Gaoya dianqi, 2021 SF6的强温室效应对全球气候的潜在影响已经引起了人们的高度担忧,对SF6进行降解是处理SF6的一种有效手段。文中基于填充床式反应器（PBR）,针对系统中H2O浓度对降解SF6的影响进行了研究,并从降解效率与产物两个角度进行了分析。研究结果表明H2O能够在PBR中产生大量的OH与H自由基,这些活性自由基能够与SF6的初级分解产物进行次级反应从而促进其分解,提高了其降解率。实验发现,当SF6体积分数为2%时,最有利于促进SF6降解的水汽浓度为1%,其降解率达到95.69%。同时 ...

Rare Metals, Volume 45, Issue 3, March 2026.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 ...

Highly Anisotropic TbCo11Ti: Phase Evolution, Microstructure and Magnetic Properties
Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Among the 1:12‐type compounds, TbCo11Ti stands out due to its high Curie temperature and pronounced magnetocrystalline anisotropy. However, its magnetic behavior at room temperature and its phase evolution process have not been clearly established.

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Platinum (Pt)‐based catalysts are crucial for the commercialization of hydrogen/metal air batteries, but they suffer from Pt scarcity, high cost, and nanoparticle dissolution/agglomeration, mainly leading to performance degradation. We address this by synthesizing a PtFe alloy catalyst (PtFe–PA–NC) via a phytic acid (PA) assisted pyrolysis ...

Functional Ecology, Volume 40, Issue 3, Page 636-654, March 2026.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

Devouring the Invaders: The Racial‐Ecological Politics of the Chinese Crayfish Trade in Kenya
American Anthropologist, Volume 128, Issue 1, Page 183-194, March 2026.ABSTRACT This article examines entanglements of ecology, race, and foodways at Lake Naivasha in Kenya. Nonnative Louisiana red swamp crayfish (Procambarus clarkii), first introduced to Kenya in the 1960s, were once viewed as invasive but are now sought after as a delicacy among Kenya's Chinese community.
