Description

General description

Boric acid is a weak monobasic acid, it accepts OH^- ions, hence is a Lewis acid. In boric acid, B is sp² hybridized, forming a planar triangle structure.The principal oxide of boron, B₂O₃, is obtained as a vitreous solid by dehydration of boric acid at red heat.

Application

•Glass manufacturing: Used in the manufacture of glass fibers to enhance strength and color.
•Ceramics: employed in glazing ceramic wares for improved durability and aesthetics.
•Chemical Intermediate: Acts as a precursor for borates and other boron-based compounds.
•Nuclear Reactors: Utilized as a water coolant and neutron absorber in nuclear applications.
•Electrolytic Capacitors: Used in the production of electrolytic condensers and capacitors.

High Purity Carbon Adsorbents for Sample Preparation and Chromatographic Applications

Carbon Molecular sieves (CMS) are a versatile range of adsorbents that can be tailored for specific applications. Supelco® scientists have been synthesizing synthetic CMS carbons for several decades, starting from tailoring of the starting polymers/copolymers, to modifying the final properties of the subsequent CMS carbon.

High Purity Carbon Adsorbents for Chromatography

Synthetic CMS carbons offer tailored adsorbents for specific applications.

Mathematical modeling and experimental validation of the spatial distribution of boron in the root of Arabidopsis thaliana identify high boron accumulation in the tip and predict a distinct root tip uptake function.

Akie Shimotohno et al.

Plant & cell physiology, 56(4), 620-630 (2015-02-12)

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

N-glycosylation and topology of the human SLC26 family of anion transport membrane proteins.

Jing Li et al.

American journal of physiology. Cell physiology, 306(10), C943-C960 (2014-03-22)

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

Novel and simple headspace in-tube microextraction coupled with capillary electrophoresis.

Hye Ryeo Lee et al.

Journal of chromatography. A, 1346, 117-122 (2014-05-09)

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
