Vertically aligned nitrogen-doped carbon nanotubes (NCNTs) with uniform size distribution, large aspect ratio, good orientation, and high purity were employed as novel platforms to understand the dopant-induced perturbations and found widely applications in catalysis, electrochemistry, energy conversion and storages. However, the efficient way to synthesis CNTs with ordered alignment in large scale...
Superstrong, ultralong, individual carbon nanotubes (CNTs) are deposited with TiO2 particles and visualized under an optical microscope with excellent strain‐relaxation reversibility and high fatigue resistance capability. The CNTs with perfect structures have tensile strengths of up to 200 GPa, densities to 1.34 TPa, energy density as high as 1125 Wh kg−1 and the power density can be up to 144 MW...
In this paper, vertically aligned carbon nanotube (CNT) emitters on nickel film were synthesized by microwave plasma chemical vapor deposition for large current field emission applications. The as-grown CNT arrays were characterized using scanning electron microscopy (SEM). Also the field emission current density against applied voltage and the F-N plot of plasma etched CNTs were measured
