1. The Compression/Absorption Heat Pump Cycle - System Simulations
Abstract : From the results presented in this thesis it is clear that the compression/absorption heat pump cycle offers several advantages over other types of heat pumps. In many cases it gives a higher or equally high COP compared with the single-fluid compression heat pump but also the smaller SCD (i.e. READ MORE

2. NOx Storage and Reduction Catalysts. Reduction with Hydrogen and the Influence of Water and Carbon Dioxide
Abstract : Environmental concern has increased over the past several years and resulted in stringent emission legislation on NOx, CO, and hydrocarbon emissions from automobile exhausts. Moreover, the demands to improve the fuel efficiency of engines and to lower the CO2 emissions have increased, and a way to meet this is by using lean burn engines which operate with oxygen excess.

3. Interactions of ionic molecular clusters H+(H2O)n, H+(NH3)1(H2O)n and H+(pyridine)1-3(H2O)n with heavy water in cluster beam experiments
Abstract : Molecular cluster ions are fascinating subjects of study. Bridging the size gap between molecules and bulk, they often display non-trivial size dependent behavior and properties. READ MORE

4. NH3-SCR over Cu-zeolite catalysts: activity and deactivation studies
Abstract : NOx emission is one of the major contributors to air pollution especially in the urban environment. The most frequently applied technique to reduce NOx from diesel engine is to employ ammonia selective catalytic reduction (NH3-SCR) using Cu‑zeolite as the catalyst. READ MORE

5. Reaction kinetics of NH3-SCR over Cu-CHA from first principles
Abstract : Ammonia-assisted selective catalytic reduction (NH3-SCR) is an advanced technology to reduce nitrogen oxide (NOx) emissions from lean-burn engines. NH3 is added to the exhaust gas and reacts selectively with NOx, forming N2 and H2O. READ MORE
