For surface modification using low-pressure plasma, a vacuum chamber containing partially ionized gas is used, with the material placed inside the chamber for treatment. Specialized pumps maintain ...

Now, researchers have developed an improved gas-sensing technology by treating graphene sheets with plasma under different conditions, creating structural and chemical defects that enhance ammonia ...

A group of scientists has developed special CO2-derived carbon nanotubes that can generate sustained plasma almost ... approach requires no vacuum chambers, no controlled gas environment, and ...
