Synergistic B/Si Microalloying Induced Wear Resistance Improvement in FeCoNiCrCu High‐Entropy Alloy Coatings Prepared by Annular Oscillating Laser Deposition

open access: yesRare Metals, Volume 45, Issue 11, November 2026.
ABSTRACT To address the insufficient wear resistance of high‐entropy alloy (HEA) coatings under extreme conditions, FeCoNiCrCu and FeCoNiCrCuB0.03Si0.03 microalloyed coatings were fabricated via annular oscillating laser deposition. This work systematically investigated the effects of synergistic B/Si addition on their phase composition, microstructure,

金属多羧酸配位聚合物的合成、热化学与应用研究

open access: yes, 2012
本论文旨在合成具有新颖结构的金属多羧酸配位聚合物,根据其结构特点对其性能进行研究。并以金属多羧酸配位聚合物为前驱体制备了均匀分散的碳包覆金属纳米粒子,研究了其对金属氢化物的催化性能。 研究了溶剂热体系中含氮含氧混合配体过渡金属配位聚合物的合成和表征。选择一缩二乙醇酸(H2oda)为含氧配体,2,2’-联吡啶或4,4’-联吡啶为含氮配体,得到四种金属配位聚合物[Co2(oda)2(4,4’-bipy)]•DMF(C1)、[Cu(oda)(2,2’-bipy)]2(C2)、[{Ni(oda)(H2O)2}2(

Synergistic Electronic Modulation of 1T/2H Mixed‐Phase MoS2 via Phosphorus Insertion and Carbon Coating for Enhanced Acidic Hydrogen Evolution Kinetics

open access: yesRare Metals, Volume 45, Issue 11, November 2026.
ABSTRACT MoS2 is considered a promising electrocatalyst for the hydrogen evolution reaction (HER) because of its low cost and excellent stability. However, its practical application is severely limited by the scarcity of edge active sites and poor intrinsic electrical conductivity.

Enhanced Microwave Attenuation via Coupled Ni3ZnC0.7/Ni3InC0.5 Heterogeneous Interfaces

open access: yesRare Metals, Volume 45, Issue 11, November 2026.
ABSTRACT The growing complexity of electromagnetic environments places increasingly stringent demands on microwave absorbers, particularly regarding broadband attenuation, impedance matching in ultrathin configurations, and structural stability. Herein, we propose a dual nonstoichiometric carbide synergistic regulation strategy, in which Ni3ZnC0.7 and ...
