A viewer asked a great question:

“You mentioned atmospheric plasmas and plasmas in vacuum. Do people research pressurized plasmas?”

In this video, I break down how pressure affects plasma behavior and why researchers work across a huge range of pressures—from high vacuum plasmas used in semiconductor manufacturing, to atmospheric-pressure plasmas used for medicine and environmental applications, and even high-pressure plasmas studied in physics and industry.

Pressure changes how plasmas form, how energy moves  ...
