A high energy density supercapacitor device is reported that utilizes hybrid carbon electrodes and the ionic liquid, 1-butyl-3-methylimidazolium tetrafluoroborate (BMIMBF 4) as an electrolyte. The hybrid electrodes are prepared from reduced graphite oxide (rGO) and purified single-walled carbon nanotubes (SWCNTs). A simple casting technique gives the hybrid structure with optimum porosity and functionality that provides high energy and power densities. The combination of SWCNTs and rGO in a weight ratio of 1:1 is found to afford a specific capacitance of 222 F g -1 and an energy density of 94 Wh kg -1 at room temperature. © 2012 WILEY-VCH Verlag GmbH & Co.

We report the use of chemically functionalized water-soluble single-walled carbon nanotubes (ws-SWCNTs) for the modulation of morpho-functional characteristics of astrocytes. When added to the culturing medium, ws-SWCNTs were able to make astrocytes larger and stellate/mature, changes associated with the increase in glial fibrillary acidic protein immunoreactivity. Thus, ws-SWCNTs could have more beneficial effects at the injury site than previously thought; by affecting astrocytes, they could provide for a more comprehensive re-establishment of the brain computational power. © 2012 American Chemical Society.

We used single-walled carbon nanotube (CNT) films to modulate the morpho-functional and proliferative characteristics of astrocytes. When plated on the CNT films of various thicknesses, astrocytes grow bigger and rounder in shape with a decrease in the immunoreactivity of glial fibrillary acidic protein along with an increase in their proliferation, changes associated with the dedifferentiation of astrocytes in culture. Thus, CNT films, as a coating material for electrodes used in brain machine interface, could reduce astrogliosis around the site of implantation. © 2013 American Chemical Society.

An acid-impregnated activated carbon matrix is formed from a carbonaceous material by the addition of a mineral acid, and may be used to chemisorb ammonia from a gas stream. The ammonia reacts with the acid to form a fertilizer salt. The spent matrix may be used as a fertilizer, or the fertilizer salt may be elutriated from the matrix.

Systems and methods for the purification of carbon nanotubes (CNTs) by continuous liquid extraction are disclosed. Carbon nanotubes are introduced to a flow of liquid that enables the separation of CNTs from impurities due to differences in the dispersibility of the CNTs and the impurities within the liquid. Examples of such impurities may include amorphous carbon, graphitic nanoparticles, and metal containing nanoparticles. The continuous extraction process may be performed in one or more stages, where one or more of extraction parameters may be varied between the stages of the continuous extraction process in order to effect removal of selected impurities from the CNTs. The extraction parameters may include, but are not limited to, the extraction liquid, the flow rate of the extraction liquid, the agitation of the liquid, and the pH of the liquid, and may be varied, depending on the impurity to be removed from the CNTs.

New material systems are required as a result of advanced performance criteria for the next generation destroyer program and other Navy ships. As a part of these requirements there is high demand for high strength structural composites. The objective of the STTR Phase II project is to develop high strength and light weight structural composites utilizing functionalized single-walled carbon nanotubes (SWNTs) as a nanoscale reinforcement. We propose to significantly increase the out-of-plane mechanical properties of the carbon fiber/epoxy composites by the introduction of SWNTs; SWNTs are considered to be the ideal reinforcing agent for advanced polymer composites because of their tremendous mechanical strength, exceptional electronic and thermal properties, nanometer scale diameter, high aspect ratio and light weight. Our approach is to apply chemistry to modify the SWNTs and engineer the interfacial interaction with the resins, because the formation of a strong interface is a critical step in the efficient translation of the excellent mechanical properties of SWNTs into the composite materials. In Phase I of this STTR project we demonstrated the feasibility of utilizing chemically modified SWNTs for the VARTM fabrication of carbon fiber/epoxy composites and showed that the incorporation of SWNTs improved shear strength and preserved in-plane mechanical properties.

Agency: Department of Defense | Branch: Army | Program: SBIR | Phase: Phase I | Award Amount: 100.00K | Year: 2013

This project aims to develop all-solid-state hybrid energy storage devices with flexible nanostructured electrode materials combined with a polymer electrolyte. The hybrid devices utilize a capacitor-like electrode based on graphene and carbon nanotubes and a battery-like electrode, comprised of nanostructured LiFePO4 grown on a graphene support. The proposed device combines the advantages of anode, cathode and electrolyte to deliver energy densities>100 Wh/kg, maintain power densities above 1 kW/kg and provide longer life cycle than a typical rechargeable battery. The proposed approach extends to the conformal fabrication of current collectors, electrodes and electrolyte which allow the hybrid devices to be integrated in the next generation of electronic devices.
