  4. 22. Quantitative laser diagnostics of gas-phase potassium species in biomass combustion and gasification

    Author : Emil Thorin; Florian Schmidt; Markus Broström; Zhongshan Li; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermochemical conversion; pyrolysis; phosphorus; single pellet; entrained-flow; in situ; spectroscopy; photofragmentation; imaging; numerical modelling; fysik; Physics;

    Abstract : Thermochemical energy conversion processes, such as combustion and gasification, are applied worldwide for generation of electricity, heat and synthesis of chemicals. Today, these processes are mostly run on non-renewable, fossil fuels and constitute a major source of carbon dioxide emissions. READ MORE

  6. 24. Structure formation, phase transitions and drag interactions in multicomponent superconductors and superfluids

    Author : Karl Sellin; Egor Babaev; Anatoly Kuklov; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fysik; Physics;

    Abstract : Superconductivity and superfluidity are some of the most funda-mental and important phenomena of modern physics. However, muchtheoretical work for such systems so far has been restricted to the one-component case. READ MORE

  7. 25. Methods to Generate Size- and Composition Controlled Aerosol Nanoparticles

    Author : Martin Karlsson; Fasta tillståndets fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; differential mobility analyzer DMA ; transfer function; binary alloy nanoparticles; nanoparticle generator; thermal decomposition; Physics; sintering; Fysik; size selection; nanoparticles; aerosol technology; Fysicumarkivet A:2004:Karlsson;

    Abstract : This thesis describes experiments performed using different methods to produce aerosol nanoparticles with control over size and composition. The process included differential mobility analyzers (DMAs) as size-selecting instruments and tube furnaces for particle synthesis. READ MORE
