1. Breaking the symmetry: creation and transfer of optical activity via total spontaneous resolution and stereoselective reactions
Abstract : The generation of optical activity from achiral or racemic precursors – absolute asymmetric synthesis – is discussed in relation to the origin of biomolecular homochirality but is also often (incorrectly) regarded as being impossible. One approach to absolute asymmetric synthesis is the use of compounds that form chiral crystals. READ MORE

2. Plasmonics with a Twist
Abstract : This thesis focuses on the exploration of interactions between circularly polarized light and plasmonic nanostructures, and nanoparticles. Polarization is an integral part of light and has a wealth of applications in the modern world. READ MORE

3. Transition Metal-Mediated Selective Functionalizations of Bio-Derived Building Blocks
Abstract : In order to transition to a more sustainable chemical industry, it is necessary to replace the fossil starting materials that are largely used today with renewable ones. Starting materials available from abundant natural sources, or which can be efficiently produced via a biotransformation, are of high interest in this regard. READ MORE

4. Tailored Properties of Ferromagnetic Thin Films
Abstract : Magnetic thin films and patterned nanostructures have been studied with respect to their magnetic properties using SQUID-magnetometry, magnetic force microscopy, electrical measurements, and micromagnetic calculations. Properties of vortex domain walls, trapped in Permalloy nanowires with artificial constrictions, were investigated experimentally and by numerical calculations. READ MORE

5. Synthesis and Applications of P-Chirogenic and Axially Chiral P,N-Phosphines as Ligands and Organocatalyst
Abstract : This thesis deals with the enantioselective synthesis of chiral mixed phosphorous/nitrogen compounds and some of their applications in asymmetric synthesis. For the most part, the compounds are P-chirogenic, with the chirality centered on the phosphorous atom. The last part of the thesis deals with axially chiral phosphoramidites. READ MORE
