  1. 1. CO2 separation using ionic liquid-based absorbents : thermodynamics and kinetics

    Author : Yifeng Chen; Xiaoyan Ji; Xiaohua Lu; Marcus Öhman; Congmin Wang; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ionic liquids; carbon dioxide; thermodynamics; kinetics; Energiteknik; Energy Engineering;

    Abstract : Ionic liquids (ILs) have shown great potential to be used as absorbents for CO2 separation owing to their unique properties such as immeasurably low vapour pressure, high thermal stability, high CO2 affinity, and tunable structure. A huge amount of researches have been carried out, and most of them focused on developing novel ILs for CO2 separation. READ MORE

    Abstract : 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. READ MORE

  3. 3. Thermodynamics of Protein Folding and Design

    Author : Erik Sandelin; Beräkningsbiologi och biologisk fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; 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;

    Abstract : 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. READ MORE

  4. 4. Hydrogen Storage Materials : Design, Catalysis, Thermodynamics, Structure and Optics

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

    Abstract : 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.
