A brighter light on gold integration in silver nanoclusters
(2016)Bimetallic Ag29-xAuxLA12 clusters were successfully synthesized. A strong preference was seen for the monodoped Ag28Au cluster. The bimetallic clusters showed a two- to threefold increase in luminescence, so that the quantum ... -
A stereo-tweezer for ultracold atoms
(2014)The Atom Plasmonics group plans to study the interactions between Rubidium atoms in the near-field of nanostructures. For these experiments an optical tweezer is needed to move the trapped atoms above a gold surface. To ... -
A study on the synthesis of a model CoMnO catalyst for FTO reactions
(2016)In this work, the synthesis of a model CoMnO catalyst is described. MnO was used in large amounts (up to 80 wt%) to enhance the lower olefin selectivity of cobalt. The lower olefin selectivity promotion by MnO was probed ... -
Acceptorless Catalytic Alcohol Dehydrogenation and Depolymerization Applied to Lignin
(2018)A new catalytic method for the selective depolymerization of lignin via acceptorless dehydrogenation has been developed. Initially, using a Cp*-iridium bipyridonate catalyst under basic conditions, primary alcohol ... -
Active terahertz beam steering using photo-excited thin-?film semiconductors: Changing the transmission directionality by optically inducing blazed refractive index gratings in gallium arsenide
(2014)Changing the directionality of electromagnetic radiation has gained much attention from both industry and the research community in the last century. In the infrared and terahertz regime beam steering is conventionally ... -
Aggregation behavior of snowman-like particles with oppositely charged large microspheres and polymers
(2017)Recently Evers et al. [1] have shown that snowman particles assemble into hollow virus-like capsules in the absence of template. In this thesis I will show the aggregation behavior of the snowman particles in the presence ... -
Alpha-Arylation of Acetophenones via a Radical Mechanism
(2016)Alpha-arylation is an important reaction which is commonly used in the synthesis of many pharmaceuticals. To catalyze these reactions palladium catalysts are usually used, however copper and nickel also can be used. ... -
Analysis of STED Doughnuts generated by a Spatial Light Modulator
(2015)This paper summarizes the research done for a master thesis at the Molecular Biophysics group, part the of the Physics Department of Utrecht University. Using a custom microscope set- up, we have researched ... -
Applicability of Laser-Induced Desorption Quadruple Mass Spectrometry (LID-QMS) for the Determination of Local Deuterium Retention
(2013)Laser-induced desorption quadruple mass spectrometry (LID-QMS) is under development in the target exchange and analysis chamber of MAGNUM-PSI. Research to the applicability of LID-QMS as a diagnostic to determine local ... -
Atomically Coherent Nanocrystal Superlattices
(2013)Many applications have been envisioned for supercrystals of quantum dots (QDs), ranging from solar cells to LEDs. The properties of such systems depend on the properties of the constituent particles, but also on the structure ... -
Catalytic Degradation of Organic Molecules by Colloidal Hematite in a Silica Box via Fenton-like Reaction
(2013)Fenton's reagent is the combination of ferrous ions and hydrogen peroxide and is commonly used for the degradation of organic molecules. The ferrous ions promote the formation of radicals from the hydrogen peroxide which ...
