Title
(EN) A SOL-GEL PROCESS FOR SYNTHESIS OF NANOCRYSTALLINE OXIDES
(FR) PROCÉDÉ SOL-GEL POUR LA SYNTHÈSE D'OXYDES NANOCRISTALLINS
Abstract
(EN) A Continuous flow synthesis of nanocrystalline metal oxides by rapid sol-gel process is disclosed. The process disclosed uses an impinging microjet micromixer device to obtain the nano crystalline metal oxides. A method of fabricating and assembling the impinging microjet micromixer is also disclosed herewith.
