Uncovering Cu Involved Nanophase Structures and Transformation in a Novel 7075B Aluminum Alloy

open access: yesRare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT In this study, aberration‐corrected transmission electron microscopy combined with first‐principles calculations was employed to systematically investigate the Cu‐involved crystal structures and evolution mechanisms of nanoprecipitates in a novel 7075B Al alloy. Firstly, an atomic model of the early‐stage GP‐ηp structure together with specific

Unveiling Entropy‐Driven Hard‐Tough Synergy Mechanisms in High‐Entropy Carbonitride Ceramics

open access: yesRare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT High‐entropy ceramics manifested promise for extreme environments, yet their phase stability and mechanical synergy mechanisms remain elusive. Herein, entropy‐difference carbonitrides, including (TaTiV)CN, (TaTiVNb)CN, and (TaTiVNbHf)CN, were designed and consolidated via spark plasma sintering.

Efficient Photocatalytic Removal of Toluene by Synergistic FeCe/TiO2: Performance and Mechanism

open access: yesRare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT Efficient removal of volatile organic compounds (VOCs) in confined spaces is crucial for environments such as spacecraft and deep‐sea submarines. Metal modification is an effective strategy to enhance the light absorption capacity of titanium dioxide (TiO2) and suppress the recombination of photogenerated charge carriers.

紫色母岩在不同酸环境中的崩解分维特征

open access: yesShuitu Baochi Xuebao, 2017
基于分形相似性原理,以遂宁组(J3s)、沙溪庙组(J2s)和蓬莱镇组(J3p)紫色母岩为研究对象,分别进行了24次不同pH溶液中的静态崩解试验。结果表明:3种紫色母岩在不同酸溶液中的崩解过程中存在一定的差异,但总体表现为溶液酸性越大,崩解越迅速。遂宁组和沙溪庙组母岩经过24次崩解循环后,各pH下崩解分维数均接近3,崩解趋于稳定,且溶液pH值越小,分形维数趋于稳定所需的循环次数越少,而此时蓬莱镇组母岩仍处于持续崩解阶段。岩石的酸化侵蚀是一个漫长的作用过程,崩解初期 ...

Revealing the Roles of Electrolyte Concentration on Transition Metal Dissolution and Reaction Pathway of Anion Adsorption Pseudocapacitance

open access: yesRare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT Conventional lithium‐ion battery cathodes predominantly rely on reversible lithium intercalation in bulk, which inevitably induces phase transitions, transition metal migration, and voltage decay. Electrolytic anion adsorption pseudocapacitance provides a chance for bypassing these issues via a surface‐dominated reaction, especially in ...

Synergetic Ruthenium Clusters and Ligand Motifs in Insoluble Polyoxometalates for Efficient Urea Electrosynthesis

open access: yesRare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT The electrocatalytic co‐reduction of CO2 and nitrate (NO3− ${\text{NO}}_{3}^{-}$) to synthesize urea presents a sustainable alternative to traditional industrial processes, yet its efficiency is fundamentally limited by the kinetically mismatched activation and coupling of CO2 and NO3− ${\text{NO}}_{3}^{-}$.
