X-ray scattering tensor tomography based finite element modelling of heterogeneous materials

npj Computational Materials
Among micro-scale imaging technologies of materials, X-ray micro-computed tomography has evolved as most popular choice, even though it is restricted to limited field-of-views and long acquisition times.

Comparative study of different scattering geometries for the proposed Indian X-ray polarization measurement experiment using Geant4 [PDF]

, 2010
Polarization measurements in X-rays can provide unique opportunity to study the behavior of matter and radiation under extreme magnetic fields and extreme gravitational fields. Unfortunately, over past two decades, when X-ray astronomy witnessed multiple order of magnitude improvement in temporal, spatial and spectral sensitivities, there is no (or ...

Advances in Electric Double-Layer Capacitor Research Using X-ray Scattering Techniques

Electrochemistry
A detailed understanding of the energy storage mechanism is essential to enhance the energy density of electrochemical capacitors. This necessity has led to the widespread use of in situ and operando measurements of electrochemical devices with ...

Structure and flexibility within proteins as identified through small angle X-ray scattering.

General Physiology and Biophysics, 2009
Flexibility between domains of proteins is often critical for function. These motions and proteins with large scale flexibility in general are often not readily amenable to conventional structural analysis such as X-ray crystallography, nuclear magnetic ...

Structure of Extremely Nanosized and Confined In-O Species in Ordered Porous Materials

, 2007
Perturbed-angular correlation, x-ray absorption, and small-angle x-ray scattering spectroscopies were suitably combined to elucidate the local structure of highly diluted and dispersed InOx species confined in porous of ZSM5 zeolite. These novel approach

BL-10C, the small-angle x-ray scattering beamline at the photon factory

, 2019
BL-10C at the Photon Factory is one of the world’s oldest small-angle X-ray scattering beamlines. In Spring 2014, the original beamline was scrapped and rebuilt as a beamline equipped with new optical components and an experimental system. Two detectors,

Average-Atom Model for X-ray Scattering from Warm Dense Matter [PDF]

arXiv, 2012
A scheme for analyzing Thomson scattering of x-rays by warm dense matter, based on the average-atom model, is developed. Emphasis is given to x-ray scattering by bound electrons. Contributions to the scattered x-ray spectrum from elastic scattering by electrons moving with the ions and from inelastic scattering by free and bound electrons are evaluated
