  1. 21. Picosecond X-ray Diffraction Studies of Bulk and Nanostructure Materials

    Author : Andrius Jurgilaitis; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; solid-liquid transitions; X-ray diffraction and scattering; nanowires; laser beam impact phenomena; phonons in crystal lattices; Fysicumarkivet A:2012:Jurgilaitis;

    Abstract : Fast phenomena occurring after laser excitation were studied using time-resolved X-ray diffraction (TXRD). In most experiments, a femtosecond laser pulse was used to excite the sample, and X-rays were used as a probe. READ MORE

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

    University dissertation from Institute for Educational Sciences, Lund University, Sweden

    Author : Tuerdi Maimaitiyili; Lars Hallstadius; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Zirconium hydride; synchrotron X-ray diffraction; Nuclear materials; phase transformation; in-situ hydrogen charging; hydrogen related degradation; neutron diffraction; powder diffraction; Rietveld analysis; γ-ZrH; hydrogen embrittlement;

    Abstract : Zirconium alloys are widely used in the nuclear industry because of their high strength, good corrosion resistance and low neutron absorption cross-section. Zirconium has a strong affinity for hydrogen, however, and if hydrogen concentration builds up, the material will gradually degrade. READ MORE

  4. 24. Flash Diffractive Imaging in Three Dimensions

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Tomas Ekeberg; Janos Hajdu; Keith Nugent; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; X-ray; diffraction; mimivirus; three dimensional; phase retrieval; EMC; manifold embedding; CXI; FEL; free-electron laser; single particle; Physics with specialization in Biophysics; Fysik med inriktning mot biofysik;

    Abstract : During the last years we have seen the birth of free-electron lasers, a new type of light source ten billion times brighter than syncrotrons and able to produce pulses only a few femtoseconds long. One of the main motivations for building these multi-million dollar machines was the prospect of imaging biological samples such as proteins and viruses in 3D without the need for crystallization or staining.

  5. 25. Ionic Conduction and Bond Valence in Glasses

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

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

    Abstract : 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 (... READ MORE
