Computing Encapsulation of Non-metallic Molecules: N2@C60

Slanina Z., Nagase S., Institute for Molecular Science, JP

Recent observation of N2@C60 is supported computationally. The geometry is optimized at the B3LYP/3-21G and PW91/3-21G levels. The lowest-energy structure has the N2 unit oriented towards a pair of parallel pentagons so that the complex [...]

The Structure and Properties of ta-C Film with Dispersion of Incident Beam Energy

Lee K-R, Lee S-C, Lee S-H., Kim T.-Y., Lee K-R, Lee S-C, Lee S-H., Chung Y-C, Brenner D.W., Lee K-R, Lee S-C, Lee S-H., Korea Institute of Science and Technology, KR

We investigated the structural properties of ta-C film as a function of the dispersion in the incident kinetic energy. The ta-C films were produced on a diamond (100) surface by the bombardment of 3, 000 [...]

Hybrid Nanomaterials for Active Electronics and Bio-Nanotechnology

Wang X., Pandey R.R., Lake R., Ozkan C.S., University of California Riverside, US

We describe self assembly processing of functional carbon nanotubes using single strand deoxyribonucleic acid (DNA) and peptide nucleic acid (PNA) fragments. Previous research has shown the self assembly of carbon nanotubes to quantum dots via [...]

Structural Study of Amorphous Carbon using Adaptive Interatomic Reactive Empirical Bond-order Potential Model

Knippenberg M.T., Kum O., Stuart S.J., Clemson University, US

We studied the structural properties of amorphous carbon covering a wide range of densities from low-density to high-density regime using classical molecular dynamics with reactive empirical bond-order potential model. We calculated the pair-correlation functions, relative [...]

Effects of the Process Parameters on the Carbon Nanotubes Growth by Thermal CVD

Verissimo C., Moshkalyov S.A., Ramos A.C.S., Gonçalves J.L., Alves O.L., Swart J.W., CCS - UNICAMP, BR

Carbon nanotubes growth was performed by thermal chemical vapor deposition using a tubular furnace and methane as carbon feedstock gas. Thin films of nickel were employed as catalysts supported onto a SiO2/Si substrate. The influence [...]

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 [...]

Continuous Mass Production of Fullerenes and Fullerenic Nanoparticles by 3-Phase AC Plasma Processing

Fabry F., Gruenberger T.M., Gonzalez-Aguilar J., Okuno H., Grivei E., Probst N., Fulcheri L., Flamant G., Charlier J-C, TIMCAL Belgium S.A., BE

A patented plasma technology has been developed over the last ten years for the continuous mass production of fullerenes and fullerene soot by the core partners of a consortium (TIMCAL BELGIUM S.A., EMP-ARMINES and CNRS). [...]

Near-Field Electrodynamics of Atomically Doped Carbon Nanotubes

Bondarev I.V., Lambin Ph., The Belarusian State University, Minsk, BY

We have developed a quantum theory of near-field electrodynamical properties of carbon nanotubes. The theory was used to investigate spontaneous decay dynamics and van der Waals attraction of a single two-level atom close to a [...]

Amorphous Diamond Electron Emission for Thermal Generation of Electricity

Sung E., Sung J.C-M, Sung M., Kan K., Sung E., Sung J.C-M, Sung M., Huang J-L, Sung E., Sung J.C-M, Sung M., Chen C-P, Hsu K-H, Tai M-F, Kinik Company, TW

Amorphous diamond represents a class of material of its own. It may be viewed to be a composite of metal (graphite) and insulator (diamond), but together they form a unique passage for electrons to flow [...]

Role of Nanoscale Topography on the Hydrophobicity: A Study of Fluoro-Based Polymer Film on Carbon Nanotubes

Phani A.R., Lozzi L., Passacantando M., Santucci S., University of L'Aquila, IT

The unique electronic, mechanical and chemical properties of carbon nanotubes making them most promising candidate for the building blocks of molecular-scale machines, and nanoelectronic devices. On the other hand, highly hydrophobic films are being actively [...]
