Guangtongxin yanjiu, 2012 光纤紧套被覆层剥离力是体现产品质量的一项重要指标。由于前期缺乏试验数据的积累,在相关标准中未对这一指标做出明确规定。文章对光纤紧套层剥离力进行了试验性研究,试验发现由于紧套光纤的被覆层较厚,易出现"塞积"效应。"塞积"效应对判断紧套光纤剥离力的大小有重要的影响,而它本身与试验时的刀具移动距离、移动速率及总剥离长度等因素有关,这些结论对科学规范紧套层剥离力的有效范围提供了重要的科学试验依据,同时可作为开展下一步研究工作的基础。

Oxidation Performance of NiCoCrAlYTa + 7YSZ Coatings With Ta Addition at Different Temperatures
Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT This study investigates the morphology and oxidation behavior of thermally grown oxides (TGO) formed at the interface of NiCoCrAlYTa + 7YSZ (7 wt% Y2O3‐stabilized zirconia) coatings deposited by air plasma spray (APS) in air environments at 1050°C, 1100°C, and 1150°C. The enrichment of Ta‐rich oxides beneath the TGO, along with the segregation

Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT Lithium metal batteries (LMBs) promise ultrahigh energy density, yet their advancement is impeded by dendritic lithium growth and unstable interfacial behavior. Herein, for the first time, we present novel lithiophilic CoNiB quantum dots embedded in nitrogen‐doped hollow carbon nanorods (CoNiB@NC) as a multifunctional interlayer on a ...

Gongye shui chuli, 2003 从黏泥剥离剂直接作用结果入手,建立了重量法评价方法。初步探讨了重量法的干燥条件以及黏泥致密性不一致影响因素的消除,考察了重量法评价结果的合理性和可重复性。实验表明,黏泥处于水饱和状态下直接称重的操作比较合理;采用流速冲刷可以消除黏泥致密性不一致对评价结果产生的负影响;重量法能够合理地评价出同一药剂的剥离效果随浓度变化的趋势,也能够客观地评价出不同药剂剥离效果的优劣;同一条件下,进行8次实验,重量法评价结果的相对标准偏差为8.04%。

Adaptive Chemical Strain Boundary in Freestanding BiSmFe2O6 Double‐Perovskite Membranes
Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT Double‐perovskite multiferroic systems have attracted increasing attention due to their highly tunable structures and chemical adaptability. The uncontrollable performance changes caused by the release of boundary conditions are an important factor hindering the development of freestanding membranes.

Wildlife Letters, Volume 3, Issue 4, Page 143-151, December 2025.Effects of methylmercury bioaccumulation on survival of Columbia Spotted Frogs were modified by sex and length and were mediated by corticosterone (a glucocorticoid hormone) whereas effects of chytrid fungus were limited. ABSTRACT Amphibians have suffered widespread declines caused by many interacting factors whose effects are often difficult to ...

Laser‐guided thin‐film self‐rolling for asymmetric small‐scale swimmers
Rare Metals, Volume 44, Issue 8, Page 5607-5620, August 2025.Graphical abstract AbstractSmall‐scale robots are promising miniaturized devices in biomedicine. Thin‐film self‐assembly is a commonly used strategy to fabricate tubular small‐scale robots. However, the existing methods have limitations like complex manufacturing processes and limited control of self‐assembly behavior.
