  2. 1. Lipase and ω-Transaminase : Biocatalytic Investigations

    Author : Maria Svedendahl; Per Berglund; Stefan Stefan Lutz; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Candida antarctica lipase B; enzyme catalysis; enzyme catalytic promiscuity; molecular modeling; ω-transaminase; Biochemistry; Biokemi;

    Abstract : In a lipase investigation, Candida antarctica lipase B (CALB) are explored for enzyme catalytic promiscuity. Enzyme catalytic promiscuity is shown by enzymes catalyzing alternative catalytic transformations proceeding via different transition state structures than normal. READ MORE

  4. 2. Pea carbonic anhydrase : a kinetic study

    Author : Inga-Maj Johansson; W. Richard Chegwidden; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Pisum sativum; carbonic anhydrase; kinetic studies; site-directed mutagenisis;

    Abstract : The enzyme carbonic anhydrase (CA), catalysing the interconversion between CO2 and HCO3', has long been known to be present in plants as well as in animals. Several of the animal isozymes, but none of the plant CAs, have been extensively studied. READ MORE

  5. 3. Iron catalyzed C-C coupling reactions - mechanistic investigations

    Author : Anna Hedström; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; iron; homogenous catalysis; cross coupling; C-C bond formation; reaction mechanisms; kinetic investigations; competitive Hammett study; density functional theory;

    Abstract : The mechanism of the iron catalyzed cross coupling of aryl electrophiles with alkyl Grignard reagents was studied. The reaction proceeds via a rate-limiting oxidative addition of the aryl halide to an Fe(I) complex generated in situ. A transmetalation from an aryl Grignard reagent occurs either before or after the oxidative addition. READ MORE

  6. 4. Kinetic investigations of combustion of small oxygenated aliphatic hydrocarbons – modeling and experiments

    Author : Gianluca Capriolo; Förbränningsfysik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kinetic modelling; Nitric Oxide; n-propanol; i-propanol; propanal; LIF; Fysicumarkivet A:2020:Capriolo;

    Abstract : The depletion of oil reserves and the increasingly stringent European Union regulation of air pollution have forced researchers and manufacturers to search for cleaner and sustainable substitutes to petroleum‐based transportation fuels. Biofuels like small aliphatic alcohols are of increasing interest as alternatives to fossil fuels, as they offer long‐term fuel‐source regenerability. READ MORE

  7. 5. MECHANISTIC INVESTIGATIONS OF TRANSITION METAL CATALYZED REACTIONS

    Author : Jonatan Kleimark; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; alkene insertion; allylic alkylation; catalysis; cross coupling; density funtional theory; free energy surface; iron; kinetic investigation; Mizoroki-Heck reaction; nickel; palladium; reaction mechanism; sulfinylation; transition metal;

    Abstract : Transition metal catalyzed reactions have had a large impact on the human progress for the last century. Several extremely important areas, such as the agricultural industry and the plastic industry, have benefited from this development. READ MORE
