2. Dual Scale Porosity and Interlaminar Properties of Composite Materials
Abstract : In the strive towards reduced fuel consumption and lower emissions, low structural weight is becoming a key factor in the design of advanced vehicle and aerospace structures. Whereas most traditional construction materials are seemingly reaching their limitations, composite materials with their high specific properties offer possibilities to further reduce weight.

5. Biogeochemical Processes in Denitrifying Woodchip Bioreactors and their Application in the Mining Industry
Abstract : This thesis evaluates passive denitrifying woodchip bioreactors (DWBs) for the removal of nitrate (NO3-) in neutral pH mine drainage, where water is passed through a carbon-rich porous matrix (e.g. woodchips) for the reduction of NO3- to nitrogen gas. READ MORE
