1. Rhodium diesel-reforming catalysts for fuel cell applications
Sammanfattning : Heavy-duty diesel truck engines are routinely idled at standstill to provide cab heating or air conditioning, and in addition to supply electricity to comfort units such as radio and TV. Idling is an inefficient and unfavorable process resulting in increased fuel consumption, increased emissions, shortened engine life, impaired driver rest and health, and elevated noise. LÄS MER
2. Ring-opening catalysts for cetane improvement of diesel fuels
Sammanfattning : The global oil refining industry with its present product distribution essentially shifted towards fuels such as gasoline and diesel will most likely hold the fort for considerable time. However, conditions are changing and refinery survival will very much depend on long-term planning, process and product flexibility and being at the frontiers of refining technology, a technology where catalysts play leading roles.

3. A Study of Propane and Propene Ammoxidation over the Mo-V-Nb-Te-Oxide System
Sammanfattning : The ammoxidation of propane is commonly regarded as being the future route for producing acrylonitrile, and the Mo-V-Nb-Te-oxide system studied here has thus far been seen as the most promising candidate for achieving this. Yields of up to 62% have been presented very elegantly in the patent literature. LÄS MER
4. Molecular and ultrastructural analysis of Tpr, a nuclear pore complex-attached coiled-coil protein
Sammanfattning : Anchored in the nuclear envelope, nuclear pore complexes (NPCs) are large multiprotein complexes which serve as the gateway for nucleocytoplasmic transport. In vertebrates, a 267kDa protein termed Tpr has been localized to the nucleoplasmic side of the NPCs. The function of Tpr has remained largely elusive. LÄS MER
5. Oxygen Storage Chemistry of Nanoceria
Sammanfattning : The versatile redox chemistry of ceria (CeO2) originates from its Ce4f electron, which plays the key role in changing the oxidation state of Ce between +IV and +III. Ceria is, among other things, a material that can act as a powerful oxygen buffer with a high oxygen storage capacity (OSC). LÄS MER
