    Sammanfattning : In this work, the solubility of butyl paraben in 7 pure solvents and in 5 different ethanol-water mixtures has been determined from 1 ˚C to 50 ˚C. The solubility of ethyl paraben and propyl paraben in various solvents has been determined at 10 ˚C. LÄS MER

  2. 2. Thermodynamics of Protein Folding and Design

    Detta är en avhandling från Theoretical Physics, Lund University, Sölvegatan 14A, 223 62 Lund, Sweden

    Författare :Erik Sandelin; [2000]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; protein folding; hydrophobicity; Monte Carlo; sequence analysis; sequence assembly; shotgun sequencing; Mathematical and general theoretical physics; classical mechanics; quantum mechanics; relativity; gravitation; statistical physics; Matematisk och allmän teoretisk fysik; thermodynamics; termodynamik; Fysicumarkivet A:2000:Sandelin; statistisk fysik; relativitet; protein design; klassisk mekanik; kvantmekanik;

    Sammanfattning : The protein folding and protein design problems are addressed, using coarse-grained models with only two types of amino acids, hydrophobic and hydrophilic. In addition to hydrophobicity forces, the models contain sequence-independent local interactions which are found to strongly influence the thermodynamics of these models. LÄS MER

  3. 3. Profitability = f(G) Computational Thermodynamics, Materials Design and Process Optimization

    Detta är en avhandling från Theoretical Physics, Lund University, Sölvegatan 14A, 223 62 Lund, Sweden

    Författare :David Dilner; Malin Selleby; Mao Huahai; André Costa e Silva; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CALPHAD; steel; sulfide; steelmaking; thermodynamics; ICME; CALPHAD; stål; sulfid; ståltillverkning; termodynamik; ICME; Materials Science and Engineering; Teknisk materialvetenskap;

    Sammanfattning : The thesis starts by giving a motivation to materials modeling as a way to increase profitability but also a possibility decrease the environmental impact. Fundamental concepts of relevance for this work are introduced, this include the materials genome, ICME and of course the CALPHAD method. LÄS MER

  5. 5. Hydrogen Storage Materials Design, Catalysis, Thermodynamics, Structure and Optics

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Carlos Moysés Graça Araújo; Rajeev Ahuja; Ole Martin Løvvik; [2008]
    Nyckelord :Materials science; Hydrogen-storage materials; Density functional theory; Molecular dynamics; Catalysis; Thermodynamics; Optics; Materialvetenskap;

    Sammanfattning : Hydrogen is abundant, uniformly distributed throughout the Earth's surface and its oxidation product (water) is environmentally benign. Owing to these features, it is considered as an ideal synthetic fuel for a new world energetic matrix (renewable, secure and environmentally friendly) that could allow a sustainable future development.
