11. Modification of microcapsules for controlled release
Sammanfattning : Fouling of marine organisms such as algae and barnacles on the boat hull is an enormous problem for the shipping industry. The negative consequences for the society are both economical and environmental. To prevent fouling in general, biocides are typically incorporated directly into the paint. LÄS MER
12. Novel electrode and photoelectrode materials for hydrogen production based on molecular catalysts
Sammanfattning : The PhD project focussed on the application of a cobalt tetraazamacrocyclic complex, in the literature commonly referred to as [Co(CR)Cl2]+ as a molecular catalyst for the hydrogen evolution reaction (HER). This was within the broader scope of the EU MSCA H2020 ITN ‘eSCALED’ project, which primarily aimed to create artificial leaf devices for the storage of solar energy in chemical fuels and, as part of this, sought the development of novel bio-inspired and scalable materials.

13. Photophysics of Perovskite Nano- and Microcrystals
Sammanfattning : The demand and consumption of energy is increasing dramatically all around the world. Broad adoption of fossil fuels has triggered an enormous threat to the environment. To ensure sustainability of our species and habitat, new solutions to fulfill the energy demand have to be found. LÄS MER
14. Local structure and dynamics in proton conducting perovskite oxides: insights from quasielastic neutron scattering and infrared spectroscopy
Sammanfattning : Proton conducting oxides have been extensively studied in the past decade due to their potential application in a number of energy related devices such as solid oxide fuel cells, hydrogen sensors, and steam electrolyzers. However, the final industrialisation of these materials depends on unlocking fundamental questions about the relationship between their atomic structure, localized proton dynamics and proton conductivity.

15. Crystallization of Parabens : Thermodynamics, Nucleation and Processing
Sammanfattning : In this work, the solubility of butyl paraben in 7 pure solvents and in 5 different ethanol-water mixtures has been determined from 1 ˚C to 50 ˚C. The solubility of ethyl paraben and propyl paraben in various solvents has been determined at 10 ˚C. LÄS MER
