Rare Metals, EarlyView.ABSTRACT Regulating negative parameters of metacomposites is mainly limited by their unclear mechanisms, which affects their practical applications in new sensing, communication, electromagnetic (EM) protection and other fields. This work proposes a dual‐functional competitive design strategy based on the waste corncob‐derived carbon/polyaniline ...

Rare Metals, EarlyView.ABSTRACT Single‐atom catalysis hinges on fundamental challenges in precisely controlling metal‐support interactions and rationally regulating metal–adsorbate relationships. Herein, we report a universal strategy for constructing highly efficient and well‐defined Cu(I) single‐atom catalysts based on a trifurcate AlL3 molecular support.

Coastal reclamation impacts on carbon storage in China’s coastal wetland [PDF]
, 2017 滨海湿地具有较高的初级生产力和较缓慢的有机质降解速率，是缓解全球变暖的有效碳汇，得到全球学术界的广泛关注。近年来由于人口增长和沿海城市的快速发展，海岸带地区围填海活动呈加剧趋势，导致滨海湿地的急剧退化。开展围填海活动对滨海湿地碳储量造成影响的研究，对我国海岸带围填海活动的优化管理、制定滨海湿地保护行动计划以及减缓气候变化的战略决策具有非常重要的学术价值和现实意义。 本论文以全国围填海区内的滨海湿地作为研究对象，基于全国围填海土地利用分类数据、滨海湿地和沿海自然保护区空间分布数据以及文献检索碳密度数据 ...

Rare Metals, EarlyView.ABSTRACT Skin wound injuries are often accompanied by bacterial infections and severe inflammation. Especially, M1‐type macrophages at the wound site can trigger a cascade of inflammatory responses, mediating a vicious cycle of inflammation. Meanwhile, hypoxia further exacerbates vascular damage and constriction in the wound microenvironment, thereby ...

Distribution of sulfur in plants and sediments of mangrove in China and Influential Factors [PDF]
, 2008 以全国红树林主要分布地区——海南、广东、广西、福建共4个省份13个地区为研究对象，采集红树植物、沉积物样品。通过测定红树植物叶片，茎，根中的硫含量，分析红树植物中硫的累积和分布规律。通过测定表层沉积物，柱状沉积物中硫含量和pH值，盐分，有机质，土壤粒度等环境因子，分析红树林湿地沉积物植物中硫的分布规律，讨论环境影响因子对红树林湿地中硫的影响。通过研究，得出如下几点主要结论：主要结果如下：（1）我国红树林湿地表层沉积物中硫的平均含量达到0.214%，高于附近非红树林区沉积物中硫的平均含量（0.153 ...

Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Organic phosphorus mineralization is a critical process in the phosphorus cycle, governing phosphorus bioavailability for plants. The PhoD gene, which encodes the key enzyme alkaline phosphatase, serves as a valuable biomarker for this process.

Threats to and management of Natura 2000 protected areas relative to agricultural practices
Conservation Biology, EarlyView.Abstract The Natura 2000 (N2K) network combines biodiversity protection and socioeconomic targets. Human activities, such as agricultural practices, can affect biodiversity in N2K sites in diverse ways. Limiting activities with negative impacts while enforcing land management that supports biodiversity is crucial for effective conservation.

Lessons from an eradication under multiple constraints of an island rat population of record density
Conservation Biology, EarlyView.Abstract Invasive rats threaten island biodiversity, disrupting ecosystems and endangering native species. Although rat eradication has succeeded on many islands, tropical islands present unique management challenges. Strict regulations and financial constraints on some tropical islands further limit proven eradication methods, complicating rodent ...
