General description
Anhydride can be obtained by heating boric acid at temperatures higher than 160oC.1
Application
Reducing boron anhydride in the presence of sodium yields amorphous boron. Whereas reducing in the presence of aluminum at high temperatures affords crystalline boron. 1

Glassy carbon electrode modified with boron oxide nanoparticles supported on multiwall carbon nanotubes was obtained via a facile approach. The as-prepared modified electrode exhibits excellent electrocatalytic activity toward the redox of glucose in pH 7.0 phosphate buffer solution. The electrochemical

A facile strategy based on the reaction of urea and boric acid is developed for the synthesis of toxicity-free BCNO nanocrystals containing carbon impurities and which exhibit efficient multi-color fluorescence under both single-photon and two-photon excitation.
