Knowledge gained through X-ray crystallography fostered structural determination of materials and greatly facilitated the development modern science technology in past century. Atomic details sample structures is achievable by crystallography, however, it only applied to crystalline structures. Imaging techniques based on coherent diffraction or zone plates are capable resolving internal structure non-crystalline at nanoscales, but still a challenge achieve atomic resolution. Here we...
Abstract Tremendous research efforts have been focused on the development of a water splitting system (WSS) to harvest hydrogen fuels, but currently available WSSs are complicated and cost‐ineffective mainly due applications noble platinum or different electrocatalysts. Herein, novel WSS comprising electricity generation from solar panels, storage in rechargeable zinc–air batteries (ZABs), electrolyzers, enabled by hybrid cobalt nanoparticles/N‐doped carbon embellished cloth (Co–NC@CC) as...
The design of high-performance overhead aluminum wires is challenging, due to the intrinsic trade-off strength-ductility and strength-electrical conductivity (EC). in-situ halide salt reactions were used introduce dual-size TiB2 particles into 6201 alloy obtain out-bound mechanical properties with slight sacrifice EC. With this strategy, ultimate tensile strength, elongation after fracture EC 4 wt%TiB2/6201Al composite are 360.9 MPa, 8.27% 53.5% IACS, respectively, these reference 325.0 7.8%...
An in-house designed transmission X-ray microscopy (TXM) instrument has been developed and commissioned at beamline BL18B of the Shanghai Synchrotron Radiation Facility (SSRF). is a hard (5–14 keV) bending-magnet recently built with sub-20 nm spatial resolution in TXM. There are two kinds mode: one based on using high-resolution-based scintillator-lens-coupled camera, other medium-resolution-based sCMOS camera. Here, demonstration full-field nano-tomography for high- Z material samples (...
Abstract Air sacs are thought to be the bellows for insect respiration. However, their exact mechanism of action as a remains unclear. A direct way investigate this problem is in vivo observation changes three-dimensional structures. Therefore, four-dimensional X-ray phase contrast microtomography employed solve puzzle. Quantitative analysis image series reveals that compression air sac during respiration bell crickets exhibits obvious anisotropic characteristics both longitudinally and...
Carbon fiber (CF)/pyrolytic graphite (PG) composites are promising structural materials for molten salt reactors because of their superior performance. Due to the minor density difference between CF and PG, existing methods impractical efficient three-dimensional characterization CF/PG composites. Therefore, in this study, a method based on in-line phase-contrast X-ray microtomography was developed solve aforementioned problem. Experimental results demonstrate that is suitable comprehensive...
In this work, the hybrid micron B4C particles (m-B4Cp) and nano SiC (n-SiCp) reinforced 6061Al matrix composites were prepared by powder metallurgy. The synergistic effects of m-B4Cp n-SiCp investigated. results showed that well dispersed in matrix, while uniformly distributed inside grains as at grain boundaries. coupled addition significantly refined size from 3.60 μm to 0.91 μm. synchrotron X-ray computed tomography (SR-CT) revealed volume pores increased with increase particle content....
To obtain accurate distributions of trace elements in biomedical samples nondestructively, the problems on absorption correction and radiation dose are confronted X‐ray fluorescence computed tomography. In this paper, absorption‐corrected ordered subsets expectation maximization (AC‐OSEM) algorithm is developed to solve these problems. Simulation results show that AC‐OSEM‐based tomography when only incident attenuation map known relatively fewer projections provided. addition, for samples,...

In this work, the microstructure evolution and mechanical behavior of extruded SiC/ZA63 Mg matrix composites are investigated via combined experimental study three-dimensional finite element modelling (3D FEM) based on actual 3D achieved by synchrotron tomography. The results show that average grain size composite increases from 0.57 µm 8 µm-SiC/ZA63 to 8.73 50 µm-SiC/ZA63. type texture transforms typical fiber in intense basal intensity sharply with increase SiC particle size. dynamic...
