  1. 1. Enthalpy and Entropy in Enzyme Catalysis A Study of Lipase Enantioselectivity

    Detta är en avhandling från Stockholm : KTH

    Författare :Jenny Ottosson; [2001]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biocatalysis; enzyme catalysis; Candida antarctica lipase B; enantioselectivity; enthalpy; entropy; CALB; enantiomeric ratio; TECHNOLOGY Bioengineering; TEKNIKVETENSKAP Bioteknik;

    Sammanfattning : Biocatalysis has become a popular technique in organic synthesis due to high activity and selectivity of enzyme catalyzed reactions. Enantioselectivity is a particularly attractive enzyme property, which is utilized for the production of enantiopure substances. LÄS MER

  2. 2. On Experimental and Theoretical Studies of Dynamics and Particle Production in p+Nucleus and Heavy Ion Reactions

    Detta är en avhandling från Division of Cosmic and Subatomic Physics, Department of Physics, Lund University

    Författare :Anton B Fokin; [1998]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; heavy-ion collisions; excitation function; subthreshold pion production; collective effects; entropy and chaos production; d p ratio; molecular dynamics; artificial neural networks; multifragmentation; Physics; Fysik; Fysicumarkivet A:1998:Fokin;

    Sammanfattning : Several experiments and theoretical models of intermediate energy heavy ion collision physics are presented in this thesis. Statistical and dynamical aspects of nuclear collisions are widely discussed these days, particularly in connection with the multifragmentation phenomenon and the possible link to a liquid-gas phase transition in the spinodal region of nuclear matter phase diagram.

  3. 3. Non-equilibrium thermodynamics at the microscopic scales

    Detta är en avhandling från Stockholm : Department of Physics, Stockholm University

    Författare :Sreekanth K Manikandan; Supriya Krishnamurthy; David Lacoste; [2020]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Non-equilibrium statistical Physics; entropy production; Theoretical Physics; teoretisk fysik;

    Sammanfattning : An inherent feature of small systems in contact with thermal reservoirs, be it a pollen grain in water, or an active microbe flagellum, is fluctuations. Even with advanced microscopic techniques, distinguishing active, non-equilibrium processes defined by a constant dissipation of energy to the environment from passive, equilibrium processes is a very challenging task and a vastly developing field of research.

  4. 4. Recovery of Kraft Black Liquor - Alternative Processes and System Analysis

    Detta är en avhandling från Stockholm : Department of Physics, Stockholm University

    Författare :Tobias Richards; [2001]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; shrinking-core; entropy; Kraft black liquor; equilibrium; thermodynamic efficiency; direct causticization;

    Sammanfattning : Besides the conventional recovery process, there are several possible processes whereby the cooking chemicals in kraft black liquor can be recovered. A part of one of the possible processes, direct causticization using titanate, has been studied in detail. LÄS MER

  5. 5. Efficiency Improvements in Waste-to-Energy Combustion Processes Method Development and Evaluation

    Detta är en avhandling från Borås : Högskolan i Borås

    Författare :Eboh Francis Chinweuba; Simon Harvey; [2019]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solid waste; exergy; entropy; higher heating value; improvement potential; waste-to-energy plant; efficiency improvement; cost evaluation; simulation; modelling; Resource Recovery; Resursåtervinning;

    Sammanfattning : is the energy recovery method. The electrical efficiency of this technology, however, is generally low when compared with other solid fuel-fired combustion plants as a result of low steam properties. Furthermore, there is lack of efficient methods to evaluate the performance of this system. LÄS MER
