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 کاملThe RATIO method for time-resolved Laue crystallography.
A RATIO method for analysis of intensity changes in time-resolved pump-probe Laue diffraction experiments is described. The method eliminates the need for scaling the data with a wavelength curve representing the spectral distribution of the source and removes the effect of possible anisotropic absorption. It does not require relative scaling of series of frames and removes errors due to all bu...
متن کاملSimulations of time-resolved x-ray diffraction in Laue geometry
A method for computer simulation of time-resolved x-ray diffraction (TRXD) in asymmetric Laue (transmission) geometry with an arbitrary propagating strain perpendicular to the crystal surface is presented. We present two case studies for possible strain generation by short-pulse laser irradiation: (i) a thermoelastic-like analytical model; (ii) a numerical model including the effects of electro...
متن کاملLaue Crystallography: It's show time
New crystallographic techniques make it possible to observe directly all of the intermediates in an enzymatic reaction. Such a series of structures can be combined to create a detailed movie of enzymatic catalysis.
متن کاملWatching a signaling protein function in real time via 100-ps time-resolved Laue crystallography.
To understand how signaling proteins function, it is crucial to know the time-ordered sequence of events that lead to the signaling state. We recently developed on the BioCARS 14-IDB beamline at the Advanced Photon Source the infrastructure required to characterize structural changes in protein crystals with near-atomic spatial resolution and 150-ps time resolution, and have used this capabilit...
