  1. 1. Catalytic Asymmetric Ketone and Alkene Reductions Using Transition Metal Complexes

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Klas Källström; Uppsala universitet.; [2006]
    Keywords : Organic chemistry; Catalytic; Asymmetric; Reductions; Ketones; Alkenes; Transition metal; Complexes; Organisk kemi;

    Abstract : This thesis contains seven papers dealing with iridium and ruthenium based catalytic asymmetric reductions, either of ketones into chiral alcohols, or olefins into chiral alkanes. The first part of the thesis describes how we have designed and evaluated new bicyclic ligands containing either N,S or N,N chelating atoms. READ MORE

  2. 2. A Study of Biomass Combustion Problems and the Selective Catalytic Oxidation of Ammonia

    University dissertation from Göran Olofsson, Department of Chemical Engineering, Lund University

    Author : Göran Olofsson; Lund University.; Lunds universitet.; [2004]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical technology and engineering; Kemiteknik och kemisk teknologi; Energy research; Reaction mechanism; Ammonia degradation; Pt CuO Al2O3 Catalysts; SCO; Selective Catalytic Oxidation; Catalytic hot gas cleaning; Bed agglomeration; NOx emissions; Fluidised bed; Biomass combustion; Biogas; Energiforskning;

    Abstract : Increasing awareness of the need of reducing CO2, NOx and SOx emissions from combustion systems has led to a strong interest in biomass as a fuel source. Using it in combination with fluidised bed combustion technology can lead to a lowering of NOx emissions to the atmosphere. READ MORE

  3. 3. Water Splitting Mechanism on 2D Catalytic Materials DFT based Theoretical Investigations

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : John Wärnå; Uppsala universitet.; [2019]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics and Astronomy specializing in Theoretical Physics; Fysik och astronomi med inriktning mot teoretisk fysik; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

    Abstract : In this thesis, we have envisaged systematic investigation to predict the water splitting mechanism on ultra-thin two-dimensional (2D) materials using cutting edge computation. Three different families of materials are considered as the case studies - i.MX2 (where M= W and Pt) based transition metal dichalcogenides, ii. READ MORE

  4. 4. A Catalytic and Mechanistic Investigation of Palladium-Phosphine Catalysed Aqueous Hydroxycarbonylation. Steric and Electronic Properties of the Ligands

    University dissertation from Organic Chemistry, Lund University

    Author : Adriana Ionescu; Lund University.; Lunds universitet.; [2006]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Oorganisk kemi; Inorganic chemistry; Naturvetenskap; Natural science; Isomerisation of hydroxyalkenes; Mechanism; Regioselectivity; Steric and electronic properties; Hydroxycarbonylation of styrene; Water-soluble phosphines; Palladium; Aqueous catalysis;

    Abstract : The steric and electronic properties of eight water-soluble phosphines (1-8) were investigated by different methods. Phosphines 1-6 were tested as ligands in palladium catalysed hydroxycarbonylation of styrene. READ MORE

  5. 5. Catalytic Formation of Amides

    University dissertation from Stockholm : Department of Organic Chemistry, Stockholm University

    Author : Fredrik Tinnis; Stockholms universitet.; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organic Chemistry; organisk kemi;

    Abstract : The amide functionality is a highly important chemical bond, found in a great number of synthetic products such as pharmaceuticals, polymers and agrochemicals. The focus of this thesis has been directed towards efficient, mild and environmentally friendly methods for amide formations. READ MORE
