1. Tracing Tempera through Time-of-Flight Secondary Ion Mass Spectrometry Analysing samples from four icons from the Nationalmuseum collection
University essay from Göteborgs universitet/Institutionen för kulturvårdAbstract : This thesis will analyze samples in form of cross-sections taken from four icons of the Nationalmuseum collection, two Russian, from the 18th and 19th centuries and two Greek, also from the 18th and 19th centuries, using the Time-of-Flight Secondary Ion Mass Technique. The objective is to detect, isolate and, if possible, identify the amino acids and the fatty acids in the protein and lipids used in the tempera, the ground, and the olifa using Time of Flight Secondary Ion Mass Spectrometry.

2. Synthesis of aromatic thiol ligands for the formation of thermoelectric materials
University essay from KTH/KemiAbstract : I detta arbete så har en uppsättning aromatiska ditiol-ligander framställts (3,5-dimerkaptobensoesyra I, methyl-3,5-dimerkaptobensoat II, 3,5-dimerkaptotoluen III, 4,6-dimerkaptoisoftalaldehyde IV). En trestegssyntes innehållande Newman-Kwart omlagring som nyckelsteg användes för framställning av föreningarna I-III medan förening IV togs fram via en annan syntesväg. READ MORE

3. In-Situ Investigation of Particle Assisted GaSb Nucleation Using Environmental TEM
University essay from Lunds universitet/Centrum för analys och syntesAbstract : III-V semiconductor material based nanowires have been extensively studied and shown to be a very exciting building block for future electronics. Material systems such as GaSb show a lot of promise in optoelectric and thermoelectric generation applications because of its high electron mobility and small bandgap. READ MORE

5. Investigation of Antenna Radomes in Low Earth Orbits
University essay from Lunds universitet/Centrum för analys och syntesAbstract : Introduction: This master’s thesis focuses on exploring improved alternative material solutions for antenna radomes used to protect Beyond Gravity Sweden’s satellite antennas in low Earth orbits. Background: As the environment in low Earth orbit is harsh, surface materials on satellites experience high levels of atomic oxygen, ultra violet radiation, thermal-fluctuation, charged particles and micro meteoroids.
