x-ray diffraction (XRD)steelradiation effectsHigh performance materials that can withstand radiation, heat, multiaxial stresses, and corrosive environment are necessary for the deployment of advanced nuclear energy systems. Nondestructive in situ experimental techniques utilizing high energy x-rays from ...
High energy synchrotron x-ray diffraction measurements of the as-spun and annealed ribbons have been carried out to determine their pair distribution functions (PDFs), using beamline 11-ID-C at the Advanced Photon Source, Argonne National Laboratory (ANL). The energy of the incident monochromatic...
Iron fluoride, an intercalation-conversion cathode for lithium ion batteries, promises a high theoretical energy density of 1922 Wh kg–1.However, poor electrochemical reversibility due to repeated breaking/reformation of metal fluoride bonds poses a grand challenge for its practical application. Her...
High-energy surface-sensitive x-ray diffraction (HESXRD) is a powerful high-energy photon technique (E > 70 keV) that has in recent years proven to allow a fast data acquisition for the 3D structure determination of surfaces and nanoparticles under in situ and operando conditions. The use of...
2.2.2 Synchrotron experiments In-situ, X-ray-diffraction (XRD) experiments were conducted at the A2 beamline of the Cornell high-energy synchrotron source (CHESS) to provide further details on precipitation kinetics during cooling. For this purpose, sheet-like samples measuring 12.7 × 152 × 1 ...
Results of Rietveld analysis of the synchrotron XRD data on Pb(Zr_xTi_1-x)O_3 (PZT) for 0.525\leqx\leq0.60 are presented to show the absence of rhombohedral phase on the Zr-rich side of the morphotropic phase boundary (MPB). Our results reveal that the structure of PZT is monoclinic ...
(Color online) Synthesis of HEA-NPs by continuous-flow reactor method: (a) schematic diagram of the synthesis method; (b) HAADF-STEM image and EDS elemental maps of IrPdPtRhRu HEA-NPs with a particle size of 1.32 nm, as well as (c) synchrotron X-ray diffraction (XRD) pattern and...
X射线衍射(XRD)[101]难以区分这两个结构. 在该工作中, 体系总能量E(Rc)=EBO(Rc)+Evib(Rc)E(Rc)=EBO(Rc)+Evib(Rc), 其中RcRc为高斯型原子核空间概率分布的中心. 该研究中通过引入反应坐标Q, RcRc看作反应坐标的函数, 即Rc(Q)= RIm¯3m+Q(RR3m−RIm¯3m)RIm3¯m+Q(RR3m−RIm3¯m...
Department of Energy (DOE) Office of Science User Facility operated for the DOE Office of Science by Argonne National Laboratory (ANL) under Contract No. DE-AC02-06CH11357. Portions of the synchrotron XRD measurements were done at the beamline 15U1 at Shanghai Synchrotron Radiation Facility (...
