Microplastic Detectability Investigation in Soils Using X‐Ray Microtomography

X-Ray Spectrometry, EarlyView.
ABSTRACT X‐ray microtomography (microCT) is a promising tool for investigating microplastic (MP) contamination in soils, offering non‐destructive 3D visualization and quantitative analysis of particles embedded in complex matrices. This study evaluated its applicability by mixing plastic fragments (PET, PEHD, PS, and PP) with humus‐rich and sandy soils

Quantum refinement with electron diffraction and X‐ray free‐electron laser data: comparative study of ribonucleotide reductase dimetal site

Journal of Applied Crystallography, EarlyView.
For the first time quantum refinement has been performed with X‐ray free‐electron laser and microcrystal electron diffraction data for the dinuclear iron site in the R2a protein of ribonucleotide reductase. The method is shown to work well and can be used to determine the protonation state of the bridging solvent molecule and deduce photoreduction in ...

Non‐reciprocal spin excitations across the skyrmion–paramagnetic phase transition in MnSi

Journal of Applied Crystallography, EarlyView.
Inelastic neutron scattering shows that the non‐reciprocal nature of the magnons in the skyrmion phase of MnSi is maintained for high temperatures well beyond the skyrmion–paramagnetic phase transition.The magnetic excitations of the skyrmion lattice in MnSi comprise a multitude of individual modes, which are non‐reciprocal and thereby propagate ...

Structure and composition of supported lipid bilayers: a comparison between solvent‐assisted lipid bilayer and vesicle fusion methods

Journal of Applied Crystallography, EarlyView.
Neutron reflectometry is used to compare supported lipid bilayers formed by vesicle fusion and solvent‐assisted lipid bilayer (SALB) methods, revealing structurally comparable architectures with minor differences in acyl chain thickness and low residual solvent incorporation.

Spin‐contrast‐variation small‐angle neutron scattering study of fully and partially swollen silica‐filled rubber

Journal of Applied Crystallography, EarlyView.
We have elucidated the polymer adsorption layer structure in filler–rubber systems by conducting spin‐contrast‐variation small‐angle neutron scattering on partially and fully swollen filler–rubber samples with and without a silane coupling agent.We have elucidated the polymer adsorption layer structure in filler–rubber systems by conducting spin ...
