2. Femtosecond Laser Microfabrication of Glasses and 2D Materials for Photonics and Energy Storage
Sammanfattning : Femtosecond laser-based fabrication technologies have seen rapid developments in the past decades, thanks to the capability of femtosecond lasers to induce localized multiphoton absorption in materials. Multiphoton absorption can result in various material modifications that can be leveraged for additive and subtractive manufacturing. LÄS MER
3. NH3-SCR chemistry for NOx abatement: Influence of zeolite support on N2O formation & phosphorus species addition
Sammanfattning : Different lattice arrangements of Si, Al, and O atoms result in a variety of pore dimensions and zeolite channel network systems, giving rise to different physicochemical environments inside the catalyst cage. The objective of the thesis work was to understand the influence of zeolite topology on NH3-assisted SCR chemistry over CHA, MFI, and BEA frameworks, on the formation of N2O and the addition of phosphorus species to attain fundamental insight into NOx emission control.

4. The Value of Values : A Critical Assessment of Citizenship by Investment Programs in the European Union
Sammanfattning : The primary objective of this doctoral dissertation is to thoroughly examine the phenomenon of citizenship by investment programs (CIPs) by analyzing the existing programs within the European Union (EU) as of 2018. Additionally, I aim to provide a critical legal assessment of these programs, which can be instrumental in evaluating potential future initiatives. LÄS MER
5. Mesoporous material systems for catalysis and drug delivery
Sammanfattning : Hybrid material systems possess multi-functional properties which make them intriguing for the materials science community since very early dates. However, it is not straightforward to produce such material systems. A smart and efficient approach is necessary to extract the desired properties of each component under the desired conditions.
