Monometallic and bimetallic Ni and Co catalytic nanoparticles supported on Titanium dioxide (rutile phase) substrate were prepared by wet impregnation method. These nanoparicles were used as catalysts for synthesis of multiwalled carbon nanotubes (MWCNTs) from acetylene decomposition at 700°C by the catalytic chemical vapor deposition (CCVD) technique. The nanomaterials (catalyst and CNTs) were...

Aligned Carbon Nanotubes For Multifunctional Nanocomposites and Nanodevices L Dai, L Qu (Univ of Dayton) We have previously developed a simple pyrolytic method for large-scale production of aligned carbon nanotube arrays perpendicular to the substrate. These aligned carbon nanotube arrays can be transferred onto various substrates of particular interest in either a patterned or non-patterned fa...

In this work, we studied the electro-optical properties of high-aligned carbon nanotubes deposited at room temperature. For this, we used the High Density Plasma Chemical Vapor Deposition system. This system uses a new concept of plasma generation: a planar coil is coupled to an RF system for plasma generation. This was used together with an electrostatic shield, for plasma densification, there...

It is shown by the method of molecular dynamics using a chain model that multilayer packaging identical single-walled carbon nanotubes with diameter D > 2.5 nm located on flat substrate multistable system. The system has many stationary states, which are characterized portion collapsed nanotubes. thickness package monotonically decreases an increase in such For chirality index (60,0), depending...
