1. Application of Fourier Transforms to time-resolved ambient pressure spectroscopy operando studies of CO oxidation over Pt(111)
University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/SynkrotronljusfysikAbstract : The study of heterogeneous catalysis has important implications in increasing the efficiency of industrial processes and in reducing the emissions of greenhouse gases from sources such as automobiles. A reaction with high industrial relevance is the oxidation of CO on noble metal catalysts. READ MORE

2. Finding new members of the VelHel-4 stream
University essay from KTH/Skolan för teknikvetenskap (SCI)Abstract : According to the paradigm of lambda-CDM cosmology, the stellar halo ofour Galaxy has been built-up over time through the accretion of other galaxiesand star clusters. The remnants of some of these are still observable today asstellar streams, but are typically very faint and difficult to resolve amidst the farmore numerous foreground Milky Way stars. READ MORE

3. A Quantum Chemical Investigation of Chemical Vapour Deposition of Fe using Ferrocene and Plasma Electrons
University essay from Linköpings universitet/KemiAbstract : Thin films provide a remarkable asset, as depositing a thin surface layer can completely alter a material’s characteristics and provide new, inexpensive, and valuable properties. In 2020, a new Chemical Vapour Deposition (CVD) approach was developed at Linköping University, using plasma electrons as reducing agents for the deposition of metallic thin films. READ MORE

4. Photocatalytic generation of hydrogen from cellulose
University essay from KTH/Kraft- och värmeteknologiAbstract : Uncontrolled emission of greenhouse gases caused by consumption of fossil fuels has led to the urgent need to develop low-emitting energy technologies such as those exploiting renewable energies. In this context, hydrogen (H2) represents an opportunity to enhance the development of such technologies, in light of the possibility to use it as an energy storage for non-programmable renewables, and for its potential to decarbonize key emitting sectors such as transport sector.

5. Quantum chemical studies of the reactivity of gold nanoparticles towards molecular radicals
University essay from KTH/KemiAbstract : Kvantkemiska studier av reaktiviteten hos guldnanopartiklar Au3-Au11 och Au13 mot O- centrerade molekylradikaler OH , OOH , OCH3 och H2O undersöks. Olika molekylära ytegenskaper tas med i beräkningen, elektrostatiska ytpotentialen, den genomsnittliga lokala joniseringsenergin, electron attachment energy och spinndensiteten (VS(r), IS(r), TS(r), ES(r) och S(r)).
