Publication number: 20150308018Abstract: The present invention is directed to nanofiber yarns, ribbons, and sheets; to methods of making said yarns, ribbons, and sheets; and to applications of said yarns, ribbons, and sheets. In some embodiments, the nanotube yarns, ribbons, and sheets comprise carbon nanotubes. Particularly, such carbon nanotube yarns of the present invention provide unique properties and property combinations such as extreme toughness, resistance to failure at knots, high electrical and thermal conductivities, high absorption of energy that occurs reversibly, up to 13% strain-to-failure compared with the few percent strain-to-failure of other fibers with similar toughness, very high resistance to creep, retention of strength even when heated in air at 450° C. for one hour, and very high radiation and IJV resistance, even when irradiated in air. Furthermore these nanotube yarns can be spun as one micron diameter yarns and plied at will to make two-fold, four-fold, and higher fold yarns.Type: ApplicationFiled: July 16, 2014Publication date: October 29, 2015Applicants: BOARD OF REGENTS, THE UNIVERSITY OF TEXAS SYSTEM, Commonwealth Scientific and Industrial Research OrganisationInventors: Mei Zhang, Shaoli Fang, Ray H.

Publication number: 20150040888Abstract: An objective of the invention is to design and develop an effective method to collect and store heat in a solar collector for delayed release. An embodiment of the invention is directed to an evacuated tube collector, where PCM is placed directly inside the void space of the collector tube, next to the heat pipe. The heat pipe is located with phase change material (PCM) in such a way that its thermal connection with the heat pipe can be switched “ON” to start heat transfer from PCM or “OFF” to keep latent heat stored in PCM for delayed usage. In additional, flow of heat exchange fluid through the manifold can enable release of stored heat of PCM to storage tank. Delayed release of accumulated heat in PCM enables added functionality of on-demand operation of SWH.Type: ApplicationFiled: August 8, 2014Publication date: February 12, 2015Inventors: Anvar A.

Publication number: 20130240027Abstract: A tandem (or multijunction) hybrid photovoltaic device (PV) device comprised of multiple stacked single PVs connected in parallel with each other is described herein. Furthermore, nanomaterials are used as transparent charge collecting electrodes that allow both parallel connection via anode interlayer and also “inverted parallel” connection via cathode type interlayer of different types of solar cells. Carbon nanotube sheets are used as a convenient example for the charge collecting electrodes. The development of these alternative interconnecting layers simplifies the process and may be also used for combined organic PVs with traditional inorganic PVs and Dye Sensitized Solar Cells (DSSC). In addition, novel architectures are enabled that allow the parallel connection of the stacked PVs into monolithic multi-junction PV tandems. This new monolithic parallel connection architecture enables enhanced absorption of the solar spectrum and results in increased power conversions efficiency.Type: ApplicationFiled: June 7, 2011Publication date: September 19, 2013Applicants: Solarno, Inc., The Board of Regents of the University of Texas SystemInventors: Anvar A.

Publication number: 20130240847Abstract: A tandem organic light emitting diode (OLED) device comprised of multiple stacked single OLEDs electrically connected in parallel via transparent interlayer is recited herein. Transparent interlayers are coated by charge injection layers in order to enhance the charge injection efficiency and decrease the operation voltage. Transparent nanomaterials, such as carbon nanotube sheets (or graphene, graphene ribbons and similar conductive transparent nano-carbon forms) are used as Interlayers or outer electrodes. Furthermore, functionalization of carbon nanotubes inter layers by n-doping (or p-doping) converts them into common cathode (or common anode), further decreasing operation voltage of tandem. The development of these alternative interconnecting layers comprised of nanomaterials simplifies the process and may be combined with traditional OLED devices. In addition, novel architectures are enabled that allow the parallel connection of the stacked OLEDs into monolithic multi-junction OLED tandems.Type: ApplicationFiled: May 21, 2011Publication date: September 19, 2013Applicants: Solarno, Inc., The Board of Regents of the University of Texas SystemInventors: Anvar A.

Patent number: 7247290Abstract: Coagulation spinning produces structures such as fibers, ribbons, and yarns of carbon nanotubes. Stabilization, orientation, and shaping of spun materials are achieved by post-spinning processes. Advantages include the elimination of core-sheath effects due to carbonaceous contaminants, increasing mechanical properties, and eliminating dimensional instabilities in liquid electrolytes that previously prohibited the application of these spun materials in electrochemical devices. These advances enable the application of coagulation-spun carbon nanotube fibers, ribbons, and yarns in actuators, supercapacitors, and in devices for electrical energy harvesting.Type: GrantFiled: November 4, 2003Date of Patent: July 24, 2007Assignee: Honeywell International Inc.Inventors: Alex Lobovsky, Jim Matrunich, Mikhail Kozlov, Robert C.
