Constructing Serrated Boride Composite Layer for Enhancing Wear Resistance of Ti6Al4V Alloy

Rare Metals, Volume 45, Issue 1, January 2026.
ABSTRACT Appropriate configuration combined with strong interface bonding is the essential requirement for developing high wear‐resistant coatings. Herein, based on the powder‐pack boriding process, the properties of Ti6Al4V alloy are effectively improved by constructing a serrate tribological boride composite layer.

In Situ Tailoring of FCC Ductile Phases for High‐Strength Wear‐Resistant Crack‐Free W‐Based Metallic Coatings

Rare Metals, Volume 45, Issue 1, January 2026.
ABSTRACT Tungsten is inherently brittle and particularly prone to thermal stress concentration and crack formation during additive manufacturing processes such as laser cladding, which severely limits its engineering applications as a coating material. To address this issue, this study proposes an in situ toughening strategy involving the introduction ...

A novel approach for feline sporotrichosis pathogen detection based on loop‐mediated isothermal amplification

Veterinary Dermatology, Volume 36, Issue 4, Page 474-484, August 2025.
Background – Sporotrichosis is a chronic, mycotic infection caused by fungi of the genus Sporothrix. Zoonotic sporotrichosis occurs mainly through S. brasiliensis transmission, resulting from the organism's traumatic introduction via scratches or bites, or contact with exudate from contaminated cats.

Complementing urban agriculture and green spaces is important for ecosystem functions and biodiversity in cities: A systematic review and meta‐analysis

Ecological Solutions and Evidence, Volume 6, Issue 3, July–September 2025.
Urban agriculture is in an intermediate state between traditional urban green spaces and conventional rural farms in terms of environmental impacts, so that its contribution to urban sustainability requires complementarity with other green spaces. Abstract As cities expand, they encroach on agricultural land, impacting food production and natural ...

Effectiveness of protected areas in the Caucasus Mountains in preventing rangeland degradation

Conservation Biology, Volume 39, Issue 3, June 2025.
Abstract As land use intensifies globally, it increasingly exerts pressure on protected areas. Despite open, nonforested landscapes comprising up to 40% of protected areas globally, assessments have predominately focused on forests, overlooking the major pressures on rangelands from livestock overgrazing and land conversion.

PCR 和分离培养检测细胞培养支原体污染的比较

Zhongshan Daxue xuebao. Yixue kexue ban, 1999
目的: 检测细胞培养中支原体的污染, 建立支原体通用的 PCR 方法。方法: 根据已出版的序列设计并合成一对 支原体(柔膜体纲) 16S rRNA 基因组特异引物。对实验室所存的12 种支原体、大肠杆菌、变形杆菌及无支原体污染的组织培养 细胞进行了 PCR 扩增。以 PCR 与分离培养比较检测了 33份细胞培养标本。结果: 12种支原体均出现了约 620 bp左右的特异 性扩增带,敏感性为 100～ 1 000个支原体细胞, 且常见的 6种细胞培养污染支原体的扩增片段均能被 H indⅢ切成 280 与
