21. Study of novel electronic materials by mid-infrared and terahertz optical Hall effect
Sammanfattning : Development of silicon based electronics have revolutionized our every day life during the last three decades. Nowadays Si based devices operate close to their theoretical limits that is becoming a bottleneck for further progress. LÄS MER
22. Bottom-up Fabrication of Functional DNA Nanostructures
Sammanfattning : This thesis demonstrates bottom-up fabrication of a fully addressable non-repetitive network on the nanometer scale, assembled by synthetic DNA molecules. Each side constitutes a unique sequence of 10 bases, i.e. 3. LÄS MER
23. Synthesis, characterization and applications of hierarchical porous inorganic materials: a multi-dimensional approach
Sammanfattning : Zeolites are a type of microporous crystalline materials that have been widely used in industrial applications including separation, adsorption, and catalysis. However, great limitations on diffusion through these materials can arise due to the small pores present in mircoporous frameworks, and this can impact catalytic reactions in particular. LÄS MER
24. Effects of Varying Combustion Conditions on PCDD/F Formation
Sammanfattning : Polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) are by-products emitted from combustion sources such as municipal solid waste (MSW) incineration plants. These organic compounds are recognized as toxic, bioaccumulative and persistent in the environment. LÄS MER
25. Enhanced boiling heat transfer from a novel nanodendritic micro-porous copper structure
Sammanfattning : Following licentiate thesis is a summary of the advances made within the research project - Micro- and nano structured surfaces for enhanced boiling heat transfer – which is a collaboration effort between the Divi-sion of Applied Thermodynamics and Refrigeration and the Division of Materials Chemistry at the Royal Institute of Technology (KTH). The main objectives with this research project has been to: develop methods for producing highly efficient boiling surfaces with well defined micro- and nano-structured porous surfaces by the use of micro- and nano-manufacturing techniques.
