1. Designing multicomponent alloy coatings for corrosion protection
Abstract : This thesis explores the design of metallic coatings for corrosion protection. The subject of the study was the new class of materials multicomponent alloys (MCAs, also known as high entropy alloys). They consist of near-equal concentrations of many (four or more) metals and are often reported to form a single phase with a simple crystal structure. READ MORE

2. Thermal Barrier Coatings : Durability Assessment and Life Prediction
Abstract : Thermal barrier coating (TBC) systems are coating systems containing a metallic bond coat and a ceramic top coat. TBCs are used in gas turbines for thermal insulation and oxidation resistance. READ MORE

3. Multilayer Structures for Biomaterial Applications : Biomacromolecule-based Coatings
Abstract : The cellular response to a biomaterial, such as a dental implant, is mainly governed by the surface properties, and can thus be altered by the introduction of a surface coating. In this thesis the buildup of a biomacromolecule-based coating formed by layerby-layer (LbL) deposition of the charged polypeptides poly(L-lysine) (PLL) and poly(L-glutamic acid) (PGA) has been studied.

4. Reaching Kinetic Selectivities : In Pursuing Novel Ternary Oxide Coatings, and Beyond
Abstract : Kinetically driven synthesis pathways have the potential to allow new ways to develop materials and phases with much-improved properties. This particularly concerns metastable and multicomponent phases that require a selective kinetic targeting during the synthesis to circumvent the formation of thermodynamically stable products.

5. Surface coatings as xenon diffusion barriers on plastic scintillators : Improving Nuclear-Test-Ban Treaty verification
Abstract : This thesis investigates the ability of transparent surface coatings to reduce xenon diffusion into plastic scintillators. The motivation for the work is improved radioxenon monitoring equipment, used with in the framework of the verification regime of the Comprehensive Nuclear-Test-Ban Treaty. READ MORE
