Electrolytic syntheses, characterizations, and applications of novel graphene/nanoCarbons, resulting in Superior
Electrical, Electronic, Thermal and Dielectric characteristics; also resulting in the Highest Capacities when applied to
Lead Acid and Lithium-ion Batteries, resulting from higher Utilization of Electrode Materials, 1 st to demonstrate
electrode precipitation and dissolution mechanisms in the gel-crystal electroactive zone of the lead acid battery;
synthesized graphene also resulted in higher viscoelastic mechanical behaviour in graphene-enhanced epoxy
nanocomposites prepared by in-situ reduction of GO by solvent evaporation and hot stirring. Synthesized highly
scalable and diversely applicable crystalline pristine graphene directly from graphite, with high basal planarity using
solid state processes, or alternative colloidal sonication process. Expert in Materials characterization and advanced
materials manufacturing like Friction Stir Welding, where I am the 1 st to demonstrate with clear images, the materials
flow and damage tolerance in Aluminum FSWs.
