Using C2H2, 112 and As gases at 550'C, carbon nanotubes were fabricated on the surfaces of twosubstrates coated by nano thin layers of metal catalysts by DC magnetron sputtering. AYStamless steel andFe/CteAl, by thermal chemical vapor deposition (TCVD) The surface properties of the substrates wereparticularly investigated, and the effect of treatment of the substrates on the CNT's growth is cri...

The micro and nano-structured amorphous carbon as p-type films prepared from natural palm oil precursor for heterojunction solar cell were presented. Field-emission scanning electron microscopy (FESEM) revealed the micro and nano structured films had particle size in the range of 382 nm to 689 nm and 28 to 34 nm, respectively. The energy-dispersive spectroscopy (EDS) showed the existing of carb...

In this work, the microwave surface wave plasma (MWSWP) equipment is used to grow the carbon nano-materials at low temperature on different catalysts prepared by the so-called plasma assisted sol-gel synthesis method. Without any additional heating method, the plasma itself can heat up the substrate to about 280oC. By applying the -600V bias voltage, the substrate temperature can reach more tha...

Objective To compare the accuracy and feasibility of methylene blue and nano-carbon in clinical tracing of sentinel lymph nodes (SLNs) in patients with papillary thyroid cancer (PTC). Methods Ninety-six PTC patients were selected and randomly divided into a methylene blue group and a nano-carbon group (n=48). During surgery, tracer agent was injected around the tumor, and SLNs were resected a...

The complex and nano-structured amorphous carbon as p-type films prepared from natural palm oil precursor for heterojunction solar cell were presented. Field-emission scanning electron microscopy (FESEM) revealed the nano structured films had particle size in the range of 28 to 34 nm. The energy-dispersive spectroscopy (EDS) showed the existing of carbon in complex-structured amorphous carbon f...

A nano-composite powder composed of silica and carbon with a unique property could be prepared from a mixture of a silicate compound and an epoxy compound, in which the silica within the nano-composite powder has a BET surface area of as high as greater than 800m2/g although the nano-composite powder has a BET surface area of less than 10m2/g. It was estimated that the silica and the carbon are...

This paper presents the friction and anti-wear characteristics of nano-oil with a mixture of refrigerant oil and carbon nano-particles in the thrust slide-bearing of scroll compressors. Frictional loss in the thrust slide-bearing occupies a large part of total mechanical loss in scroll compressors. The characteristics of friction and anti-wear using nano-oil is evaluated using a thrust bearing ...

The stability of Ni, Cu, Mo and Au transmission electron microscope (TEM) grids coated with ultra-thin amorphous carbon (alpha-C) or silicon monoxide film is examined by in-situ heating up to a temperature in the range 500-850 degrees C in a transmission electron microscope. It is demonstrated that some grids can generate nano-particles either due to the surface diffusion of metal atoms on amor...

in this work the synthesis of polyaniline/chitosan/functionalized single- walled carbon nanotube nanocomposite is carried out. for this purpose single -walled carbon nanotubes were reacted with thionyl chloride to change the hydroxyl to acyl chloride groups for improving the react ability. in other step, aniline monomers and chitosan were polymerized in the presence of iron (iii) chloride to sy...
