    Sammanfattning : The concept of energy production through the fusion of two light nuclei has been studied since the 1950’s. One of the major problems that fusion scientists have encountered is the confinement of the hot ionised gas, i.e. the plasma, in which the fusion process takes place. LÄS MER

  3. 2. Selective oxidation over mixed oxide catalysts

    Författare :Robert Häggblad; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; propane; catalysis; Selective oxidation; transition metal oxides; vanadium; molybdenum; methanol oxidation; ammoxidation; propene; acrylonitrile; formaldehyde;

    Sammanfattning : Since the metal oxide catalysts used in many chemical processes show very high selectivity for the products aimed at, both today and in the future, they play a key role in the environmentally and economically sustainable production of chemical intermediates. Two processes of this sort have been studied in the thesis: the ammoxidation of propane and propene over a Mo-V-Nb-Te-oxide catalyst and the selective oxidation of methanol over vanadium-based catalysts.

  4. 3. Growth, processing and characterization of group IV materials for thermoelectric applications

    Författare :Mohammad Noroozi; Muhammet .S Toprak; Henry .H Radamson; Raşit Turan; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Thermoelectric; SiGe; GeSn Si ; Chemical vapor deposition; Nanowires; Fysik; Physics;

    Sammanfattning : Discover of new energy sources and solutions are one of the important global issues nowadays, which has a big impact on economy as well as environment. One of the methods to help to mitigate this issue is to recover wasted heat, which is produced in large quantities by the industry, through vehicle exhausts and in many other situations where we consume energy.
