Experimental Observation of Carbon and Carbon-Metal Nanotoroids and New Carbon-Metal Superstructures at Nanoscale

Kislov V., Medvedev B., Taranov I., Russian Academy of Sciences, RU

We report experimental observation (by AFM, STM and HRTEM methods) of nanotoroids for both carbon and carbon-metal superstructures produced by methods of arc discharge and laser ablation. Size of superstructures is ~ 10 nm for [...]

Development of a Biologically Enhanced Carbon Nanotube Based Composite

Parker R., O’Neal R., Fisher D., Davey Kirk, Liang R., Edwards J., Florida A&M University, US

Composite materials continue to be important to the evolution of human space flight activity. The low weight/high strength ratio and thermal properties of carbon based composite materials in particular that make them well suited for [...]

Supramolecular Self-assembly of Carbon Structures from Shungite Rock Using Only Water

Osipov E., Osipov S., Reznikov V., Osipov E., Osipov S., Shestakov Yu., Satakunta Polytechnic, Technology, Pori, Finland, FI

In spite the fact that fullerene and any type of carbon are not soluble in water the main goal of this work is to produce evidence of realization of a supramolecular self-assembly of carbon structures [...]

Structural and Mechanical Properties of Double Wall Carbon Nanotubes

Bacsa R.R., Bacsa W.S., Flahaut E., Laurent Ch., Peigney A., Puech P., Bacsa R.R., Bacsa W.S., LPST Université Paul Sabatier, FR

Narrow diameter double walled carbon nanotubes can now be grown by the catalytic chemical vapor deposition process with high yield. Double walled carbon nanotubes are the molecular analogs to coaxial cables and they can also [...]

Fabrication of Nanopipes using Vertically Aligned Carbon Nanofiber Templates and their Properties

Melechko A.V, McKnight T.E., Guillorn M.A., Ilic B., Merkulov V.I., Doktycz M.J., Warmac B., McCorkle D., Lowndes D.H., Simpson M.L., University of Tennessee, Knoxville, US

Fluidic structures with submicron dimensions have potential applications for sorting DNA molecules, electroanalytical sensing, and detecting and characterizing single molecule events. The fabrication of devices that function on the nanometer scale requires new approaches when [...]

MonteCarlo Simulations of Carbon-based Structures Based on Extended Brenner Potential

Petukhov A.V., Fasolino A., Research Institute for Materials, Institute of Theoretical Physics, University of Nijmegen, NL

Extended grand-canonical off-lattice Monte Carlo simulations of the (100) and (111) diamond surfaces have shown that the Brenner potential is extremely accurate in describing the structural properties at surfaces, supporting the recent predictions of new [...]
