Effects of Nitrogen and Vanadium Additions on Microstructures, Tensile and Impact Properties of a Cast Austenitic High–Manganese Steel for Cryogenic Application

This study demonstrates that adding nitrogen and vanadium to a cast austenitic high-manganese steel significantly enhances its strength, ductility, and cryogenic impact toughness through interstitial solid-solution strengthening, vanadium nitride precipitation, and twinning-induced plasticity, resulting in a notably higher stacking fault energy compared to baseline and commercial alloys.

Investigation Of Different Bio-Mordants On Cotton Dyeing With Harmal Seed Extracted Natural Dyes

This study demonstrates that citric acid, grapefruit peel extract, and banana peel extract serve as effective bio-mordants for dyeing cotton with harmal seed extract, with citric acid at 60% concentration yielding the highest color strength while all treatments achieved excellent light and rubbing fastness.

Bio-Inspired Lock-and-Key Lamellar Membranes for Selective CO2 Separation Using Confined CO2‑Philic Ionic Liquids

Inspired by the KcsA potassium channel, this study develops a bio-inspired "lock-and-key" lamellar membrane by electrostatically confining CO2-philic polyoxometalate ionic liquids within layered double hydroxide nanochannels, achieving superior CO2 separation performance that surpasses the Robeson upper bounds while overcoming the traditional permeability-selectivity trade-off.

An auditable decision framework for donor–acceptor materials screening

This paper presents an auditable decision framework that integrates multimodal predictions, uncertainty quantification, model explanations, and literature evidence to transform donor–acceptor material screening from simple property ranking into a traceable, evidence-guided prioritization process for selecting candidates for experimental validation.
