1. Bläckborttagning från ben med hjälp av geler En kvantitativ studie för bläckborttagning på björnbäcken och björnkranium från Naturhistoriska riksmuseet
Kandidat-uppsats, Göteborgs universitet/Institutionen för kulturvårdSammanfattning : This bachelor's thesis has investigated four different hydrogels loaded in different solvents efficiency to remove unknown ink from four pelvic bones and one skull from five bear individuals that belongs to The Swedish Museum of Natural History. The experimental part of the thesis consists of an FTIR analysis together with microscopy and macroscopy analysis of the ink on the bear skeletons, as well as some tests of different gel-solvent combinations on a moose skull.

2. Analysis of fatty acids in fatty acid-based herbicides by gas chromatography
Master-uppsats, Lunds universitet/Kemiska institutionenSammanfattning : Fatty acids-based herbicides are considered to be a green alternative to synthesized weed control products. However, the environmentally sustainable effect of those herbicides needs more investigation to be confirmed. LÄS MER
3. The impact of human relevant mixture of contaminants on the development of human adipocytes
Uppsats för yrkesexamina på grundnivå, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)Sammanfattning : The objective of this project was to investigate how organic anthropogenic chemicals (OCs) effect the differentiation of adipocytes in the human body. The objective is also to contribute to novel research in how groups of chemicals in our surrounding affect us. LÄS MER
4. Investigation into methods for N-trifluoromethylation of a key intermediate in the synthesis of an SGLT1 inhibitor and potential starting point for anti-diabetes drugs
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Preparativ läkemedelskemiSammanfattning : Sodium-glucose transporters (SGLTs) are a group of membrane proteins involved in regulating blood-glucose levels. Compounds which inhibit SGLTs are therefore of interest in the development of new treatments for diabetes. LÄS MER
5. Chemical analysis of polycyclic aromatic compounds in plastic materials used in indoor environments
Uppsats för yrkesexamina på grundnivå, Örebro universitet/Institutionen för naturvetenskap och teknikSammanfattning : Human bodies are in constant interaction with materials containing known and unknown chemicals of hazardous behavior. One group of chemicals are polycyclic aromatic compounds (PACs) which can be present in both indoor and outdoor materials, commonly in plastics. LÄS MER
