1. Acoustic, Thermal and Non-thermal Dynamics in Condensed Matter Studied by Time-Resolved X-ray Diffraction
Sammanfattning : The method of using short laser and X-ray pulses to investigate dynamics in materials (pump-probe) has been used for several decades. This thesis presents work that was carried out using these sources of light to reveal acoustic, thermal and non-thermal dynamics. LÄS MER
2. Ionization of large molecules with short laser pulses
Sammanfattning : The decay dynamics of fullerenes and polyaromatic hydrocarbons (PAH) after femtosecond-laser excitation have been studied experimentally by electron momentum mapping and mass spectrometry. The electron spectra of fullerenes and large PAH-molecules were found to be exponentially decreasing with energy without any distinct peaks outside the photon energy. LÄS MER
3. Preheating of ambient air by a system of earth tubes as a heat source for buildings
Sammanfattning : .... LÄS MER
4. The development of novel foods from Swedish pulses : Raw material composition and processing effects
Sammanfattning : A gradual shift towards a healthier and more sustainable diet with a higher quantity of plant-based products is suggested to be one of the most efficient ways to alleviate environmental pressure from the current food system. Pulses could play a crucial role in this shift due to the multi-faceted benefits they have on the environment and human health. LÄS MER
5. High Power, Long Wavelength Semiconductor Disk Lasers for Continuous and Mode-Locked Operation
Sammanfattning : The semiconductor disk laser has recentlyemerged as an attractive alternative to bulky and power consuming gas and solid state lasers. It offers compact, powerful and efficient devices with W level output power and beam properties earlier not achieved with semiconductor lasers. LÄS MER
