1. Dynamical Analysis of Chemical Activity of Sterically Encumbered Lewis acid/base Pairs
Abstract : This licentiate thesis is about the dynamics analysis of chemical reactions involving a stoichiometric mixture of sterically hindered Lewis base (LB) and Lewis acid (LA) – the so-called frustrated Lewis pairs (FLPs). The tool for dynamical description of chemical reactions is the ab initio molecular dynamics (AIMD) simulations together with the calculation of minimum energy paths (MEPs) on the potential energy surfaces (PESs).

2. Direct Catalytic Nucleophilic Substitution of Non-Derivatized Alcohols
Abstract : This thesis focuses on the development of methods for the activation of the hydroxyl group in non-derivatized alcohols in substitution reactions. The thesis is divided into two parts, describing three different catalytic systems. READ MORE

3. Aspects on wettability and surface composition of modified wood
Abstract : Wood is often combined with other materials such as thermoplastics, adhesives and coatings. In general, combinations of wood and polymers especially in outdoor exposure have poor long-term durability. READ MORE

4. Terminating species and Lewis acid-base preference in oxohalides – a new route to low-dimensional compounds
Abstract : This thesis is based upon synthesis and structure determination of new transition metal oxo-halide compounds, which includes p-element cations that have a stereochemically active lone pair. A synthesis concept has been developed, which uses several different structural features to increase the possibility to yield a low-dimensional arrangement of transition metal cations. READ MORE

5. Filler Controlled Morphology in Polymer Blends
Abstract : The morphology of a polymer blend can be altered very dramatically when a filler is added. Depending on the mutual interactions of the polymers and their individual interactions with the filler, many different filler distributions are possible. READ MORE
