  1. 11. Regulation of cytochrome P450 2E1 by hyperoxia and inflammatory factors, with special reference to the central nervous system

    Författare :Niclas Tindberg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Cytochrome P450 2E1 (CYP2E1) is a mammalian member of the large P450 gene superfamily. CYP2E1 is active in the metabolism of many small hydrophobic substrates, including general anesthetics, muscle relaxants, precarcinogens, and organic solvents. LÄS MER

  3. 12. Recovery of biochemicals from ABE fermentation broths using MFI adsorbents: A comparison between traditional beads and a structured adsorbent

    Författare :Abrar Faisal; Farid Akhtar; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical Technology; Kemisk teknologi;

    Sammanfattning : Energy demands of the world are ever increasing in this industrial era. Over reliance on petroleum-based fuels has a negative impact on the environment. In addition, with depleting reservoirs of fossil fuels, the need for new, sustainable fuels and chemicals is more urgent than ever. LÄS MER

  4. 13. Characterization of Ultrashort Pulses And Ultrafast Dynamics of Molecules In the Liquid Phase

    Författare :Ming Liu; KTH; []
    Nyckelord :Ultrafast Spectrascopy;

    Sammanfattning : This thesis reports an alternative method for fully acomplete characterization of the UV pump pulse and white lightcontinuum probe pulse, which is commonly used in the pump-probeexperiments to investigate the ultrafast dynamics of molecules.Besides that, real dynamics of infrared cyanine dye molecules(Methyl-DOTCI) and photo-induced dissociation of trihalide ions(I3-or I2Br-) solvated in different organic solvent has alsobeen carefully investigated.

  5. 14. Investigations intothe crystallization of butyl paraben

    Författare :Huaiyu Yang; Åke Rasmuson; Mårten Behm; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Butyl paraben; Solubility; Thermodynamic; Activity; Activity coefficient; Second order correlation; Liquid-liquid phase separation; Ternary phase diagram; Nucleation; Induction time; Free energy; Interfacial energy; Nuclei critical radius Cooling crystallization; Evaporation crystallization; Chemical engineering; Kemiteknik;

    Sammanfattning : In thisproject, solubility of butyl paraben in 7 puresolvents and 5 ethanol aqueous solvents has been determined at from 1 ℃to 50 ℃. Thermodynamic properties of butyl paraben have been measured by DifferentialScanning Calorimetey. LÄS MER

  7. 15. Development of Aerobic Oxidative N-Heterocyclic Carbene Catalysis via Multistep Electron Transfer and its Application

    Författare :Anton Axelsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; dihydropyranone; Michael addition; kinetics.; aerobic oxidation; acylation; N-heterocyclic carbene; green chemistry; Organocatalysis; electron transfer mediator; asymmetric synthesis;

    Sammanfattning : Oxidation reactions are ubiquitous in synthetic chemistry, but generally suffer from formation of large amounts of potentially toxic byproducts. Aerial oxygen represents an ideal oxidant since it is inexpensive, non-toxic and only forms water as a byproduct. LÄS MER
