36. Water oxidation : From Molecular Systems to Functional Devices
Sammanfattning : The production of hydrogen gas, through the process of water splitting,is one of the most promising concepts for the production of clean andrenewable fuel.The introduction of this thesis provides a brief overview of fossil fuelsand the need for an energy transition towards clean and renewable energy.

37. Artificial Water Splitting: Ruthenium Complexes for Water Oxidation
Sammanfattning : This thesis concerns the development and study of Ru-based water oxidation catalysts (WOCs) which are the essential components for solar energy conversion to fuels. The first chapter gives a general introduction about the field of homogenous water oxidation catalysis, including the catalytic mechanisms and the catalytic activities of some selected WOCs as well as the concerns of catalyst design.

38. New Approaches for Chemical Analysis of Single Cells and Vesicles
Sammanfattning : Exocytosis is the major cell-to-cell communication process in the nervous system, involving the conversion of an electrical signal (e.g. action potential) to a chemical one. Signaling molecules like neurotransmitters, hormones and/or peptides are stored in vesicles inside the cell. LÄS MER
39. Electrocatalysts for sustainable hydrogen energy : disordered and heterogeneous nanomaterials
Sammanfattning : With the current global greenhouse gas emissions, our remaining carbon budget is depleted in only 7 years. After that, several biophysical systems are predicted to collapse such as the arctic ice, coral reefs and the permafrost, leading to potentially irreversible consequences. LÄS MER
40. 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
