Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT The efficacy of immunotherapy in triple‐negative breast cancer (TNBC) is often limited, whereas the immunotherapeutic potential of pyroptosis is frequently undermined by a compensatory surge in mitophagy. To address this challenge, this study developed a reactive oxygen species (ROS)‐responsive and mitochondria‐targeted nanomicelle (POM@CTT ...

Jianzhu Gangjiegou Jinzhan设计制作了4个H型钢梁试件，通过拟静力试验得到不同腹板高厚比以及钢种组合下钢梁的破坏形态、滞回曲线、骨架曲线以及延性等，从而评价试件的滞回性能。随后利用有限元软件ABAQUS进行模拟验证，通过参数分析进一步补充不同腹板高厚比和钢种组合对钢梁滞回性能的影响。结果表明：随着腹板高厚比的减小，钢梁的延性和耗能能力均有所提高，且增大腹板厚度对钢梁延性的提高程度大于极限承载力的提高程度；相比同钢种钢梁，多钢种钢梁极限承载力提高了17.4%，延性降低5.6%。随着多钢种钢梁翼缘强度等级的增大 ...

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT The rapid expansion of data‐intensive applications has highlighted the fundamental limitations of traditional CMOS‐based von Neumann architectures, particularly in terms of power efficiency, latency, and flexibility. Spin logic devices utilizing spin–orbit torque (SOT) present a promising pathway for nonvolatile, low‐power, and in‐memory ...

Jianzhu Gangjiegou Jinzhan, 2019 为进一步研究装配式钢结构H形钢梁-钢管柱连接节点的力学性能,以装配式钢管柱-组合螺栓连接节点试件为研究对象,利用ANSYS有限元软件对其进行了低周往复荷载作用下的抗震性能数值模拟分析。基于数据的整理和对比,分析节点试件的破坏模式、耗能能力、承载力、延性、刚度退化等力学性能。研究结果表明:由于对穿螺栓具有将钢梁上、下翼缘轴力直传至钢管柱对面的作用,在循环往复荷载作用下,钢管柱柱壁均出现"对称凹屈"现象,随后以梁端出现塑性铰丧失承载能力而破坏;节点承载力较高且耗能能力强,等效黏滞阻尼系数平均大于0.4 ...

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Laser powder bed fusion (LPBF) can fabricate high‐entropy alloys (HEAs) with refined microstructure and enhanced mechanical properties. However, the deformation and fatigue mechanisms of Al‐containing HEAs produced by LPBF remain unclear. In this work, we systematically investigate the tensile properties, deformation mechanisms, and high‐cycle

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT The protracted incubation time has long been the Achilles' heel of the promising 2LiBH4–MgH2 hydrogen storage system. Instead of the usual route‐creating heterogeneous nucleation sites to hasten MgB2 formation, we shortened both de‐ and re‐hydrogenation incubation periods by steering the Mg transformation itself.

Jianzhu Gangjiegou Jinzhan, 2022 为了研究腹板开椭圆孔耗能支撑的滞回性能，进行了3个支撑试件的低周往复加载试验，研究支撑长细比和耗能腹板长度对这种支撑耗能能力和滞回性能的影响，得到试件的滞回曲线、骨架曲线、刚度退化曲线、延性系数、等效黏滞阻尼比等。试验结果表明：在低周往复荷载作用下，腹板开椭圆孔耗能支撑依靠腹板开孔板件进入塑性耗散能量。耗能支撑滞回曲线饱满，耗能能力强，初始刚度较高。孔间板件断裂破坏导致耗能支撑试件失效，试件呈现延性破坏。试验过程中，中部工字钢保持弹性状态，没有进入塑性。相同长细比下耗能腹板的长度越长 ...

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Refractory complex‐concentrated alloys (RCCAs) show exceptional promise for extreme‐environment applications, yet intermediate‐temperature instability (0.4–0.6 Tm) and plasticity degradation severely constrain their development. This work provides an effective strategy to transform the inherent intermediate‐temperature instability into a ...
