Solar Photo-Catalysis Treatment of Synthetic Petroleum Refinery Wastewater Using Bio-Synthesized Zno Nanoparticles presenter: El Golli Asma, University of Sousse, High School of Sciences and Technology of Hammam, Sousse, Tunisia Abstract  Supercapacitors are energy storage devices that are often characterized by high power densities, fast charge/discharge cycles (sec-min) and long lifetimes (>106 cycles) which makes them very interesting components especially when they are implemented in energy management and conversion networks. The recent scientific strategy is to manufacture environmentally friendly, low-cost, and flexible devices for powering miniaturized electronic systems, as well as portable and wearable electronic devices. In this context, this work presents a carbon based solid-state symmetrical supercapacitor with electrochemical performances relatively similar to those based on commercial carbon. Indeed, Biomass-derived electrodes were implemented with a quasi-solid-state el
