1. Skådepenningar i enväldets tjänst: Ekonomisk och politisk legitimitet i Gustav III:s kungliga medaljer 1772–1792
Kandidat-uppsats, Lunds universitet/Historisk arkeologiSammanfattning : This bachelor’s thesis in Historical Archaeology concerns how the royal medals of the Swedish King Gustav III (1756-1792) functioned as a means of political propaganda, namely in what ways an official legitimizing narrative was created about the country’s economy and the role of the King herein, through the images and texts of the royal medals. Inspired by Clifford Geertz’ anthropological perspective on authority it views the royal medal as a means of communication and as a branch of a greater “master fiction” that monarchy created around itself.

2. Gas Chromatographic Method Development for Analysis of Samples from a Carbon Capture Pilot Plant
Master-uppsats, Lunds universitet/Kemiteknik (CI)Sammanfattning : In response to the escalating threat of climate change, carbon capture and storage have gained increasing attention as an important component in mitigating the global carbon dioxide emissions. Substantial research efforts have focused on enhancing the energy efficiency and availability of these technologies. LÄS MER
3. The active phase of Pt(110) during catalytic CO oxidation
Master-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionenSammanfattning : CO oxidation is an important topic in heterogeneous catalysis, due to its role in industrial processes such as pollution reduction in the auto industry, and ethanol or other fuel production. In the automotive catalytic converters CO oxidation reduces the poisonous CO to CO2 by reacting with O2. LÄS MER
4. Stability improvement to a ruthenium catalyst for partial oxidation of methane
Master-uppsats, Lunds universitet/Kemiteknik (CI)Sammanfattning : Catalytic partial oxidation of methane (CPOM) is an energy-efficient alternative to steam reforming, the currently prevailing method for energy production from natural gas. Hulteberg Chemistry & Engineering AB has developed a catalyst for the partial oxidation of methane into syngas, for use in solid oxide fuel cells. LÄS MER
5. Ion pair chromatography of carboxylic and sulfonic acids with trialkylamines : An investigation of the relationship between the adsorption isotherm of the IPR and the retention factor of the analyte
Kandidat-uppsats, Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)Sammanfattning : Ion pair chromatography has found many uses within analytical chemistry and understanding of the chromatographic process with an ion-pairing reagent have been studied since the 1970s. The adsorption of the Ion-pairing reagent to the stationary phase is understood to be important and many studies have been dedicated to looking at the adsorption isotherms of the earlier quaternary alkylammonium ions.
