High-pressure behaviour of REE-free calcioburbankite structure

This study investigates the high-pressure behavior of REE-free calcioburbankite up to ~20 GPa using in situ single-crystal X-ray diffraction, revealing its stability, pronounced compressional anisotropy, and structural deformation mechanisms to provide essential elastic constraints for modeling burbankite-group minerals under mantle conditions.

Multielement coordination regulates Co sites in high-entropy oxides for selective peroxymonosulfate activation

This study demonstrates that multielement coordination in a Co-Fe-Mn-Ni-Cu high-entropy oxide creates a specific Mn-Co dual-site environment that optimizes Co valence states to selectively activate peroxymonosulfate via a singlet oxygen-dominated pathway, achieving significantly enhanced and stable degradation of sulfamethoxazole compared to conventional cobalt oxides.

Effect of La on the structure, selectivity and stability of La/Co 3 O 4 catalysts in preferential oxidation of carbon monoxide in hydrogen-rich streams

The study demonstrates that incorporating 1 wt.% lanthanum into Co₃O₄ via incipient wetness impregnation enhances the catalyst's low-temperature preferential oxidation of CO in hydrogen-rich streams by creating La-O-Co linkages and oxygen vacancies, although its performance is moderately reduced by moisture and CO₂.

Phase Evolution and Selective Barium Titanate Localization in Poly(vinylidene fluoride) and Epoxidized Natural Rubber Blends with Tunable Mechanical and Dielectric Properties

This study investigates non-vulcanized PVDF/ENR-50 blends with tunable mechanical and dielectric properties, revealing that phase inversion boundaries dictate morphology and performance while barium titanate particles selectively segregate into the ENR-50 phase, enlarging its domains without disrupting PVDF continuity.

Effect of Particle Size and Process Intensification Techniques on Cellulose Recovery from Groundnut Processing Industry Waste

This study demonstrates that groundnut shells can be effectively converted into high-quality cellulose with properties comparable to commercial standards by optimizing particle size to 450 µm and employing ultrasound pretreatment, which enhances yield, purity, and structural integrity through efficient delignification.

Mechanistic Insights into Photocatalytic Proximity Labeling and Discovery of a Novel Photocatalyst for Interactome Profiling

This study establishes a standardized framework using site-specific antibody–photocatalyst conjugates to elucidate the mechanisms of photocatalytic proximity labeling and identifies BODIPY-FL as a novel, efficient photocatalyst that enables reduced-oxidation, spatially resolved interactome profiling in both cell-surface and intracellular environments.

Green Synthesis, Characterisation and Antimicrobial Evaluation of Copper Oxide Nanoparticles Using Carica papaya Leaf Extract

This study demonstrates the eco-friendly synthesis of stable, crystalline copper oxide nanoparticles (35–45 nm) using Carica papaya leaf extract as a dual reducing and capping agent, which exhibit effective, concentration-dependent antibacterial activity against Escherichia coli and Staphylococcus aureus.
