This work develops melt-extracted (FeCoNi)₈₀B₂₀ medium-entropy amorphous alloy fibers to integrate overall water splitting with advanced oxidation for wastewater treatment. The crystalline–amorphous heterostructure and multielement synergy regulate OH* adsorption, balancing electrocatalytic activity and pollutant degradation. In simulated reclaimed water, the coupled process achieves complete decolorization within 60 min and 63.24% total organic carbon removal, while an anion-exchange membrane electrolyzer operates at 200 mA cm⁻² for approximately 100 h. Production in approximately 100 g batches further highlights its potential for coupling hydrogen production with water remediation.

This work constructs hierarchical sea urchin-like yolk–shell CoNi@N-doped carbon-CoNi@CNTs nanocomposites using Prussian blue analogue precursors and catalytic chemical vapor deposition. Integrating CoNi nanoparticles, carbon nanocubes, and CNTs creates abundant polarization interfaces and conductive pathways, improving impedance matching and microwave attenuation. The composites achieve a minimum reflection loss of −71.70 dB at a thickness of 2.78 mm and an antibacterial rate of 84.03% against E. coli at 1 mg mL⁻¹. Their additional photothermal conversion, hydrophobicity, and corrosion resistance highlight a strategy for multifunctional microwave absorbers suited to complex environments.

Boosting Oxygen Evolution Reaction Performance on NiFe-Based Catalysts Through d-Orbital Hybridization
Xing Wang, Wei Pi, Sheng Hu, Haifeng Bao*, Na Yao*, Wei Luo*
Nano-Micro Lett. (2025) 17:11
https://t.co/2SnNKu5C2o

This work develops La-modified NiFe catalysts with 3d–5d orbital coupling to enhance oxygen evolution reaction activity and stability. Experimental and theoretical analyses reveal that La incorporation breaks the symmetry of Ni–Fe units, optimizes metal–oxygen orbital hybridization, strengthens oxygen-intermediate adsorption, and lowers the rate-determining step energy barrier. The NiFeLa catalyst requires an overpotential of only 190 mV at 10 mA cm⁻² in 1 M KOH. An anion-exchange membrane water electrolyzer achieves 1.58 V at 1 A cm⁻² at 80 °C, with durability demonstrated for over 600 h at 1 A cm⁻².

The authors establish a carrier‑behavior‑driven framework to correlate high‑injection recombination, interfacial carrier crowding and efficiency roll‑off for perovskite light‑emitting diodes (PeLEDs). Taking self‑assembled monolayers as representative molecules, this review systematically dissects how interfacial molecules tune charge balance, suppress interfacial non‑radiative recombination, tailor local electronic structure and regulate bottom‑interface crystallization. The authors further distill practical molecular design guidelines, highlighting bias‑resistant electronic modulation, persistent defect passivation and structural compatibility with emissive layers. By bridging carrier‑level photophysics, interfacial functions and molecular regulation, this work offers mechanistic insights and clear design strategies toward high‑efficiency and stable PeLEDs.

The authors propose a bifunctional MPTMS coating strategy via mechanochemical ball‑milling to address the notorious moisture‑sensitivity issue of argyrodite‑type sulfide solid electrolytes. The synergy of covalent S‑S bonding and hydrophobic siloxane network greatly suppresses toxic H₂S release while retaining high ionic conductivity. Systematic characterizations verify improved air stability, inhibited hydrolysis‑oxidation degradation and enhanced cathode interfacial compatibility. Assembled all‑solid‑state cells and pouch cells deliver outstanding long‑cycle performance. This scalable surface‑modification approach is also applicable to other thiophosphate electrolytes, paving the way for ambient‑atmosphere manufacturing of practical all‑solid‑state lithium batteries.
