Title: Synthesis of Nanomaterials by Atmospheric Arc Plasmas

Abstract: The Micro-Propulsion and Nanotechnology Laboratory at the George Washington University is aimed to expand the understanding of plasma and nanoscale phenomena. The research is based on three plasma-related applications: (1) propulsion by micro-thrusters, (2) plasma medicine to address cell migration and cancer therapy, and (3) plasma-based nanotechnology. After a brief introduction to each line, I will focus on nanotechnology research and the application of atmospheric plasmas to synthesize nanomaterials like graphene, carbon nanotubes, and MoS2 monolayers. The plasma-healing effect of anodic arc discharges and the investigation of pulsed arcs to tailor nanoparticle growth constitute the up-to-date highlights of the research line. The next challenge is the production of advanced nanostructures with tunable electrical and optical properties using arc plasma and other environmentally friendly techniques.
