1. Gas Chromatography Mass Spectrometry Analysis of Epoxides in Gas Phase Reactions
University essay from KTH/KemiAbstract : En nyligen genomförd studie visade att reaktioner mellan vissa radikaler och omättade alkener är snabbare vid rumstemperatur än vad man tidigare har trott. Dessa reaktioner är viktiga för atmosfäriska oxidationscykler och följaktligen var syftet med detta masterprojekt att beräkna hastighetskonstanterna för dessa reaktioner mellan metyljodid och 1-jodidpentan med tetrametyletylen, isopren och limonen vid rumstemperatur genom att kvantifiera respektive epoxid; tetrametyloxiran, isoprenmonoxid och limonen 1,2 epoxid, som producerades.

2. Electrochemical oxidation of PFAS in soil conditions : Using Boron-doped diamond electrodes and iron electrodes
University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserAbstract : Per- and polyfluoroalkyl substances (PFAS) are a rising topic in the field of contaminated sites around the world, with destruction of these being an area in dire need of innovation. Previous experiments of destructive character have been proven efficient using boron doped diamond electrodes (BDD) in small scale electrochemical cells. READ MORE

3. Unspecific interactions in different batch variations of agarose based base matrices at different NaCl concentrations.
University essay from Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)Abstract : Size exclusion chromatography (SEC) separates molecules based on their actual size rather than their molecular weight. This indicates that the smaller a molecule is, the longer it will be held in the column since it can penetrate the pores more effectively than a bigger molecule, resulting in a longer retention time, whereas the larger molecule has a shorter retention time.

4. Orbit-simulator for downstream processes
University essay from Lunds universitet/Kemiteknik (CI)Abstract : In an ever more digitilized society, the transition is palpable also in the pharmaceutical industry. The control system Orbit was developed at the department of chemical engineering at Lund University, to be able to automate downstream processes based on the ÄKTA-system. READ MORE

5. As I live and breathe! : The effects of hypolimnic oxygenation on benthic macroinvertebrate and zooplankton assemblages
University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskapAbstract : Exacerbated deep-water hypoxia, brought about by anthropogenic-derived dissolved organic carbon (DOC) input, has potentially detrimental impacts on organisms residing in freshwater ecosystems. Oxygenation of the water column is a potential management strategy to mitigate this impact, and used to alleviate DOC induced oxygen depletion. READ MORE
