Al-rich single-crystal mullite [Al(2)(Al(2.8)Si(1.2))O(9.6)] nanowires were prepared by B(2)O(3)-doped molten salts synthesis. The nanowires have diameters in the range 30-50 nm and typical lengths of 1 microm. The mullite nanowires were well dispersed and facile to obtain.

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

A new solid phase extractor, nano-scale diboron trioxide/titanium dioxide composite material, was synthesized and used for separation and/or preconcentration of trace cadmium ion from various samples. The characterization of the synthesized material was performed by scanning electron microscope (SEM), transmission
