, 1979 近年来,研究工作者越来越重视岩石在静态和动态条件下基本力学性质的研究。其主要原因是,人们已经认识到与岩石有关的许多实际工程力学问题的解决,都有赖于弄清岩石的破坏机理、破坏准则、模型以及本构关系的建立。而研究这样一些岩石的力学性状,又必须研究岩石在各种围压、温度、应变速率等条件(即各种应力场与温度场)下的力学效应。 本文综合评述在这一领域中 ...

Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT In electrocatalysis, traditional single‐atom catalysts (SACs) face challenges in achieving coordinated control of reaction pathways due to limitations such as single local energy levels and carrier recombination. By introducing an additional defect structure, it is possible to break the electronic structure symmetry, thereby activating SACs ...

Mechanoluminescent Mixed‐Anion Borate Sr2B5O9Cl:Eu for Dynamic Anticounterfeiting
Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT Mechanoluminescence (ML)—the emission of light in response to mechanical stimuli—offers a direct and visually intuitive route for transducing mechanical information into optical signals. Herein, we report a mixed‐anion strategy to prepare mixed‐anion borate Sr2B5O9Cl:Eu phosphors through a facile, low‐temperature, and ambient‐atmosphere solid ...
