  1. 16. Application of Laser Techniques in Combustion Environments of Relevance for Gas Turbine Studies

    Författare :Andreas Lantz; Förbränningsfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Laser Diagnostics; PLIF; Laser-Induced Fluorescence; Combustion; Fuel visualization; LIF; Gas turbine; Flashback; Flame position; Swirling flame; Fysicumarkivet A:2012:Lantz;

    Sammanfattning : In the work presented in this thesis, different laser-based techniques were employed for measurements in different combustion devices. Laser-based techniques enable non-intrusive and in-situ measurements to be carried out, in which high spatial and temporal resolution can be obtained. LÄS MER

  3. 17. CALIBRATION OF CHROMATOGRAPHY MODELS

    Författare :Patrik Persson; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; film mass transfer resistance; Kemiteknik och kemisk teknologi; sorption kinetics; external volume; monolithic bed; shallow bed; packed bed; capillary model; detailed model; computer simulation; parameter estimation; diffusion; model calibration; Chromatography; modelling; proteins; Chemical technology and engineering;

    Sammanfattning : AbstractThis thesis is devoted to calibration of mathematical chromatography models. Chromatography models include unknown parameters that must be determined before the models can be applied to optimization or scale-up of a chromatography process. LÄS MER

  4. 18. Volatized Tellurium Interactions with Organics and with Boric Acid

    Författare :Fredrik Börjesson Sandén; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Volatile fission product; Severe nuclear reactor accident; Tellurium; boric acid;

    Sammanfattning : Tellurium is a volatile fission product with a complex chemistry that must be accounted for in case of a nuclear accident. Specifically, its interactions with organic species and with boric acid, both which are expected in the accident chemistry, are largely unknown. LÄS MER

  5. 19. On initiation of chemically assisted crack growth and crack propagation paths of branching cracks in polycarbonate

    Författare :Ulf Hejman; Malmö högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; stress corrosion; crack initiation; multiple cracking; polycarbonate; three point bending; stress corrosion cracking; polycarbonate; dissolution; branching; experiment; finite element modelling; stress corrosion; crack initiation; multiple cracking; polycarbonate; three point bending; branching.;

    Sammanfattning : Stress corrosion, SC, in some cases gives rise to stress corrosion cracking, SCC, which differs from purely stress intensity driven cracks in many aspects. They initiate and grow under the influence of an aggressive environment in a stressed substrate. They grow at low load and may branch. LÄS MER

  7. 20. Development of Methods for the Analysis of Polar Compounds in Environmental Matrices using LC/UV and LC/MS

    Författare :Johanna Minten; Margaretha Adolfsson-Erici; Leif Kronberg; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : In recent years, the awareness of environmentally hazardous compounds with polar and ionizable properties has intensified. Pharmaceuticals, the pesticide tebuconazole as well as the artificial sweetener sucralose are examples of such new, emerging, contaminants. LÄS MER
