, 2001 直接键合硅片界面的键合能依赖于界面成键的密度，是退火温度和时间的函数，界面反应激活能决定着成键的行为。硅片键合能随退火温度分两步增加,这种现象被归因于界面反应存在两种不同的激活能.将硅本征氧化层与硅热氧化层两种键合界面在退火过程中的行为进行了理论分析与比较.硅本征氧化层的键合能随温度的增加要比热氧化层界面的大 ...

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT High‐yield photocatalytic H2O2 production in sacrificial agent‐free pure water constitutes a critical bottleneck requiring urgent advances in energy catalysis. Although ZnIn2S4 (ZIS) exhibits favourable visible light absorption, it is plagued by severe bulk charge carrier recombination and scarce accessible surface‐active sites.

World Affairs, Volume 189, Issue 4, Winter 2026.ABSTRACT The move from unipolarity to a fluid and contested multipolar world order has significantly changed the way African nations form national security policy due to changes in the nature of the strategic environment of those states. Much of the literature has focused on how the actions of major world powers ‐ the United States, China and Russia ...

, 2017 表面电势是微纳流控芯片中流体流动的重要参数。本文介绍了基于AFM胶体探针技术测量液固界面DLVO力并进一步测量表面电势及表面电荷密度的方法。本文改进了胶体探针制作的技术手段，并提出用双探针法测量胶体探针的弹性系数。在0.1-1mM浓度范围内的NaCl溶液中，测量了硅、二氧化硅和氮化硅液固界面双电层内的DLVO力及表面电势。实验结果表明胶体探针技术可以很好地测量液固界面的DLVO力，尤其对静电力指数变化段非常敏感。通过DLVO力曲线可以间接测量表面电势、表面电荷密度等重要参数 ...

Risks of concealing environmental degradation
Conservation Biology, Volume 40, Issue 5, October 2026.Abstract Current practice seeks to conceal the visual impact of land‐use change (i.e., development). Six percent of development impact assessments in Australia and 14% of the World Bank's assessments recommend visual impact mitigation. This mitigation results in, for example, vegetated buffer strips alongside cleared agricultural areas and earthen ...

Assessing and strengthening community‐based coastal governance
Conservation Biology, Volume 40, Issue 5, October 2026.Abstract Community‐based coastal governance is essential for biodiversity conservation and sustainable livelihoods, yet many communities continue to face significant challenges in establishing and sustaining effective governance systems. We sought to improve understanding of the current status of community‐based coastal governance across five countries

Predictive evolutionary genomics: principles, validation, and practice
New Phytologist, Volume 252, Issue 1, Page 36-48, October 2026.Summary Climate change and habitat loss are driving rapid evolutionary responses in populations world‐wide, which creates an urgent need for evolutionary forecasting in conservation and agriculture. Such forecasting can be categorized into three time scales: trait‐based models that use multivariate quantitative genetic equations to project correlated ...
