Surface Engineering of Ti3C2Tx MXenes via Silanol Functionalization for Improved Electrochemical Performance

open access: yesSmall, EarlyView.
This study explores the covalent functionalization of Ti3C2Tx using 5,5′‐bis(triisopropoxysilyl)‐2,2′‐bipyridine in different solvents, revealing that only m‐xylene enables effective covalent bonding, ensuring structural stability and preventing layer swelling.

Tuning Optoelectronic Properties and Photoelectrochemical Performance of β‐TaON via Vanadium Doping

open access: yesSmall, EarlyView.
Vanadium‐doped β‐TaON is studied to elucidate how controlled cation substitution modulates crystal and electronic structures and photoelectrochemical performance. Moderate vanadium incorporation (<10 at.%) retains phase purity, narrows the bandgap, and improves charge transport, whereas excessive doping (>10 at.%) induces secondary phases that suppress

Pure Chitosan Microfluidic Spinning Affords Modular Core‐Sheath Fibers and Hand‐Crafted Scaffolds with Enhanced Fibroblast Compatibility

open access: yesSmall, EarlyView.
Microfluidic Wet Spinning affords highly resilient and biocompatible microfibers of pure chitosan without the use of any crosslinker. We produced microfibers both sheath and core of made of chitosan and another version with a chitosan sheath and chitin nanocrystals in the core.

Exploration of Copper Halide Linear‐Array Detector Prototype for Security Checks

open access: yesSmall, EarlyView.
Mn‐doped Cs3Cu2I5 is demonstrated as a highly promising scintillator for X‐ray imaging, featuring high light yield, a low detection limit, and negligible afterglow. A linear‐array detector prototype based on the Mn‐doped Cs3Cu2I5 delivers a spatial resolution of 1.1 lp/mm in food‐safety and security inspections, marking a significant advance in the ...

Outline of a Washing Treatment to Improve Electric Arc Furnace Slag Environmental Behavior

open access: yessteel research international, EarlyView.
This study evaluates a water‐washing treatment for electric arc furnace slag to reduce the leaching of hazardous elements (Cr, Ba, Mo, and V), enabling its reuse. The process effectively decreases leachate concentrations. Using the treated slag as a substitute aggregate in concrete reduces greenhouse gases emissions by 42.5% compared to landfilling ...
