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…
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…
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…
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…
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…
