Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT In conventional photoconductive detectors, the shared collection path for dark current and photocurrent imposes a fundamental compromise between noise suppression and signal responsivity. To break this trade‐off, we introduce a device architecture featuring a strategically integrated third electrode within a MAPbI3/Nb2CTx heterostructure. This

Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT Heteroatom coordination regulation is an effective strategy to enhance Fenton‐like catalysis of single atom catalysts, yet its impact on the local microenvironment of active sites still requires in‐depth investigation. Herein, Cl2–Fe–NC catalysts with axial Cl coordination are prepared.

, 2014 通过为期2 a(2011～2012年)对黑龙江七星河国家级自然保护区白琵鹭(Platalea leucorodia)繁殖生境调查和分析,结果认为在七星河保护区白琵鹭主要选择芦苇湿地作为繁殖营巢地; 主成分分析其生境选择的决定因子是植被高度、密度、直径和水深,其贡献率分别为43.6%、18.5%、15.7%、13.4%,累计贡献率超过92%以上,其中生境选择与植被高度、密度呈正相关,与植被直径呈负相关,即白琵鹭倾向于选择植被高度高、密度大且植被直径细的芦苇湿地营巢繁殖 ...

基于InVEST模型的乌江流域生境质量时空演变及其驱动因素分析
Shuitu Baochi Xuebao目的探讨乌江流域贵州段长时间序列下生境质量的时空变化，为区域绿色化高质量发展提供理论参考。方法以1990年、2000年、2010年、2020年4期土地利用数据为主，通过移动窗口法、InVEST模型和地理探测器对乌江流域贵州段景观格局与生境质量进行计算和驱动因素分析。结果1）1990—2020年，景观格局在上游南部距干流30 km以内区域破碎度和斑块形状复杂度加深，斑块优势度和景观连通性降低；在中游南部距干流30~60 km处景观破碎度和斑块形状复杂度减弱，景观连通性增强。2）生境质量多年平均值为0.67，
