ABSTRACT Background Chronic rhinosinusitis (CRS) is frequently associated with polymicrobial biofilms involving Staphylococcus aureus and Pseudomonas aeruginosa. Interactions between these organisms are thought to influence disease severity, but the epithelial effects of exoproteins derived from patient‐matched cocultures remain poorly defined ...

This study employs a hard‐templating etching strategy to synthesize N‐doped hollow mesoporous carbon spheres embedded with NiCo nanoparticles (denoted as NiCo@N‐HMCS). The optimized catalyst exhibits exceptional bifunctional catalytic activity for the oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) in alkaline media, achieving a ...

Ni:Cu (3:1) films, sputtered on nickel foam form self‐supported electrocatalysts for alkaline water splitting. The hydrogen evolution electrode (270 nm) overpotential at −50 mA cm−2 drops from 215 to 136 mV after 72 h, owning to Cu leaching . For oxygen evolution, it reaches 370 mV at 10 mA cm−2.

Electronegativity‐guided site differentiation is realized in a CoNiCuMoW high‐entropy alloy, where Co/Ni sites optimize hydrogen binding strength, Mo/W sites promote water dissociation, and Cu‐associated sites contribute to balanced hydrogen adsorption.

ABSTRACT Fe‐N‐C electrocatalysts are considered promising alternatives to platinum‐based catalysts for advancing the development of metal–air batteries. However, the simultaneous realization of scalable synthesis, hierarchical mass‐transfer pathways, and precise regulation of Fe‐N4 sites remains challenging. Different from conventional Fe‐N‐C synthesis,

Poly(lauryl methacrylate)‐poly(2‐hydroxyethyl methacrylate) (PLMA‐PHEMA) diblock copolymer nanoparticles prepared in non‐polar media serve as nanoreactors for the in situ synthesis of silica from tetraethyl orthosilicate (TEOS). A silica mass loading of 17% as judged by thermogravimetric analysis (TGA) produces a highly transparent dispersion, and ...

Dietary Niches and Their Consequences for Five Insectivorous Passerines in a Seasonal Boreal Setting
ABSTRACT To understand the effects of climate change and other disturbances on ecosystems, methodologies capable of unravelling the complexity of biotic interactions are vital. Here, we present a dietary study on five passerines nesting in boreal forests: the crested tit Lophophanes cristatus, willow tit Poecile montanus, blue tit Cyanistes caeruleus ...

Trithiocarbonates for PGM flotation
Small replacements of C-trithiocarbonate (C-TTC) for dithiocarbonate (DTC)/dithiophosphate (DTP) in a reagent suite for the flotation of platinum group metals (PGM) have significantly improved the rejection of gangue. Coupled to this is an improvement in
