SAXSMoW 2.0: Online calculator of the molecular weight of proteins in dilute solution from experimental SAXS data measured on a relative scale

Protein Science, 2018
Knowledge of molecular weight, oligomeric states, and quaternary arrangements of proteins in solution is fundamental for understanding their molecular functions and activities.

Microsecond hydrodynamic interactions in dense colloidal dispersions probed at the European XFEL

IUCrJ, 2021
Many soft-matter systems are composed of macromolecules or nanoparticles suspended in water. The characteristic times at intrinsic length scales of a few nanometres fall therefore in the microsecond and sub-microsecond time regimes.

Decoupling of size and shape fluctuations in heteropolymeric sequences reconciles discrepancies in SAXS vs. FRET measurements

Proceedings of the National Academy of Sciences of the United States of America, 2017
Significance Conformational properties of unfolded and intrinsically disordered proteins (IDPs) under native conditions are important for understanding the details of protein folding and the functions of IDPs.

SAXS measurements of azobenzene lipid vesicles reveal buffer-dependent photoswitching and quantitative Z→E isomerisation by X-rays

Nanophotonics, 2022
Photoresponsive materials feature properties that can be adjusted by light near-instantaneously, reversibly, and with high spatiotemporal precision. There is considerable interest in maximising the degree of photoswitching, and in measuring this degree ...

Extreme-SAX: Extreme Points Based Symbolic Representation for Time Series Classification [PDF]

Lecture Notes in Computer Science 12393, Springer 2020,, 2020
Time series classification is an important problem in data mining with several applications in different domains. Because time series data are usually high dimensional, dimensionality reduction techniques have been proposed as an efficient approach to lower their dimensionality. One of the most popular dimensionality reduction techniques of time series

Decellularized pericardium tissues at increasing glucose, galactose and ribose concentrations and at different time points studied using scanning X-ray microscopy

IUCrJ, 2021
Diseases like widespread diabetes or rare galactosemia may lead to high sugar concentrations in the human body, thereby promoting the formation of glycoconjugates. Glycation of collagen, i.e.

Influence of supercritical CO2-H2O fluid on nanopore structure of coal based on small angle X-ray scattering

Meikuang Anquan, 2023
The change in nanopore structure of coal with the presence of water due to supercritical CO2 (SCCO2) exposure could significantly affects CO2 storage in target coal seams.

An in situ SAXS investigation of the formation of silver nanoparticles and bimetallic silver–gold nanoparticles in controlled wet-chemical reduction synthesis

Nanoscale Advances, 2019
We present a study on the formation of silver (Ag) and bimetallic silver–gold (AgAu) nanoparticles monitored by in situ SAXS as well as by ex situ TEM, XRD and UV-vis analysis in a flow reactor at controlled reaction temperature.

Automatic calibration system of small angle X-ray scattering experiment station at SSRF

He jishu, 2021
BackgroundThe quality of the experimental data is closely related to the optimal optical conditions of the end-station in the small-angle X-ray scattering (SAXS) beamline (lower scattering background, accurate beam intensity before and after the sample ...
