Patents by Inventor Kulamani Parida

Kulamani Parida 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).

  • Modified layered double hydroxide (LDH) and a process for preparation thereof for C—C bond forming reactions
    Patent number: 9035086
    Abstract: The present invention relates to a covalently organo-modified LDH (LDH/APTES) was found to be an efficient and reusable heterogeneous catalyst for C—C bond forming reactions (i.e. Aldol condensation, Knoevenagel condensation, Henry reaction, Michael addition). More particularly, this catalyst shows consistent activity for several cycles in C—C bond forming reaction. These catalysts were successfully characterized by XRD, FT-IR, 29Si CP MAS NMR.
    Type: Grant
    Filed: February 14, 2012
    Date of Patent: May 19, 2015
    Assignee: COUNCIL OF SCIENTIFIC & INDUSTRIAL RESEARCH
    Inventors: Kulamani Parida, Sudarshan Singha, Mitarani Sahoo
  • Ruthenium complex intercalated N-doped or N,S-codoped titania pillared montmorillonite and a process for the preparation thereof
    Patent number: 9023750
    Abstract: This present invention relates to a Ruthenium complex intercalated N-doped or N,S-codoped titania pillared montmorillonite, a multifunctional photocatalyst and a process for the preparation thereof. More particularly, the present invention provides a green photochemical route towards a variety of light driven redox reactions such as organic dye degradations, photocatalytic water splitting and various organic transformation reactions oriented to the synthesis of fine chemicals.
