  1. 16. Characterization of ATP-dependent protein dynamics under native-like conditions

    Författare :Harsha Ravishankar; Magnus Andersson; Hans Wolf-Watz; Lise Arleth; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; proteins; membrane proteins; structural dynamics; ATPases; MD simulations; X-ray scattering; FTIR spectroscopy; ATP; TR-XSS; structural biology.; Biochemistry; biokemi;

    Sammanfattning : Proteins are biological macromolecules capable of accelerating biochemical reactions. To accomplish this, proteins undergo changes in their molecular structure. Advances in structural biology have resulted in ever-increasing numbers of high-resolution protein structures. LÄS MER

  3. 17. Elucidating Chemical and Electrochemical Side-Reaction Mechanisms in Li-ion Batteries

    Författare :Neeha Gogoi; Erik Berg; M. Rosa Palacín; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Lithium-ion battery; solid electrolyte interphase; electrolyte additives; reaction mechanism; ethylene carbonate; vinylene carbonate; tris trimethylsilyl phosphate; surface enhanced Raman spectroscopy; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry;

    Sammanfattning : Lithium-ion batteries constitute a leading technology that plays a major role in the transition towards sustainable transportation and power generation. The stability of modern batteries relies on a passivation layer formed on the negative electrode known as the solid electrolyte interphase (SEI). LÄS MER

  4. 18. Experimental and modelling studies of the thermophysical and thermochemical properties of some slag systems

    Författare :Lijun Wang; Seshadri Seetharaman; Kuo-Chih Chou; Miyuki Hayashi; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Teknisk materialvetenskap;

    Sammanfattning : In order to optimize the metallurgical processes it is necessary to improve the understandings of the industrial slag properties, which include thermophysical and thermochemical properties. In the present study Mass Triangle Model was applied to predict these properties. LÄS MER

  5. 19. Effect of fuel composition and combustion conditions on phosphorus behavior during combustion of biomass

    Författare :Joel Falk; Marcus Öhman; Anita Petterson; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energiteknik; Energy Engineering;

    Sammanfattning : Due to concerns for climate change and future supply of phosphorus fertilizer within agriculture, there has been an increased interest in the combustion of phosphorus containing waste residues and opportunity biomass fuels. Previous research has shown that during combustion, phosphorus has large impact on ash transformation reactions and may decrease or increase ash-related problems such as slag formation and bed agglomeration.

  7. 20. Surface-Controlled Chemical Vapor Deposition of Silicon Carbide

    Författare :Jing-Jia Huang; Henrik Pedersen; Urban Forsberg; Örjan Danielsson; Ulf Jansson; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Polycrystalline cubic silicon carbide, 3C-SiC, has long been investigated in the field of hard coating materials. The typical synthesis method for 3C-SiC coatings is thermal chemical vapor deposition (CVD) using either multicomponent precursors, e.g. methyltrichlorosilane, or a combination of single component precursors, e.
