一般說明

硼酸是一种弱的一元酸，它可接受OH- 离子，因此是一种路易斯酸。在硼酸中，B是sp2 杂化的，并形成平面三角形结构。硼的主要氧化物，B2O3可通过在红热下使硼酸脱水获得玻璃状固体。

應用

硼酸用途广泛，可用作玻璃工业中的阻燃剂，也用于缓冲液配制。
硼酸适用多个领域，例如


  • 用在玻璃纤维中，增强其耐受性和颜色
  • 用于上釉陶瓷器皿
  • 作为缩合剂、化学中间体，和作为制备硼酸盐和其他硼基化合物的前体
  • 作为核反应堆中的水冷却剂
  • 用于电解电容器和电容器1

Boron, an essential micronutrient, is transported in roots of Arabidopsis thaliana mainly by two different types of transporters, BORs and NIPs (nodulin26-like intrinsic proteins). Both are plasma membrane localized, but have distinct transport properties and patterns of cell type-specific accumulation

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

In liquid phase microextraction, high enrichment factors can be obtained using an acceptor phase of small volume. By hanging an acceptor drop at the separation capillary tip, single drop microextraction (SDME) can be in-line coupled with capillary electrophoresis (CE). The

The three oncogenes, ErbB receptors, Ras proteins and nucleolin may contribute to malignant transformation. Previously, we demonstrated that nucleolin could bind both Ras protein and ErbB receptors. We also showed that the crosstalk between the three proteins facilitates anchorage independent
