Sudarshan SINGHA 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.
