Anchoring Polyoxometalate (PMo11Fe) on ZnO Nanosheet for Construction of a Novel S‐Scheme Heterojunction Toward Efficient Photodegradation of Levofloxacin Antibiotics

open access: yesRare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT Currently, the photocatalytic performance of ZnO has been severely limited by its weak light response ability and sluggish charge carrier dynamics, which considerably hinder its extensive application in photocatalytic fields. Herein, through anchoring the synthesized K6PMo11FeO40·nH2O (PMo11Fe) onto ZnO nanosheets, a novel S‐scheme ...

Synchronous Ultrasonic Impact Treatment for Regulating Microstructure and Properties of Laser‐Directed Energy Deposited In Situ TiC/Ti6Al4V Composites

open access: yesRare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT In laser‐directed energy deposition (LDED) of TiC/Ti6Al4V composites, a low content of micron‐sized TiC provides a good strengthening effect on hardness and strength, but the improvement in plasticity remains a challenge. By introducing synchronous ultrasonic impact treatment (UIT) into the LDED process, an ultrasonic‐assisted LDED (UA‐LDED ...

A Strontium‐Based Polyphenol Nanozyme Reverses Cisplatin‐Related Acute Kidney Injury Through Near‐Infrared‐Enhanced PI3K/AKT Pathway Inhibition and Macrophage M2 Directional Polarization

open access: yesRare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT Cisplatin‐related acute kidney injury (CP‐AKI) is a serious complication of cisplatin (CP) treated patients with cancer with high morbidity and mortality rates. It is directly related to the abnormal accumulation of CP in renal tubular epithelial cells, causing metabolic toxicity, DNA damage, and oxidative stress.

Mesoporous Hexametallic High‐Entropy Alloy Nanotubes With Multicomponent Electronic Modulation for Efficient Bifunctional Catalysis

open access: yesRare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT Platinum‐based electrocatalysts are fundamentally constrained by strong oxygen binding, which restricts the oxygen reduction reaction (ORR) kinetics, and by severe CO poisoning, which hinders the methanol oxidation reaction (MOR). To address these limitations, we synthesized PdPtRuIrRhNi high‐entropy alloy (HEA) mesoporous nanotubes that ...

高频过电压抑制导线抑制VFTO的试验研究

open access: yesGaoya dianqi, 2019
为验证高频过电压抑制导线(以下简称抑制导线)对VFTO抑制效果,在某550 kV GIS试验平台上开展了VFTO抑制验证试验。为开展试验,依据IEC 62271?102—2013标准对试验平台的尺寸进行了优化设计。依据GIS的工作工况,设计了加交流、直流、隔离开关分闸、合闸等试验条件。从VFTO的幅值、持续时间、击穿次数和频率成分方面对安装抑制导线前后的试验结果进行了总结分析。试验结果表明:VFTO最高幅值可从安装前2.42p.u.下降为1.49p.u.;幅值抑制比最大可达52.94%,最小也有22 ...

小叶女贞叶片脲酶抑制物质的提取及抑制作用研究

open access: yes四川大学学报. 自然科学版, 2010
从小叶女贞叶片中提取分离了具有抑制脲酶作用的活性成分并对其抑制作用进行研究.结果显示该活性物质主要成分为多糖和酚类物质,对脲酶有较强的抑制作用,随着脲酶抑制物质浓度增加,抑制作用增强.加入β-巯基乙醇(2-Me)后,脲酶的活性恢复,说明该脲酶抑制物质是通过与脲酶的-SH发生作用而导致脲酶的活性降低.

Emerging High‐Entropy Electrolytes for High‐Performance Alkali Metal Batteries: Mechanism, Progress, and Prospects

open access: yesRare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT Alkali metal (Li, Na, and K) batteries (AMBs) have attracted widespread attention in recent years because of their high theoretical specific capacity and attractive energy density. However, they still suffer from uncontrollable dendrite growth and sluggish conductivity during cycling, which lead to security issues and inferior cycling ...
