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 [...]

Multi-Scale Modeling of Processing of Carbon Nanotubes

Choi H.S., Kim J., Kim K.H., Hong K-H, Kim J., Kim K.H., Lee H.S., Shin J-K, Vasenkov A.V., Fedoseyev A.I., Kolobov V., Samsung Advanced Institute of Technology, KR

The current rapid development of nanotechnology has created a significant interest to predict the behavior of materials from the atomic to the engineering scales. However, it was found that such prediction is a very challenging [...]

Large Scale Nanocarbon Simulations

Tejima S., Iizuka M., Park N., Berber S., Nakamura H., Tomanek D., Research Organization for Information Science & Technology, JP

The mechanical response of carbon nanotubes to revere deformation has attracted much attention since their discovery in 1991. Carbon nanotubes have already demonstrated exceptional mechanical properties: their excellent flexibility during bending have been observed experimentally. [...]

Interactions between Carbon Nanotubes and Liquids: Imbibition and Wetting

Cuenat A., Whitby M., Cain M., Mendels D., Quirke N., National Physical Laboratory, UK

Carbon nanotubes (CNT) have potential applications in nanofluidic devices and are already in use for composite reinforcement. Their interactions with fluids are critical in both those applications. Furthermore, the wetting dynamics of homogeneous and structured [...]
