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”.

Conservation Biology, Volume 40, Issue 2, April 2026.Abstract Measuring area‐based conservation outcomes in tropical forests is challenging due to cryptic human disturbances (e.g., hunting). As a result, comparative studies of management strategies providing quantitative outcomes remain scarce, especially in the Neotropics.

Integrative Conservation, Volume 5, Issue 1, Page 10-15, March 2026.First confirmed breeding of the Brown Hornbill in China, documented through cooperative feeding in Shangyong Protected Area. ABSTRACT The Brown Hornbill (Anorrhinus austeni), a Near Threatened frugivore, reaches the northern edge of its distribution in southern Yunnan, China, yet breeding had not been previously documented with site‐attributed nests in

Integrative Conservation, Volume 5, Issue 1, Page 125-136, March 2026.We collated detections of the sun bear from new and previously published camera trap studies across its range. We then analysed these detections at two different spatial scales to assess the habitat associations and diel activity of this species. We found that the sun bear is tolerant to moderate habitat disturbances. ABSTRACT Degraded tropical forests,

Gaoya dianqi, 2021 一二次融合开关是智能配电网建设的关键设备,其二次控制回路(FTU)安装在一次设备附近,处于电磁干扰环境中,但目前研究指出现行标准中的电磁兼容要求与实际电磁环境不符,在设备的运行中存在二次侧控制回路受电磁干扰严重的问题。为推动一二次融合设备试验标准化的改进,文中针对一二次融合设备电磁干扰抗扰度性能提出一种基于球隙放电的模拟电磁干扰试验方法,搭建试验平台开展一二次融合柱上开关传导干扰抗扰度试验并对互感器传递特性进行了分析。该方法可用于模拟系统中开关操作、击穿放电等工况中产生的放电干扰信号,可产生频率在1 ...

Integrative Conservation, Volume 4, Issue 4, Page 641-651, December 2025.Key Largo woodrats are a small and endangered island species, whose individuals tend to occur in family groups. Isolation from mainland populations, predation, and habitat fragmentation have caused genetic drift, leading to low overall diversity. Here, we found that a major category 4 hurricane promoted genetic diversity in the Key Largo woodrat ...

Conservation Biology, Volume 39, Issue 6, December 2025.Abstract As nations seek to expand protected area (PA) networks to cover 30% of land and seas by 2030 (30×30), there is an urgent need for systematic conservation planning and spatial prioritization that considers the broad range of ecological and socioeconomic factors influencing the persistence of biodiversity.
