Acid Resistant and Highly Silver Selective Membranes Based on Charged Nanoporous 2D‐Materials

open access: yesSmall, EarlyView.
In this work, new membranes based on charged & nanoporous nanosheets with unprecedented selectivity to silver versus a wide range of other metallic ions are reported. Furthermore, a demonstrated and lead specific intralamellar lead pathway is demonstrated. A potential applicability for ubiquitous silver in WEEE is validated.

Covalent Functionalization of NiFe Layered Double Hydroxides using Tris(Hydroxymethyl)Aminomethane

open access: yesSmall, EarlyView.
Covalent functionalization of NiFe layered double hydroxides with tris(hydroxymethyl)aminomethane enables controlled growth, enhanced structural order, and improved processability. Temporary TRIS anchoring promotes stable water‐based inks and binder‐free electrode fabrication, leading to enhanced oxygen evolution activity and long‐term stability under ...

Anisotropic Swelling of a Single‐Crystalline Hydrogen‐Bonded Organic Framework Induced by Iodine Vapor Uptake

open access: yesSmall, EarlyView.
A single crystal of a layered hydrogen‐bonded organic framework (HOF) undergoes iodine uptake‐induced anisotropic swelling via adsorption into void channels and intercalation into the layers. ABSTRACT In this paper, we report that iodine vapor adsorption induces anisotropic swelling of a porous hydrogen‐bonded framework (HOF) composed of hexacarboxylic

Foamed Concrete Sealing Materials for Coal Seam Gas Drainage Boreholes: A Review

open access: yesSafety Science and Technology, EarlyView.
This study investigates the sealing performance of foamed concrete in gas drainage boreholes. By comparing leakage pathways (a, c) with sealed systems (b, d), the research demonstrates how foamed concrete effectively fills mining‐induced fractures and resists deformation.
