Structural changes across thermodynamic maxima in supercooled liquid tellurium: a water-like scenario
Peihao Sun, Giulio Monaco, Peter Zalden +10
Liquid polymorphism is an intriguing phenomenon which has been found in a few single-component systems, the most famous being water. By supercooling liquid Te to more than 130 K be…
BraggNN: Fast X-ray Bragg Peak Analysis Using Deep Learning
Zhengchun Liu, Hemant Sharma, Jun-Sang Park +5
X-ray diffraction based microscopy techniques such as High Energy Diffraction Microscopy rely on knowledge of the position of diffraction peaks with high precision. These positions…
Big Data Staging with MPI-IO for Interactive X-ray Science
Justin M. Wozniak, Hemant Sharma, Timothy G. Armstrong +3
New techniques in X-ray scattering science experiments produce large data sets that can require millions of high-performance processing hours per week of computation for analysis.…
High-energy coherent X-ray diffraction microscopy of polycrystal grains: first steps towards a multi-scale approach
Siddharth Maddali, Jun-Sang Park, Hemant Sharma +7
We present proof-of-concept imaging measurements of a polycrystalline material that integrate the elements of conventional high-energy X-ray diffraction microscopy with coherent di…
Phase retrieval for Bragg coherent diffraction imaging at high X-ray energies
Siddharth Maddali, Marc Allain, Wonsuk Cha +6
Coherent X-ray beams with energies keV can potentially enable three-dimensional imaging of atomic lattice distortion fields within individual crystallites in bulk polycry…
Multi-element Germanium Detectors for Synchrotron Applications
Abdul K. Rumaiz, Anthony J. Kuczewski, Joseph Mead +14
We have developed a series of monolithic multi-element germanium detectors, based on sensor arrays produced by the Forschungzentrum Julich, and on Application-specific integrated c…
Sparse recovery of undersampled intensity patterns for coherent diffraction imaging at high X-ray energies
Siddharth Maddali, Irene Calvo-Almazan, Jonathan Almer +5
Coherent X-ray photons with energies higher than 50 keV offer new possibilities for imaging nanoscale lattice distortions in bulk crystalline materials using Bragg peak phase retri…
Study of the Mechanical Behavior of the Hydride Blister/Rim Structure in Zircaloy-4 using in-situ Synchrotron X-ray Diffraction
Jun-li Lin, Xiaochun Han, Brent J. Heuser +1
High-energy synchrotron X-ray diffraction was utilized to study the mechanical response of the f.c.c -hydride phase, the intermetallic precipitation with hexagonal C14 lave phas…
Significant elastic anisotropy in TiAlN alloys
Ferenc Tasnadi, Igor A. Abrikosov, Lina Rogström +3
Strong compositional-dependent elastic properties have been observed theoretically and experimentally in TiAl N alloys. The elastic constant, C, changes by more…
