  • Carbon nanotube hybrid material fabric, composite fabric, and personal protective apparel and equipment
    Patent number: 11542635
    Abstract: Carbon nanotube (CNT) fiber and sheets formed by a specialized gas assembly pyrolytic reactor method that permits gas phase integration of nano and micro particles (NMPs) are processed into yarn and fabric used in the manufacture of personal protective clothing and equipment that can be tailored via selection of NMPs for a wide variety of functionality depending on target application. The CNT-NMP hybrid fabrics may be designed to exhibit enhanced electrical and thermal conductivity, moisture wicking, air filtering, and environmental sensing properties.
    Type: Grant
    Filed: July 10, 2018
    Date of Patent: January 3, 2023
    Assignee: UNIVERSITY OF CINCINNATI
    Inventors: Mark J. Schulz, Sathya Kanakaraj, David Mast, Vesselin Shanov, Devika Chauhan, Guangfeng Hou, Vianessa Ng, Chenhao Xu, Rui Daniel Chen, Ashley Kubley, Xiaoda Hou, Richard Kleismit, Zhangzhang Yin

  • HEAT EXCHANGER TUBE
    Publication number: 20200240715
    Abstract: A flat tube for a heat exchanger is fabricated from a single sheet of metal material. The sheet of metal material has a first edge and a second edge, which are arranged adjacent to one another between a pair of broad walls of the tube. Flat sections extend from the edges and are disposed against one another. A pair of rounded walls arranged at an end of the tube connect the flat sections to the broad walls, and are joined by a weld bead within a space bounded by the outer surfaces of the rounded walls.

  • Methods to superheat carbon nanotubes
    Patent number: 9751765
    Abstract: A method for annealing multi-walled carbon nanotubes includes applying a high-frequency electromagnetic field to the carbon nanotubes and causing the carbon nanotubes to self-heat to a temperature and for a time effective to reduce defects and reduce a number of walls in some of the carbon nanotubes.
