16. Structure, Morphology, and Catalytic Properties of CuOx/CeO2 Model Catalysts
Sammanfattning : Cerium dioxide, or ceria, is a chemically stable oxygen ion conducting material with a capacity to store and release oxygen, and is therefore extensively used in combustion catalysts. The Cu-Ce-O system has been identified as one of the most active catalysts for the combustion of carbon monoxide. LÄS MER
17. A Study of some Neutron-rich Isotopes of Lanthanum, Cerium and Praseodymium by Means of the Fast Chemical On-line Separation Technique SISAK
Sammanfattning : .... LÄS MER
18. Preparation and characterization of sputtered metal oxides and nitrides for optical applications
Sammanfattning : Sputter deposited metal oxide and nitride thin films have been studied for energy-efficient window applications. Coatings, for both static and dynamic control of radiative heat transfer through windows, were optically characterized. As metal base in static solar selective coatings, semi-transparent TiN and ZrN films have been investigated. LÄS MER
19. Oxygen Vacancy Chemistry in Ceria
Sammanfattning : Cerium(IV) oxide (CeO2), ceria, is an active metal oxide used in solid oxide fuel cells and for the purification of exhaust gases in vehicle emissions control. Behind these technically important applications of ceria lies one overriding feature, namely ceria's exceptional reduction-oxidation properties. LÄS MER
20. Coated Ferritic Stainless Steels as Interconnects in Solid Oxide Fuel Cells
Sammanfattning : Solid oxide fuel cells (SOFCs) have gained increased research interest as they arepromising devices for a decentralized and clean electricity and heat production. Severalmaterial challenges have to be solved to reach sufficient efficiencies and life times. LÄS MER
