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…
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…
Microstructure analysis of bismuth absorbers for transition-edge sensor X-ray microcalorimeters
Daikang Yan, Ralu Divan, Lisa M. Gades +16
Transition-edge sensors (TESs) as microcalorimeters offer high resolving power, owning to their sharp response and low operating temperature. In the hard X-ray regime and above, th…
Eliminating the non-Gaussian spectral response of X-ray absorbers for transition-edge sensors
Daikang Yan, Ralu Divan, Lisa M. Gades +16
Transition-edge sensors (TES) as microcalorimeters for high-energy-resolution X-ray spectroscopy are often fabricated with an absorber made of materials with high Z (for X-ray stop…
Influences of Granular Constraints and Surface Effects on the Heterogeneity of Elastic, Superelastic, and Plastic Responses of Polycrystalline Shape Memory Alloys
Harshad M. Paranjape, Partha P. Paul, Hemant Sharma +5
Deformation heterogeneities within microstructures of polycrystalline shape memory alloys (SMAs) during superelastic stressing are studied using both experiments and simulations. I…
