ABSTRACT Magnetic particles coated with carbon shells have been considered as promising electromagnetic wave absorption materials with antibacterial features. However, how to precisely control the monodispersed magnetic nanoparticles on a carbon matrix to manipulate impedance matching and antibacterial performances is still a key challenge.

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.

MBi2O4(M=Mg、Ca、Sr、Ba)的制备及其可见光催化活性
光催化在环境治理和太阳能储能方面都具有潜在的应用前景,受紫外线激发的TiO2光催化剂在催化降解有机物、自洁、杀菌抗菌等方面都有较多应用研究报道。太阳光能中,紫外光线约占4%,可见光约占了43%。常用锐钛矿型TiO2的带隙能为3.2ev,在利用太阳能方面受到了一定限制。开发新型可见光响应的半导体光催化剂,在利用太阳能治理环境方面也有着广泛的应用前景。本文报道了一种新型可见光光催化剂MBi2O4(M=Mg、Ca、Sr、Ba)的制备方法;并初步探讨了原子半径对系列光催化剂MBi2O4催化活性的影响机理 ...

Risks of concealing environmental degradation
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 ...

Scientists’ warning on the global destruction of rock outcrop ecosystems
Abstract Rock outcrops are geological formations that harbor a highly specialized biota adapted to harsh environmental conditions that differ from their surrounding landscapes. They are globally distributed, especially in old, highly weathered landscapes, and can function as habitat islands containing high levels of endemism and distinct evolutionary ...

葡萄糖-6-磷酸脱氢酶缺乏致新生儿黄疸溶血机理探讨——Ⅰ.抗氧化红细胞酶活性分析
对红细胞谷胱甘肽过氧化酶(GSH-Px),谷胱甘肽还原酶(GR)、超氧化物歧化酶(SOD)及谷胱甘肽(GSH)含量进行了测定,结果显示:①新生儿GSH-Px活性显著低于成人,这可能与新生儿抗氧化能力低下有一定关系;②G6PD缺乏的成人GR活性显著高于正常成人,提示GR活性增高在一定程度上能代偿G6PD活性和GSH含量下降造成的影响;③G6PD缺乏的成人及新生儿GSH含量均显著低于相应正常对照,但GSH含量降低可能不是导致新生儿溶血的重要环节。

Behavioral interventions to reduce demand for threatened freshwater turtles as pets
Abstract Growing demand for freshwater turtles as pets has fueled illegal trade and accelerated wild population declines, underscoring the need for theory‐based demand‐reduction interventions. We conducted a three‐part randomized controlled trial with active turtle keepers (n = 1800) in China to test conservation‐ and legality‐framed messages by ...
