Patents by Inventor Masoud Salavati-Niasari

Masoud Salavati-Niasari has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8993057
    Abstract: Silica-dysprosium oxide core-shell nanoparticles and a method for preparing the silica-dysprosium oxide core-shell nanoparticles are disclosed. Initially, ethyl silicate, n-butanol, ethylenediamine, and distilled water are mixed in the presence of ultrasonic radiation to prepare silica nanoparticles. Then, the silica nanoparticles are isolated. Next, the isolated silica nanoparticles, an acid, n-butanol, and dysprosium oxide are mixed in the presence of ultrasonic radiation to prepare silica-dysprosium oxide core-shell nanoparticles. Finally, the silica-dysprosium oxide core-shell nanoparticles are isolated.
    Type: Grant
    Filed: October 22, 2011
    Date of Patent: March 31, 2015
    Inventors: Masoud Salavati-Niasari, Fatemeh Davar, Morteza Enhessari, Mohammad Javad Esfahani
  • Patent number: 8361931
    Abstract: A method for preparing yttrium barium copper oxide (“YBCO”; “Y-123”; YBa2Cu3O7-x) superconducting nanoparticles is disclosed. The YBCO superconducting nanoparticles are prepared via a solid-state reaction by a solid-state reaction of an yttrium precursor, a barium precursor, and a copper precursor. One or more of the precursors are metal chelate compounds having acetylacetone ligands, which are highly stable and have a high compatibility with the other precursors.
