  1. 6. Biomimetic Iron Complexes involved in Oxygenation and Chlorination : A Theoretical Study

    Författare :Holger Noack; Margareta R. A. Blomberg; Per E. M. Siegbahn; Martin Kaupp; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; biomimetic; iron; density functional theory; intradiol; chlorination; adpic acid; diamond core; reactivity; Bio-inorganic chemistry; Bio-oorganisk kemi; Theoretical chemistry; Teoretisk kemi; kemisk fysik; Chemical Physics;

    Sammanfattning : Biomimetic chemistry is directed towards the simulation of enzymatic reactivity with synthetic analogues. In this thesis a quantum chemical method has been employed to study the mechanism of highly reactive iron-oxo complexes involved in oxygenation and chlorination of organic substrates. LÄS MER

  3. 7. Synthesis, Characterisation and Properties of Biomimetic Biodegradable Polymers

    Författare :Fredrik Nederberg; Tim Bowden; Nicola Tirelli; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry; biodegradable polymers; biomimetic; phospholipid-like; phosphorylcholine; amphiphilic; ionomer; hemocompatible; non-adhesive; water uptake; reduced protein adsorption; protein delivery; Kemi; Chemistry; Kemi;

    Sammanfattning : The acceptance of blood contacting implants creating favorable conditions in vivo is decisively determined by their interaction with proteins that mediate inter cellular interactions with synthetic substrates. Adsorbed proteins can activate blood cascade systems like coagulation and complement that may result in serious blood clots, and/or immunological reactions. LÄS MER

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

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

    Sammanfattning : 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. LÄS MER

  5. 9. Reaction and Diffusion Phenomena in Biomimetic Nanoscale Reactors and Networks

    Författare :Kristin Sott; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; artificial cell; restricted geometries.; enzymatic reactions; micromanipulation; biomimetic; nanotubes; diffusion; Vesicles; networks; liposomes;

    Sammanfattning : Methods for construction of geometrically complex, fully connected surface-immobilized microscopic networks of phospholipid bilayer vesicles (1-50 µm in diameter) interconnected by lipid nanotubes (100-300 nm in diameter), have been developed. The networks have controlled connectivity and are well-defined with regard to the container size, content, angle between nanotube extensions, and nanotube length. LÄS MER

  7. 10. Biomimetic Software Engineering Techniques for Dependability

    Författare :Robert Feldt; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; automated testing; genetic programming; dependability; software engineering; biomimetic algorithms; design exploration; software development workbench; software visualization; software testing; evolutionary computation;

    Sammanfattning : The powerful information processing capabilities of computers have made them an indispensable part of our modern societies. As we become more reliant on computers and want them to handle more critical and difficult tasks it becomes important that we can depend on the software that controls them. LÄS MER
