Patent number: 8119392Abstract: This invention relates to biomaterials, biocompatible photoresists, and electroactive photoresists, and methods to engineer the interactions between biomaterials and cells. In one aspect, this invention provides for modifying surface topography through micro-patterning techniques that require no organic solvent development to reveal the lithographic patterns. Cells can be cultured on these surfaces directly and exhibit strong cell alignment features.Type: GrantFiled: April 30, 2004Date of Patent: February 21, 2012Assignee: The University of North Carolina at CharlotteInventors: Kenneth E. Gonsalves, Wei He

Patent number: 7008749Abstract: The present invention provides new high resolution resists applicable to next generation lithographies, methods of making these novel resists, and methods of using these new resists in lithographic processes to effect state-of-the-art lithographies. New nanocomposite resists comprising nanoparticles in a polymer matrix are provided in this invention. New chemically amplified resists that incorporate inorganic moieties as part of the polymer are presented herein, as are new chemically amplified resists that incorporate photoacid generating groups within the polymeric chain. Novel non-chemically amplified yet photosensitive resists, and new organic-inorganic hybrid resists are also provided herein. This invention and the embodiments described herein constitute fundamentally new architectures for high resolution resists.Type: GrantFiled: November 5, 2001Date of Patent: March 7, 2006Assignee: The University of North Carolina at CharlotteInventor: Kenneth E.

Patent number: 6033624Abstract: Methods for the manufacture of nanostructured metals, metal carbides, and metal alloys are presented, such metals including nanostructured aluminum, chromium, iron, molybdenum, vanadium, and steel. Preferably, the nanostructured steel is of the M50 type, and comprises iron, molybdenum, chromium, vanadium and carbon. Synthesis of M50 steel further comprising nanostructured aluminum, aluminum oxide, or aluminum nitride is also described. In accordance with an important feature of this invention, the grain size of the metals and metal alloys is in the nanometer range. In accordance with the method of the present invention, the nanostructured metals, metal carbides, and metal alloys are prepared via chemical synthesis from aluminum, iron, molybdenum, chromium and vanadium starting materials. Decomposition of metal precursors or co-precipitation or precipitation of metal precursors is followed by consolidation of the resulting nanostructured powders.Type: GrantFiled: September 25, 1996Date of Patent: March 7, 2000Assignee: The University of ConneticutInventors: Kenneth E.
