Novel Role of Gut‐Derived Roseburia Intestinalis in Safeguarding Intestinal Barrier Integrity and Microenvironment Homeostasis During Arsenic Exposure

open access: yesAdvanced Science, EarlyView.
Arsenic exposure disrupts intestinal barriers and gut microenvironment. Fecal microbiota transplantation (FMT) alleviates arsenic‐induced damage, with gut‐derived Roseburia intestinalis (R.i) identified as a key protective strain. R.i administration counters arsenic toxicity through immunomodulatory pathways and metabolites.

Atomically Dispersed Zr‐N Moieties Modulate Fe Coordination for Robust Oxygen Reduction Electrocatalysis

open access: yesAdvanced Science, EarlyView.
The introduction of atomically dispersed Zr‐N moieties adjacent to Fe‐N4 centers forms a bimetallic coordination configuration. This structure modifies the local electronic environment of the Fe sites, weakening the adsorption of OH intermediates, suppressing Fe agglomeration and dissolution, and consequently enhancing both the catalytic activity and ...

Universal and Interpretable Descriptor to Design Dual‐atom Catalysts for Multi‐Type C–C Coupling with Ultrahigh C2+ Yield

open access: yesAdvanced Science, EarlyView.
CO2 capture and conversion, along with green hydrogen, offer considerable potential for achieving carbon neutrality and yielding high‐value multi‐carbon (C2+) products. Nevertheless, CO2‐to‐C2+ conversion is challenging, primarily due to the extreme inertness of CO2, the high C─C coupling barrier, and many competing reactions yielding C1 products. Dual‐

Rational Grain Boundary Segregation Enables Long‐Term Thermally Stable, Catalytically Active, and CO‐Tolerant Nanograined Metals

open access: yesAdvanced Science, EarlyView.
Grain boundaries endow nanocrystalline metals with unique functions but suffer thermal instability. In boron‐segregated platinum, stability depends critically on segregation level—sub‐equilibrium concentrations strengthen boundaries, whereas oversaturation induces decohesion.

Stabilizing Stretchable Organic Transistors Through Small‐Molecule Additive Blending for Ultra‐Sensitive Pesticide Detection

open access: yesAdvanced Science, EarlyView.
This study introduces a small‐molecule additive to improve the stability of stretchable organic field‐effect transistor (OFET). Furthermore, stretchable OFET‐based pesticide sensors with extended‐gate electrodes are constructed. It achieves highly sensitive and precise detection of chlorpyrifos pesticide, reaching a detection limit as low as 0.032 ppb.
