Combined scanning small-angle X-ray scattering and holography probes multiple length scales in cell nuclei

, 2022
X‐rays are emerging as a complementary probe to visible‐light photons and electrons for imaging biological cells. By exploiting their small wavelength and high penetration depth, it is possible to image whole, intact cells and resolve subcellular ...

Small Angle X-ray Scattering in Thin Iron Films [PDF]

Журнал нано- та електронної фізики, 2014
By small angle X-ray scattering (SAXS) and atomic force microscopy characteristic sizes are determined, structural features of thin iron films deposited by magnetron evaporation onto substrates from pyroceramics are established.

Diffractive small angle X-ray scattering imaging for anisotropic structures

Nature Communications, 2019
Mesoscale investigations of material microarchitecture using small angle X-ray scattering (SAXS) methods have been limited by long measurement times. Here, the authors present an X-ray diffractive optics method which enables single shot acquisition of ...

Small-angle X-ray scattering characteristics of mouse brain: Planar imaging measurements and tomographic imaging simulations. [PDF]

PLoS ONE, 2017
Small-angle x-ray scattering (SAXS) imaging can differentiate tissue types based on their nanoscale molecular structure. However, characterization of the coherent scattering cross-section profile of relevant tissues is needed to optimally design SAXS ...

Using small-angle X-ray scattering to investigate the compaction behaviour of a granulated clay

, 2015
The compaction behaviour of a commercial granulated clay (magnesium aluminium smectite, gMgSm) was investigated using macroscopic pressure-density measurements, X-ray diffraction (XRD), scanning electron microscopy (SEM), X-ray microtomography (XμT) and ...

A light‐triggered Time‐Resolved X‐ray Solution Scattering (TR‐XSS) workflow with application to protein conformational dynamics

FEBS Open Bio, EarlyView.
Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...

Low‐Cost, Large‐Scale Nanoporous Metals by Mechanical Alloying, Oxide Reduction, and Dealloying of Powders

Advanced Engineering Materials, EarlyView.
Powder metal processing provides scalable advantages in nanoporous (np) metal development. Mechanical alloying is used to produce unique precursors for hybrid nanopore formation by oxide reduction and dealloying. As demonstrated in np Ag, this approach improves process efficiency while promoting smaller ligaments and larger pores, both of which are ...
