The geometrical structure of carbon nanotubes has been calculated and analyzed in this paper. The analysis of carbon nanotube for Pz orbital, perpendicular to the graphene sheet and thus the nanotube surface forms a delocalized π network across the nanotube, which is responsible for its electronic properties. These electronic properties are obtain

The present paper reports on the influence of process parameters on surface quality of mild steel during EDM using a copper electrode. Surface quality was evaluated on the basis of work surface roughness, micro cracks and thickness of the recast layer. Current, pulse-on time, pulse-off time and voltage were the variable parameters for the present i

In this paper, a Matlab simulator is developed for modelling of carbon Nanotubes (CNTs). First electronics structure is derived and discussed to facilitate the analysis and modelling of the simulator. Then a calculation is done for electron energy dispersion relations for single-wall zigzag CNTs with different tube indexes. From the analysis of ene

In this paper, graphene electronic structure of carbon nanotubes has been analyzed and validate with past theoretical and experimental results. The energy dispersion relation, effective mass and intrinsic carrier concentration of graphene have been analyzed to build diverse carbon nanotubes. The electronics properties of graphene are subject to cha

In the present study the effect of electrode size and discharge current on material removal rate (MRR) and wear ratio (WR) during electrical discharge machining has been investigated. The work and electrode materials were mild steel and copper respectively. The diameters of the cylindrical electrodes were 9, 15, 20 and 30 mm. Experiments were condu

In the present study a special device has been designed to apply liquid nitrogen coolant during turning of AISI 304 stainless steel. The base of the device is a magnet and it can be fixed at any suitable position on the tool or tool post. A long flexible and adjustable copper nozzle is used to apply liquid nitrogen at any angle or from any position

This paper suggests the modeling phenomena of small band-gap Carbon Nanotube (CNT). Device physics of CNT is studied and do the calculation of sub-band for zigzag CNT to model small band-gap tubes. Each carbon nanotube is described as a graphene sheet rolled into a cylindrical shape so that the structure is one dimensional with axial symmetry. A co
