Hydrothermal microwave method (HTMW) was used to synthesize crystalline zinc oxide (ZnO) nano-columns at the temperature of 120 degrees C with a soaking time of 8 min. ZnO nano-columns were characterized by using X-ray ...

The effect of O2 +, H2 ++ O2 +, and N2 ++ O2 +ion-beamirradiation of carbon nanotubes(CNTs) films on the chemical and electronic properties of the material is reported. The CNTs were grown by the chemical vapor deposition ...
