Engineering 1T‐MoS2‐Integrated Bimetallic Sulfide Heterostructure on Nickel Foam for Enhanced Alkaline Water/Seawater Splitting

open access: yesRare Metals, Volume 45, Issue 11, November 2026.
ABSTRACT The heterostructured 1T‐MoS2‐based bimetallic sulfides are promising bifunctional electrocatalysts for alkaline overall water splitting. However, the controllable synthesis of these catalysts is hindered by the ready conversion of Mo species to 2H‐MoS2 and the tedious heterostructure engineering during sulfidation.

Defect‐Regulated Precipitation Enables Ultrahigh Strength‐Ductility Synergy in a FeCoCrNi‐Based High‐Entropy Alloy

open access: yesRare Metals, Volume 45, Issue 11, November 2026.
ABSTRACT A thermomechanical strategy based on rolling‐annealing cyclic (RAC) was developed to regulate defect architecture and precipitation behavior in a (FeCoCrNi)94Al3Ti3 high‐entropy alloy. Intermediate annealing during rolling enables progressive grain refinement and introduces a high density of twins, stacking faults, and dislocations, forming a ...

Dual‐Regulation of Continuous and Discontinuous Precipitation via Carbon Alloying for Enhanced Strength‐Ductility Synergy in a Medium‐Entropy Alloy

open access: yesRare Metals, Volume 45, Issue 11, November 2026.
ABSTRACT The exceptional ductility of face‐centered cubic high/medium‐entropy alloys (H/MEAs) is counterbalanced by intrinsically restrained yield strength, fundamentally compromising their application in structural and functional materials. Here, a novel carbon (C)‐driven precipitation strategy is introduced to promote discontinuous precipitation (DP)

Construction of Hydrophilic Percolation Networks in Physical Wet‐Mixed Carbon Electrodes for High‐Rate Capacitive Deionization

open access: yesRare Metals, Volume 45, Issue 11, November 2026.
ABSTRACT Capacitive deionization (CDI) using activated carbon (AC) electrodes holds great promise for seawater desalination, yet its practical application is severely constrained by the intrinsic hydrophobicity of carbon surfaces. Herein, we propose a solid‐state superhydrophilic modulation strategy that physically wet‐mixes superhydrophilic MOF ...
