Shake, rattle & roll

Uniform plasma treatment of micron-sized particles can be challenging because the particles need to be suspended in the plasma discharge.  What does this have to do with a common stereo speaker playing music or a rotating apparatus commonly used for purifying organic chemical compounds?

Shake, rattle & roll.

Putting the particles on top of a speaker playing music shakes and rattles the particles in the plasma discharge and allows them to be evenly coated.

Or, tumbling the particles in a rotating flask containing the plasma discharge rolls them around and gives them an even coating.

These are the two ideas behind our new publication from Wark and Mawson Institute researchers in Plasma Processes and Polymers:

Capture

Common laboratory or household equipment can be readily adapted to plasma discharge apparatus creating a low-cost, yet effective way to solve the challenge of depositing plasma coatings on small particles.
