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

Small, 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.

Microporous Self‐Assembled Pd(II) Tetrahedral Cages for Rapid and Reversible Multi‐Phase Sequestration of Iodine and Methyl Iodide

Small, EarlyView.
This work reports a family of microporous, self‐assembled tetrahedral coordination cages that efficiently capture iodine, polyiodides, and methyl iodide from vapor, aqueous, and organic media. The cages display exceptional uptake capacities, rapid kinetics, and high selectivity, enabling the first dynamic vapor‐phase iodine capture by coordination ...

Cryogenic TDS Platform for Quantitative Hydrogen Isotope (H2/D2/HD) Separation via Quantum Sieving in Porous Materials

Small, EarlyView.
The AC‐TDS enables precise hydrogen isotope analysis over a wide temperature range (15–900 K), allowing both physisorption and chemisorption processes to be investigated under gas exposure conditions. Through calibration, this system achieves reliable quantitative desorption analysis, including direct quantification of H2, D2, and HD under mixed ...

Functional Chain Engineering in MOFs: Balancing Pore Size and Affinity for Noble Gas Separation

Small, EarlyView.
A series of mixed‐ligand metal‐organic frameworks (ML‐xC8) were synthesized by systematically incorporating C8 alkoxy substituents (C8BDC) into the IRMOF‐1 framework. As the C8BDC content increased, the pore size progressively decreased. ML‐80C8 (80% C8BDC) provided the optimal pore environment for selective Xe adsorption, exhibiting a markedly ...

Mechanistic Insight into H2S‐Induced Fluorescence Quenching in a Robust Metal–Organic Framework

Small, EarlyView.
An ultramicroporous Zn‐based metal‐organic framework, MFM‐520, enables reversible hydrogen sulfide adsorption and selective fluorescence sensing. Confinement of H2S within the pores perturbs ligand‐centered excited states through weak host‐guest interactions, enhancing non‐radiative decay pathways.
