Dr Jiang reckoned that a coldplasma, particularly one rich in oxygen ions (which are notoriously destructive of organic materials), would be enough to do the job of breaking up a biofilm without harming the patient.
Because hydrogen can clean the exhaust right from a cold engine start, the plasma reformer method is 20% to 50% more efficient at reducing NOx than other clean-diesel technologies, allowing less unburned fuel to pass through in the process.
