Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT Microstructural characterization of Li0.32La0.56Fe0.01Ti0.94Sb0.06O3 (LLFeTSO) using AC‐TEM revealed that Fe3+/Sb3+ ion co‐doping induces the migration of lattice oxygen to grain boundaries (GBs), enhancing GB conductivity. However, the atomic arrangement at the GBs remains highly ordered and lacks sufficient cation vacancy carriers.

Scientists’ warning on the global destruction of rock outcrop ecosystems
Conservation Biology, Volume 40, Issue 5, October 2026.Abstract Rock outcrops are geological formations that harbor a highly specialized biota adapted to harsh environmental conditions that differ from their surrounding landscapes. They are globally distributed, especially in old, highly weathered landscapes, and can function as habitat islands containing high levels of endemism and distinct evolutionary ...

Shiyou jixie, 2012 封隔器胶筒与套管的接触压力是衡量密封性能的重要依据。应用ANSYS有限元软件，数值模拟了封隔器坐封后的应力、应变分布及接触状态，得出胶筒的整体接触压力分布和上、中、下3个胶筒与套管接触压力的分布规律。线性回归了坐封力与接触压力的关系式。指出封隔器各胶筒与套管的最大接触压力随着坐封液压力的增大而增大，并且上、中胶筒呈线性关系，下胶筒呈二次曲线关系。

Rare Metals, Volume 45, Issue 9, September 2026.ABSTRACT Tin‐based composite oxides typically undergo severe volume variations and exhibit poor intrinsic conductivities despite their high theoretical capacity as promising anode candidates for sodium‐ion batteries. This results in rapid structural degradation and capacity fading upon cycling.

Jianzhu Gangjiegou Jinzhan, 2010 近年来,国产高性能建筑结构用钢由于其优良的力学性能,特别是强度对厚度的不敏感性,在国内大跨和高层建筑钢结构中得到了越来越多的应用,但现行相关设计规范中仍缺乏其基于设计可靠度分析的合理设计指标。高建钢常用作厚壁H型钢柱,其残余应力分布对构件承载力影响较大,是分析高建钢基本构件设计可靠度的关键因素之一。本文采用条形切割法,对80mm厚高建钢Q345GJ焊接H型钢的纵向残余应力分布进行了详细的测试试验研究。根据试验数据,得到80mm厚高建钢Q345GJ焊接H型钢残余应力分布图 ...
