In this paper we extend our study on the effect of gas flow rate and synthesis time on horizontal multi-wall carbon nanotube (MWCNT) growth and morphology synthesized from methane by double-heater thermal catalytic vapor deposition method (TCVD) using a mixture of methanol and ammonia as active agents to promote the growth of nanotubes. Nickel was used as a catalyst. The prepared nanotubes were characterized...
In this article the effect of catalyst thickness and reaction temperature on the formation of horizontal multi-wall carbon nanotube (MWCNT) was discussed to control product growth and morphology. MWCNTs were synthesized from methane by double-heater thermal catalytic vapor deposition method (TCVD) using a mixture of methanol and ammonia as active agents to promote the growth of nanotubes and nickel...
Using piezoelectric elements to harvest energy from ambient vibration and human motion has been of great interest recently. This study quantifies the amount of energy generated by piezoelectric device from vibration environment and human motion. Nickel metal hydride rechargeable battery has been used to store the energy generated. Throughout the experiment, the discharged 40m Ah rechargeable battery...
