Rare Metals, Volume 45, Issue 10, October 2026.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.

Gongye shui chuli, 2019 以油酸咪唑啉中间体为原料，以2-溴乙基磺酸钠为季铵化试剂制备了咪唑啉磺酸盐。采用单因素分析和响应面法优化了咪唑啉磺酸盐季铵化反应条件，用扫描电镜和X能谱仪分析了N80表面形貌及腐蚀产物元素。结果表明，在响应面法确定的最优咪唑啉磺酸盐季铵化反应条件下，合成的咪唑啉磺酸盐实测的缓蚀率与预测结果非常接近，说明预测模型准确可靠；以咪唑啉磺酸盐为主剂的IM-S缓蚀剂能够有效地抑制CO2腐蚀介质对N80钢片的腐蚀。

使用粉尘图法测量交流电压下GIS绝缘表面电场电荷分布的影响因素研究
Dianci bileiqi, 2020 粉尘图法是一种常用的绝缘表面电场电荷分布的测量方法,但其在应用时仍然存在一些局限性,且目前对于影响其使用效果的因素的研究也存在不足。本论文在实际的GIS支柱绝缘子模型上对粉尘图法的各项可能的影响因素进行了研究,并针对离线情况下使用粉尘图法时存在的不足,提出了在带电情况下使用粉尘图法测量绝缘表面电场电荷分布的方法。研究结果表明,交流电压下粉尘图法的作用效果受到粉尘种类、外施电压大小、绝缘气体种类和压强等多种因素的影响,在使用时必须严格控制实验变量 ...

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.

Behavioral interventions to reduce demand for threatened freshwater turtles as pets
Conservation Biology, Volume 40, Issue 5, October 2026.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 ...

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 ...

Green Hydrogen in Brazilian Media: Dominant Narratives and Missing Dimensions of the Energy Trilemma
Politics &Policy, Volume 54, Issue 5, October 2026.ABSTRACT Media discourses help shape the visibility and legitimacy of energy transition pathways in the public sphere. This study examines how Brazilian mainstream newspapers framed green hydrogen and assesses the alignment of these narratives with the energy trilemma: energy security, environmental sustainability, and social accessibility. We analyzed
