Crystal Dislocations as Atomic Scale Ratchets
Wu-Rong Jian, Yifan Wang, Wei Cai
The symmetry of a system's response to external stimuli is a fundamental concept in physics and materials science. At the microscopic scale, breaking this symmetry to achieve a rec…
Laser, Vacuum, and Gas Reaction Chamber for Operando Measurements at NSLS-II's 28-ID-2
Lauren Y. Moghimi, Patrik Johansson, Subhechchha Paul +11
We present a laser reaction chamber that we developed for in-situ/operando X-ray diffraction measurements at the NSLS-II 28-ID-2 XPD (X-Ray Powder Diffraction) beamline. This chamb…
Formalism to Image the Dynamics of Coherent and Incoherent Phonon with Dark-Field X-ray Microscopy using Kinematic Diffraction Theory
Darshan Chalise, Yifan Wang, Mariano Trigo +1
Dark-field X-ray microscopy (DFXM) is a novel X-ray imaging technique developed at synchrotrons to image along the diffracted beam with a real space resolution of ~100 nm and recip…
Computing virtual dark-field X-ray microscopy images of complex discrete dislocation structures from large-scale molecular dynamics simulations
Yifan Wang, Nicolas Bertin, Dayeeta Pal +4
Dark-field X-ray Microscopy (DFXM) is a novel diffraction-based imaging technique that non-destructively maps the local deformation from crystalline defects in bulk materials. Whil…
Comment on "Comments regarding "Transonic dislocation propagation in diamond" by Katagiri, et al. (Science 382, 69-72, 2023)" by Hawreliak, et al. (arXiv:2401.04213)
Kento Katagiri, Tatiana Pikuz, Lichao Fang +24
In their comment (1), Hawreliak et al. claims that our observation of stacking fault formation and transonic dislocation propagation in diamond (2) is not valid as they interpret t…
Measuring the Burgers Vector of Dislocations with Dark-Field X-ray Microscopy
Dayeeta Pal, Yifan Wang, Ramya Gurunathan +1
The behavior of dislocations is essential to understand material properties, but their subsurface dynamics that are representative of bulk phenomena cannot be resolved by conventio…
X-ray induced grain boundary formation and grain rotation in Bi2Se3
Kento Katagiri, Bernard Kozioziemski, Eric Folsom +24
Optimizing grain boundary characteristics in polycrystalline materials can improve their properties. Many processing methods have been developed for grain boundary manipulation, in…
Dark-Field X-ray Microscopy for 2D and 3D imaging of Microstructural Dynamics at the European X-ray Free Electron Laser
Sara J. Irvine, Kento Katagiri, Trygve M. Ræder +26
Dark field X-ray microscopy (DXFM) can visualize microstructural distortions in bulk crystals. Using the femtosecond X-ray pulses generated by X-ray free-electron lasers (XFEL), DF…
Transonic Dislocation Propagation in Diamond
Kento Katagiri, Tatiana Pikuz, Lichao Fang +24
The motion of line defects (dislocations) has been studied for over 60 years but the maximum speed at which they can move is unresolved. Recent models and atomistic simulations pre…
Pushing the limits of flow strength in diamond
Anirudh Hari, Kento Katagiri, Wanghui Li +34
Extreme pressures and temperatures create conditions that allow even hard and brittle materials to deform plastically. Despite extensive research, the upper limits of flow strength…
