  1. 1. Ionic Conduction and Bond Valence in Glasses

    Författare :Andreas Hall; [2008]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Neutron; Phosphate; Borate; reverse Monte Carlo; Glass; Bond Valence; Structure; Diffraction; X-ray; Ion Conduction;

    Sammanfattning : Ion conducting glasses are highly interesting for several different applications, among them, chemical sensors, smart windows with variable optical properties and as electrolytes in batteries. The last example can take full advantage of the ease with which a thin film (... LÄS MER

  2. 2. Phase transformation and stability studies of the Zr-H system

    Författare :Tuerdi Maimaitiyili; Lunds universitet.; Lund University.; Malmö University.; [2015]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; zirconium hydride; γ-ZrH; synchrotron X-ray diffraction; neutron diffraction; hydrogen charging; in situ phase transformation; hydrogen embrittlement; hydrogen induced degradation; NATURAL SCIENCES; NATURVETENSKAP; Sciences; Zirconium hydride; Nuclear materials; phase transformation; in-situ hydrogen charging; hydrogen related degradation; powder diffraction; Rietveld analysis;

    Sammanfattning : Popular Abstract in English Zirconium alloys are widely used in nuclear power reactors as cladding material for their fuels due to the high strength, good corrosion resistance and low neutron absorption cross-section, even in extreme environment, that is characteristic for zirconium. The element, however, also has strong affinity for hydrogen, and when both are present they readily react and form a family of compounds called hydrides. LÄS MER

    Sammanfattning : Perovskite based materials have great potentials for various energy applications and the search for new materials for uses in SOFCs has largely been concentrated to this class of compounds. In this search, we have studied perovskite phases in the system La2Co1+z(Ti1-xMgx)1-zO6, with 0  x 0.9 and z = 0.0, 0. LÄS MER

  4. 4. Trees, Queues and Alcohols

    Detta är en avhandling från Stockholm : Stockholms Universitet

    Författare :Per Sillrén; [2013]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Raman Scattering; Neutron Diffraction; Alcohols; EPSR; Quasi Elastic Neutron Scattering; Neutron Spin Echo; Monte Carlo Simulation; Hydrogen Bonded Liquids;

    Sammanfattning : Hydrogen bonded (H-bonded) materials, such as water, alcohols, sugars, and even DNA, are extremely important for biology, as well as chemical industry. Alcohols are used as solvents in paints, in perfumes, as cleaners, anti-freezers, or as an alternative to petrol in combustion engines. LÄS MER

  5. 5. Interaction of trehalose with water and protein for the understanding of biological stabilization

    Detta är en avhandling från ; Chalmers tekniska högskola; Gothenburg

    Författare :Christoffer Olsson; [2016]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; trehalose; protein; neutron scattering; water; neutron diffraction; amorphous; cryopreservation; biomolecule; EPSR; DSC;

    Sammanfattning : The understanding of biomolecular interactions with water and co-solutes opens up further understanding for the mechanism behind biomolecular stabilization. This is highly important for developing technologies aimed to preserve biological material. Such techniques include cryopreservation of for example pharmaceuticals or human organ transplants. LÄS MER
