General description

Boric acid is a weak monobasic Lewis acid(electron pair acceptor), which finds application in the areas of glass making, fire retardant, lubrication agent, buffer, and neutron absorber.

Application

Boric acid can be used as a catalyst to synthesize:

N-substituted cinnamamides via amidation reaction between cinnamic acid and benzylamines.
β-Aminoalcohols through the regioselective epoxides ring opening with aromatic amines in the presence of glycerol as a co-catalyst.
Organosulfur compounds via thia-Michael addition of thiols to α, β-unsaturated compounds.

It can also be used as an activator for the solvent-free reduction of aldehydes and ketones to alcohols in the presence of sodium borohydride.

Hierarchical assembly of plasmonic nanostructures using virus capsid scaffolds on DNA origami templates.

Debin Wang et al.

ACS nano, 8(8), 7896-7904 (2014-07-16)

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

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

Interfering with the interaction between ErbB1, nucleolin and Ras as a potential treatment for glioblastoma.

Yona Goldshmit et al.

Oncotarget, 5(18), 8602-8613 (2014-09-28)

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

Green electrochemical template synthesis of CoPt nanoparticles with tunable size, composition, and magnetism from microemulsions using an ionic liquid (bmimPF6).

Albert Serrà et al.

ACS nano, 8(5), 4630-4639 (2014-05-03)

Electrodeposition from microemulsions using ionic liquids is revealed as a green method for synthesizing magnetic alloyed nanoparticles, avoiding the use of aggressive reducing agents. Microemulsions containing droplets of aqueous solution (electrolytic solution containing Pt(IV) and Co(II) ions) in an ionic
