Nanoscale Secondary Ion Mass Spectrometry for Quantifying Membrane Fouling: Fouling Layer Structure and Chemical Interaction

Advanced Science, EarlyView.
Nanoscale secondary ion mass spectrometry (Nano SIMS) is established as a powerful analytical tool to visualize and quantify the membrane fouling layers. ABSTRACT Membrane technology has garnered considerable attention for applications in wastewater treatment and resource recovery. Nevertheless, membrane fouling remains a major barrier, yet the lack of

Multifunctional Eutectic Mixtures Enable Integrated Recovery of U, Pu, and Sr From Nuclear Waste

Advanced Science, EarlyView.
A novel class of multifunctional eutectic mixtures, crafted from crown ether and organophosphorus molecules, achieves highly efficient, simultaneous recovery of uranium, plutonium, and strontium from nuclear waste. The material operates via a dual “coordination‐encapsulation” mechanism within self‐assembled reverse‐micelle structures, offering a ...

Atomic Interlayer Mo–N4 Sites Enable Rapid Charge Transfer and Efficient CO2 Photoreduction

Advanced Science, EarlyView.
This work achieved efficient CO2 activation and ultrafast interlayer electron transport in a 2D COF by constructing atomic‐level Mo‐N4‐induced interlayer electron bridges (IEB), thereby kinetically and thermodynamically co‐driving the photocatalytic coupling of CO2 reduction with 4‐methoxybenzyl alcohol oxidation.

Oxygen Isotope Fractionation Due to Non-Thermal Escape of Hot O from the Atmosphere of Mars

Atmosphere
Secondary minerals in SNC meteorites from Mars exhibit O isotope ratios believed to be consistent with the non-thermal escape of O from the atmosphere. The primary source of the non-thermal O is the dissociative- recombination of O2+ in the ionosphere. I

Revisiting Target‐Aware de novo Molecular Generation with TarPass: Between Rational Design and Texas Sharpshooter

Advanced Science, EarlyView.
TarPass provides a rigorous benchmark for target‐aware de novo molecular generation by jointly evaluating protein‐ligand interactions, molecular plausibility, and drug‐likeness on 18 well‐studied targets. Results show that current models often fail to consistently surpass random baseline in target‐specific enrichment, while post hoc multi‐tier virtual ...

Cobalt Single‐Atom Catalysts for Ultrafast Sulfamethoxazole Degradation: Unveiling the Chloride‐Ion‐Enhanced Formation of Co(IV)=O

Advanced Science, EarlyView.
An atomically dispersed Co–N4 single‐atom catalyst rapidly activates peroxymonosulfate to remove the antibiotic sulfamethoxazole from water. Common ions have little impact, but chloride dramatically speeds degradation by promoting a high‐valent Co(IV) = O oxidant via in situ HOCl–catalyst electron transfer.
