Abstract

Low-temperature atmospheric-pressure plasmas in forms of streamers and surface discharges are known to be weakly ionized and highly non-equilibrium. When powered by nanosecond pulses, the low-temperature plasma can contain energetic electrons that enable selective and energy-efficient chemistry but with mean energy of the heavy particles at or near room temperature. Such plasmas have been developed in the past decades for numerous applications including plasma-assisted ignition for combustion, pollution control, fuel reforming, plasma-aided nitration for agriculture, and plasma medicine. In addition to an introduction to the plasma sources, this talk provides two examples where transient plasmas driven by repetitive nanosecond high voltage pulses are used to achieve efficient, lean-fuel ignition for combustion and controlled oxidation-reduction chemistry for medical applications such as cancer therapy and plasmid DNA delivery.

Biography

Chunqi Jiang is a professor affiliated with both the Frank Reidy Research Center for Bioelectrics and the Department of Electrical and Computer Engineering at Old Dominion University (ODU).
