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

    Author : Jenny Ottosson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biocatalysis; enzyme catalysis; Candida antarctica lipase B; enantioselectivity; enthalpy; entropy; CALB; enantiomeric ratio; Bioengineering; Bioteknik;

    Abstract : 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. READ MORE

  4. 2. Physics of Viral Infectivity: Energetics of Genome Ejection

    Author : Meerim Jeembaeva; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; microfluidics.; differential scanning calorimetry; capsid; Key words: phage; osmotic suppression; DNA ejection; isothermal titration calorimetry; enthalpy;

    Abstract : All viruses that infect bacteria, plant, or animal cells involve a genome (RNA or DNA) that is encapsidated by a rigid protein shell. After delivery of the viral genome into the host cell, new capsid proteins, which are encoded by viral DNA or RNA, are expressed and self-assembled into new viral capsids. READ MORE

  5. 3. Ethyl(hydroxyethyl)cellulose and Some Model Uncharged Polymers: A Calorimetric Study of Their Interaction with Surfactants in Aqueous Solution

    Author : Geng Wang; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; calorimetry; differntial scanning; isothermal titration; enthalpy; electrolyte; micelles; self-association; thermal gelling; interaction; alkyltrimethylammonium halides; sodium dodecylsulfate; surfactants; polymers; ethyl hydroxylethyl cellulose; viscosity; phase behavior; self-diffusion NMR; Physics; Fysik; Chemistry; Kemi; Fysicumarkivet A:1997:Wang;

    Abstract : The interactions between uncharged polymers, e.g. ethyl(hydroxylethyl)cellulose (EHEC) and some model polymers, and ionic surfactants in aqueous solution has been studied by using isothermal titration and differential scanning calorimetry. READ MORE

  6. 4. Thermodynamic properties of humid air and their application in advanced power generation cycles

    Author : Xiaoyan Ji; Jinyue Yan; Umberto Desideri; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; air-water mixture; humid air; properties; wet cycles; dry air; water; enthalpy; entropy; heat capacity; density; evaporative gas turbine; compressed air energy storage; Chemical engineering; Kemiteknik;

    Abstract : Water or steam is added into the working fluid (often air) in gas turbines to improve the performance of gas turbine cycles. A typical application is the humidified gas turbine that has the potential to give high efficiencies, high specific power output, low emissions and low specific investment. READ MORE
