Time-resolved Laue diffraction of deforming micropillars.
We demonstrate real-time resolved white beam Laue diffraction during compression of micron-sized focused ion beam milled single crystals Au pillars, revealing the dynamical correlation between microstructure and plasticity. The evolution of the Laue patterns of the Au pillars demonstrates the occurrence of crystal rotation and strengthening is explained by plasticity starting on a slip system t...
متن کاملSharp-focusing Bragg-Fresnel zone plate with Laue diffraction geometry.
The impact of decreased zone height on the focal properties of hard X-ray Bragg-Fresnel zone plates has been studied by numerical simulation. Decreased zone height allows for smaller zone widths and, although the efficiency of the lens is decreased, the signal-to-background ratio in the focal plane of the lens remains at a comparatively high level. This is distinct from an analogous case of ord...
متن کاملStatic Laue diffraction studies on acetylcholinesterase.
Acetylcholinesterase (AChE) is one of nature's fastest enzymes, despite the fact that its three-dimensional structure reveals its active site to be deeply sequestered within the molecule. This raises questions with respect to traffic of substrate to, and products from, the active site, which may be investigated by time-resolved crystallography. In order to address one aspect of the feasibility ...
متن کاملInterface Residual Stresses in Dental Zirconia Using Laue Micro-diffraction
Due to their aesthetic value and high compressive strength, dentists have recently employed ceramics for restoration materials. Among the ceramic materials, zirconia provides high toughness and crack resistant characteristics. Residual stresses develop in processing due to factors including grain anisotropy and thermal coefficient mismatch. In the present study, polychromatic X-ray (Laue) micro...
متن کاملLaue transmission diffraction optics for thin film stress calculation
White beam Laue transmission diffraction topography has been used to determine the curvature of a crystalline substrate, from which the stress in the overlaying coating is determined. A detailed analytical method has been developed which correlates the introduction of curvature to the substrate in two orthogonal directions with attendant changes in the dimensions of a given topographic reflecti...
