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 5, May 2026.ABSTRACT The large‐scale application of titanium is limited by its high production costs, as well as its low utilization and recycling rates. Therefore, efficient recovery of titanium scrap offers a viable pathway to reduce its cost. Molten‐salt electrolysis offers a promising route for upcycling titanium scrap, but the conventional method, which ...

Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT Lightweight and lead‐free radiation shielding materials remain urgently needed. This work designed a fluorite high‐entropy oxide (FHEO) system through a combined computational–experimental route. Density functional theory based on special quasi‐random structures was used to identify thermodynamically stable fluorites from a wide compositional ...

Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT Formic acid (FA) is considered to be a safe and convenient hydrogen source; however, achieving controlled and efficient FA dehydrogenation under mild conditions using stable solid catalysts remains a significant challenge. Pd‐based catalysts have been extensively studied due to their superior catalytic activity to other metal catalysts.

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT The Schottky barrier height (SBH), which serves as a pivotal determinant of charge carrier injection efficiency in electronic devices, critically governs electrical behavior at metal/semiconductor interfaces. However, pronounced metal‐induced gap states at metal contact interfaces induce Fermi‐level pinning, which constrains the ...

Zhejiang Daxue xuebao. Lixue ban, 2008 通过蛋白质分子内两残基间距的概率分布函数P(r)，计算了641个蛋白质分子内近程和远程紧密接触对的形成速率.分析了不同蛋白质结构，不同紧密接触对半径以及DNA的绑定对速率的影响.结果表明：不同结构类型蛋白近程和远程紧密接触对的形成速率的变化趋势恰好相反.近程紧密接触对的形成速率kS随着n（n=|j—i|）的增大而增大，远程紧密接触对的形成速率kL随着n的增大而减小，并且远程紧密接触对的形成速率kL满足kL (n)∝n-γ的关系.γ值随着紧密接触对半径a的增大而变小，当a = 0.6 nm时 ...
