Life Stage‐Specific Genetic Diversity and Landscape Characteristics Collectively Influence Genetic Recovery in Pometia pinnata Population 生活史阶段特异的遗传多样性与景观特征对番龙眼种群遗传恢复的协同影响

open access: yesIntegrative Conservation, EarlyView.
Pometia pinnata demonstrated life‐stage‐specific genetic responses to landscape features, with asymmetric gene flow patterns and population recovery following historical bottlenecks, revealing complex topographic and demographic influences on forest genetic structure.

Assessing the integration of social marketing principles in ivory demand management interventions in China and Southeast Asia

open access: yesConservation Biology, EarlyView.
Abstract Consumer demand for ivory perpetuates the unsustainable and illegal killing of African elephants and other wildlife species. Interventions that aim to change consumer behavior are increasingly recognized as a crucial element of demand management. However, poor design and implementation have limited their effectiveness.

Biodiversity‐driven spatial conservation planning to delineate temporally stable regions

open access: yesConservation Biology, EarlyView.
Abstract The accelerating loss of biodiversity underscores the critical need for effective conservation strategies, particularly in the face of climate change and anthropogenic pressures. We devised a conservation planning framework that adopts a temporal stacking approach to species distribution models and landscape connectivity analyses. These models

Scientists in power plays: How substantive were scientists' narratives during the COVID‐19 pandemic?

open access: yesPolicy Studies Journal, EarlyView.
Abstract Scientists who provide expert advice must engage with policy processes. Little is known about whether and how scientists deal with the political dynamics of policy processes that are inherent to policymaking. We study this question by building on the policy dimension concept within the Narrative Policy Framework.

Structural lobbying power? An exploration of patterns in preference attainment at varying levels of lobbying activity

open access: yesPolicy Studies Journal, EarlyView.
Abstract Studies of lobbying typically look at the extent to which interest groups realize political goals on issues they actively lobby for. Little is known, however, about the extent to which interest groups attain their political goals without making an active lobbying effort.

From Douyin Shop to TikTok Shop: The Platformized Supply Chain, Spatialized Business Model, and Regional Partnership in Cross‐Border e‐Commerce

open access: yesPolicy &Internet, Volume 18, Issue 1, March 2026.
ABSTRACT This article investigates how TikTok Shop reproduces the e‐commerce model of Douyin Shop against a backdrop of divergent regulatory challenges and geopolitical distrust. One of the strategic changes we observe in TikTok Shop is the shift of consumer goods suppliers from local merchants to China‐based sellers.

Oxygen Vacancy Engineering of Ultrafine ZnAl2O4 Nanoparticles as a Robust Protective Layer for Dendrite‐Free and Long‐Lifespan Aqueous Zn Metal Anodes

open access: yesRare Metals, Volume 45, Issue 3, March 2026.
ABSTRACT Aqueous zinc‐ion batteries (AZIBs) hold great promise for safe and sustainable energy storage, but their commercialization is impeded by severe Zn dendrite growth and interfacial instability. To address these challenges, we propose a defect engineering strategy employing ultrafine ZnAl2O4 (ZAO) nanoparticles (∼5 nm) with oxygen vacancy defects

高通流能力电阻片的研究进展

open access: yesDianci bileiqi, 2004
综述了近年来国内外在提高氧化锌电阻片通流能力方面的研究进展。认为影响氧化锌电阻片通流能力的关键因素是电阻片微观结构不均匀性导致电流分布的不均匀性。通过采用湿式化学粉料制备法来提高粉料的均匀性是提高电阻片通流能力的有效途径。而改善粉料的均匀性,从根本上讲是改善添加剂在粉料中的分散均匀性。因此,添加剂在粉料中应尽可能地细化和均匀。

藏东南高寒土坡面细沟水流输沙能力变化特征

open access: yesShuitu Baochi Xuebao, 2021
为探究高寒土坡面细沟侵蚀过程机理,建立科学的坡面细沟输沙能力因子模型,服务高寒坡面水土流失治理工作,以藏东南高寒土壤为研究对象,采用室内径流放水冲刷试验,探讨不同流量和坡度条件下细沟水流输沙能力特征。结果表明:(1)高寒土坡面细沟水流输沙能力的临界坡长随输沙能力的增加而变短,范围为3.27~8.31 m;坡度在15°~25°时,临界坡长大约稳定在5.0 m;(2)不同坡度下,高寒土细沟水流输沙能力与流量表现为明显的线性正相关关系(Tc=Aq);小坡度的输沙能力受流量的影响程度大于大坡度;(3 ...

Multiscale Study of a Synergistic System in Carbon‐Coated Multimetal‐Based Selenides Toward Rapid and Highly Stable Sodium Storage

open access: yesRare Metals, Volume 45, Issue 3, March 2026.
ABSTRACT The development of sodium‐ion batteries (SIBs) is limited by slow charge transfer kinetics and large material volume changes caused by the large radius of Na+. Leveraging the excellent physicochemical properties and unique heterostructures of metal selenides, ultrafine hetero‐CuFeSe2‐CoSe2 nanoparticles are in situ wrapped by ...
