Journal ArticleDOI
Stable boron isotope fractionation between dissolved B(OH)3 and B(OH)4
TL;DR: In this paper, the authors examined the calculations underlying this value and concluded that α(B 3 − B 4 ) = 1.0193 at 300 K is sensitive to experimentally determined vibrational frequencies and the theoretical methods used to calculate the molecular forces.
Journal ArticleDOI
A study of the formation and self-lubrication mechanisms of boric acid films on boric oxide coatings
TL;DR: In this paper, the formation and self-lubrication mechanisms of boric acid films on boric oxide coatings prepared by vacuum evaporation were investigated, and a triclinic crystal structure was proposed for the mechanism of self lubrication.

Spontaneous hydrolysis of sodium borohydride in harsh conditions
Jérôme Andrieux,Umit B. Demirci,Julien Hannauer,Christel Gervais,Christelle Goutaudier,Philippe Miele +5 more
TL;DR: In this article, the spontaneous hydrolysis of sodium borohydride NaBH4, which is a potential hydrogen storage material for small, portable applications, was carried out at temperatures of 30-80°C.

The study of Bi3B5O12: synthesis, crystal structure and thermal expansion of oxoborate Bi3B5O12
Stanislav K. Filatov,Yurij Shepelev,Rimma S. Bubnova,Natalia Sennova,A. V. Egorysheva,Yury F. Kargin +5 more
TL;DR: In this paper, a new data on the crystal structure, thermal expansion and IR spectra of Bi 3 B 5 O 12 was presented, which was obtained from the melt of the same stoichiometry by Czochralski technique.
Journal ArticleDOI
Boron speciation in aqueous fluids at 22 to 600°C and 0.1 MPa to 2 GPa
TL;DR: In this article, the frequency shifts of the 877 cm−1 Raman line of [B(OH)3]0 in aqueous fluid with temperature between 22 and 600°C and pressure from 0.1 MPa to ∼2 GPa were determined.

The vibrational spectra of orthoboric acid and its thermal decomposition products
P. Broadhead,G.A. Newman +1 more
TL;DR: In this paper, the vibrational spectrum of orthoboric acid was found to be essentially in agreement with the results of earlier workers, and it was assigned to OH groups with very strong intermolecular hydrogen bonds.
Journal ArticleDOI
The low-frequency vibrations of molecular crystals. IV. boric acid
TL;DR: In this paper, the O-H torsional frequency was observed near 800 cm−1, and the twofold barrier to internal rotation around the H-O-B bond was calculated to be 23 kcal mole.
