Patents by Inventor Jing C. Zhou

Jing C. Zhou 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).

  • Photoresponsive nanoparticles as light-driven nanoscale actuators
    Patent number: 8652352
    Abstract: Photoresponsive shape memory nanoparticles have a layered smectic ordering and include a photoresponsive moiety selected from the group consisting of azobenzene, stilbene, and spiropyran. Multiple cycles of contraction and extension in these materials can be controlled by UV and visible light. By changing light intensity and exposure time, the magnitude of actuation can be modulated.
    Type: Grant
    Filed: August 22, 2013
    Date of Patent: February 18, 2014
    Assignee: The United States of America, as represented by the Secretary of the Navy
    Inventors: Jawad Naciri, Jing C. Zhou, Banahalli R. Ratna
