1. Enhancing UV-protection of clear coated wood by utilizing reactive UV-absorber and epoxyfunctionalized soybean oil
Abstract : This work presents the development of a new pretreatment for clear coated wood, that aims to increase the photoprotection of exterior wood products, and at the same time make the system more environmentally friendly. The pretreatment comprises the reactive UV absorber 2-hydroxy-4(2,3-epoxypropoxy)-benzophenone (HEPBP), which has a primary epoxy group that can be covalently attached to the hydroxyl groups of the wood substrate.

2. Enhancing UV protection of clear coated exterior wood by reactive UV absorber and epoxy functional vegetable oil
Abstract : Since ancient times wood has played a large role in human activities, both in terms of fuel and for construction purposes. A drawback with wood in exterior applications is, however, its susceptibility to photo-initiated degradation, caused by radiation from the sun. READ MORE

3. Reflective structural colors and their actuation using electroactive conducting polymers
Abstract : The integration of inorganic photonic nanostructures with organic materials opens new possibilities to dynamically modify the optical response of photonic devices. This thesis focuses on how to generate efficient reflective structural colors and tune them in combination with a conducting polymer (CP). READ MORE

4. ALD Buffer Layer Growth and Interface Formation on Cu(In,Ga)Se2 Solar Cell Absorbers
Abstract : Cu(In,Ga)Se2 (CIGS) thin film solar cells contain a thin layer of CdS. To avoid toxic heavy-metal-containing waste in the module production the development of a cadmium-free buffer layer is desirable. This thesis considers alternative Cd-free buffer materials deposited by Atomic Layer Deposition (ALD). READ MORE

5. Interstellar absorption across the electromagnetic spectrum
Abstract : We report results of a multi-wavelength study of interstellar absorption in diffuse molecular clouds that lie in the direction of flat-spectrum quasars. Quasars as back-ground sources allow the measurement of Galactic interstellar absorption across the electromagnetic spectrum from mm to X-ray wavelengths. READ MORE
