Redox‐Active SnMoS x Chalcogels for Multi‐Electron Reductive Separation of Chromate and Pertechnetate

ABSTRACT High‐valent oxyanions, such as chromate (Cr VI O 4 2− ) and pertechnetate ( 99 Tc VII O 4 − ), are highly soluble, weakly coordinating, and exceptionally stable, making their removal from water and nuclear waste extremely challenging. Here, we report a redox‐coupled meta...

Developmentof a Flow-through Cell for UltrasonicExtraction (UE)─Single Particle (SP)─ICP-MS─anApproach for Nano/Microparticle Elemental and Isotopic Analysis

Abstract -Nanotechnology is a salient part of the scientific landscape, and analytical approaches are rapidly evolving to enable small-scale characterization of nano- and microparticle compositions and impurities. Here, a flow-through sonicating cell was developed for direct part...

Laser-InducedBreakdown Spectroscopy and Chemometricsof Diffuser Alloys for Tritium Production and Byproduct Purification

Abstract This study evaluates the potential of laser-induced breakdown spectroscopy for real-time monitoring of palladium and palladium-based alloys used for tritium recovery. Co-evolving gases include residual oxygen, nitrogen, methane, water, carbon monoxide, and carbon dioxide...
