MoS₂-Carbon Inter-overlapped Structures as Effective Electrocatalysts for the Hydrogen Evolution Reaction

Nanomaterials, 2020
The ability to generate hydrogen in an economic and sustainable manner is critical to the realization of a future hydrogen economy. Electrocatalytic water splitting into molecular hydrogen using the hydrogen evolution reaction (HER) provides a viable ...

Simulation of X-ray Parameters via Thomson Scattering [PDF]

مجلة التربية والعلم, 2012
: In this work, a computer program has been built to simulate some important X-ray parameters via Thomson scattering. X-ray energy dependence on the emitting and x-ray scattering angles for different incident electron energies were obtained.

The Scattering of X-rays [PDF]

Radiology, 1924
Abstract Present Status of the Problem.—The scattering of X-rays is one of the outstanding problems of electromagnetic radiation which has not been solved satisfactorily. All theories (based on classical electrodynamics) presented thus far do not explain either the diminution in the scattering coefficient, or the observed asymmetry in the scattering,

End-condition for solution small angle X-ray scattering measurements by kernel density estimation

Science and Technology of Advanced Materials: Methods, 2022
We develop a method for calculating the minimum X-ray exposure time for X-ray solution scattering experiments using statistical and mathematical approaches to enhance the measurement efficiency while maintaining data quality.

Fast acquisition protocol for X-ray scattering tensor tomography

Scientific Reports, 2021
Microstructural information over an entire sample is important to understand the macroscopic behaviour of materials. X-ray scattering tensor tomography facilitates the investigation of the microstructural organisation in statistically large sample ...

Stimulated resonant inelastic X-ray scattering in a solid

Communications Physics, 2022
X-ray free electron lasers provide brilliant light with sufficient intensity to strongly drive and probe nonlinear X-ray-matter interactions. Here, spectroscopy of Co/Pd multilayers reveals a nearly one-million-fold enhancement of stimulated resonant ...

X-ray Raman scattering study of aligned polyfluorene [PDF]

, 2006
We present a non-resonant inelastic x-ray scattering study at the carbon K-edge on aligned poly[9,9-bis(2-ethylhexyl)-fluorene-2,7-diyl] and show that the x-ray Raman scattering technique can be used as a practical alternative to x-ray absorption ...

X-ray flares, plateaus, and chromatic breaks of GRB afterglows from up-scattered forward-shock emission [PDF]

, 2007
Scattering of the forward-shock synchrotron emission by a relativistic outflow located behind the leading blast-wave may produce an X-ray emission brighter than that coming directly from the forward-shock and may explain four features displayed by Swift ...

Ray-tracing Simulations and Spectral Models of X-Ray Radiation in Dusty Media

The Astrophysical Journal, 2023
Dust can play an important role in shaping the X-ray spectra and images of astrophysical sources. In this work we report on the implementation of dust in the ray-tracing platform RefleX .
