Patents by Inventor Divesh Narayan Srivastava

Divesh Narayan Srivastava 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).

  • Publication number: 20170082576
    Abstract: The present invention provides a polymer based bulk conducting electrodes. These electrodes have several advantages over the conventional screen printed and coated electrodes. The present invention also provides biodegradable variant of these electrodes. Such electrode are found comparable to the conventional noble metal electrode and glassy carbon electrode in various electrochemical techniques like cyclic voltammetry of different redox couple, amperometric sensing of hydrogen peroxide, stripping voltammetry of lead (II) ion, electrodeposition of zinc and electropolymerization of aniline in aqueous medium.

  • Publication number: 20160231269
    Abstract: The present invention relates to gold wires and electrodes fashioned from natural fibres. In particular, fine natural fibres such as coir fibre, jute fibre, sisal fibre, banana fibre, and human hair, which are mechanically strong and flexible, were used as templates over which an 80-200 nm layer of gold was coated by sputter coating. The composite materials were shown to have low electrical resistivity and functioned normally as electrodes in conventional electrochemical applications such as cyclic voltammetry and anodic stripping voltammetry. Although the present invention focused on the use of single fibres and gold coating exclusively, bundles of naturally aligned fibres and coatings of metals other than gold are logical extensions of the invention.

  • Patent number: 9259663
    Abstract: The present invention relates to natural crude salt formulations arid their cost-effective preparation. In particular, the invention discloses the fractionation of seawater into three fractions which can thereafter be suitably combined to reconstitute seawater in its pristine form for its various applications such as growth of marine microbes, flora and fauna in a marine environment, especially where such environments have to be created in locations far removed from the sea and/or where there is a requirement to modify the composition of seawater to better its performance. The fractions can also be blended appropriately to exclude the major constituent, namely sodium chloride, and thereby be useful for mineralization/re-mineralization of waters which are deficient in mineral nutrients such as calcium, magnesium, potassium, sulphate and bicarbonate including rain water and desalinated waters obtained through thermal/RO desalination.
