In this work, oxygen-containing groups were introduced onto multiwall carbon nanotubes (MWCNTs) by using microwave-excited Ar/O 2 surface-wave plasma (SWP) treatment. The changes of the atomic ...

Witness how we built a versatile cutting machine that combines the power of a plasma cutter and a circle track, allowing me to make precise cuts on metal with both plasma and gas burners. To create ...
