Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT The regeneration of osteoporotic bone defects is severely hampered by compromised endogenous healing capacity, demanding advanced strategies that actively orchestrate pro‐osteogenic microenvironments. Here, we report an integrated, self‐powered osteo‐regenerative system that uniquely leverages a dual ultrasound‐responsive piezoelectric ...

Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT Ultrathin, lightweight, and mechanically compliant electromagnetic interference (EMI) shields are increasingly required for high‐frequency electronic devices. However, conventional metallic shields predominantly rely on conductivity‐driven reflection mechanisms, which become ineffective at reduced thickness and may cause severe secondary ...

Gongye shui chuli, 1981 用XPS和低能离子剥蚀技术研究了TS—102予膜剂在碳钢表面予膜的组分层次,以及它们和溶液pH值、予膜时间及予膜温度之间的关联。常温下,pH6—7,予膜时间超过60小时,这时候的予膜比较厚。随着予膜时间的延长,膜中铁含量减少,铁含量最少达20％左右。予膜温度高,锌和钙的聚磷酸盐相比,钙的聚磷酸盐增加。常温下予膜,锌的聚磷酸盐始终是主要成份,这时候的予膜组分大致分为四个层次。最后用电化学原理初步说明了成膜和膜的抗腐蚀机理。

Electron‐Donating Multifunctional Molecules: A Strategy for High‐Performance Perovskite Solar Cells
Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT Multifunctional molecules containing electron‐donating groups are critically important in perovskite solar cells (PSCs), including defect passivation, crystallization modulation, energy level alignment, and other functions. This review systematically examines the application and research progress of such multifunctional molecules in PSCs ...

Flexible, Robust Transparent Conductive Films With Excellent Electromagnetic Shielding Properties
Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT Transparent conductive films (TCFs) are indispensable components for next‐generation wearable electronics, intelligent robots, and electromagnetic interference (EMI) shielding devices. However, the fabrication of conventional random metallic mesh suffers from an inherent trade‐off between “randomness and controllability”.

Gongye shui chuli, 2003 通过不同清洗方法对膜通量恢复效果的评价以及对污染膜和各步清洗后对膜表面和断面形貌的观察,对膜生物反应器工艺中的膜污染特征和膜污染进行了研究。结果表明,清水冲洗能消除纤维膜之间淤积的污泥和膜表面松散的污染层,次氯酸钠可以清除膜表面的微生物和有机污染物,而硫酸和柠檬酸能清除膜上的无机物垢。在膜外表面的污染物主要为生物膜和凝胶层污染,而膜内表面的污染物主要为滋生的微生物和无机污染物。对应各步清洗后膜通量的恢复,可以推出,在试验的工艺条件下,无机物污染对膜过滤阻力的影响较大。在此基础上 ...
