The histone chaperones Vps75 and Nap1 form ring-like, tetrameric structures in solution [PDF]

open access: yes, 2013
NAP-1 fold histone chaperones play an important role in escorting histones to and from sites of nucleosome assembly and disassembly. The two NAP-1 fold histone chaperones in budding yeast, Vps75 and Nap1, have previously been crystalized in a ...

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

open access: yes, 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]

open access: yesЖурнал 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

open access: yesNature 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]

open access: yesPLoS 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 ...

Varying Collimation for Dark-Field Extraction

open access: yesInternational Journal of Biomedical Imaging, 2009
Although x-ray imaging is widely used in biomedical applications, biological soft tissues have small density changes, leading to low contrast resolution for attenuation-based x-ray imaging. Over the past years, x-ray small-angle scattering was studied as

Nanocomposites of Au/Disentangled UHMWPE: A Combined Optical and Structural Study

open access: yesMolecules, 2020
The term disentangled refers to polymers with fewer entanglements in the amorphous regions, a metastable condition that can significantly affect the material’s properties and processing behavior.
