  2. 1. Excitonic effects in ZnO

    Author : Shula Chen; Irina Buyanova; Weimin Chen; Ivan Ivanov; Linköpings universitet; []
    Keywords : ;

    Abstract : Zinc Oxide (ZnO) is an extensively researched II-VI wide bandgap semiconductor material. As a promising material for future optoelectronic and spintronic applications, it continues to attract enormous amount of interest. READ MORE

  4. 2. Ethanol from lignocellulose : physiological effects of inhibitors and fermentation strategies

    Author : Mohammad J Taherzadeh; Chalmers Univ of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Acetic acid; Agents; Cellulose; Enzyme inhibition; Feedback control; Fermentation; Hydrolysis; Metabolites; pH; Physiology; Wood; Yeast; Dilute acid hydrolyzate; Inhibitors; Lignocellulose; Physiological effects; Saccharomyces cerevisiae; Ethanol;

    Abstract : Fermentative ethanol production from dilute-acid hydrolyzates of wood using the yeast Saccharomyces cerevisiae was investigated. Of known inhibitors in hydrolyzates, acetic acid, furfural and hydroxymethyl furfural (HMF) were found in the highest concentrations (up to about 10 g/l). READ MORE

  5. 3. Physiological effects of conditioned medium and passage number on Spodoptera frugiperda Sf9 serum free cultures

    Author : Ingrid Svensson; Lena Häggström; Mats Martinelle; KTH; []

    Abstract : The aim of this study was to better understand the role of conditioned medium (CM) in Spodoptera frugiperda Sf9 insect cell proliferation and recombinant protein production using the baculovirus expression system. CM was found to stimulate cell proliferation. READ MORE

  6. 4. Theoretical study on nonlinearoptical properties of organicchromophores in solutions

    Author : Ke Zhao; Yi Luo; Ruth Pachter; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; two-photon absorption; solvent effects; aggregation effects; molecular dynamics simulation; Theoretical chemistry; Teoretisk kemi;

    Abstract : Inter-molecular interactions have significant influences on linear and nonlinear optical properties of molecules including one- and two-photon absorptions, emissions, and various high order nonlinear polarizations. The related investigation has become an active and challenging research area. READ MORE

  7. 5. Environmental management systems : policy implementation and environmental effects

    Author : Thomas Zobel; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kvalitetsteknik; Quality Technology and Management;

    Abstract : Corporate environmental management is becoming less driven by regulatory compliance and more driven by corporate strategy. In order to gain competitive advantage, systematically assure regulatory compliance and develop more efficient operations an increasing number of organisation adopt the environmental management system (EMS) tool.
