1. Micro- / Meso- Scale Dielectric Strength Testing of Fibre Composites
University essay from Umeå universitet/Institutionen för fysikAbstract : Glass fibre composites are common materials used in high voltage applications as insulating materials that provide good structural integrity. The aim of this thesis is to develop a method of studying the failure in such materials by measuring the dielectric strength on micro- and meso- scale samples, consisting of single fibre filaments and fibre bundles respectively embedded in epoxy resin.

2. Heat dissipation due to microvibrations in low temperature experiments
University essay from KTH/FysikAbstract : Ultra-sensitive photodetectors on-board space missions need very low temperatures to keep a good resolution. Cryo-coolers, such as pulse-tubes, help maintaining these conditions within a cryostat. In return however, they generate micro-vibrations. READ MORE

3. Development of Inlet Valve in an Oil-free Novel Steam Engine
University essay from KTH/Maskinkonstruktion (Inst.)Abstract : A novel compact steam engine design could be used to replace current combustion engines in the rapidly changing world of renewable energy. Especially with the increased research into alternative fuels such as hydrogen fuel cells and methane, which would vastly improve the efficiency of a steam engine. READ MORE

4. Polycapillary X-Ray Optics for Liquid-Metal-Jet X-Ray Tubes
University essay from Uppsala universitet/MaterialfysikAbstract : Investigating and mapping fundamental processes in nature is a driving force for breakthroughs in research and technology. Doing so, requires knowledge of the smallest scales of the world. One way of performing measurements on these scales is through intense x-ray sources, which have improved greatly over the last decades. READ MORE
