The Journal of advanced oxidation technologies (AOTs) has been providing an international forum that accepts papers describing basic research and practical applications of these technologies. The Journal has been publishing articles in the form of critical reviews and research papers focused on the science and engineering of AOTs for water, air and soil treatment. Due to the enormous progress in the applications of various chemical and bio-oxidation and reduction processes, the scope of the Journal is now expanded to include submission in these areas so that high quality submission from industry would also be considered for publication. Specifically, the Journal is soliciting submission in the following areas (alphabetical order): Advanced Oxidation Nanotechnologies Bio-Oxidation and Reduction Processes Catalytic Oxidation Chemical Oxidation and Reduction Processes Electrochemical Oxidation Electrohydraulic Discharge, Cavitation & Sonolysis Electron Beam & Gamma Irradiation New Photocatalytic Materials and processes Non-Thermal Plasma Ozone-based AOTs Photochemical Degradation Processes Sub- and Supercritical Water Oxidation TiO2 Photocatalytic Redox Processes UV- and Solar Light-based AOTs Water-Energy (and Food) Nexus of AOTs
