Radiation‐Resistant Kr‐Selective MOF With Record Kr/Xe Selectivity at Elevated Pressure

open access: yesAdvanced Science, EarlyView.
ABSTRACT The separation of Kr/Xe from spent nuclear fuel off‐gas is critical, yet most current adsorbents exhibit Xe‐Kr co‐adsorption under elevated pressures, posing challenges for industrial pressure swing adsorption processes. Herein, we present and evaluate a metal‐organic framework, CALF‐20M‐w, engineered for molecular sieving separation of Kr/Xe ...

One‐Step, High‐Removal‐Rate and Low‐Damage Chemical Mechanical Polishing of InP Enabled by Hydrolysis Activated PF6− with In Situ Fluoride Passivation

open access: yesAdvanced Science, EarlyView.
In this work, we propose a CMP method for InP using NH4PF₆, which hydrolyzes under In3+ catalysis to form reactive species. These convert InP into low‐binding‐energy fluorides, facilitating removal and dissolution. The process delivers high material removal rates, smooth surfaces, and fluorine passivation that lowers defect density and improves ...

Metabolism‐Based Biomarkers for Rapid Phenotypic Antibiotic Susceptibility Testing

open access: yesAdvanced Science, EarlyView.
Metabolic differences emerging after antibiotic exposure provide rapid phenotypic signals of susceptibility and resistance. This review summarizes metabolic biomarkers for rapid phenotypic AST, associated with nutrient uptake, respiratory activity, metabolic reprogramming, and enzymatic function. ABSTRACT The accelerating global crisis of antimicrobial

Reduced Symmetry Metal–Organic Cage‐to‐Framework Materials

open access: yesAngewandte Chemie, EarlyView.
A series of Ag(I) MOFs was synthesised from organic cages of varying structure and symmetry as linkers. Minor variations in the cage linkers were shown to significantly influence the structures of the resulting MOFs. This work represents the first incorporation of reduced symmetry (including chiral), intrinsically porous building blocks into MOFs, and ...
