Linking Density and Nanoscale Crystallinity to Hydration in Nafion PEMFC Membranes: Insights From Experiment and Molecular Dynamics Simulations

open access: yesSmall Structures, EarlyView.
Molecular dynamics and experimental analysis show that higher crystallinity in Nafion enhances molecular packing, thereby increasing effective density. A proposed model bridges experimental and molecular‐scale observations by quantitatively linking water uptake to density variations, offering a predictive framework for optimising hydration and ...

Li6−xFe1−xAlxCl8 Solid Electrolytes for Cost‐Effective All‐Solid‐State LiFePO4 Batteries

open access: yesSmall Structures, EarlyView.
A new cost‐effective Li5.5Fe0.5Al0.5Cl8 solid electrolyte is presented. Upon the Al substitution to Li6FeCl8, its structure changed from the Suzuki‐phase to the spinel‐like phase while the 25°C ionic conductivity is increased from 3.1 × 10−6 to 3.9 ×10−5 S cm−1.

Olefin Polymerizations Oriented by Rational Designs of Group‐13 Compounds

open access: yesThe Chemical Record, EarlyView.
In coordination olefin polymerization chemistry, boron and aluminum compounds play important roles in both catalyst components and monomers. This personal account introduces our recent progress on the development of catalyst systems featured by the design of group‐13 counteranions, as well as the application of boronic acid‐crosslinked polyolefins to ...

Microplastic Detectability Investigation in Soils Using X‐Ray Microtomography

open access: yesX-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
