Understanding ultrafast x-ray 'echoes' diffracted from single crystals
Angel Rodriguez-Fernandez, Dmitry Karpov, Steven Leake +2
Multiple x-ray beams generated by interference processes in perfect crystals were imaged with a resolution of about 100nm using tele-ptychography in the diffraction direction. Thes…
Electric Field Driven Domain Wall Dynamics in BaTiO3 Nanoparticles
Jialun Liu, David Yang, Ana F. Suzana +2
We report a detailed investigation into the response of single BaTiO3 (BTO) nanocrystals under applied electric fields (E-field) using Bragg Coherent Diffraction Imaging (BCDI). Ou…
Variable-wavelength quick scanning nano-focused X-ray microscopy for in situ strain and tilt mapping
Marie-ingrid Richard, Thomas W Cornelius, Florian Lauraux +7
Compression of micro-pillars is followed in situ by a quick nano-focused X-ray scanning microscopy technique combined with three-dimensional reciprocal space mapping. Compared to o…
Imaging the Breathing of a Platinum Nanoparticle in Electrochemical Environment
Clément Atlan, Corentin Chatelier, Maxime Dupraz +9
Surface strain is widely used in gas phase catalysis and electrocatalysis to control the binding energies of adsorbates on metal surfaces. However, or strain…
A convolutional neural network for defect classification in Bragg coherent X-ray diffraction
Bruce Lim, Ewen Bellec, Maxime Dupraz +8
Coherent diffraction imaging enables the imaging of individual defects, such as dislocations or stacking faults, in materials.These defects and their surrounding elastic strain fie…
Bragg Coherent Imaging of nanoprecipitates: role of superstructure reflections
Maxime Dupraz, Steven J. Leake, Marie-Ingrid Richard
Coherent precipitation of ordered phases is responsible for providing exceptional high temperature mechanical properties in a wide range of compositionally complex alloys (CCAs). O…
