1. 11. Coordination chemistry of late transition metals with PCP ligands. Synthesis, catalysis and mechanism

   Författare :Daniel Olsson; Centrum för analys och syntes; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organisk kemi; Organometallic chemistry; Metallorganisk kemi; Organic chemistry; Oorganisk kemi; Inorganic chemistry; Suzuki reaction; Stille reaction; catalysis; cyclometalation; C-H activation; PCP complex; POCOP ligand; PCP ligand; iridium; palladium; platinum;

   Sammanfattning : Abstract The work presented in this thesis discusses synthesis of PCP-complexes and utilisations of such organometallic compounds in catalysis. The complexes, obtained by intramolecular Csp3-H activation, are based on the metals palladium, platinum and iridium. LÄS MER

   Sammanfattning : 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. LÄS MER

5. 14. Studies of the Selective Catalytic Reduction of Nitrogen Oxides with Dimethyl Ether

   Författare :Stefanie Tamm; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; gas phase reaction; isocyanate; DME; acidic zeolite; reaction mechanism; lean deNOx; NO2 formation;

   Sammanfattning : Dimethyl ether (DME) is one of the most energy-efficient and low CO2 emitting alternative fuels when produced from biomass. Similar to other vehicles with combustion engines, vehicles running on DME will most likely need after-treatment technologies for the reduction of NOx emissions to meet the most stringent upcoming legislations.

7. 15. Intermediate State Stabilisation in Enzyme Catalysis Structural studies of two serine proteases and a photosynthetic reaction centre

   Författare :Gergely Katona; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; photosynthetic reaction centre; X-ray crystallography; structural mechanism; enzyme kinetics; serine protease; enzyme intermediate; enzyme catalysis;

   Sammanfattning : Enzymes play a key role in every organisms life. They catalyse chemical reactions and may also respond to external stimulus. The reoccurring theme of this thesis is how biologically relevant information can be gleaned from X-ray structures of the enzymes. LÄS MER
