1. Evaluating Cathode Catalysts in the Polymer Electrolyte Fuel Cell
Sammanfattning : The polymer electrolyte membrane fuel cell (PEMFC) converts the chemical energy of hydrogen and oxygen (air) into usable electrical energy. At the cathode (the positive electrode), a considerable amount of platinum is generally required to catalyse the sluggish oxygen reduction reaction (ORR). LÄS MER
2. "Gör dig en sång uti mitt bröst". Musikalisk gestaltning i ljuset av herrnhutisk tradition
Sammanfattning : .... LÄS MER
3. Studies on the Epidemiology of Open-angle Glaucoma
Sammanfattning : Glaucoma is a common disease in the elderly population. Open-angle glaucoma (OAG) is the predominant form of glaucoma. Chronic simple glaucoma and capsular glaucoma, characterized by the occurrence of pseudoexfoliation in the anterior eye segment, are the most frequent types of OAG. LÄS MER
4. Ljungan Virus Replication in Cell Culture
Sammanfattning : Ljungan virus (LV) is a recently identified picornavirus of the genus Parechovirus. LV has been isolated from voles trapped in Sweden and also in the United States. LV infected small rodents may suffer from diabetes type 1 and type 2 like symptoms, myocarditis and encephalitis. LÄS MER
5. Transition Metal Hydrides : Biomimetic Studies and Catalytic Applications
Sammanfattning : In this thesis, studies of the nature of different transition metal-hydride complexes are described. The first part deals with the enantioswitchable behaviour of rhodium complexes derived from amino acids, applied in asymmetric transfer hydrogenation of ketones. LÄS MER
