Patent number: 9537157Abstract: A nanoconverter or nanosensor is disclosed capable of directly generating electricity through physisorption interactions with molecules that are dipole containing organic species in a molecule interaction zone. High surface-to-volume ratio semiconductor nanowires or nanotubes (such as ZnO, silicon, carbon, etc.) are grown either aligned or randomly-aligned on a substrate. Epoxy or other nonconductive polymers are used to seal portions of the nanowires or nanotubes to create molecule noninteraction zones. By correlating certain molecule species to voltages generated, a nanosensor may quickly identify which species is detected. Nanoconverters in a series parallel arrangement may be constructed in planar, stacked, or rolled arrays to supply power to nano- and micro-devices without use of external batteries. In some cases breath, from human or other life forms, contain sufficient molecules to power a nanoconverter.Type: GrantFiled: April 24, 2015Date of Patent: January 3, 2017Assignee: Lawrence Livermore National Security, LLCInventors: Yinmin Wang, Xianying Wang, Alex V.

Patent number: 8344597Abstract: A nanoconverter is capable of directly generating electricity through a nanostructure embedded in a polymer layer experiencing differential thermal expansion in a stress transfer zone. High surface-to-volume ratio semiconductor nanowires or nanotubes (such as ZnO, silicon, carbon, etc.) are grown either aligned or substantially vertically aligned on a substrate. The resulting nanoforest is then embedded with the polymer layer, which transfers stress to the nanostructures in the stress transfer zone, thereby creating a nanostructure voltage output due to the piezoelectric effect acting on the nanostructure. Electrodes attached at both ends of the nanostructures generate output power at densities of ˜20 nW/cm2 with heating temperatures of ˜65° C. Nanoconverters arrayed in a series parallel arrangement may be constructed in planar, stacked, or rolled arrays to supply power to nano- and micro-devices without use of external batteries.Type: GrantFiled: December 16, 2010Date of Patent: January 1, 2013Assignee: Lawrence Livermore National Security, LLCInventors: Donald J.

Publication number: 20040060620Abstract: In accordance with the invention, nanostructured metallic materials having high tensile strength and increased ductility are prepared by providing a metallic material, deforming the metallic material to form a plurality of dislocation cell structures, annealing the material at a temperature from about 0.3 to about 0.7 of its absolute melting temperature, and cooling the annealed metallic material. The result is a nanostructured metal or alloy having increased tensile strength as compared with the corresponding coarse-grained material and substantially greater ductility as compared with nanostructured material made by conventional processes. Using this process applicants have made nanostructured alloys with tensile strengths in excess of 1.5 Gpa and ductility greater than 1 per cent strain-to-failure. They have also made nanostructured metals with tensile strength in excess of 400 MPa and ductility in excess of 50% strain-to-failure.Type: ApplicationFiled: April 29, 2003Publication date: April 1, 2004Applicant: JOHNS HOPKINS UNIVERSITYInventors: Ev An Ma, Yinmin Wang, Mingwei Chen
