The Norwegian Chemical Society
The organization and its contribution
to chemistry in Norway and to
Nanotechnology
Norsk Kjemisk Selskap
Nina Aas, President NKS
Agenda
• NKS in general
– History, comparison with other chemical
societies, aims and ambitions, organization
• NKS activities
– Board, local branches, professional divisions
• Examples relating to nanotechnology
– Catalysis and gas adsorption
Norsk Kjemisk Selskap

Norsk Kjemisk Selskap
• Professional divisions
1. Analytical chemistry
2. Nutrition and food
additive technology
3. Catalysis
4. Chemometrics

7. History of chemistry
Catalysis
• Catalysis is an atomic-scale phenomenon.
• Catalysis has a long history in Norway.
• Refinery and petrochemical industry use
catalysts.
• Bimetallic catalysts are of special interest:
– Hydrodesulfurisation
– Catalytic reforming (Pt/Sn and Pt/Re)
– Fischer Tropsch reaction

ETS-4
Norsk Kjemisk Selskap
Karl Petter Lillerud, Uni Oslo
Advantages of ETS-4
• Ion-exchanged material (Sr) more stable
– Delayed dehydration
– Controlled decrease in lattice dimensions
– Increased thermal stability
• Effect of temperature
– Pore narrowing
– Cation relocation
– Reduction of effective diameter

Conclusions
• Norway has a long history of chemistry.
• There is a good basis for working with
nanotechnology.
• NKS is an active society – join now!
