Publication number: 20130202582Abstract: The present invention provides a composition for selectively delivering an active agent to a portion of an organism. The composition comprises first and second polymer portions, having first and second functional groups attached as a side-chain thereto, respectively. The first and second functional groups form cross-links between the first and second polymer portions. The cross-links are capable of being broken by a substance of the organism, thereby resulting in release of the active agent.

Publication number: 20110294296Abstract: The present invention provides a method for manufacturing a structure over a semiconductor substrate. To form a trench, a patterned layer is formed on a portion of a substrate such that the patterned layer forms a target area located adjacent an edge of the patterned layer. A self-assembled monolayer (SAM) is coupled to the substrate up to the patterned layer, but excluded from the patterned layer. The substrate is then removed within the target area. A wire is formed in a similar fashion except that the first SAM is exchanged with a second SAM in the target area. Then either the substrate outside of the target area is removed, or conductive metal crystals are grown within the target area. Such structures may be advantageously used in the manufacture of a number of active or passive electronic devices, such as a field effect transistor.Type: ApplicationFiled: May 21, 2003Publication date: December 1, 2011Applicant: Lucent Technologies Inc.Inventors: Joanna Aizenberg, Vikram Sundar

Publication number: 20100247982Abstract: A battery having an electrode with at least one nanostructured surface is disclosed wherein the nanostructured surface is divided into cells and is disposed in a way such that an electrolyte fluid of the battery is prevented from contacting the portion of electrode associated with each cell. When a voltage is passed over the nanostructured surface associated with a particular cell, the electrolyte fluid is caused to penetrate the nanostructured surface of that cell and to contact the electrode, thus activating the portion of the battery associated with that cell. The current/voltage generated by the battery is controlled by selectively activating only a portion of the cells. Multiple cells can be active simultaneously to produce the desired voltage. The more cells that are active, the higher the current/voltage and the lower the overall life of the battery. The life of the battery can be extended by activating fewer cells simultaneously.Type: ApplicationFiled: June 11, 2010Publication date: September 30, 2010Applicant: Lucent Technologies Inc.Inventors: Marc Scott Hodes, Paul Robert Kolodner, Thomas Nikita Krupenkln, Alan Michael Lyons, Mary Louise Mandich, Joseph Ashley Taylor, Donald Weiss

Publication number: 20100221597Abstract: A battery having a nanostructured battery electrode is disclosed wherein it is possible to reverse the contact of the electrolyte with the battery electrode and, thus, to return a battery to a reserve state after it has been used to generate current. In order to achieve this reversibility, the nanostructures on the battery electrode comprise a plurality of closed cells and the pressure within the enclosed cells is varied. In a first embodiment, the pressure is varied by varying the temperature of a fluid within the cells by, for example, applying a voltage to electrodes disposed within said cells. In a second illustrative embodiment, once the battery has been fully discharged, the battery is recharged and then the electrolyte fluid is expelled from the cells in a way such that it is no longer in contact with the battery electrode.Type: ApplicationFiled: May 6, 2010Publication date: September 2, 2010Applicant: Lucent Technologies Inc.Inventors: Marc Scott Hodes, Paul Robert Kolodner, Timofei Nikita Kroupenkine, Alan Michael Lyons, Mary Louise Mandich, Joseph Ashley Taylor, Donald Weiss
