2. The Impact of Hydrocarbon and Carbon Oxide Impuritiesin the Hydrogen Feed of a PEM Fuel Cell
Abstract : The proton exchange membrane fuel cell generates electricity from hydrogen and oxygen (from air) through electrocatalytic reactions in an electrochemical cell. The Pt/C catalyst, commonly used in PEM fuel cells, is very sensitive to impurities that can interact with the active catalyst sites and limit fuel cell performance. READ MORE

4. Physiologically based pharmacokinetic modeling in risk assessment - Development of Bayesian population methods
Abstract : In risk assessment of risk chemicals, variability in susceptibility in the population is an important aspect. The health hazard of a pollutant is related to the internal exposure to the chemical, i.e. the target dose, rather than the external exposure. READ MORE

5. Acute toluene effects on neurotransmission in the central nervous system
Abstract : The aim of this thesis was to develop a method to study the effects of toluene in the central nervous system of the rat. Microdialysis on awake rats was used to study toluene's effects on the transmission of dopamine, acetylcholine, glutamate and aspartate in the striatum, and on GABA in the striatum, the cerebellum and the globus pallidus.
