenge for the ceramic community, which includes universities, manufacturers, and the government. We need to move forward with prototype devices that can be tested in the field for electricity generation and transportation sectors noted above. We should not wait for low-cost or more efficient devices to come along. They will in time. As John
Deutch of MIT strongly pointed out, the enemy of good is best. The time is ripe for a major commitment. Are we, as a ceramic
community, up for the challenge?

news & trends
During a trip to China late last
year, President Barack Obama met
with Chinese President Xi Jinping to
discuss numerous issues, including
climate change.
China, the world’s top carbon dioxide
emitter, relies heavily on fossil fuels and
produces almost a third of all global carbon emissions, or 7.2 tons per person.
For comparison, the entire European
Union accounts for about 10% and the
United States for 16%.
But there are signs that China is making steps toward a more permanent pollution solution.
The two leaders emerged from their
November talks to announce that both
countries were committing to reaching
“ambitious” climate pollution targets—
with the U.S. set to reduce greenhouse
gas emissions to 26%–28% less than
2005 levels by 2025 and China pledging to increase its use of zero-emission
sources to 20% by 2030. China also
agreed—for the first time—to limit its
carbon dioxide emissions before 2030 as

of economics and air pollution, a call Xi
has referred to as an “energy revolution.”
Obama declared the climate change

Social Sciences shows that although
China may be serious about its efforts
to mitigate climate change, it demands
more energy than ever before.
According to Jari Kaivo-oja, research
director of the Finland Futures Research
Centre, “From a global perspective, we’re
seeing that China is channeling investments into renewable energy. While the
growth in renewable energy capacity has
been fast, the demand for energy has
grown even faster, forcing China to further increase its coal power capacity.”
China’s growing economy, in part,
means more coal, and more coal means
more emissions. Improvements in manufacturing and policy will not be enough,
Kaivo-oja says, to curb the increased
demand resulting from a continued shift
in consumer preferences and “rapid rise in
affluence”—or to meet those 2030 targets.
“Our research shows that the ongoing structural change visible in the
Chinese economy will curb the growth
in carbon emissions by only 25% in
comparison to the current economy,
which is largely dependent on heavy
industry,” he says. “At present, the

RETSCH - New High
Energy Ball Mill Emax
The Emax is an entirely new type
of ball mill for high energy milling. The unique combination of
high friction and impact results in
extremely fine particles within the
shortest amount of time. The high
energy input is a result of an unrivaled speed of 2000 min-1 and
the optimized jar design. Thanks
to the revolutionary cooling system
with water, the high energy input
is effectively used for the grinding
process without overheating the
sample. Due to the special grinding jar geometry, the sample is thoroughly mixed which results in a narrow particle size distribution.

CARBOLITE - New
Compact Modular Tube
Furnaces
The new 1200 °C E-series of
tube furnaces from CARBOLITE offer an extensive range
of compact split and non-split
tube furnaces for laboratory
use. The furnaces are available
with heated lengths of 150, 300,
450 and 600 mm and a maximum
tube diameter of 60 mm.
The split tube furnaces are hinged,
allowing them to be opened to
reduce the cool-down time. In
combination with the fast heat up
rates, this results in a high sample throughput. The three-zone models
ensures a longer uniform zone compared with a single zone furnace. An
easy to use angle adjustment option on the vertical furnaces also allows
horizontal and multi-angle configurations.

plans for the development of the country’s energy system won’t help China
cap its emissions by 2030.”
Whether or not China can meet its
emission reduction goals, the country
will have plenty of opportunities to at
least attempt to reach the admittedly
aggressive targets.
“China is a country still in the midst
of a wave of urbanization,” says Kaivooja. “The infrastructure solutions in new
urban areas and the consumer habits of
a developing and increasingly well-to-do
middle class are two issues that can significantly influence future developments.
China has made huge investments in sustainable cities and in sustainable development exercises, which are all very positive
signals from the viewpoint of sustainable
energy and climate policy.” n
Glass cockpit aboard NASA’s
Orion spacecraft sets course for
future space travel
NASA’s Orion spacecraft recently
completed its first unmanned space journey. Although the trip lasted only four
and a half hours while completing two
earth orbits, it was an important mile-
stone for eventually delivering humans
far into deep space—whether to an asteroid, Mars, or elsewhere.
Regardless of where it will go, NASA
decked out Orion with the latest technology. The spacecraft resembles the
iconic cone-shaped Apollo craft, but carries new and improved technology.
Orion, when ready for its human passengers, will be equipped with a glass
cockpit control system, according to
NASA. The system consists of panels of
screens for controlling the craft, rather
than the former extensive array of knobs,
buttons, and levers.
Efforts like the Materials
Genome Initiative and Advanced
Manufacturing Technology Consortia
program have been part of the plan to
get advanced materials and technologies from lab to market more quickly.
Now, advanced manufacturing and
advanced composites stand to be lighter,
faster, and stronger more quickly, thanks
to an infusion of cash and commitments
from government and investors.
The White House recently
announced a new $259-million public–private partnership in the creation of the Department of Energy’s
Institute for Advanced Composites
Manufacturing Innovation (IACMI),
which will be led by and headquartered at the University of Tennessee.
According to a DOE press release,
IACMI “will focus on making
advanced composites less expensive
and less energy-intensive to manufacture, while also making the composites
easier to recycle.”
The institute represents commitments from its partners ($189 million) and the DOE ($70 million),
which together form a consortium of
122 manufacturers, universities, and
national labs.
“This has brought together unprec-

edented commitment from state
governments, industries, and research
institutions to develop the workforce,
create jobs, and increase global manufacturing competitiveness in advanced
polymer composites,” IACMI CEO
Craig Blue says in a UT news release.
One of those manufacturers is
Local Motors, who—together with Oak
Ridge National Laboratory, Cincinnati
Incorporated, and the Association for
Manufacturing Technology—built the
world’s first 3-D printed car.
Using the same Big Area Additive
Manufacturing machine that helped
print Local Motors’ Strati, a six-person
ORNL team has taken its own 3-D
printed offering—a “‘plug-n-play’ laboratory on wheels” that pays homage to
the classic Shelby Cobra design—from
concept to car in just six weeks. The
ORNL car, made of 20% carbonfiber material, will “allow research
and development of integrated components to be tested and enhanced
in real time, improving the use of
sustainable, digital manufacturing
solutions in the automotive industry,”
according to ORNL.
It also demonstrates, says the
DOE, the type of collaborative work
that will accelerate the process from
concept to prototype and boost
American manufacturing. n

Some manual controls will be present,
but the glass cockpit design eliminates
the vast majority. The glass cockpit
reduces weight by removing wires and
switches and provides flexibility to the
cockpit and control panel.
On reentry to earth, the craft will
hurtle back through the atmosphere at
24,545 mph. Orion’s elaborate thermal protection system, fabricated by
Lockheed Martin, protects it from
blistering temperatures that may reach
up to 6,000°F. The entire base of the
craft is covered in a composite heat
shield wrapped in an ablative material
called Avcoat—deposited in 320,000
cells in a fiberglass-phenolic honeycomb
skin—that is designed to burn off to prevent heat build-up.
In addition, the craft’s backshell is
covered in 970 high-tech black AETB-8
tiles. “Made of a low-density, high-purity
silica fiber made rigid by ceramic bonding, the tiles will be called upon to
protect the sides of Orion from temperatures up to 3,150°F (1,732°C) on this
test,” NASA says.
Although the recent test flight did not
reach speeds and temperatures as high
as the craft will experience during a longer mission, the test was an important
step in evaluating the system. Lockheed
Martin engineers are currently sampling
the heat shield to assess how it held up
during its inaugural space foray.
The module—once in space—will be
powered completely by UltraFlex solar
arrays, the collected energy of which can
be stored in rechargeable lithium-ion
batteries. The two arrays on board consist of accordion-style-folded solar panels,
each about 19-ft wide, that are made of
high-efficiency, heat- and radiation-resistant gallium arsenide solar cells. Each
panel can provide 6,000 W of power,
“enough to power about six three-bedroom homes,” NASA says. n

in the displays of more mobile digital
devices.
“Because of their increased electron
mobility, compounds like IGZO can
provide brighter displays with higher
resolution,” says John Wager of OSU’s
School of Electrical Engineering and
Computer Science.
They also help to improve the energy
efficiency of devices. Because IGZO
transistors use less standby power, they
do not need to be charged as often—
meaning that phones that require
weekly, not daily, charging could be a
real possibility, say researchers.
“Amorphous oxide semiconductor
implementation appears on the verge of
exploding,” Wager says. “If the current
trend continues, in the next five years
most people will likely own some device
with these materials in them. This is a
breathtaking pace.” n

Imagine a world in which you could
incorporate any type of consumer electronic device—digital calendars, computer displays, GPS systems, and roomdarkening shades—into any type of glass
surface (think mirrors, windows, and
windshields). That world is just within
reach, thanks to the work of researchers
at Oregon State University.
In 2002, an OSU team developed
“transparent” transistors that it hoped
would “shake up the field of consumer
electronics.” Now—more than a decade
later—those amorphous oxide semiconductor materials are poised to make
a splash not just for their transparency but also for their clear ability to
improve current electronics offerings
on the market.
According to an OSU news release,

semiconductors”—based on indium
gallium zinc oxide (IGZO)—are being

See-through semiconductors set to ‘shake up’ consumer
electronics industry
A new mirror material reflects incoming
sunlight and banishes infrared radiation
into space to keep buildings cool.
Multilayered oxide mirror heats
up space to help cool buildings
Stanford University researchers have
developed a new material that they hope
will someday heat up space and cool
down rooftops.
The multilayered material—which
the scientists describe as a “one-two
punch”—works by reflecting visible and
infrared light away from buildings and
into space.
The cooling strategy may someday
make buildings much more energy efficient by reducing unwanted heat and,
thus, decreasing energy needs. Those
energy needs are staggering: Cooling
requirements were estimated a couple of
years ago to total 1 trillion kW∙h/year, a
significant fraction of the approximately
144 trillion kW∙h/year of total worldwide energy use (as estimated in 2008).
The Stanford scientists think their new
material may be able to ease that energy
consumption and cost, through a process
they call photonic radiative cooling.
That material, just 1.8-μm thick, is
composed of seven layers of silicon dioxide and halfnium oxide overlaid onto a
thin silver film. “These layers are not a
uniform thickness, but are instead engi-
13
ceramics in energy
neered to create a new material,” according to a Stanford press release.
The material’s structure is devised to
radiate infrared light at a particular frequency that pushes that energy directly
into space, rather than warming the air
around the building. It uses space as a
heat sink, rather than allowing that heat
to be absorbed into the atmosphere.
“Think about it like having a window
into space,” lead researcher and electrical engineering professor Shanhui Fan
says in the release.
But that is not all—the material also
functions as a mirror, reflecting up to
97% of sunlight.
“Together, the radiation and reflection make the photonic radiative cooler
nearly 9 degrees Fahrenheit cooler than
the surrounding air during the day,” the
release states.
The paper, published in Nature, is
“Passive radiative cooling below ambient air temperature under direct sunlight” (DOI: 10.1038/nature13883). n
Building stronger, taller towers of clean energy with high-strength
concrete technology
Credit: Bob Elbert; Iowa State University
If Iowa State University researchers have their way, towering wind turbines are about to get stronger and taller—thanks
to high-strength concrete technology and a $1-million investment from the Department of Energy.
Iowa State’s Sri Sritharan is researching a high-strength
concrete technology that has the potential to revolutionize
wind energy.
14
The DOE awarded the Iowa State team, lead by civil,
construction, and environmental engineering professor
Sri Sritharan, an 18-month grant to improve the team’s
Hexcrete concept developed during earlier work on reinforcing the concrete towers.
According to an Iowa State news release, Hexcrete
“uses precast and easily transportable components to build
hexagon-shaped towers from concrete panels connected to
concrete columns.”
“I think this will revolutionize wind energy,” says
Sritharan, who also heads the university’s Wind Energy
Initiative. “We won’t need to transport these big tubular
towers on the highways and we’ll harvest energy where it’s
needed.”
Sritharan says that the concrete-for-steel substitution
would provide additional benefits, including allowing towers taller than steel’s 80-m limit. Winds at 100 m elevations
and higher are faster and steadier.
Concrete towers also reduce production time, expand
wind energy’s geographic footprint, and cut costs. Concrete
towers can produce wind energy at a lower cost, and specifically reduce the costs associated with transporting the
towers.
During testing last year, the full-size segments and connections successfully handled the load the taller towers would
require—even under “extreme conditions.”
The additional monies will fund further research into the
manufacturing process needed to create these taller concrete
towers, which Sritharan believes could greatly impact not just
the energy industry, but the entire U.S. economy.
According to his project summary, “If used for the entire
height, the Hexcrete concept will eliminate transportation
challenges and engage a well-established U.S.-based precast
concrete industry in the wind tower business, thereby greatly reducing reliance on foreign steel and increasing the job
market in the U.S.” n

Electric cars powered by supercapacitor-packed body
panels could become roadway reality within five years
Although not nearly as energy dense
as lithium-ion batteries, these supercapacitors have advanced acceleration
capabilities and would provide an additional and quicker boost than what is
capable with conventional batteries,
say researchers.
“Supercapacitors are presently combined with standard lithium-ion batteries
to power electric cars, with a substantial
weight reduction and increase in performance,” says QUT postdoc research
fellow Jinzhang Liu. “In the future,
it is hoped the supercapacitor will be
developed to store more energy than
a lithium-ion battery, while retaining
the ability to release its energy up to 10
times faster—meaning the car could be
entirely powered by the supercapacitors
in its body panels.”
Liu reports that one full charge could
create enough power to propel the car up
to 500 km, which he says is in line with
the power of conventional cars, or double what an electric vehicle can provide.

of Technology and Rice University
has developed a high-capacity film
thin enough to place in panels, roofs,
doors, and floors of automobiles. The
super strong electrolyte–electrode
sandwich also can provide enough
power to recharge an electric vehicle
battery in minutes.
According to a QUT release, the
work, published in the Journal of Power
Sources and Nanotechnology, means that
supercapacitor-powered cars could
become a roadway reality before 2020.
“Vehicles need an extra energy spurt
for acceleration, and this is where supercapacitors come in. They hold a limited
amount of charge, but they are able to
deliver it very quickly, making them the
perfect complement to mass-storage batteries,” says QUT’s Marco Notarianni.
“Supercapacitors offer a high-power output
in a short time, meaning a faster acceleration rate of the car and a charging time of
just a few minutes, compared with several
hours for a standard electric car battery.”
Nunzio Motta is part of a team that is developing a thin, yet strong, supercapacitor film
that can be placed in the panels of a car door.

graphene films mixed with carbon nanotube clusters, are costeffective, so the price of this power is relatively low. According
to Nunzio Motta, professor at QUT, it also is a more earthfriendly way to provide high-power density.
“The price of lithium-ion batteries cannot decrease a lot
because the price of lithium remains high,” he says. “This technique does not rely on metals and other toxic materials either,
so it is environmentally friendly if it needs to be disposed of.”
Although these lightweight, yet high-strength, capacitors
could dramatically impact the auto industry, researchers say
that they also could find a home in other battery-powered
devices—devices where a quick charge would be desirable and
in demand—such as a faster-charging smartphone.
The papers are “High-performance all-carbon thin-film
supercapacitors” (DOI: 10.1016/j.jpowsour.2014.10.104) and
“Graphene-based supercapacitor with carbon nanotube film

etration by close to 50%.
The work of the NTU team, led by Sun Xiaowei, professor at the university’s School of Electrical and Electronic
Engineering, is published in Nature Communications.
“Our new smart electrochromic window is bifunctional; it is
also a transparent battery,” says Sun in an NTU news release.
“It charges up and turns blue when there is oxygen present in
the electrolyte—in other words, it breathes.”
To create their bifunctional battery–window, Sun and colleagues placed liquid electrolyte between two indium tin oxidecoated sheets of glass connected by electrical cables. On one of
the two sheets, they added Prussian blue, and to the other, a
strip of aluminum foil.
According to the release, “When the electrical circuit
between them is broken, a chemical reaction starts between
Prussian blue and the dissolved oxygen in the electrolyte,
turning the glass blue. To turn off the blue tint, the electrical
circuit is closed to discharge the battery, turning the Prussian
blue into a colorless Prussian white.”
Because it is energy independent and adjusts on its own,
Sun and team believe that their smart window could provide
“significant” cooling and lighting savings for homeowners and
businesses.
“Our technology is very attractive as a zero-sum consumption smart window,” says Sun. “Buildings owners and even
common households can reap energy savings right from the
outset and over the long term. Developers who are looking at
constructing environmentally friendly green buildings will find
our technology attractive for their building plans.”
The paper is “A bi-functional device for self-powered electrochromic window and self-rechargeable transparent battery
applications,” (DOI: 10.1038/ncomms5921). n

Stronger, greener cement-like material curbs
carbon emissions through diffusion
Accidents happen—as do “whoops” that become “eurekas.”
One such whoops-to-wow moment occurred in the lab of former
University of Arizona Ph.D. student David Stone.
That accident was Ferrock—an eco-friendly substitute for Portland cement that, according to a Tech Launch Arizona article, is
“significantly stronger.”
The manufacture of Portland cement accounts for 5% of total
global carbon emissions. Although more of it is being recycled
(some 140 million tons of concrete are recycled each year in the
United States, according to the Construction & Demolition Recycling Association), that does not stop researchers from seeking ways
to make the material more green.
Ferrock is being developed in collaboration with Tech Launch
Arizona. The “cement-like” material is “environmentally superior,
sustainable, and stronger than conventional cement,” according to
a Tech Launch article.
It also is carbon negative. Rather than releasing carbon, the
material traps carbon, diffusing and absorbing the element into
itself. The iron in Ferrock mixes with carbon, creating iron carbonate and becoming part of the material’s makeup.
“It has taken years to get just a basic understanding of the
chemistry involved,” says Stone in the article. “But this shouldn’t
be surprising since scientists are still trying to figure out Portland
cement and they’ve had 200 years. I am into this for the long
haul. Time is on our side since, in this era of global warming,
unsustainable processes like cement manufacture will have to give
way to greener alternatives.”
Stone, in collaboration with Tech Launch, licensed the technology from the University of Arizona and will commercialize the
invention with startup company Iron Shell LLC.
“The formation of Iron Shell promises to be very exciting,” says
Tech Launch Arizona’s Doug Hockstad. “The technology stands to
impact the world in a variety of ways, including both reduction of
carbon dioxide production and sequestration of other carbon dioxide production as well as recycling of waste products, such as steel
waste and, in some cases, recycled glass. For all that, this represents
an amazing engineering achievement that has the potential to create
a great, positive impact on the environment.” n

Greener de-icers and smarter snowplows could equal less bucks for state budgets
Although roadway salt shortages have
resulted in 10%–30% price increases
for the commodity this winter, the cost
of not using road salt is even higher,
according to the Salt Institute. Following
a one-day snowstorm, state economies
can experience up to $700 million in
losses from impassable roads.
To combat the cost of road salt—as
well as its impact on the environment—one Washington State University researcher is busy cooking up
greener ice-melting materials that use
fewer chemicals.
Xianming Shi’s studies in “road
ecology” at the university’s Center for
Environmentally Sustainable Transportation in Cold Climates—the nation’s
only center devoted to the impacts of
environmentally friendly snow and
ice control on our roads, wildlife, and
streams—have shown that combatting
winter requires a great deal of “highly
technical” science.
His smart snowplow comes with
sensors that enable plows to use less
salt. “Ordinary snowplows have at
least one sensor to measure pavement
temperature,” Shi says in a WSU
release. “Smart snowplows not only
read temperature but also residual salt
from previous applications, the presence of ice, and the amount of friction on the road. All of these readings
help operators apply less salt. In the
past, it was all done visually. By the
time you can see salt on the road, it’s
way too much and is going into the
vegetation and groundwater.”
In addition, his Maintenance Decision Support System, open-source software funded by the Federal Highway
Administration, provides insight about
road and weather conditions, salt supplies, and suggested application rates.
Shi also is at work improving beet
and tomato juice de-icers, which are less
corrosive but not as effective as their
chemical counterparts, and on a de-icerresistant concrete made with nanometer- and micrometer-sized particles that,
according to the release, “doesn’t break
down as quickly in the presence of salt
and chemicals, thereby extending the
life of roads and sidewalks.” Both have
the potential to further assist government in making winter roadways safer
and greener.
“To their credit, state and county
agencies are doing a very difficult balancing act,” says Shi. “They have to
look at safety first and sustainability
second. On top of that, they have budget constraints. So I think research is
crucial to help them out.” n

Floating project uses recycled
concrete and 3-D printing for
sustainable housing
State budgets could benefit from smarter snowplows that require less salt use.

Sweden already is known as one of
the most eco-friendly countries in the
world, and its eco-conscious inhabitants
continue to stay ahead of the curve. An
experimental studio of Swiss architectural
firm Belatchew Arkitekter, called Belatchew Labs, has unveiled a new project that
envisions floating housing complexes that
are sustainable, save land, and provide living space to young adults.
Called SwimCity, the project proposes to use recycled concrete to reduce
the often-heavy carbon footprint of construction. Combined with 3-D printed
techniques to fashion the structures,
SwimCity is not just sustainable, but
cost effective and efficient to build, too.
SwimCity proposes building with recycled concrete crushed into 40% coarse
and 25% fine aggregates, combined
with 10% recycled cement—from fly ash,
dross, and microsilica—and 15% water.
The recycled concrete would be

An aerial view of the SwimCity project—a floating housing
development that incorporates recycled concrete and 3-D
printing for sustainable construction and living.
3-D-printed into the desired structures to maintain the project’s efficiency and sustainability. Because the housing would
float on water, those structures’ possibilities are almost endless. The press release depicts simple hillside-encased structures
floating on the water in snowflake-arranged designs, but those
are just one possible configuration.
“The technological development in 3-D-printed concrete
has come very far. With SwimCity we show how the new
technology makes it possible for us to create unique buildings which today’s prefab industry is not capable of,” Rahel
Belatchew Lerdell, CEO and founder of Belatchew Arkitekter,
says in a SwimCity press release.
In addition to sustainable materials and building techniques, the project’s aqueous location also is a nod to its
eco-consciousness.
“Besides that water is an unused building ground, it is also
a potential energy source that can be used for energy in various ways, such as wave power and water–water heat pumps,”
according to the release.
Energy systems based on buoys connected to linear generators are estimated to be able to deliver 24 TW∙h each year
from the Baltic Sea’s waves, according to Belatchew. n

Ancient concrete structures, such as
the Pantheon and Coliseum in Rome,
stand strong and tall despite a couple
thousand years of wear. Moreover,
Roman concrete’s strength and durability is much more environmentally friendly than the ubiquitous Portland cement
used today.
Portland cement production requires
heating a limestone–clay mixture to
1,450°C, which releases a lot of carbon
in the process—enough to account for
7% of global carbon emissions.
Roman construction instead used
large chunks of rock (45%–55% by
volume) bound together by a mortar
composed of 85% by volume volcanic
ash mixed with water and lime, a formulation that requires much lower production temperatures and, thus, lower
carbon emissions.
A previous study led by University of
California, Berkeley, volcanologist and
scientist Marie Jackson already found
that Roman concrete’s binder contains
aluminum and has less silicon in comparison with the calcium, silicate, and
hydrate mixtures of modern concrete
binders. That aluminum content, in the
form of aluminum tobermorite, a rare
hydrothermal mineral, bestowed the
old concrete with higher stiffness, the
researchers thought.
A new study led by Jackson confirms
that unique aluminum-containing crystals that form in Roman concrete are
behind the material’s robust strength
and durability. The results, published in
the Proceedings of the National Academy
of Sciences, are particularly interesting to
efforts to make modern concrete more
durable and more sustainable.
“If we can find ways to incorporate
a substantial volumetric component of
volcanic rock in the production of specialty concretes, we could greatly reduce
the carbon emissions associated with
their production and also improve their
durability and mechanical resistance

Unique crystals prevent crack

Roman concrete strong
Ancient Roman concrete consists of coarse chunks of volcanic tuff and brick bound
together by a volcanic ash-lime mortar that resists microcracking, a key to its longevity and endurance.
over time,” Jackson says in a Lawrence
Berkeley National Lab press release.
To get a better look into concrete’s
structure, the team examined its mortar
using synchrotron X-rays.
The scientists used Berkeley Lab’s
synchrotron, the Advanced Light Source,
beamline 12.3.2 to X-ray 0.3-mm-thick
slices of Roman mortar. “We obtained
X-ray diffractograms for many different points within a given cementitious
microstructure,” Jackson says in the
release. “This enabled us to detect
changes in mineral assemblages that gave
precise indications of chemical processes
active over very small areas.”
The team put together analyses of
a reproduction and an actual sample
of the ancient concrete, in an effort to
understand what was happening within
the concrete. “Through observing the
mineralogical changes that took place in
the curing of the mortar over a period
of 180 days and comparing the results to
1,900-year-old samples of the original, the
team discovered that a crystalline binding
hydrate prevents microcracks from propa-
gating,” according to the release.
During curing, Roman concrete’s calcium-aluminum-silicate-hydrate binder got
stronger and tougher thanks to the growth
of platy strätlingite crystals in between the
volcanic material and the mortar.
“The mortar resists microcracking
through in-situ crystallization of platy
strätlingite, a durable calcium aluminosilicate mineral that reinforces interfacial
zones and the cementitious matrix,”
Jackson says in the release. “The dense
intergrowths of the platy crystals obstruct
crack propagation and preserve cohesion at the micron scale, which in turn
enables the concrete to maintain its
chemical resilience and structural integrity in a seismically active environment
at the millennial scale.”
These same structures are not present in Portland cement, which instead
has high porosity at those interfaces that
allows cracks to form and propagate.

Roman architectural mortar” (DOI:

Using additive manufacturing—a.k.a. 3-D printing—researchers at Princeton University printed
LED lights directly into a hard contact lens to
show that active electronics of varied materials can
be printed into complex shapes. Although the contact lens may look real, the engineers created the
device solely as a proof of principle.
“This shows that we can use 3-D printing to
create complex electronics, including semiconductors,” says Michael McAlpine, mechanical
and aerospace engineering professor and senior
author of the new research, in a Princeton press
release about the work. “We were able to 3-D
print an entire device, in this case an LED.”
The researchers used additive manufacturing to
print cube-shaped LEDs into a hard plastic contact
lens, using quantum dots as the “ink.” The device
incorporated five materials: “(1) emissive semiconducting inorganic nanoparticles, (2) an elastomeric

to handle these incompatibilities and also had to develop new

According to Yong Lin Kong, lead author and mechanical
and aerospace engineering graduate student, “For example, it
is not trivial to pattern a thin and uniform coating of nanoparticles and polymers without the involvement of conventional
microfabrication techniques, yet the thickness and uniformity
of the printed films are two of the critical parameters that determine the performance and yield of the printed active device.”
The scientists do not envision 3-D-printed electronics taking
the place of conventional manufacturing techniques—which primarily use lithography, a technique that is fast, efficient, and reliable. However, 3-D printing could be used in the future to create

A recent discovery in Israel shows that
olive oil likely was a part of human diets
and daily routines as early as the sixth
century B.C.
During the 2011–2013 dig at Ein Zippori in northern Israel, a team from the
Israel Antiquities Authority unearthed
ancient clay pots that contained residue
of equally ancient—some 8,000 years
ancient—olive oil. Their findings, published in the Israel Journal of Plant Sciences, support earlier research into the
domestication of the olive tree, and
researchers believe that olive oil was an
important part of diet and possibly was
used in primitive lighting.
According to Ianir Milevski and Nimrod Getzov, who oversaw the excavation
team, “This is the earliest evidence of
the use of olive oil in the country and
perhaps the entire Mediterranean basin.”

With the assistance of Dvory Namdar from Hebrew University of Jerusalem, they tested the organic remains contained in
about two dozen of the early Chalcolithic-era pottery. Samples
revealed the remains to be olive oil that had resided in the
ancient vessels, two of which date back to 5800 B.C.
Further, in comparing the oil to “modern” year-old oil, they
found a “strong resemblance … indicating a particularly high
level of preservation of the ancient material, which had survived close to its original composition for almost 8,000 years.”

New research published in Science shows how a couple
of University of California, Los Angeles researchers have
devised a patterned surface that resembles a bed of nails and
is superrepellent against all liquid assaults—a true superomniphobic surface.
“There are numerous superhydrophobic surfaces. Recently
some groups reported superoleophobic surfaces that can
superrepel oils and many solvents, but fluorinated solvents,
like 3M FC-72, have been out of reach,” says coauthor C.J.
Kim in an email. “We broke this final barrier, so our surface
superrepels ‘all’ available liquids at standard conditions—thus
superomniphobic.”
Most superhydrophobic and superoleophobic surfaces are
created by patterning surfaces with microstructures or by
applying a polymer coating.
Kim adds, “All existing superrepellent surfaces were based
on maximizing the liquid repellent property of a hydrophobic material by microstructuring its surface. This approach
worked down to superoleophobic surfaces. However, extreme
liquids like FC-72 perfectly wet the most hydrophobic material, so we concluded the existing approach wouldn’t work.”
“We set out to create surface microstructures that would
superrepel FC-72 purely by their geometric effect—regardless
of the chemical property of the material. First, we analyzed
to quantitatively predict what kind of microstructures would
successfully superrepel FC-72. Second, we developed fabrication to obtain such microstructures.”
Kim and colleague Leo Liu etched patterns of nails onto
the surface of silica, a “completely wettable material,” using
photolithography and reactive-ion etching. The duo found
that the trick was not to fabricate simple structures that
resemble nails or nailheads, but to add an overhanging lip to
the edge of the nailheads.
The lip prevents liquid from seeping into the space below
the nailheads, keeping the material’s surface from getting
wet. The team showed that its novel structures worked brilliantly to keep 14 liquids at bay on silica’s surface. They also

Refractories—
Engineered,
high-performance
‘silent partners’
By Eileen De Guire
T
hose who say the refractory industry
is old are right. The oldest known
furnace was built with sun-dried bricks in
Yarim-Tepe, Iraq, around 6000 B.C.1 In a
sense, too, the history of the ages—Stone Age,
Bronze Age, Iron Age—is a history of refractory technology. Stone Age era civilizations
used kilns to fuse and anneal glass, fire brick,
smelt ore, and make rudimentary cement
and gypsum. Civilizations that discovered the
metallurgy that gave name to the Bronze Age
and Iron Age gained technological advantages
over neighboring civilizations, usually through
improved weaponry that allowed them to
claim resources.
The Industrial Revolution exploded out of advances in ironmaking technology and steam power. Larger blast furnaces operated at higher temperatures, and invention of the rolling mill expedited metal forming for making machinery for manufacturing.
However, none of these metallurgical advances would be possible without prior seminal advances in furnace building and the
refractories within.
Refractories—the “silent partners” of manufacturing—make
possible anything made of metal, glass, or ceramic. They are
essential to petrochemical and chemical processing.
Hidden from view, advances in refractory engineering tend to
be known only to those in the field. However, every advance in
refractory technology goes straight to the bottom line, especially
26
in the steel industry, which consumes 65%–75% of global refractory production (see infographic, p. 27).
Steelmaking requires a wide range of refractory products,
each designed for specific functions. A basic oxygen furnace
(BOF), for example, is built with about 10 refractory brick types
to achieve uniform wear in the furnace. Other elements of the
steelmaking process, such as the tundish, ladle, and continuous caster, call for specialized refractory slide gates, purge plugs,
lances, and more.
Material savings translate to cost savings in manufacturing.
For example, improved design and installation reduced refractory usage in steelmaking from 60 kg/ton in 1950 to 15 kg/ton
in 2014—a 75% reduction in materials.2 Refractory service life
affects the bottom line, too. In the decade from 1986 to 1996,
LTV-Inland Steel (now defunct and absorbed into ArcelorMittal)
in the United States increased BOF converter lining heats from
2,000 to more than 48,000. Baosteel in China and Tata Steel in
India also increased BOF lining service lifetimes, although not
as dramatically. These advances are critical because unplanned
downtime in a steel plant is costly—up to $1,000 per minute.2
In the industries they enable, refractories of the future will be
expected to do more than handle heat, optimize energy usage,
and minimize environment impact. Controlling nanoscale features of the refractories will improve rigidity, toughness, thermal
shock resistance, and corrosion resistance. And incorporating
silica nanoparticles into castable refractory formulations will
enhance flow, resulting in a denser refractory.3 Future refractories may be bendable and self-healing, or may work to reduce
inclusions and other defects in molten metals.2
A recent report presented a refractory research roadmap with
a 10-year horizon that addresses materials testing, processing,
preparation, and synthesis to advance strategic goals, such as
energy and resource efficiency, while balancing economic and
material property requirements.4 The roadmap identified key
areas for research, including alternative raw materials, refractory
recycling, near-net shaping, rapid prototyping, surface engineering, bioinspired materials, and modeling and simulation studies.
Advancing refractory technology will require accurate hightemperature property data and high-temperature testing instruments—always a challenge.
As it has for millennia, refractories will continue to serve
as “silent partners” to the metal, glass, ceramic, and chemical industries. However, the partners know that this silence is
“golden” and speaks to their bottom lines in technical, environmental, safety, and economical terms.

ituated in the westernmost city of
Germany, Alpha Ceramics GmbH
in Aachen (ACA) offers a broad range of
services for the ceramic industry and related
sectors such as glass, refractory, concrete,
powder metallurgy, and environmental technology. ACA, a subsidiary of Laeis GmbH
(see sidebar), provides testing capacity for
new customers as well as in-house process
development and optimization. State-of-theart production scale machinery and equipment for material preparation, shaping, and
thermal treatment are available on site.
ACA offers its R&D and testing services to third parties,
and the equipment is also available for direct toll productions.
This possibility allows international customers to have newly
developed products manufactured at ACA for a limited time, for
example to test market acceptance or to bridge a time gap until a
production plant comes online. Products that are required only
in small lots and for which a separate production plant would
not be economical can be supplied recurrently on call order.
Emphasis of development activities at ACA focuses on applications. Through regular interaction with universities and other
R&D institutions, however, new basic research developments
also are integrated continuously. In addition, proprietary niche
products are developed and directly marketed, especially various
types of kiln furniture ranging from cordierite stacking aids to
highly sophisticated mullite–corundum pusher plates for rapidfiring purposes.
The following case studies show how ACA developed
unique adaptations to produce specialty refractories for
extreme environments.

Thermal treatment
Substantial internal investigations
have been conducted during the past
several years on rapid-firing of kiln
furniture. As a result, firing cycles have
been decreased substantially, resulting
in reduced energy consumption. This is
especially important for products with
a wall thickness up to 15 mm. Figure 3
shows the electrically heated top-hat kiln
used to fire mullite–corundum saggars.
To optimize this firing process, ACA
performed in-house differential thermal
analyses. Thermographs showed several
endothermic and exothermic reactions
between 450°C and 1,200°C during
heat-up of kaolinite. The main miner-
alogical transformation—thermal
decomposition of kaolinite followed
by reaction with alumina to form
mullite (3Al2O3∙2SiO2)—occurs during firing of saggars in an electrically heated kiln.8 Optimizing the
kiln firing cycle made it possible
to customize the microstructure of
the bonding phase of the refractory
material with regard to the special
requirements for the application.

entrapped air exceeds the green strength
of the saggar, it will burst or crack after
load release.
In principle, there are two approaches
to avoid texture damage caused by compacted air inclusion.
• Properly select an organic binder
system to increase green strength of the
pressed body to a sufficient level beyond
compression pressure of the entrapped
air; and
• Decrease the internal pressure
caused by entrapped air to a level below
the green strength of the pressed part,
simply by reducing the amount of air
inside the mold.
To avoid damage and lamination during production of the saggars described
above, ACA chose the second option.
This was realized with so-called vacuum
pressing technology, where the mold is
sealed and evacuated to a certain level
(typically less than 100 mbar) before
compacting the powder. ACA already
optimized this technology in cooperation with Laeis for a variety of applications.7 The mold cavity was evacuated
within seconds to a residual air pressure
less than 20 mbar. Doing so required
minimizing the volume to be evacuated,
which was achieved with a custom sealing technique. Cutting out de-airing
strokes keeps cycle times constant or
shortens them compared to conventional shaping technology. This new vacuum
device thus enhanced product quality
while maintaining output performance
at a comparable level.

calls for high loading density and exact
temperature and atmosphere control in
strict compliance with process requirements. The thermal processing plant for
this application is extremely complex,
requiring sophisticated components
and solutions that extend to the kiln
furniture used.

Cordierite stacking aids
A special application required complex-shaped stacking aids (Figure 5) with
extreme height variations within a single
piece. Normally this type of product
is slip-cast to avoid density differences
within the product. Shaping by hydraulic
pressing was not an option because dry
pressing does not allow such differences
in thickness, and pressing of semiwet
plasticized refractory mixtures often
results in macroscopic structural defects
or layer formation caused by entrapped
air (or both). Such structural defects can
be eliminated completely with vacuum
pressing. The combination of preparation of bodies with exactly defined plasticity and pressing under vacuum conditions allows homogeneous compaction
and shaping of complex products with
extreme dimensional differences in pressing direction. Additionally, failures, such
as cracks and out-of-specification dimensions, which can be caused by relatively
high shrinkage in the slip-casting process,
are reduced to a minimum when using
this semi-wet pressing technology.
Transparent spinel ceramics
One established process route for
producing polycrystalline transparent
spinel plates includes material preparation, uniaxial prepressing, cold isostatic
pressing (CIP), binder removal, and hot
isostatic pressing (HIP). When larger
sizes are required, CIP can bottleneck
the process chain. ACA and Laeis
worked with the Fraunhofer Institute
for Ceramic Technologies and Systems
(Dresden, Germany) to optimize the
uniaxial hydraulic pressing step and to
avoid CIP completely. Optimization of

everal challenges—as well as
opportunities—face ceramic engineering education today.
Although concerns regarding the
state of undergraduate ceramic
education in the United States
are not new,1–3 the 2014 meeting
of the Interagency Coordinating
Committee on Ceramic Research
and Development (ICCCRD)
recently reviewed the status and
future of ceramic engineering education. This committee, which has
existed for approximately 40 years,
consists of representatives from government agencies that have ceramics programs.4 At its 2014 meeting,
in addition to government agency
representatives, ICCCRD invited
speakers from Alfred University,
Pennsylvania State University, The
American Ceramic Society, American
Society for Engineering Education,
United States Advanced Ceramics
Association, and National Science
Foundation to provide their unique
perspectives on the state of ceramic
education in the U.S.
History of ceramic science and
engineering programs
In 1982, the ceramic honorary society Keramos
published a book by William Kriegel,1 a portion
34
www.ceramics.org | American Ceramic Society Bulletin, Vol. 94, No. 2
Capsule summary
of which he devotes to the history of
ceramic education. Ceramic engineering as a formal discipline began in
1894 with the creation of the Ceramic
Engineering Department at The Ohio
State University by Edward Orton Jr.
Four years later, Orton led the founding of The American Ceramic Society.
Many other universities followed Ohio
State’s lead and created ceramic engineering departments: Alfred University
(1900), Rutgers University (1902),
University of Illinois (1905), Iowa State
University (1906), and University of
Washington (1918). The 1920s saw
significant expansion in the number of
departments: University of Saskatchewan
(1921); Georgia Institute of Technology
(1923); West Virginia University,
North Carolina State University, and
Pennsylvania State University (1924);
University of Toronto (1925); Louisiana
State University, Missouri School of
Mines, and Massachusetts Institute of
Technology (graduate students only)
(1926); and University of Alabama and
Virginia Polytechnic Institute (1928).
Kriegel also traces changes in the
number of ceramic engineering programs. Beginning in the mid to late
1960s, many ceramics departments
began to merge with other departments
(e.g., metallurgy) to become materials
science and engineering departments.3
Subsequent curriculum additions reflected the growing technological importance
of semiconductors, polymers, and, much
later, biomaterials. Today, only two universities—Alfred and Missouri University
of Science and Technology—continue to
offer ceramic engineering degrees.5
Kriegel suggests that the lack of an
adequate definition of ceramics contributed to the decrease in ceramic
programs, because it failed to make the
field distinctive from other disciplines.
He noted that, in the 1940s, federal
agencies avoided use of the term ceramics, because it was not well understood
by nonexperts. Others—including ceramists—have made similar observations.2

background
Definition and image of ceramics
To the general public, ceramics represent objects of art or utility made from
clay, such as tableware. Similarly, glasses
refer to eyewear, windows, bottles, or stemware. Often, even individuals familiar with
technology do not recognize the numerous
applications for ceramics—as primary constituents of vital components in multilayer
capacitors, microwave components, highpurity silica fibers, engine components,
artificial hips, and many other applications. ICCCRD meeting attendees made
and reiterated the point that because of
their many unique optical, thermal, and
electronic properties, ceramics are often a
hidden but crucial material.
An attempt was made at the first
International Congress on Ceramics in
Toronto, Canada, in 2006, to broaden
the definition of ceramics by using the
phrase “any inorganic nonmetal.”6 This
definition goes a long way toward including materials beyond oxides, nitrides,
carbides, and borides—which are well
accepted as ceramics—to embrace also
chalcogenides (such as sulfides, selenides, and tellurides), optical materials at
all wavelengths (such as ZnS and ZnSe),
and forms of carbon (such as graphite,
diamond, and carbon nanotubes). By
this definition, many materials that are

Neither our academic institutions nor

Table 1. Gender bias in materials engineering

Engagement and diversity
White and Asian men have historically dominated the field of ceramics
(materials science and engineering and
related areas in physics and chemistry).
For example, The American Ceramic
Society elected only one female president
during its first 100 years (1899–1999).10
However, during the past 16 years,
the Society has elected four additional
women as presidents. Overall, the trend
of engaging more women in the science
and engineering side of ceramics is slowly changing. But a deficit of all underrepresented groups, including minorities
and people with disabilities, still persists
in ceramics as well as in most science,
technology, engineering, and mathematics (STEM) fields.11 To excel, these fields
must attract top talent regardless of gender, race, ethnicity, etc.
Women remain underrepresented
in materials engineering programs at
all levels and in professorial positions
(Table 1).12 According to the National
Academies “Beyond Bias and Barriers
Report,” “it is not lack of talent, but

passes fundamental material physics and
chemistry. Jones commented on the
decline of courses in many specialties
within the ceramics field, such as fractography and glass science. In part, this
reduction reflects retirement of professors in these fields, with little attempt
made to replace their expertise. When
an individual with a particular specialization retires, the institution must decide
whether to replace her or his expertise.
With the growth of new topics, such as
energy materials and nanotechnology, it
is not surprising that some traditional
areas of ceramic research are no longer a
primary focus.
Gary Messing, head of the Materials
Science and Engineering Department at
Pennsylvania State University, touched
on this topic in his presentation. He
presented examples of materials science
and engineering options that include
ceramics and electronic or photonic
materials—many of which are ceramics as
well. Messing also noted that a graduate
program’s rank is based on the quality
and extent of its research rather than on
undergraduate teaching, leading to an
emphasis on cutting-edge topics. Some
fields that seem more relevant today simply have caught the attention of media,
giving the appearance of more promise
for careers (e.g., computer science and
nanotechnology). In addition, degrees
now require fewer course hours, leading
to a reduction either in number of courses taught or time spent on each topic.
Several years ago, Katharine Faber,
materials science professor at California
Institute of Technology, pointed out that
modern teaching techniques, such as
“Materials by Design,” could also enhance

Although women tend to be touted
as masters of teamwork, the generality is
infrequently connected to engineering
careers. There also seems to be a lack of
appreciation for engineering’s contributions to society. For example, some view
healthcare as a more “giving” or altruistic
field. Additionally, the lack of widespread
understanding of what ceramics are and
how they contribute to engineering solutions to society’s grand challenges naturally begets a failure to appreciate careers
in ceramic science and engineering.
Exciting careers with above-average
U.S. salaries are available to ceramic scientists and engineers, but young people
embarking in higher education seem
not to have discovered the profession's
opportunities. Concurrently, the cost
of education continues to increase, and
debts incurred by some bachelor degree
graduates can seem daunting.14
ACerS executive director Charlie
Spahr reported that the Society recently
formed the Ceramic and Glass Industry
Foundation, one aim of which will be to
support scholarships and internships in
ceramic and glass science and engineering.
The CGIF mission is to ensure that industry is able to attract and train the highestquality talent possible by increasing awareness of the field and facilitating the choice
with experiences such as internships.
Employment
The presence of lucrative employment
opportunities is a primary driving force
for enrollment in any university discipline. The ceramics community continues
to debate the need for additional ceramic
engineers in the workforce. Lynnette
Madsen, program director of Ceramics
www.ceramics.org | American Ceramic Society Bulletin, Vol. 94, No. 2

at the National Science Foundation,
raised the issue of whether the number
of new ceramic science and engineering
graduates is sufficient to meet workforce
needs.15 However, when discussing job
shortages, one must ask whether salary
structures reflect the need for a particular
expertise. In this respect, there is insufficient data to suggest that the need for
ceramic engineers is great enough for
salary structure to differ significantly from
that of other engineers.
Is there a shortage of ceramic engineers and glass scientists in terms of
the needs within U.S. companies? A
recent article published by Corning
Incorporated claims that “students
with expertise in glass families that are
industrially relevant (particularly silicate
glasses and glass-ceramics) are more
likely to be hired into a position in
industry and also require less on the job
technical training after being hired.”16
Government reports project a shortfall
of STEM professionals (see sidebar
above),17 but other reports suggest that
there is no shortage of scientists and
engineers in the U.S. workforce.18
Douglas Freitag, technical director of
the U.S. Advanced Ceramic Association,
said that its member companies have difficulty finding job candidates with the
requisite expertise to apply to polymerand ceramic-matrix composites. According
to Freitag, there is no known ceramic
composite training programs. Also, export
control issues restrict hiring to U.S.
citizens, further limiting the job pool.
Norman Fortenberry, executive director
of the American Society of Engineering
Education, also stressed this point.

“Economic projections point to a need for approximately 1 million more STEM professionals than the U.S. will produce at the current
rate over the next decade if the country is to
retain its historical preeminence in science
and technology. To meet this goal, the U.S.
will need to increase the number of students
who receive undergraduate STEM degrees by
about 34% annually over current rates.”

College Charles P. Steinmetz Symposium.
Future opportunities
Although this section moves beyond the
discussion at the ICCCRD meeting and
suggests avenues to consider, it addresses
primarily the issues raised already. The
following is not comprehensive in its treatment of education as a whole, because
other sources exist for those purposes. For
example, recent National Academy reports
provide many excellent insights into
improving engineering education at the
undergraduate level.19,20
Image of ceramics
One of the primary recommendations
for growth of ceramic science and engineering is to better define and accept
what is ceramic. As mentioned previously, a possible definition that encompasses most of the materials of interest is
“any inorganic nonmetal.” Students and
the public need to be better informed
about the significance of ceramic materials and their importance in technology,
perhaps through press releases, books,
videos, and even museums.
Pedagogy and curricula
To provide the best possible education to ceramic science and engineering
undergraduates, educators should fully
explore and adopt state-of-the-art teaching methods. Educators should also
focus on a broad spectrum of ceramic
technologies and properties—nanotechnology, glass and optics, and electronic
materials as well as the fundamental
aspects of the materials, such as phase
equilibria and mechanical properties.
A recent education report to U.S.
President Barack Obama (see sidebar
below)17 ties together issues of diversity
and teaching, and the report also endorses
using evidence-based teaching methodologies to effectively reach more students.20
At present, the field of ceramics may
suffer from too few faculty members at
any given institution and, consequently,
few students being taught or trained in
the field. Courses team-taught by several
experts in a particular aspect of ceramic
science, regardless of location, are one
way to make use of the best expertise
available.
Naturally, increased funding of ceramic
material research would increase the
number of graduate students in this area.
Individuals entering graduate programs frequently make decisions on specialties based
Evidence-based teaching reaches students
“Better teaching methods are needed by university faculty to make courses more inspiring, provide
more help to students facing mathematical challenges, and to create an atmosphere of a community of STEM learners. Traditional teaching methods have trained many STEM professionals,
including most of the current STEM workforce. But a large and growing body of research indicates
that STEM education can be substantially improved through a diversification of teaching methods.
These data show that evidence-based teaching methods are more effective in reaching all students
especially the ‘underrepresented majority’—the women and members of minority groups who now
constitute approximately 70% of college students while being underrepresented among students
who receive undergraduate STEM degrees (approximately 45%). This underrepresented majority is
a large potential source of STEM professionals.”

gration rules or limits access to some
technical fields.
Diversity, accessibility, and attraction
Programs to attract and retain more
women, minorities, and other underrepresented groups into material science,
and ceramics in particular, should be
expanded. On the professional level, for
example, companies and academic institutions may need to find creative solutions for accommodating young couples
seeking paired positions. Already, some
funding agencies, such as NSF, have
established mechanisms for “stopping
the clock” for a year to care for a newborn. Universities, funding agencies,
and companies may find policies that
meaningfully address work–life balance
will help them recruit the best talent
possible. In addition, underrepresented
groups need opportunities to assume
leadership roles and be recognized for
their successes.
Undergraduate scholarships can help
guide a student’s decision of a college
major. Ceramic science and engineering
would benefit from increased funding
for this purpose. Industries interested in
hiring individuals with a background in
ceramics and glass could help sponsor as
well as provide financial support to students in ceramic science and engineering.
Evolving ceramic science and engineering education continues to be highly
relevant to the innovation of new materials. Many universities have incorporated
required courses on mathematics, engineering, chemistry, and physics of these
materials into materials science and
engineering (or related areas) curricula.
Consequently, there are fewer courses in
clay technology, ceramic and glass processing, and glass technology.
Building a vibrant ceramic engineering profession depends on attracting
the best talent possible and instilling in
them a passion for this class of materials.
Underrepresented groups have a key role
in strengthening the ceramic community and contributing to its vitality and
growth. Economic factors, such as cost of
education, availability of research funds,
and job opportunities, play a major role
in the health of this community across
the entire education spectrum—from
when a student selects a major to when a
new professor begins a career.
Employment
Employment opportunities and
research funding are major factors in a
student’s selection of an undergraduate
major or a graduate degree. If companies
are experiencing a shortage of qualified
candidates for ceramic jobs, offering
cooperative education programs and
internships would help more students
discover and enter this field. Increased
availability of research funding, either
through industry or government, would
increase graduate student numbers.
Developing a better path forward for
international students who come to the
U.S. for their education also is a priority
so that these highly skilled workers can
use their expertise in the U.S. workforce.
Ultimately, the fate of career opportunities for noncitizen students lies in the
political realm, which determines immi38

Engineering Ceramics Division Meeting
(Credit for all photos: ACerS.)
Record-breaking 1,100 attend 39th ICACC in Daytona Beach, Fla.

Œ
“
This year’s conference was a great success and was very well received,” says
Michael Halbig, chair of the Engineering Ceramics Division. “It has become the
premier international conference on advanced ceramics and composites in the
world, with strong participation from students and young professionals as well as
scientists and engineers from all corners of the globe.”
The conference opened with the Mueller Award Lecture by David Clarke (Harvard University) on the topic of thermal barrier coatings for gas-turbine engines.
Sanjay Mathur (University of Cologne, Germany) followed with the Bridge Builder
Award Lecture and showed how nanomaterial functionality derives from chemical
processing pathways.
In the first plenary talk, Cato Laurencin (University of Connecticut) described his
cross-disciplinary research at the intersection of materials science and biology.
This new field, known as regenerative engineering, uses materials—including
ceramics—to regenerate bone, muscle, cartilage, and tendons. The session ended
with a plenary talk by Kazushige Ohno of Ibiden Co. (Japan) on advances in diesel
particulate filters. Diesel soot, he says, is the second largest contributor to global
warming after CO2 emissions.
Ž
There was more than the technical program for attendees. Vendors presented their
products and services in
the exposition hall,
where poster sessions,
tasty receptions, and the
annual Schott Glass drop 
competition also were
held. Always looking to the future, organizers planned plenty of events for students and
young professionals, such as the Global Young Investigators Forum, Young Professionals
Network reception, and a mentoring workshop.
The growing number of presentations and activities at ICACC bear witness to the impact
of the event on the field of engineered ceramics and glass. The event brings a significant
amount of business to Daytona Beach and Volusia County every year, too.

Plenary talks by
Kent Budd of 3M,
Greg Rohrer of
Carnegie Mellon University, and Hiroshi
Funakubo of Tokyo Insitute of Technology drew full audiences to their seats
‘
each morning of the conference. The
talks supplied a daily momentum that continued through presentations in 11 conference
symposia, spanning topics from ceramic composites to computational design to LEDs
and photovoltaics.
Student poster and oral presentations
highlighted diverse work being done by
young scientists, and the conference
continued to support and recognize that
work. “This year EMA selected and highlighted Young Professional Network speakers
in nearly every symposia and provided them
with registration support,” Haugan says.
“The conference continues to emphasize
student participation—approximately 20%
attendees are usually students.”
The last day of the conference wrapped
up with a special—and unique—session.
Speakers Ian Reaney of the University
’
of Sheffield and Brennecka shared their
familiarities with failure in the laboratory, detailing stories that elicited laughs and nods of
relatability from across the audience. As Reaney put it, “It’s not if, but when, you get things
wrong.” It is ultimately how you move forward from those wrongs that can make it all right. n

book review
Associate editor
Stuff Matters:
Exploring the
marvelous materials
that shape our
man-made world
by Mark Miodownik
Mark Miodownik has one sincere
message: Stuff really matters.
Miodownik, a science communicator
and materials science and engineering
professor at University College London,
echoes that message through his passion
for materials in the book Stuff Matters.
The book is not an entirely technical nor comprehensive history, dissection, or explanation of materials,
but rather an entertaining meander
through the everyday world, exploring
materials along the way. Stuff Matters
is a good introduction to, or reminder
of, the world of materials science by
connecting stuff to its recognizable
place in the world.
“The material world is not just a display of our technology and culture, it is
part of us,” Miodownik reflects in the
book. “We invented it, we made it, and,
in turn, it makes us who we are.”
By directly connecting materials to
our lives, the book becomes a compelling champion for the wonder and
importance of materials. It removes the
abstraction, instead inserting an emotional, personal connection to materials.
Miodownik uses a simple—yet carefully articulated—photograph of himself
sitting on the rooftop of his flat to illustrate the wonders of 10 materials present
in the photograph.
Miodownik writes in the book’s introduction, “For each [material] I try to
uncover the desire that brought it into
being, I decode the materials science
Mark Miodownik, author of Stuff Matters,
examining stuff.
behind it, I marvel at our technological
prowess in being able to make it, but most
of all I try to express why it matters.”
Those 10 materials, each with a
descriptor that doubles as chapter title,
are steel (indominatable), paper (trusted), concrete (fundamental), chocolate
(delicious), foam (marvelous), plastic
(imaginative), glass (invisible), graphite
(unbreakable), porcelain (refined), and a
biomedical implant (immortal).
Miodownik continues in the introduction, “Each new chapter presents not
just a different material but a different
way of looking at it—some take a primarily historical perspective, others a more
personal one; some are conspicuously
dramatic, others more coolly scientific;
some emphasize a material’s cultural life,
others its astonishing technical abilities.”
Without being abstract, Miodownik
explores the microscopic and macroscop-
American Ceramic Society Bulletin, Vol. 94, No. 2 | www.ceramics.org
ic world of materials science to explain
why each material is unique—and special.
To aid these explanations, the book is
dotted with hand-drawn figures and
diagrams, making the science accessible,
the concepts clear, and the story overall
entertaining.
In the end, Miodownik philosophizes
about chocolate, reminisces with paper,
and awes over ceramics. His enthusiasm and awe shine through the prose,
making the book a light and easy read.
Although the book meanders a bit, this
style also plays into its informality—the
reader almost feels as if she is sitting on
the rooftop with Miodownik, letting
him babble excitedly about each material
around him.
Stuff Matters is an entertaining introduction to the utility of materials for
anyone unfamiliar with materials science. For those more familiar, it is easy
and entertaining, a good reminder of
the field’s broad purpose, and an inspiration for how to effectively talk about
materials science to nonexperts. n

The successful applicant will be appointed as a University Professor at the RWTH
Aachen and at the same time granted leave in order to head the DLR Research
Department.
RWTH Aachen and DLR intend to intensify their collaboration with respect to
research and teaching in the area of fibre reinforced ceramics and increase the
common usage of resources. Hence, we are looking for a personality with excellent scientific qualifications in the area of structural ceramics with a specific focus
on ceramic matrix composites capable to represent this topic in the teaching
curriculum of the RWTH Aachen. Lectures in the amount of two hours per week
and excellent teaching and didactic qualifications are expected. The application
documents must therefore include a list of successfully taught courses. Habilitation
or equivalent scientific experience in the area of structural ceramics, especially
ceramic composite materials, is expected.
At the DLR-Institute for Materials Research the successful applicant assumes
responsibility for the scientific direction, organization, economic success and the
personnel of the department “Structural and Functional Ceramics”. Together
with more than 15 scientists and technicians he/she further develops the research
focus of the department in line with the strategy of the DLR and the institute. The
scientific topics include material development and synthesis, characterization of
materials, simulation of component and damage behaviour and the development
of processes to manufacture prototype components for rig tests. Apart from
technical and scientific skills applicants are expected to have a formal education
and proven track record in leadership and management of scientific and technical
employees. In addition to its scientific excellence the institute is striving to intensify the transfer of the research results into industrial products. The successful
candidate is therefore expected to have a proven track record of successfully
acquiring and executing collaborations with partners from industry and academia
and to have access to an extensive network of partners relevant for our research
topics. Ideally he/she has industrial working experience in Germany as well as
abroad.
Please send your application to: Prof. Dr. Heinz Voggenreiter, Institut für WerkstoffForschung, Linder Höhe, 51147 Köln, Germany. Deadline for applications:
April 17, 2015.

deciphering the discipline
Having an internship in the ceramics
industry allowed me to see firsthand the
importance, as well as the complexity, of
the relationship between technology and
policy—and it showed me that I wanted
to learn more. This past summer, I had
the opportunity to do just that as an
intern with the United States House
Committee on Science, Space, and
Technology in Washington, D.C. I have
been interested in politics for much of
my life, so an internship in the nation’s
capital was a dream come true.
The University of Virginia’s Policy
Internship Program of the School of
Engineering and Applied Sciences,
which matches engineering students
with policy internships, gave me the
resources and encouragement to pursue
this longtime goal by matching me with
the House Science Committee. The
committee has jurisdiction over nondefense federal scientific R&D, which
includes agencies such as the National
Aeronautics and Space Administration
(NASA), Environmental Protection
Agency (EPA), and National Science
Foundation (NSF).
Science Committee hearings serve as
a forum for policy makers and scientists
to discuss relevant issues. Science and
policy have a close relationship, so the
involved parties must communicate and
work together to develop outcomes that
are appealing to both sectors. On average, the committee held two hearings
per week relating to programs or issues
in its jurisdiction. Throughout the summer I attended hearings and bill markups and worked on research projects
to help committee members and staff
prepare for the hearings. Sitting in on

being a part of the process
was a thrilling experience,
and I learned more than I
ever could have imagined.
Funding is often the
hot topic at committee hearings, but there
are other fundamental
issues at stake as well.
Conversations often
center on the role of the
government (especially
federal funds) in research,
whether funds should
support basic or applied
research, and who should
be able to benefit from
the results. Similarly,
there often is debate
about the transparency of
research that is federally
funded or majorly affects
the public. Conversations
