  1. 1. Green Propellants

    University dissertation from Stockholm : KTH

    Author : Martin Rahm; KTH.; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Quantum chemistry; reaction kinetics; ammonium dinitramide; high energy density materials; rocket propellants; chemical spectroscopy; polymer synthesis; NATURAL SCIENCES Chemistry Theoretical chemistry Quantum chemistry; NATURVETENSKAP Kemi Teoretisk kemi Kvantkemi; NATURAL SCIENCES Chemistry Physical chemistry; NATURVETENSKAP Kemi Fysikalisk kemi;

    Abstract : To enable future environmentally friendly access to space by means of solid rocket propulsion a viable replacement to the hazardous ammonium perchlorate oxidizer is needed. Ammonium dinitramide (ADN) is one of few such compounds currently known. READ MORE

  2. 2. Regioselective Heck Coupling Reactions Focus on Green Chemistry

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Karl S. A. Vallin; Uppsala universitet.; [2003]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical chemistry; Farmaceutisk kemi; PHARMACY Pharmaceutical chemistry; FARMACI Farmaceutisk kemi; Medicinal Chemistry; läkemedelskemi;

    Abstract : Carbon-carbon bond formation reactions are among the most important processes in chemistry, as they represent key steps in the synthesis of more complex molecules from simple precursors. This thesis describes mainly the development of novel regioselective applications of the mild and versatile palladium-catalyzed carbon-carbon coupling method, commonly known as the Heck reaction.

    Abstract : Popular Abstract in Swedish Tensider är amfifila molekyler, vilket innebär att de består av två delar. En av dessa är hydrofil (”vattenälskande”) och den andra är hydrofob (”vattenhatande”). READ MORE

  4. 4. Biomimetic Iron Complexes involved in Oxygenation and Chlorination A Theoretical Study

    University dissertation from Stockholm : Department of Physics, Stockholm University

    Author : Holger Noack; Stockholms universitet.; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; biomimetic; iron; density functional theory; intradiol; chlorination; adpic acid; diamond core; reactivity; NATURAL SCIENCES Chemistry Inorganic chemistry Bio-inorganic chemistry; NATURVETENSKAP Kemi Oorganisk kemi Bio-oorganisk kemi; NATURAL SCIENCES Chemistry Theoretical chemistry; NATURVETENSKAP Kemi Teoretisk kemi; Chemical Physics; kemisk fysik;

    Abstract : 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. READ MORE

  5. 5. Chemoinformetics for green chemistry

    University dissertation from Växjö, Kalmar : Linnaeus University Press

    Author : Tao Liu; Linnéuniversitetet.; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; QSPR; PLS; Chemometrics; Chemoinformatics; NATURAL SCIENCES Chemistry Environmental chemistry; NATURVETENSKAP Kemi Miljökemi; Environmental Chemistry; Miljökemi;

    Abstract : This thesis focuses on the development of quantitative structure-activity relationship (QSPR) models for physicochemical properties, e.g., vapor pressure and partitioning coefficients. Such models can be used to estimate environmental distribution and transformation of the pollutants or to characterize solvents properties. READ MORE
