Organic Electrolytes for Thermoelectric Devices and CNT Electrode functionalization by Nitrogen-doping
(Master thesis, 2012)In this thesis a thermoelectric cell is developed. Aligned Carbon Nanotubes and aligned Nitrogen-doped Carbon Nanotubes are used as electrode materials. Ferri/Ferrocyanide and Tetrabutylammonium Nitrate (TBAN) electrolytes have ... -
Photochemistry of a Nucleobase Relevant to the Formation of Malignant Melanoma - Using Spectroscopic Techniques to Study the UV-Induced Damage of Thymine on MoS2
(Master thesis, 2016)Paring of nucleobases in deoxyribonucleic acid and the subsequent transcription of genes is arguably two of the most important processes for life. When subject to ultra violet (UV) light, one of the nucleobases, thymine, ... -
Porous filters of nanofibrillated cellulose
(Master thesis, 2011)Filters for air purification are predominantly produced of synthetic and non-biodegradable materials. In this work, a range of various air filters have been prepared from 100% pure cellulosic material, with the goal to ... -
Rapid Directional Recrystallisation of SiGe Fibres
(Master thesis, 2015)Fibre av \ce{SiGe} fremstilt ved flytende kjerne-trekking har blitt rekrystallisert ved bruk av to forskjellige teknikker: Sakte kj{\o}ling i en tubeovn og bevegende smeltesone-rekrystallisering med en \ce{CO2}-laser. To ... -
Recrystallization of silicon core fibers by CO2 laser annealing
(Master thesis, 2017)The innovation of introducing silicon in the core of optical glass fibers has lately been of great interest to the optoelectronics industry. The application areas of silicon core fibers are ranging from medical imaging and ... -
Self-Assembly of Magnetic Nanoparticles into Superstructures for Magnonics
(Master thesis, 2015)Magnonics is a young and evolving field with the potential to replace conventional electronics. This field relies on the use of spin waves, or magnons, rather than electrons as the information carrier in logic devices, ... -
The Effect of LiFSI Salt Concentration and Electrolyte Additives on the Performance of Silicon Anodes for Lithium-Ion Batteries
(Master thesis, 2018)Lithium-ion batteries (LIBs) are currently the dominant battery technology. However, the increasing technological demands in areas like energy storage, transportation and consumer electronics, require significant upgrades ... -
The Influence of Polarization on the Wetting of Anodes in the Hall-Héroult Process
(Master thesis, 2016)Improvements in the Hall Héroult process for aluminium electrolysis has lead to a reduction in energy consumption from 20-25 kWh/kg Al 70 years ago, down to around 13-14 kWh/kg Al on average today. In order to further ... -
Transmission Electron Microscopy Characterization of Sintered and Hot-Pressed Silicon Carbide
(Master thesis, 2016)Silicon carbide has excellent mechanical properties. Sintered or hot-pressed (HP) SiC is essen- tial for applications that require dense bodies. In this work, the microstructure of one solid state sintered SiC and one ...
