Michael P. Zach 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).

  • Ultrafast and ultrasensitive hydrogen sensors based on self-assembly monolayer promoted 2-dimensional palladium nanoclusters
    Patent number: 7389671
    Abstract: A device and method of making same. The device or hydrogen detector has a non-conducting substrate with a metal film capable of absorbing hydrogen to form a stable metal hydride. The metal film is on the threshold of percolation and is connected to mechanism for sensing a change in electrical resistance in response to the presence of hydrogen in contact with the metal film which causes an increase in conductivity.
    Type: Grant
    Filed: November 7, 2006
    Date of Patent: June 24, 2008
    Assignee: UChicago Argonne, LLC
    Inventors: Tao Xu, Michael P. Zach, Zhili Xiao
