2. Synthesis and modification of monodisperse polymer particles for chromatography
Abstract : Liquid chromatography is an analytical technique that is constantly facing new challenges in the separation of small molecules and large biomacromolecules. Recently the development of ultra high pressure liquid chromatography has increased the demand on sturdy particles as stationary phase. READ MORE

3. Thiol-Ene/Yne Adhesives for Tissue Fixation
Abstract : The utilization of adhesives in surgery has not reached its full potential and research in the field is encouraged by the surgeons’ desire for improved alternatives to today’s tissue fixation strategies. Here, adhesive resins based on thiol-ene coupling (TEC) chemistry or thiol-yne coupling (TYC) chemistry are exploited to develop tissue adhesives that cure fast and on-demand via photoinitiation.

4. Photocuring of multifunctional monomers initiated by camphorquinone / amine systems for application in dental restorative resins
Abstract : This thesis deals with the photopolymerization of mono-, di- and trifunctional monomers initiated by carnphorquinone (CQ) alone and/or with different amines (AMH) as coinitiators in air as well in nitrogen. The kinetics of photopolymerization was measured by photoisothermal calorimetry (photo-DSC), which allowed the measurement of the rate of polymerization (Rp), maximum rate of polymerization (Rpmax), time of inhibition (tinh), time at which Rpmax was obtained (tmax), double bond conversion (p) and maximum double bond conversion (pmax).
