  2. 21. Flavins as Biomimetic Catalysts for Sulfoxidation by H2O2 : Catalyst Immobilization in Ionic Liquid for H2O2 Oxidations

    Author : Auri Lindén; Jan-Erling Bäckvall; Peter Somfai; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; biomimetic; oxidation; catalysis; ionic liquid; hydrogen peroxide; Organic chemistry; Organisk kemi;

    Abstract : This thesis deals with the development of catalytic oxidation reactions utilizing hydrogen peroxide as terminal oxidant. The main focus has been to find flavin catalysts that are easy to handle and stable to store but still able to perform the desired reaction. READ MORE

  4. 22. Sensorimotor transformations during grasping movements

    Author : Daniel Säfström; Benoni B. Edin; Melvyn A. Goodale; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; sensorimotor transformation; sensory integration; visuomotor map; human physiology; adaptation; grasping; sensory substitution; Physiology; Fysiologi;

    Abstract : ‘Sensorimotor transformations’ are processes whereby sensory information is used to generate motor commands. One example is the ‘visuomotor map’ that transforms visual information about objects to motor commands that activates various muscles during grasping movements. READ MORE

  5. 23. Development of Biomimetic Catalytic Systems for Selective Oxidations with H2O2 and O2

    Author : Mikael Johansson; Jan-Erling Bäckvall; Matthias Beller; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biomimetic oxidations; catalyst immobilization; dihydroxylation; sulfoxidation; flavin; Chemistry; Kemi; Organic Chemistry; organisk kemi;

    Abstract : Four different catalytic systems were studied for biomimetic coupled oxidations using H2O2 or O2. In the first example, osmium tetroxide works as a substrate-selective catalyst for dihydroxylation of olefins. Electron transfer to H2O2 is facilitated by electron transfer mediators (ETMs).

  6. 24. Syntheses of functionalized Phe-Gly dipeptidomimetics

    Author : Wei Berts; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical chemistry; Farmaceutisk kemi; Pharmaceutical chemistry; Farmaceutisk kemi; Organic Pharmaceutical Chemistry; organisk farmaceutisk kemi;

    Abstract : The complete series of Boc-protected C-4 mono- and difluoroallyl Phe-Gly dipeptidomimetics and their corresponding saturated derivatives has been synthesized. A mechanism that rationalizes the formation of the two isomeric allylic mono-fluorides from an allylic alcohol with diethylaminosulfur trifluoride (DAST) has been investigated. READ MORE

  7. 25. Nanocrystalline Tungsten Trioxide Thin Films : Structural, Optical and Electronic Characterization
