Plasmas in Liquids
While there has been work on these concepts for a number of years, it has been mainly empirical. We want bring our experience in the plasma physics and chemistry of gas-phase discharges to bear on the study and development of liquid phase discharges.
We intend to develop new approaches to the generation and application of liquid discharges. In particular we believe that additional gas injection may allow us to enhance or to change the physical and chemical environment in current systems. This could allow targeting of specific solutes and/or contaminants within water. Again based on our studies in high pressure gaseous plasmas we believe that the radical and the visible/UV light emission and the liquids electrical properties will all be very sensitive to impurities in the water which diffuse into the bubble.
We will apply the techniques we have available to the study of water discharges, looking particularly at radical, UV production and visible light emission as well as the electric properties of the plasma.
This programme was prompted by some work we have recently undertaken with a US plasma scalphel manufacturer.
