  1. 11. Structure evolution of spin-coated phase separated EC/HPC films

    Författare :Pierre Carmona; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; spin-coating; controlled drug release; porous film; drug delivery; confocal laser scanning microscope; kinetics; phase separation mechanisms; cellulose; biopolymer; phase separation;

    Sammanfattning : Porous phase-separated films made of ethylcellulose (EC) and hydroxypropylcellulose (HPC) are commonly used for controlled drug release. The structure of these thin films is controlling the drug transport from the core to the surrounding liquid in the stomach or intestine. However, detailed understanding of the structure evolution is lacking. LÄS MER

  3. 12. Physiology of Caldicellulosiruptor saccharolyticus: a hydrogen cell factory

    Författare :Karin Willquist; Teknisk mikrobiologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; growth activation; hydrogen tolerance; hydrogen yields CO2 inhibition; physiology; enzyme kinetics; Caldicellulosiruptor saccharolyticus; biohydrogen; energy metabolism;

    Sammanfattning : A high substrate conversion efficiency is a prerequisite for an economically feasible biohydrogen production. Caldicellulosiruptor saccharolyticus is a strictly anaerobic extreme thermophilic bacterium that is able to convert the theoretical maximum of 4 mol/mol glucose to H2. LÄS MER

  4. 13. Molecular investigations of atmospherically relevant interface processes: ice formation and water accommodation on ice and organic surfaces

    Författare :Xiangrui Kong; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; atmosphere; kinetics; Environmental molecular beam; ice nucleation; supersaturation; accommodation coefficient; phase transition; alcohols; green chemistry;

    Sammanfattning : Clouds and aerosols play important roles in the climate system by affecting on atmospheric chemistry, the radiation budget of the atmosphere, and the water cycle including the formation of precipitation. Climate models with predictive power require quantitative descriptions of aerosols and clouds, but several key processes remain to be fully understood. LÄS MER

  5. 14. Photon stimulated CVD of amorphous carbon thin films : By Mikael Lindstram

    Författare :Mikael Lindstam; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry; photolysis; thermal activation; CVD; amorphous carbon; modelling; kinetics; Kemi; Chemistry; Kemi; Inorganic Chemistry; oorganisk kemi;

    Sammanfattning : Amorphous carbon has attracted much interest for several decades now because of its complex crystal structure and microstructure. Depending on the carbon sp2/sp3 bonding ratio, these materials yield a broad spectrum of useful properties; which can be tailored for specific applications. LÄS MER

  7. 15. Investigations on the Physico-Chemical Phenomena during Induration of a Magnetite Pellet

    Författare :T. K. Sandeep Kumar; Charlotte Andersson; Chris Pistorius; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Magnetite pellet; Oxidation; Sintering; Optical Dilatometer; Kinetics; Modeling; Single Pellet; Thermo Gravimetric Analyzer; Process Metallurgy; Processmetallurgi;

    Sammanfattning : In the era of globalization with increasing environmental awareness, sustainable utilization of the available resources is a necessity; iron ores are no exception. Pelletization, being one of the increasingly practiced agglomeration techniques for the iron ore fines as well as other solid wastes from steel plants. LÄS MER
