  2. 21. Simulations of ultrafast photon-matter interactions for molecular imaging with X-ray lasers

    Author : Ibrahim Eliah Dawod; Nicusor Timneanu; Carl Caleman; Adrian P. Mancuso; Lars Schäfer; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; X-ray free-electron laser; molecular dynamics; radiation damage; plasma simulations; density functional theory¸ coherent diffractive imaging; protein structure; X-ray crystallography; single particle imaging;

    Abstract : Biological structure determination has had new avenues of investigation opened due to the introduction of X-ray free-electron lasers (XFELs). These X-ray lasers provide an extreme amount of photons on ultrafast timescales used to probe matter, and in particular biomolecules. READ MORE

  4. 22. Picosecond X-ray Diffraction Studies of Bulk and Nanostructure Materials

    Author : Andrius Jurgilaitis; Atomfysik; []
    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

    Abstract : Properties of magnetic thin film devices cannot be understood without detailed knowledge of their structure. For this purpose, a variety of thin film and multilayer systems have been studied. READ MORE

  7. 25. Ordered arrays of low-dimensional Au and Pd : synthesis and in situ observations

    Author : Giuseppe Abbondanza; NanoLund: Centre for Nanoscience; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; nanowires NWs ; nanorods; nanoparticles; Au; Pd; Al; Al2O3; anodization; nano-porous anodic aluminum oxide; powder diffraction; x-ray diffraction; x-ray scattering; SAXS; WAXS; grazing-incidence; two-dimensional surface optical reflectance;

    Abstract : Electrodeposition of metals in templates of nano-porous anodic aluminum oxide (NP-AAO) is a versatile way of fabricating ordered arrays of metal nanowires. Thanks to the self-arranged long-range hexagonal order of the pores, electrodeposition in NP-AAO is an easily scalable bottom-up synthesis route and an attractive alternative to traditional top-down fabrication methods such as electron beam lithography.
