1. Tracing Tempera through Time-of-Flight Secondary Ion Mass Spectrometry Analysing samples from four icons from the Nationalmuseum collection
Master-uppsats, Göteborgs universitet/Institutionen för kulturvårdSammanfattning : 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
Master-uppsats, KTH/KemiSammanfattning : 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. LÄS MER
3. Leveraging CNN for Automated Peak Picking in Untargeted Metabolomics without Parameter Dependencies
Master-uppsats, Göteborgs universitet/Institutionen för data- och informationsteknikSammanfattning : Metabolomics is a scientific discipline that involves the thorough analysis of small molecules, known as metabolites, found within a biological system. Furthermore, liquid chromatography-mass spectrometry (LC-MS) is a commonly used analytical technique in metabolomics for analysing biological samples due to its broad coverage of the measurable metabolome.

4. Creating a High-Throughput Workflow for Automated Peptide Characterization using LC-MS
Master-uppsats, Lunds universitet/Centrum för analys och syntesSammanfattning : In the early stage of a drug discovery project, there is a need for efficient methods that can analyse peptides in short time. This includes methods that confirm the peptide’s identity and estimates its relative purity in an efficient and reliable way. LÄS MER
5. Qualitative Analysis of Chlorinated Paraffins in Recycled Plastics
Kandidat-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknikSammanfattning : Described in many studies as dangerous for the environment and potentially carcinogenic for humans, Chlorinated Paraffins (CPs) are easily widespread due to their substantial production and use in different products. Previous studies reported the presence of CPs in different plastic polymers. LÄS MER
