Functionalized Carbon Nanotube–Based Sensors for Detecting a Trace Quantity of 2,4-Dinitrotoluene Explosive Vapors, with Selectivity

Kayastha V., Jones C., Landorf C., Brewer Science, Inc, US

We have developed a new sensing material that can selectively detect explosive molecules such as 2,4-dinitrotoluene and 2,4,6-trinitrotoluene; and have successfully demonstrated functional chemical sensors using this new material. The newly developed sensing material is [...]

A Novel Catalytic Synthesis Method of Carbon Nanomaterials in the Organic Liquids

Gamo H., Nishitani-Gamo M., Ando T., Nishitani-Gamo M., Toyo University, JP

We have developed a novel catalytic method for synthesizing a wide variety of carbon nanomaterials in the organic liquids. There is no need for a vacuum reactor. The method realized a simple, speedy, and a [...]

Growth of Uniform CNT Layer on Copper Foil-the Effect of Synthesis Methods/Conditions

Zhang Q., Scofield J., Tsao B., Merrett J.N., Quinton B.T., Burke J., Pierce N., University of Dayton, US

Carbon nanotubes (CNTs) with unique thermal/electrical/mechanical properties and large surface area are an attractive candidate for the integration into thermal structures and for a flexible thermal interface material in a thermal device. In this study, [...]

Hollow core-shell structured mesoporous MWCNT/carbon nanofiber composites by electrospinning and silica template as counter electrodes for dye-sensitized solar cells

Park S.H., Kim B-K., Lee W.-J., Chonnam National University, KR

The multi-walled carbon nanotube (CNT)-embedded carbon nanofibers with hollow core/highly mesoporous shell stucture (CNT/Meso-HACNF) are prepared by concentric electrospinning using poly(methyl methacrylate) (PMMA) as a pyrolytic core precursor with either CNT/polyacrylonitrile (PAN) or fumed silica [...]

Novel nanocarbon-based, lightweight, flexible EMI shield

Strobl K., Monville M., Banerjee S., Chang S., Jayasinghe C., Sprengard J., CVD Equipment Corporation, US

The EMI shielding capability of a material depends primarily on its electrical conductivity, its magnetic permeability, the frequency of an electromagnetic wave of interest, the total surface area of the material and its thickness related [...]

Carbon Nanostructured Advanced Cable Shielding Technologies

Harvey S., Shah T., Dutton P., Morber J., Lockheed Martin, US

Applied NanoStructured Solutions, LLC (ANS) has developed a technology to continuously grow and infuse Carbon Nanostructures (CNS) directly on fiber substrates. ANS has designed and constructed a modular, scalable manufacturing line and demonstrated infusion onto [...]

The Effect of Thermal Annealing Processes on Graphene

Kumar K., Kim Y-S, Li X., Tian Y., Pallikaras A., Yang E.H., Stevens Institute of Technology, US

We demonstrate the impact of PMMA removal from CVD graphene by annealing in H2/Ar and ambient atmospheres as well as under vacuum on the Raman spectra and AFM topography of graphene. We find a broad [...]
