Comprehensive framework for assessing and optimizing existing research networks
Conservation Biology, EarlyView.Abstract Conservation, monitoring, and research networks, or collections of ecological research sites unified under a common mission of data collection or a research mission, are essential infrastructure for understanding large landscapes. However, most networks developed opportunistically over decades rather than through systematic design, creating ...

Conservation Biology, EarlyView.Abstract Modeling species distributions in dynamic pelagic environments remains challenging, particularly for wide‐ranging and highly mobile species when there is limited guidance on model performance. This limitation constrains the effective use of species distribution models (SDMs) in marine conservation, where robust and transferable predictions are

Methodology to identify ecologically matching areas and its applications in conservation planning
Conservation Biology, EarlyView.Abstract Identifying ecologically matching areas is both challenging and critical for understanding spatial patterns of biodiversity and advancing conservation planning. However, existing approaches often lack spatial flexibility, overlook shape and size constraints, or rely on limited environmental parameters, reducing their effectiveness in real ...

Grain Boundary Density Governs the Discharge Behavior of Mg Anodes in Biodegradable Batteries
Rare Metals, Volume 45, Issue 11, November 2026.ABSTRACT Biodegradable magnesium (Mg) alloys have entered clinical use, yet their development as self‐powered absorbable batteries is hindered by poor anode performance, including high self‐corrosion, passivation, and nonuniform dissolution. The role of grain boundary density in governing discharge behavior remains unclear.

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT Microstructural characterization of Li0.32La0.56Fe0.01Ti0.94Sb0.06O3 (LLFeTSO) using AC‐TEM revealed that Fe3+/Sb3+ ion co‐doping induces the migration of lattice oxygen to grain boundaries (GBs), enhancing GB conductivity. However, the atomic arrangement at the GBs remains highly ordered and lacks sufficient cation vacancy carriers.

Conservation Biology, Volume 40, Issue 5, October 2026.Abstract Ecological niche models (ENMs) are used to assess the abiotic preferences of species by linking their occurrences to the environmental conditions in which they live. We developed a fossil‐informed ENM framework that integrates mid‐Holocene and modern occurrences to test niche stability and reconstruct abiotic niche characteristics for four ...

Integrative Conservation, Volume 5, Issue 3, Page 255-267, September 2026.This study presents a comprehensive review of the 500‐year spatiotemporal evolution of global botanical gardens, identifying three major development stages—initial exploration (1543–1699), steady expansion (1700–1899), and rapid proliferation (1900–2020)—with six distinct sub‐stages. We propose a tripartite driving framework grounded in colonial botany

Dianci bileiqi, 2023 针对目前风力发电机叶尖附近空间电荷的分布特性不明确等问题，笔者利用仿真建模手段对风机叶片处于不同旋转角度时叶尖电晕放电进行了仿真研究，将风机叶片旋转时叶尖与周围空气的相对运动等效为叶尖流过的高速气流，考虑正极性离子与其他离子的附着与碰撞作用，建立了一种二维正极性电晕放电空间电荷分布模型；基于上述模型，得到了风机叶片旋转到不同角度时叶尖电晕放电正极性空间电荷的分布特性和以及正离子迁移规律。研究发现，在雷云电场作用下，由于风机叶片旋转时叶尖流过的高速气流提供给空间电荷的迁移速度远大于电场牵引力提供的迁移速度，

Electrically Switchable Altermagnetism in Monolayer MoCl3
Rare Metals, Volume 45, Issue 9, September 2026.ABSTRACT Altermagnets intertwine spin‐split bands with vanishing net magnetization, offering great potential for high‐density, stray‐field‐free spintronic devices. However, their development is hindered by both material scarcity and difficulties in external control due to their intrinsic symmetry protection.

Rare Metals, Volume 45, Issue 9, September 2026.ABSTRACT An ultra‐high as‐deposited tensile strength of 1408 MPa—the highest reported value for laser‐directed energy deposition (L‐DED) fabricated Ti2AlNb alloy—is achieved in this study. The as‐deposited microstructure consists of coarse B2 grains with a high density of fine acicular O phase precipitates within the grains, along with a brittle α2 ...
