Layer-on-layer Assembly of Macroscopic 2D and 3D Carbon Nanomaterial Architectures

Patel S.C., Lalwani G., Alam O., Grover K., Qin Y-X, Sitharaman B., Stony Brook University, US

Although carbon nanomaterials are often labeled as the future replacement for silicon in electronics and a new generation of robust materials, there are major shortcomings in the assembly of carbon nanomaterials into higher order structures. [...]

Advancements in Microelectronics-Grade Carbon Nanotube Materials for NRAM® Device Manufacture and Analysis of Carbon Nanotube Mass in End User Devices

Lamb J.E., Gibbons S., Trichur R., Jiang Y., Mangelson K., Kremer K., Janzen D., Brewer Science, Inc, US

Providing materials for use in semiconductor manufacturing is challenging due to the extreme quality levels required for low metal ion and defect levels. This challenge is much greater for suppliers of materials containing long, high-aspect-ratio [...]

Chemoselective Hydrogenolysis of Glycerol Catalyzed by Platinum on Carbonaceous Supports

Oberhauser W., Evangelisti C., Psaro R., Vizza F., Bevilacqua M., Filippi J., Lavacchi A., Marchionni A., Miller H.A., Machado B.F., Serp P., CNR-ICCOM, IT

Glycerol has been selectively converted into 1,2-propandiol in the presence of dihydrogen and heterogeneous Pt-based catalysts. These latter catalysts consist of small-size Pt-nanoparticles (NPs) (i.e. 1.0-1.5 nm,) obtained by a metal vapor synthesis, supported on [...]

Renewable Energy Technology Gains by Interfacial Engineering with Carbon Nanomaterials

Vander Wal R.L., The Pennsylvania State University, US

Creating a new paradigm, nanomaterials, when used as interfacial modifiers have the potential to significantly alter the energy landscape, given that these processes occur predominantly at interfaces. The key concept is that the nanomaterials serve [...]

Nanocarbon Nanofluids: Comparisons Between Morphology and Nanostructure

Vander Wal R.L., The Pennsylvania State University, US

Reported here are experimental results of studies designed to identify the operable mechanisms responsible for the gains in thermal conductivity of nanoﬂuids based on nanocarbons. Comparison of functionalized versus nonfunctionalized nanocarbons addresses the effect of [...]

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 [...]

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 [...]

Novel Carbon-Aluminum Materials

Jasiuk I., Nilufar S., Salamanca-Riba L., Isaacs R., Siddiqi S., University of Illinois at Urbana-Champaign, US

We characterized novel metal carbon materials called covetics. More specifically we study warm rolled Al 7075-carbon materials containing up to 5 wt% C. At macroscale we measured mechanical properties: Young’s modulus, ultimate tensile strength (UTS), [...]
