Additional information

In collaboration with Queens University and the Institute of Physics (Serbia), we demonstrate the smallest reported non-equilibrium (low temperature) RF plasma operating in steady-state. With a 25 micron hollow cathode structure and a deposited power density greater than 10 MW/litre, this device indicates the potential for scaling into dimensional regimes that are as yet unexplored. This achievement helped secure subsequent EPSRC funding for microplasmas in solar nanomaterials (EP/K022237/1) and bacterial detection (EP/K006088/1).
