Rare Metals, Volume 45, Issue 9, September 2026.ABSTRACT Photocatalysis has emerged as a promising approach for solar energy conversion and environmental remediation. However, its practical implementation is still hindered by limited charge‐separation efficiency, slow surface reaction kinetics, and insufficient catalyst stability.

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

Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT Na‐superionic‐conductor‐type (NASICON) Na4MnV(PO4)3 (NMVP) is an appealing cathode for sodium‐ion batteries (SIBs), but its application is hindered by Jahn–Teller distortions, sluggish Na+ kinetics and poor conductivity, leading to rapid capacity fade.

Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT Most high‐entropy alloys (HEAs) tailored for contaminant degradation suffer from complex fabrication processes and high‐cost alloy design. Furthermore, low‐cost active elements such as Fe and Mg cannot be readily alloyed into HEAs via conventional routes.

Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT High‐entropy oxides (HEOs) are promising for microwave absorption but suffer from a trade‐off between impedance matching and attenuation, often requiring high filling ratios (> 50 wt%). Herein, we propose a “lattice‐spin” dual‐regulation strategy by introducing giant‐radius Bi into a single‐phase HEO solid solution.

Dianci bileiqi, 2017 考虑大气电场仪安装的位置周围有建筑物存在,而建筑物对大气电场具有一定的畸变效应,采用有限差分方法对建筑物大气电场的畸变效应进行研究。通过对建筑物的高度、宽度、电场仪与建筑物之间的距离以及安装在建筑物群之间时,建筑物对电场仪的大气电场畸变效应的数值模拟,并求出畸变系数,再用于对大气电场仪的实际测量值进行修订。本文的研究结论,能够有效地对大气电场仪的修订以及对雷暴监测预警工作的开展提供一些思路。

Atom Probe Tomography‐Based Analysis of Residual Trace Elements in Advanced Metallic Materials
Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT Residual trace elements inherited from raw materials strongly influence the mechanical and environmental performance of advanced metallic alloys and recycling materials due to preferable boundary/interface segregation and resultant embrittlement effects, yet their parts per million level concentrations pose significant challenges to ...

, 2015 采用图画-词汇干扰实验范式,考察了汉语口语产生过程中词频与音节频率效应、语音促进效应的认知年老化现象及其认知机制。结果发现,老年组的图画命名时间长于青年组,且老年组的词频效应和音节频率效应高于青年组,而语音相关效应低于青年组。老年组中词频和音节频率存在两因素交互作用,青年组则没有,这表明随着年龄增加,老年人的心理词典中不仅语义水平和音韵水平之间的联结强度变弱,而且信息之间的作用模式发生了变化。研究结果为激活不充分假设或传输不足假设提供了证据。
