Nanocomposites with magnetic iron oxide as the hollow core, silica as the middle shell and calcium silicate as the outer shell are the ideal agent for application in medical diagnosis and therapy. In this paper, by sol–gel coating the self-assembled nanoparticles of magnetic iron oxide with silica, then reacting with Ca(NO 3 ) 2 ·4H 2 O at 600°C in inert N 2 atmosphere,...
Silica/cadmium hydroxide (SiO 2 /Cd(OH) 2 ) composite nanotubes have been successfully synthesized by a microwave-assisted solvothermal method at 100°C using water-dissolvable KCdCl 3 nanowires as the precursor and template. The KCdCl 3 nanowires are prepared by adding an aqueous solution containing CdCl 2 and KI into anhydrous ethanol at room temperature. The...
