Coherent G-mode vibrations in SWNTs were studied with spectrum-resolved pump-probe experiments. Detection wavelength dependence of G-mode amplitude was explained by SARS and SSRS. We could drive one process by controlling the dispersion of ultrashort pulses.
This paper reports chemical vapor deposition (CVD) of carbon nanotube arrays at substrate temperatures lower than 100degC and growth rates greater than 50 mum/h using atmospheric plasma discharges inside microcapillary reactors. Thermal CVD using the same reactor required temperatures in excess of 900degC. At temperatures greater than 1100degC, the thermal CVD yielded an unusual, diverging conical...
Coherent G-mode vibrations of single-walled carbon nanotubes are observed in the spectrum-resolved pump-probe measurements. The G-mode oscillation is relatively strong in the edge side of the laser spectrum while being weak for the central region.
Nanomaterials have attracted considerable attention from researchers, since the discovery of carbon nanotubes by Iijima. Due to their peculiar structural characteristics and size effects, nanomaterials exhibit some novel physical properties that are different from those of the bulk materials. In this work, we described a synthesis method of cadmium oxide (CdO), zinc oxide (ZnO) and carbon black (CB)...
Summary form only given. This study demonstrates the hydrophobic coating by methane (CH4) glow discharge plasma at low-pressure and investigates the superhydrophobic behavior of the treated carbon nanotubes (CNTs). Carbonaceous species produced from the CH4 glow plasma were identified by an optical emission spectroscopy. The treated CNTs have floated on water for several months, exhibiting hydrophobic...
