The trenches are then filled with a filler material. Any filler and/or nanostructures material extending beyond the trench is removed. The silicon substrate is etched away, resulting in a nanopellet surrounding the nanostructures and wherein each nanostructures has a generally uniform length and direction. Nanostructures can comprise nanotubes, nanowires and nanofibers. The method eases the manipulation of nanostructures while providing geometrical uniformity.Type: GrantFiled: October 9, 2003Date of Patent: March 24, 2009Assignee: Massachusetts Institute of TechnologyInventors: Sang-Gook Kim, Tarek A.

Patent number: 7465381Abstract: A method for separation of mixtures in fluidic systems through electrokinetic transport by use of nanochannels when the fluidic systems approach the size of an electrical double layer, thereby allowing separation based on charge. The disclosed apparatus comprises a T-chip with a nanochannel section. The method and apparatus are useful for separation of many molecular species, including peptides, proteins, and DNA.Type: GrantFiled: October 4, 2004Date of Patent: December 16, 2008Assignee: STC.UNMInventors: Gabriel P. Lopez, Steven R. J. Brueck, Linnea K. Ista, Anthony L. Garcia, Dimiter N. Petsev, Paul Bisong, Michael J. O'Brien

Publication number: 20080269083Abstract: The invention relates to a method of treating permeable rocks wherein the following stages are carried out: producing particles of nanometric size comprising an active anti-mineral-deposit water-soluble polymer encapsulated in either a matrix so as to form a nanocomplex or a nanosphere, or in a membrane so as to form a nanocapsule; maintaining an amount of said particles dispersed in a liquid phase; injecting the dispersion into the permeable rock; and releasing the active polymer upon contact with salt water.Type: ApplicationFiled: February 6, 2006Publication date: October 30, 2008Inventors: Jean-Francois Argillier, David Pasquier
