Advances in Elemene Nanodelivery Systems: From Material Design to Disease Treatment
Rare Metals, EarlyView.ABSTRACT Elemene (ELE) is a bioactive sesquiterpenoid extracted from traditional Chinese herbs, demonstrating broad‐spectrum antitumor, anti‐inflammatory, and analgesic properties with significant therapeutic potential. However, its clinical utility is constrained by inherent physicochemical limitations, including volatility and hydrophobicity, which ...

Rare Metals, EarlyView.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 ...

Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract The nested subset pattern (nestedness) has been widely used to explain species distributions in island and fragmented systems. Mountain sky islands serve as critical natural laboratories for understanding the evolutionary consequences of geographic isolation and climate

Policy 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.

切向电场主导下C4F7N/CO2混合气体中环氧复合材料表面电荷积聚特性及机理研究
Gaoya dianqi, 2023 气固界面的电荷积聚问题是诱发沿面闪络的重要原因，而当前C4F7N/CO2混合气体中电荷积聚特性的相关研究还不够充分。为研究C4F7N/CO2混合气体中表面电荷积聚特性及机理，本文通过指型电极构建极不均匀电场，测量了环氧复合材料在C4F7N/CO2混合气体中的表面电荷分布特性；进一步的，为理清表面电荷来源及迁移特性，测量了冲击电压下C4F7N/CO2混合气体中材料表面电位，比较了附加背板电极前后的表面电荷分布。研究表明，C4F7N/CO2混合气体与SF6中表面电位分布形态相似 ...

Shuitu Baochi Xuebao, 2020 为探究紫色土坡地植物篱篱前淤积带与篱下土坎土壤抗蚀性的差异及变化规律，选取遂宁市水土保持试验站10°新银合欢植物篱小区（T1）、10°和15°香根草植物篱小区（T2和T3）进行研究。研究小区布设有上、中、下坡篱带，分别采集篱前淤积带和篱下土坎（下坡无）的表土样，测定有机质含量、水稳性团聚体和微团聚体组成，运用主成分分析法对土壤抗蚀性进行分析。结果表明：同一篱带，土壤有机质含量、团聚度和团聚状况均是篱前淤积带高于篱下土坎，土壤水稳性团聚体含量和抗蚀性综合指数则反之，篱下土坎的抗蚀性综合指数是篱前淤积带的1.
