Capture of Carbon Dioxide in Lamellar Phase Liquid Crystals
(Master thesis, 2018)One of the most important environmental concerns the earth faces today is the release of greenhouse gases and other gases that accumulate in the atmosphere. Among these gases, carbon dioxide is one of the most abundant ... -
Capturing CO2 by ionic liquids and deep eutectic solvents: A comparative study based on multi-level absorbent screening
(Peer reviewed; Journal article, 2023)Because of the high energy consumption and volatility of organic amine solvents in conventional CO2 capture processes, ionic liquids (ILs) and deep eutectic solvents (DESs) have been widely expected as alternative CO2 ... -
Capturing metal-support interactions in situ during the reduction of a Re promoted Co/γ-Al2O3 catalyst
(Journal article; Peer reviewed, 2016)The reduction of a Re promoted Co/γ-Al2O3 catalyst was monitored in situ by synchrotron X-ray powder diffraction (XRPD) under H2 environment. Whole powder pattern analysis revealed a non-linear expansion of the unit cell ... -
Carbon Based Coatings for Metallic Bipolar Plates in PEM Fuel Cells
(Master thesis, 2013)Global warming and the climate changes are issues that concern everyone. The transition to other energy carriers than fossil fuels is a key barrier if we are to reduce our dependence on oil. Hydrogen is forecasted as the ... -
