Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT NiTi shape memory alloys (SMAs) show excellent performance in vibration damping and corrosion resistance. However, due to low hardness and lack of self‐lubrication, they suffer severe friction and wear during service. Although various strategies including doping and heterostructure design have been proposed, the effects are unsatisfactory.

Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT Bone restoration is often hindered by the spatiotemporal dysregulation of immune and regenerative signals. Conventional bio‐inert implants, providing only passive support, fail to modulate this microenvironment, leading to infections and poor healing.

Topological uniform descent and property (WE) for bounded linear operators(有界线性算子的拓扑一致降标及(WE)性质)
Zhejiang Daxue xuebao. Lixue ban, 2023 设H为无限维复可分的Hilbert空间，B(H)为H上的有界线性算子全体。若σ(T)\σw(T)=E(T)，其中σ(T)和σw(T)分别表示算子T的谱集和Weyl谱，E(T)=λ∈iso σT:dimNT-λI>0，则称 T∈B(H)满足(WE)性质。首先通过拓扑一致降标性质，给出了有界线性算子及其函数满足(WE)性质的充要条件；然后应用所得结果讨论了Drazin可逆算子与其Drazin逆的(WE)性质之间的关系。

Dimensional Assembly Engineering of Ce‐MOF Interfaces for Selective Recognition of Phytic Acid
Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Selective molecular recognition is central to chemical sensing yet discriminating structurally similar molecules at complex interfaces remains challenging. Traditional strategies based on tuning size, charge, or binding‐site chemistry often suffer from limited flexibility.

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Lithium‐selenium (Li‐Se) batteries have attracted considerable attention due to their high theoretical specific capacity and the intrinsically good electronic conductivity of selenium. Nevertheless, low active‐material utilization, parasitic side reactions, and sluggish reaction kinetics hinder their practical application.

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Water electrolysis is a promising method for green hydrogen production, but slow hydrogen evolution reaction (HER) kinetics require efficient catalysts. In this study, we develop a Ni3S2/MoS2 heterostructure electrocatalyst using a work‐function‐driven electronic modulation strategy combined with a self‐sacrificial template approach.
