Boric acidThermal analysisXRDFTIROptical polarized microscopyElectric susceptibilityWhen a special preparation procedure has been applied, the crystallization system of boric acid has been changed from triclinic to hexagonal: at temperatures between 60 and 70°C, under controlled pH conditions, the boric ...
The 11B nmr spectra of several compounds containing the group BOH have been measured in neutral, and alkaline solution. Salt formation shifts the 11B resonance far upfield (> 13 ppm) in the case of boric acid and simple arylboronic acids... MJS Dewar,R Jones - 《Journal of the American Ch...
BCN nanotube brushes have been obtained by the high temperature reaction of amorphous carbon nanotube (a-CNT) brushes with a mixture of boric acid and urea. The a-CNT brushes themselves were obtained by the pyrolysis of glucose in a polycarbonate membrane. The BCN nanotubes have been characterize...
Boric acid stimulates the plasma membrane H+‐ATPase of ungerminated lily pollen grains The stimulation of the plasma membrane (PM) H + ‐ATPase by boric acid was studied on a microsomal fraction (MF) obtained from ungerminated, boron‐depende... G Obermeyer,R Kriechbaumer,D Strasser,... ...
Synthesis and Structure Description of a New Tetradecaborate [H3N(CH2)2NH3]2[B14O20(OH)6] A new tetradecaborate, [H3N(CH2)2NH3]2[B14O20(OH)6](1), was synthesized by a boric acid 'flux' method, and characterized by X-ray powder diffraction, ICP, ... M Yang,Z Zhang,H Ding,...
F-) to form Lewis acid-base adducts [23]. In nature, boron-containing compounds may be generally divided into two categories, namely oxygen-linked boron taking the form of boric acids and organoboron molecules containing B-C covalent bonds [24], [25]. Positioned leftward near to carbon in...

As a crosslinking agent, boric acid (BA, H3BO3) was used. PVA can crosslink with BA without adding cation in using dimethyl sulfoxide (DMSO). The effects of BA addition and molecular weight (MW) on the formation of the physical structure in PVA/DMSO solutions were investigated. The ...
