Shyamapada Nandi 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: 10981925
    Abstract: The invention discloses covalent organic nanosheets (CONs) made of triazole based diamine and triformyl phloroglucinol. The 2D structure of these nanosheets enables their facile amalgamation as an anodic material in a coin cell battery, which exhibits exceptionally high specific capacity of ˜720 mAh/g at a current density of 100 mA/g.
    Type: Grant
    Filed: December 2, 2019
    Date of Patent: April 20, 2021
    Inventors: Sattwick Halder, Kingshuk Roy, Shyamapada Nandi, Ramanathan Vaidhyanathan

  • Patent number: 10301727
    Abstract: The present invention discloses porous covalent organic frameworks (COF) supported noble metal-free nanoparticles which are useful as electrocatalysts for a water splitting system, and to the process for preparation of such electrocatalysts. The covalent organic frameworks (COF) supported noble metal-free nanoparticles have general formula (I): COF_AxBy(M)n??(Formula I) wherein COF is selected from a Tris (4-formylphenyl)amine terephthaldehyde polymer or a benzimidazole-phloroglucinol polymer; ‘A’ and ‘B’ each independently represent a transition metal selected from the group consisting of Ni, Co, Fe, Mn, Zn, and mixtures thereof; or ‘A’ and ‘B’ together represent a transition metal selected from the group consisting of Ni, Co, Fe, Mn, Zn, and mixtures thereof; ‘M’ represents hydroxide or a nitride ion; ‘x’ and ‘y’ represent the weight % of the metal loadings; or a ratio of x:y is between 0:1 and 1:0; and ‘n’ is an integer 1 or 2 or 3.
