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

Mg2B2O5 nanowires with (010) twins were synthesized for the first time using a catalyst-free method. The microstructure of the Mg2B2O5 nanowires has been extensively studied by cross-sectional high-resolution transmission electron microscopy. Nanoindentation tests were performed directly on individual nanowires to

CaO-SiO(2)-P(2)O(5)-B(2)O(3) glass ceramics directly bond to bone and have potential use as a bone substitute material. The present study evaluated the toxicity from subchronic intravenous administration of CaO-SiO(2)-P(2)O(5)-B(2)O(3) glass ceramics to male and female Sprague-Dawley rats. The rats were divided
