一般說明

硼酸是一种弱单碱路易斯酸（电子对受体），广泛用于玻璃制造、阻燃剂、润滑剂、缓冲剂和中子吸收剂。

應用

硼酸可作为催化剂来合成：
  • 通过肉桂酸与苯胺的酰胺化反应制备 N-取代肉桂酰胺。
  • 以甘油为助催化剂，通过环氧化物与芳香胺的区域选择性开环制备 β-氨基醇。
  • 通过硫醇到α, β-不饱和化合物的硫杂 Michael 加成制备有机硫化合物。
它也可用作活化剂，在硼氢化钠环境下通过醛和酮醇的无溶剂还原制备醇类。

Building plasmonic nanostructures using biomolecules as scaffolds has shown great potential for attaining tunable light absorption and emission via precise spatial organization of optical species and antennae. Here we report bottom-up assembly of hierarchical plasmonic nanostructures using DNA origami templates

The human solute carrier (SLC26) family of anion transporters consists of 10 members (SLCA1-11, SLCA10 being a pseudogene) that encode membrane proteins containing ~12 transmembrane (TM) segments with putative N-glycosylation sites (-NXS/T-) in extracellular loops and a COOH-terminal cytosolic STAS
