1. Analysis of polyfunctional thiols in beer : Developing a novel method of extraction and analysis using GC-FID
University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)Abstract : In this project, attempts were made to identify and quantify two polyfunctional thiols – 4-mercapto-4-methyl-pentanone and 3-mercaptohexyl acetate – and three monoterpene alcohols – linalool, geraniol, and β-citronellol – in beer samples. In order to avoid the use of hazardous compounds such as dichloromethane and hydroxymercuriobenzoate, common in traditional methods, two novel techniques were tested: a pure liquid-liquid extraction of the beer samples with cyclohexane, and a liquid-liquid extraction with cyclohexane followed by solid phase extraction on silver ion columns.

2. Inhibited surface-thiols in Geobacter sulfurreducens : Mercury uptake and methylation rates
University essay from Umeå universitet/Kemiska institutionenAbstract : Due to daily human (anthropogenic) industrial activity, a lot of elemental mercury (Hg0) has been released to the atmosphere. The mercury can then spread globally, since mercury has the ability to remain atmospheric for up to a year. When mercury deposits, it can end up in anaerobic environments such as sediments and soil.

3. HgII uptake in Geobacter sulfurreducens spheroplasts : Thiols’ role in Hg partitioning and methylation
University essay from Umeå universitet/Kemiska institutionenAbstract : Mercury (Hg) is a naturally occurring trace element and pollutant that is ubiquitous in aquatic ecosystems. All Hg species are hazardous, but methylmercury (MeHg) is the most alarming due to its neurotoxicity, teratogenicity, and bioaccumulation in the food web. READ MORE

4. Structural Battery Electrolytes
University essay from KTH/Fiber- och polymerteknologiAbstract : Strukturella batterier är multifunktionella; de tillhandahåller lagring av elektrokemisk energi samtidigt som de bidrar med en lastbärande funktion. Tillsammans möjliggör detta att batteriet kan integreras i karossen hos ett elektriskt fordon eller apparat. READ MORE
