Small-Angle Scattering from Nanoscale Fat Fractals

open access: yesNanoscale Research Letters, 2017
Small-angle scattering (of neutrons, x-ray, or light; SAS) is considered to describe the structural characteristics of deterministic nanoscale fat fractals.

Polyelectrolytes and small angle scattering

open access: yesEPJ Web of Conferences, 2018
We present an introduction to the application of small angle Xray and neutron scattering to the study of polyelectrolyte solutions. We aim to give a simple overview of the structural information that can be gained with these techniques. In particular, we

Regge limit of gauge theory amplitudes beyond leading power approximation

open access: yesJournal of High Energy Physics, 2020
We study the high-energy small-angle Regge limit of the fermion-antifermion scattering in gauge theories and consider the part of the amplitude suppressed by a power of the scattering angle.

Effect of annealing on the magnetic microstructure of high-pressure torsion iron: the relevance of higher-order contributions to the magnetic small-angle neutron scattering cross section

open access: yesIUCrJ, 2023
The development of higher-order micromagnetic small-angle neutron scattering theory in nanocrystalline materials is still in its infancy. One key challenge remaining in this field is understanding the role played by the microstructure on the magnitude ...

Structural characterisation of outer membrane proteins from Borrelia burgdorferi sensu lato by small-angle X-ray scattering [PDF]

open access: yes, 2016
Forming the interface between the bacterial cell and the host, the outer membrane of Borrelia is known to play a key role in pathogenicity. Although Borrelia burgdorferi sensu lato are considered to be Gram-negative, their outer membrane is unique ...

Neither Sphere nor Cube - Analyzing the Particle Shape Using Small-Angle Scattering and the Superball Model

open access: yes, 2021
Accurate characterization of the nanocrystal shape with high statistical relevance is essential for exploiting the strongly shape-dependent properties of cuboidal nanoparticles towards applications. This work presents the development of a new small-angle

DENSS-multiple: A structure reconstruction method using contrast variation of small-angle neutron scattering based on the DENSS algorithm

open access: yesBBA Advances, 2022
The 3D structure of biomacromolecules, such as protein and DNA/RNA, provide keys to understanding their biological functions. Among many structural biology techniques, small-angle scattering techniques with ab initio methods have been widely used to ...

Light scattering at small angles by atmospheric irregular particles: modelling and laboratory measurements [PDF]

open access: yesAtmospheric Measurement Techniques, 2014
We have investigated the behaviour of light scattering by particulates of various sizes (0.1 μm to 100 μm) at a small scattering angle (below 20°). It has been previously shown that, for a small angle, the scattered intensities are weakly dependent upon ...

Research on a Simulation Model of a Skywave Over-the-Horizon Radar Sea Echo Spectrum

open access: yesRemote Sensing, 2022
The capability of a skywave over-the-horizon radar (SWR) to achieve the continuous observation of a wide range of ocean dynamics parameters via a single ionospheric reflection has been demonstrated by many scholars.
