21. Surface Charge Dynamics on Polymeric Insulating Materials for High Voltage Applications
Sammanfattning : To meet increasing demands in electric energy, it is essential to enhance production of electricity from renewable energy sources (solar, wind and hydro). Such generation sites, however, are usually separated from consumption sites by long distances. LÄS MER
22. Theoretical and experimental studies of surface and interfacial phenomena involving steel surfaces
Sammanfattning : The present work was initiated to investigate the surface- and interfacial phenomena for iron and slag/iron systems. The aim was to understand the mechanism of the effect of surface active elements on surface and interfacial properties. LÄS MER
23. Experimental Investigation of Cavitation-Bubble-Induced Atomization
Sammanfattning : Improving the efficiency and lowering the emissions of internal combustion engines (ICE) has been drawing increased attention because climate change caused by greenhouse gases and the need to reduce emission harmful to human health, and stricter legislation on the emissions from liquid-fueled transportation is implemented. Design of the liquid fuel atomizer, which atomizes the fuel delivered into the combustion chamber by the fuel injection system, is important because a good atomization, which facilitates the evaporation of fuel and improves the fuel-air mixture, leads to higher efficiency and lower emissions of ICE.

24. Integration of Surface Acoustic Wave and Microfluidic Technologies for Liquid-Phase Sensing Applications
Sammanfattning : This thesis discusses a new concept for construction of a novel SAW in-liquid sensor employing surface acoustic wave resonance (SAR) in a one-port configuration. In this concept, the reflective gratings of a one-port SAW resonator are employed as mass loading-sensing elements, while the SAW transducer is protected from the measurement environment, reducing power losses significantly.

25. Chemical-Looping Combustion with Liquid Fuel — Operation in a 300W Chemical-Looping Combustor
Sammanfattning : Chemical-looping combustion (CLC) is a promising technology for future energy production based on combustion of fossil fuel with inherent CO2 separation. In comparison to other carbon capture technologies there is no need for energy demanding gas separation using CLC in order to obtain pure CO2. LÄS MER
