Gillian Althea Maria Reynolds 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).

  • Process for improving the oxidation resistance of carbon nanotubes
    Patent number: 8414757
    Abstract: The disclosure relates to processes for the electrochemical modification of electron emitting materials such as carbon nanotubes. The processes improve the oxidation resistance of the electron emitting materials when they are fired in an oxygen-containing atmosphere such as air. The disclosure also relates to the preparation of cathodes or cathode assemblies, for use in a field emission device, wherein are contained an electron field emitter made from such electron emitting material.
    Type: Grant
    Filed: February 26, 2010
    Date of Patent: April 9, 2013
    Assignee: E I du Pont de Nemours and Company
    Inventors: Steven Dale Ittel, Gillian Althea Maria Reynolds, Ming Zheng
  • METHOD FOR THE ELECTROCHEMICAL DEPOSITION OF CARBON NANOTUBES
    Publication number: 20100326834
    Abstract: This invention relates to the electrochemical deposition of carbon nanotubes (“CNTs”) on a substrate using an electrochemical cell. A dispersion of a complex of CNTs and an anionic polymer is neutralized and thereby caused to deposit on the anode plate of the cell.
    Type: Application

  • Processes for growing carbon nanotubes in the absence of catalysts
    Publication number: 20100119435
    Abstract: Processes for increasing the production rate of single-wall carbon nanotubes using a disordered carbon target are disclosed. The processes use a disordered carbon target and include vaporization of the target in the presence of a non-oxidizing gas. The single-wall nanotubes produced can be incorporated into electronic devices such as diodes and transistors.
