燃料电池是可持续能源技术的更清洁替代品之一,其质子交换膜仍然是燃料电池的重要组成部分,面临许多挑战和机遇。在这项研究中,制备了不同的吲唑和苯并三唑双膦酸并将其掺入新的Nafion掺杂的膜中,负载量达到5 wt%。对新膜进行表征,并使用电化学阻抗谱评估其质子电导率。在所研究的所有温度和相对湿度条件下,负载为1 wt%的膜均显示出比Nafion N-115更好的质子电导率。在这些条件下,质子电导率为98 mS cm的[羟基(1 H-吲唑-3-基)甲烷二基]双(膦酸)(BP2)掺杂的膜的最佳值被观察到-1。活化能( E a)值表明,格罗索斯(Grotthuss)和车辆机制都参与跨膜的质子传导。

Compositions and methods for inhibiting corrosion of metallic surfaces in contact with an aqueous medium such as copper, copper alloy, and steel surfaces of an open recirculating cooling water system. In certain embodiments, an aromatic triazole having an anionic substituent bonded to a nitrogen atom of the triazole (ANST) is used as the corrosion inhibitor. In other embodiments, the corrosion inhibitor is a reaction product of an aromatic triazole and an aldehyde (ATA).
our previous work on the development of CB2 ligands, reporting the design and synthesis of a series of benzimidazole-containing derivatives that were explored as selective CB2 ligands with binding affinity towards both CB1 and CB2 receptors. Seven out of eighteen compounds exhibited preferential binding ability to CB2 over CB1 receptors with potencies in the sub-micromolar or low micromolar range. In
在这里,我们继续我们之前开发 CB2 配体的工作,报告了一系列含苯并咪唑衍生物的设计和合成,这些衍生物被探索为对 CB1 和 CB2 受体具有结合亲和力的选择性 CB2 配体。18 种化合物中有 7 种表现出对 CB2 优于 CB1 受体的优先结合能力,其效力在亚微摩尔或低微摩尔范围内。特别是,我们确定了两种有前途的热门化合物,激动剂 1-[2-( N , N - 二乙基氨基)乙基]-2-(4-乙氧基苄基)-5-三氟甲基苯并咪唑 ( 3 ) (CB2: K i = 0.42 μM)和反向激动剂/拮抗剂1-丁基-2-(3,4-二氯苄基)-5-三氟甲基苯并咪唑( 11 ) (CB2:K i = 0.37 μM)。还对文献中报道的其他苯并咪唑进行的对接研究支持了在这一系列化合物中观察到的构效关系,并允许确定这些衍生物显示的激动剂和/或反向激动剂行为中涉及的关键接触。ADMET 特性的计算机评估表
