  • Process for metal oxide and metal nanoparticles synthesis
    Patent number: 8382877
    Abstract: The present invention provides an approach to control the generation and grow of nanocrystal with membrane diffusion method and related apparatuses to produce inorganic oxide nanopowders and metal nanoparticles. With this method, the size and size distribution of inorganic oxide nanopowders and metal nanoparticles can be tuned. It overcomes the shortcomings possessed by the common chemical and physical method of preparing nanoparticles.
    Type: Grant
