Background – Grass leaf has been suspected to cause immunoglobulin (Ig)E‐mediated immediate hypersensitivity reactions both in humans and in dogs. However, most studies in this area are case control studies without in vitro data showing the involvement of IgE in the reaction.

Electrolyte With Functionalized Boron Nitride Nanosheets for Dendrite‐Free Lithium Metal Anodes
ABSTRACT Lithium metal batteries (LMBs) are regarded as promising candidates for the next‐generation high‐energy‐density storage systems due to their unparalleled theoretical energy density and low redox potential. However, the commercialization of LMBs is tremendously plagued by the barbaric growth of lithium dendrite and the intricate decomposition ...

ABSTRACT Efficient and durable bifunctional electrocatalysts are vital for scalable water electrolysis. Here, we realize cobalt‐vacancy (Covac) engineering in CoFeP supported on N,P‐codoped carbon nanocages (Co1‐vacFeP/NPC) through a simple route comprising a CoFe Prussian blue analog precursor, phosphidation–pyrolysis, tannic‐acid etching, and a ...

ABSTRACT The development of efficient and stable bifunctional electrocatalysts is a key challenge for the industrialization of hydrogen production by water electrolysis. In this work, Co‐doped NiS/Ni3S2 heterostructured nanowire arrays (Co–NiS/Ni3S2 NA) were successfully constructed by precisely modulating the phase‐selective behavior of nickel ...

带电作业人员侵入110kV电缆终端塔间隙方式对套管及应力锥电场分布的影响研究
电缆终端套管是电缆线路的薄弱环节,为了掌握带电作业人员不同侵入电缆终端塔间隙的方式对套管及其应力锥电场分布的影响,根据实际110 kV电缆终端搭建仿真模型,因电缆终端塔和应力锥的尺度差异大采用子模型法来优化计算模型,分析了电缆终端正常运行及带电作业人员处于地电位作业、中间电位作业以及等电位作业3种情况对电缆终端应力锥电场分布的影响。计算结果表明:子模型法在保证计算精度的条件下可以有效减少网格数量和缩短计算时间;应力锥在3种作业方式下的电场变化相对于正常运行时均在3.5%以内 ...

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 ...
