1. Thermal barrier coatings for diesel engines
Sammanfattning : The upward trend in internal combustion engine efficiency is driven by the demands for emission reduction and fossil fuel depletion. No present alternative fuel can produce energy comparable to that produced by conventional oil; this necessitates the reasonable, efficient usage of oil. LÄS MER
2. Thermal history of the Phanerozoic sedimentary succession of Skåne, southern Sweden, and implications for applied geology
Sammanfattning : Post-depositional thermal conditions have been investigated throughout the Phanerozoic sedimentary succession in Skåne. Clay mineralogy and illite crystallinity have been the main tools for the Lower Palaeozoic strata. Within the Mesozoic sequence thermal influence was examined using RockEval pyrolysis and vitrinite reflectance analysis. LÄS MER
3. Influence of surface roughness on rolling contact fatigue considering thermal elastohydrodynamic lubrication effects : Due to Corona it is not possible to attend this defense in person, instead attend via this link: https://play.kth.se/media/0_omfsppe6
Sammanfattning : Rolling contacts are utilized in many technical applications, both in bearings and in the contacts between gear teeth. These components are subjected to high loads in many of their applications. The high loads causes very high contact pressures which may cause rolling contact fatigue, often denoted as pitting or spalling. LÄS MER
4. Conversion of Biomass to Renewable Liquid Feedstocks in Pyrolysis-based Applications
Sammanfattning : The production of chemicals and fuels currently rely on fossil resources which are associated with global warming as well as economic and political instabilities. The demand for renewable alternatives is increasing as legislations on greenhouse gas emissions are becoming more stringent. LÄS MER
5. Biophysical Studies of Apolipoprotein A-IM and a Partitioning study
Sammanfattning : The major part of this thesis deals with the similarities and differences in some biophysical properties of apolipoprotein A-I (apo A-I) and the molecular variant apolipoprotein A-IMilano (apo A-IM), and the influence on lipid binding. A model compound partitioning study has also been performed. LÄS MER
