6. Colloidal zeolites : from nucleation to zoned films by seeded growth
Sammanfattning : The work presented in this thesis concerns the investigation of nucleation kinetics for colloidal zeolites, especially the determination of the nucleation period during crystallization. It also concerns the use of colloidal TPA-silicalite-1 for the preparation of zoned MFI films. LÄS MER
7. Synthesis of ZnO and transition metals doped ZnO nanostructures, their characterization and sensing applications
Sammanfattning : Nanotechnology is a technology of the design and the applications of nanoscale materials with their fundamentally new properties and functions. Nanosensor devices based on nanomaterials provide very fast response, low-cost, long-life time, easy to use for unskilled users, and provide high-efficiency. LÄS MER
8. Fundamental deactivation mechanisms of Fe-BEA as NH3-SCR catalyst - Experimental studies and kinetic modeling
Sammanfattning : Due to globalization and an increasing transport sector the interest for more fuel efficient combustion engines operating under lean conditions has increased. The products formed during the burning process in internal combustion engines are major contributants to global air pollution, where carbon monoxide (CO), hydrocarbons (HC) and nitrogen oxides (NOX) are the major toxic components regulated in many countries.

9. Modification of zeolites and synthesis of SAPO-templated carbon
Sammanfattning : Zeolites are crystalline aluminosilicates with diverse structures and uniform porosities. They are widely used as catalysts, adsorbents and ion-exchangers in industry. Direct or post modifications optimize the performance of zeolites for different applications. In this thesis, IZM-2 and TON-type zeolites were synthesized, modified and studied. LÄS MER
10. Unlocking the Potential of Brewer’s Spent Grain : Sustainable Biorefinery Approach and Value-Added Product Generation
Sammanfattning : Brewer’s spent grain (BSG) constitutes 85% of brewing byproducts and 30% of initial malt. In 2021, BSG production reached approximately 37.2 million tons. Owing to its high moisture and nutritional content, BSG is prone to biological deterioration, causing environmental issues when discarded as waste. LÄS MER
