Ti02 nanopartides [10-12], NiO nanopartides [13] and various nanopartides of metal oxides [14] are formed in droplets or in a micellar environment. Cottam et al. reported a microfluidic synthesis of small nanorods of titanium oxide by fast mixing of an oleic add solution of tetraisopropoxytitanium (TTIP) with trimethylamine N-oxide dihydrate (TMAO) [15]. Both reaction solutions were mixed by a Y-shaped micro channel structure and conducted through a 40 cm microchannel with an internal channel width of 100 Jim. As a result, bunched assemblies of rod-like titanium dioxide were obtained. The length of the bundles was more than 100 nm and the diameter of the single rods was less than 10 nm.
