Timothy J. Deming 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).

  • Modular, energy-dissipating material and method for using it
    Patent number: 6376636
    Abstract: Modular, energy-dissipating material prevents failure of adhesives, fibers and composite and other structures. The modules comprise folded subunits or domains that unfold in a stepped fashion at forces below that necessary to break the backbone of the material and, with adhesive material, below that necessary to break the bonds that fasten the material to surfaces being glued.
    Type: Grant
    Filed: October 28, 1999
    Date of Patent: April 23, 2002
    Assignee: The Regents of the University of California
    Inventors: Paul K. Hansma, Johannes Kindt, Timothy J. Deming, Daniel E. Morse, Galen D. Stucky
  • Methods and compositions for controlled polypeptide synthesis
    Publication number: 20020032309
    Abstract: Methods and compositions for the generation of polypeptides having varied material properties are disclosed herein. Methods include means for initiating the polymerization of aminoacid-N-carboxyanhydride (NCA) monomer by combining the monomer with an amido-containing metallacycle, for making self assembling amphiphilic block copolypeptides and related protocols for adding oligo(ethyleneglycol) functionalized aminoacid-N-carboxyanhydrides (NCAs) to polyaminoacid chains. Additional methods include means of adding an end group to the carboxy terminus of a polyaminoacid chain by reacting an alloc-protected amino acid amide with a transition metal-donor ligand complex to forming an amido-amidate metallacycle for use in further polymerization reactions. Novel compositions for use in peptide synthesis and design including five and six membered amido-containing metallacycles and block copolypeptides are also disclosed.
