Ovine Bone Morphology and Deformation Analysis Using Synchrotron X-ray Imaging and Scattering

Quantum Beam Science, 2020
Bone is a natural hierarchical composite tissue incorporating hard mineral nano-crystals of hydroxyapatite (HAp) and organic binding material containing elastic collagen fibers. In the study, we investigated the structure and deformation of ovine bone by

Small-Angle Scattering of X-Rays from Extragalactic Sources by Dust in Intervening Galaxies [PDF]

, 1998
Gamma-ray bursts are now known to be a cosmological population of objects, which are often accompanied by X-ray and optical afterglows. The total energy emitted in the afterglow can be similar to the energy radiated in the gamma-ray burst itself.

CHROMIXS: automatic and interactive analysis of chromatography-coupled small-angle X-ray scattering data

Bioinform., 2017
Summary Size-exclusion chromatography (SEC) coupled to small-angle X-ray scattering (SAXS), also known as inline SEC-SAXS, is being increasingly used for the structural analysis of biological macromolecules, complexes and mixtures in solution.

Study of the morphology of semicrystalline poly(ethylene terephthalate) by hydrolysis etching [PDF]

, 1993
Semicrystalline poly(ethylene terephthalate) was hydrolysed in water at 180°C under elevated pressure and subsequently treated with ethanol, following the etching process first developed by Miyagi and Wunderlich.

Varying Collimation for Dark-Field Extraction

International 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

Investigating increasingly complex macromolecular systems with small-angle X-ray scattering

IUCrJ, 2014
The biological solution small-angle X-ray scattering (BioSAXS) field has undergone tremendous development over recent decades. This means that increasingly complex biological questions can be addressed by the method. An intricate synergy between advances

Simultaneous SAXS/SANS Method at D22 of ILL: Instrument Upgrade

Applied Sciences, 2021
A customized portable SAXS instrument has recently been constructed, installed, and tested at the D22 SANS instrument at ILL. Technical characteristics of this newly established plug-and-play SAXS system have recently been reported (J. Appl. Cryst. 2020,

Deciphering conformational transitions of proteins by small angle X-ray scattering and normal mode analysis.

Physical Chemistry, Chemical Physics - PCCP, 2016
Structural flexibility and conformational rearrangements are often related to important functions of biological macromolecules, but the experimental characterization of such transitions with high-resolution techniques is challenging.

Scattered X-rays in Obscured Active Galactic Nuclei and their Implications for Geometrical Structure and Evolution

, 2010
We construct a new sample of 32 obscured active galactic nuclei (AGNs) selected from the Second XMM-Newton Serendipitous Source Catalogue to investigate their multiwavelength properties in relation to the "scattering fraction", the ratio of the soft X ...

Structural and magnetic properties of CoPt mixed clusters [PDF]

, 2006
In this present work, we report a structural and magnetic study of mixed Co58Pt42 clusters. MgO, Nb and Si matrix can be used to embed clusters, avoiding any magnetic interactions between particles.
