Patents by Inventor Davin Glenn Piercey

Davin Glenn Piercey 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: 11858902
    Abstract: The present disclosure relates to a novel compound suitable for a metal-free primary explosive, and the method of making and using the novel compound. The novel compound can undergo a deflagration to detonation transition (DDT) to initiate detonation of a larger body of secondary explosive.
    Type: Grant
    Filed: April 5, 2021
    Date of Patent: January 2, 2024
    Assignee: Purdue Research Foundation
    Inventors: Davin Glenn Piercey, Dominique Wozniak
  • Patent number: 11530203
    Abstract: The present disclosure relates to a novel tetrazole azasydnone, a method of making the novel tetrazole azasydnone, and a method of using the novel tetrazole azasydnone as a primary explosive. In one aspect, the novel tetrazole azasydnone has a structure of formula I: wherein A? represents a cation with a 1+ charge.

  • Patent number: 11434211
    Abstract: This disclosure shows the ability of a readily-available oxidizer to achieve oxidation of 5-amino-1H-tetrazole (5-AT) to 5-nitrotetrazole (5-NT) in high yields in a single pot synthesis. This strategy reduces the synthesis of this important energetic material down to a single step and eliminates highly sensitive diazonium and copper salt primary explosive intermediates. The overall yield of this process is 48-53% and the resultant aqueous solution of product effectively used for the preparation of nitrotetrazole-containing primary explosive DBX-1. Unlike current methods of nitrotetrazole preparation, the novel method is entirely solution-based and prepares a final solution of sodium nitrotetrazolate, never once needing to handle energetic intermediates or products, making it a much safer method of nitrotetrazole preparation.

  • Patent number: 8410243
    Abstract: Novel aromatic ether-containing monomers are described along with processes for their preparation and their polymerization into corresponding aromatic ether-containing polyfluorenes. These polyfluorenes exhibited stable blue-emission and therefore have application in polymer light-emitting devices.
