Conservation Biology, Volume 40, Issue 2, April 2026.Abstract Illegal wildlife trade (IWT) is one of the largest global illegal activities, and it negatively affects biodiversity and sustainable development worldwide. DNA barcoding coupled with high‐throughput sequencing (i.e., metabarcoding) is useful in identifying taxa affected by IWT and has been used routinely for decades.

Gaoya dianqi, 2002 现代晶闸管阀的高额定容量使其难以在试验室用背靠背试验回路进行试验,用合成试验回路对晶闸管阀的设计进行验证是一种替代方法。设计合成试验回路的核心在于,如何正确地再现作用在晶闸管阀上的负荷。为此,重点描述了换流阀在4种运行状态下的电压和电流负荷。ABBPowerSystems开发了一种新的合成试验回路,正确地再现了运行中施加在HVDC晶闸管阀上的电压和电流负荷。验证试验表明,该回路的设计是成功的。

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT NiFe‐based MIL‐55 metal‐organic frameworks (MOFs) face challenges in achieving atomically precise composition and reliable methods for uniform growth. This study addresses these challenges by applying a slow evaporation crystallization technique to crude colloidal MIL‐55 products from hydrothermal synthesis, resulting in highly uniform ...

Dianci bileiqi, 1985 用固体涂层法和盐雾法对硅橡胶护套、氟塑料护套、瓷护套合成绝缘子和标准型瓷绝缘子做人工污秽对比试验。两种试验结果相仿,但有差别。在盐雾试验中,更能显出合成绝缘子表面憎水性的作用。在实验室中,合成绝缘子有优异的耐污性能。但需要进行长期运行试验,来考验表面性能的耐久性。

Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT Achieving a simultaneous enhancement of strength and ductility remains a critical bottleneck for the large‐scale and cost‐effective engineering application of magnesium alloys. In this work, guided by first‐principles calculations, we tailored the τ‐Mg32(Al,Zn)49 phase and optimised twin boundary, thereby designing and successfully ...

Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT The high accuracy in surface‐enhanced Raman scattering‐lateral flow immunoassays (SERS–LFIAs) is critical for reliable point‐of‐care testing (POCT) in clinical diagnostics. Conventional approaches are often affected by sampling variability and uneven distribution of immunoprobes, leading to unreliable signal fluctuations.
