Polypyrrole Nanofibrous Aerogel for Pressure Sensing and Anionic Contaminant Remediation

Small, EarlyView.
Nanofibrous aerogels (NFAs), highly porous ultralow‐density networks of entangled nanofibers, are conformally coated with polypyrrole (PPy) to provide a multifaceted material platform. Leveraging NFA's high surface area and mechanically robust structure with the conductive properties of PPy enables pressure‐responsive sensing for flexible electronics ...

In Situ Derived Fe/FexOy Janus Electrocatalyst for Efficient Nitrate‐to‐Ammonia Conversion via Intensifying Nitrate Affinity and Active Hydrogen Supply

Small, EarlyView.
A Janus electrocatalyst, Fe/FexOy is facilely synthesized via in situ reconstruction of β‐FeOOH. In particular, the electronically coupled Fe crystal phase with FexOy exhibits high NO3RR performance through synergistic promotion of nitrate adsorption/activation and water activation, offering an alternative platform to conventional bi‐metallic catalyst ...

Fragmentation‐Locked Polymeric Carbon Nitride Enables Global‐to‐Local Electron Allocation for Enhanced Peroxymonosulfate Activation

Small, EarlyView.
A NaI‐assisted polymeric carbon nitride photocatalyst enables visible‐light‐driven peroxymonosulfate activation through fragmentation‐locked structural and electronic regulation. Iodide‐induced ultrathin nanosheets expose abundant active sites, while sodium ions promote global‐to‐local electron allocation toward peroxymonosulfate.

Assessment of Oxidative Stress, Vitellogenin, and Human Health Risks Derived From Nile Tilapia Exposed to Metals and Metalloids in Southeastern Brazil

Environmental Toxicology, EarlyView.
ABSTRACT Urban coastal lagoons are highly vulnerable ecosystems increasingly affected by metal contamination, as well as multiple anthropogenic stressors. This study evaluated ecotoxicological and human health risks associated with chronic metal exposure in Nile tilapia (Oreochromis niloticus) from an anthropogenically impacted lagoon in southeastern ...

Cytogenotoxic Effects of Fluopyram in Allium cepa Root Cells Involving Microtubule Disruption

Environmental Toxicology, EarlyView.
ABSTRACT Fluopyram is a next‐generation fungicide widely used in agriculture; however, its persistence in soils and mobility toward aquatic systems have raised concerns regarding potential ecotoxicological risks. This study evaluated the cytogenotoxic effects of a commercial fluopyram‐based pesticide formulation on Allium cepa root meristem cells ...
