Digital Rights Activism in Multilevel Governance
European Policy Analysis, EarlyView.ABSTRACT Multilevel governance (MLG) without a clear hierarchical structure can create power imbalances among various actors, particularly in settings with overlapping jurisdictions and policy areas. This dynamic is especially pronounced in Internet governance, which faces a complex interplay of domestic laws, state interdependence, and heightened ...

Nitrogen Anchoring Effect Triggering Improved Reversible Hydrogen Storage of Mg(BH4)2
Rare Metals, EarlyView.ABSTRACT This research uncovered the influence of nitrogen‐doped MXene Ti3CN on the reversible hydrogen storage properties of Mg(BH4)2. The Mg(BH4)2‐20Ti3CN composite began releasing hydrogen at a temperature of 80°C. In addition, the composite discharged over 8.8 wt% hydrogen at a comparatively lower temperature of 270°C, whereas the pure Mg(BH4)2 ...

Filling Uniformity of AgNPs in EMI Shielding Patch Regulated by Surface Morphology
Rare Metals, EarlyView.ABSTRACT Silver nanoparticles (AgNPs) are extensively employed for electromagnetic interference (EMI) shielding owing to their remarkable conductivity, and are commonly incorporated into polymer matrices. Therefore, the uniformity of the AgNP distribution within the polymer matrix is a crucial factor that affects the EMI shielding performance.

A Study on the Active Life Expectancy and the Influencing Factors of the Elderly in China [PDF]
, 2016 随着人口老龄化社会的发展，老年人的生活质量备受关注。一些现象表明：健康一定可以长寿，但长寿不一定健康。在我国，老龄化进程不断加快，为使我们的老龄化社会更加和谐，我们有必要关心老年人的生活质量，关注老年人处于健康的寿命长度。 本文选用中国老年健康影响因素跟踪调查项目（CLHLS）的2008~2011年纵向数据，并运用多状态生命表法，分别从不同年龄、不同性别、不同城乡居住地、不同受教育程度、不同婚姻状况、不同烟酒状况、不同身体锻炼情况、不同患病状态等方面来计算健康预期寿命，并分析不同因素对健康预期寿命的影响。

Rare Metals, EarlyView.ABSTRACT Converting CO2 to CH4 under mild conditions is a promising strategy for solving environmental and energy problems, but also a challenge. In this work, the low‐temperature CO2 hydrogenation process over Ni/CeO2 catalysts was significantly accelerated by optimizing the H2 dissociation ability of Ni through the size effect, thus A‐Ni/CeO2 with an
