Dr. Ioannis Anastopoulos is an associate professor at the Department of Agriculture, University of Ioannina, Arta, Greece. He has conducted postdoctoral research at the Agricultural Research Institute (Cyprus), the University of Patras (Greece), the University of Cyprus (Cyprus), and the Hellenic Mediterranean University (Greece). His research focuses on the estimation of greenhouse gas emissions from agricultural soils following the application of organic and inorganic materials, the development of adsorbent materials for wastewater treatment, and the use of organic amendments for soil remediation. He has authored more than 130 articles in peer-reviewed journals with over 12,000 citations and has been included among the Top 2% Scientists worldwide for the years 2019–24 (Stanford list, Elsevier).Prof. Lima is a Professor of the Institute of Chemistry at the Federal University of Rio Grande do Sul. Prof Lima was editor of the Journal of Hazardous Materials from 2018 to 2020. He was an editor of the Journal of Environmental Chemical Engineering (JECE) from 2013 to 2018 and Editor of Special Issues of JECE from 2018 to 2019. Now, Prof. Lima is an editor of Microporous and Mesoporous Materials. He has more than 200 published papers. He has been working on the removal of toxic compounds from aqueous effluents using various kinds of adsorbents. His research group is now broadly focused on the use of biomass, in natural and/or chemically modified forms, for the removal of toxic species from industrial effluents; the development of new adsorbent materials such as organo-functionalized silica and silicates, celluloses, and carbon nanotubes; and the production of new activated carbons derived from renewable sources. Lucas Meili is Professor in the Center of Technology at the Federal University of Alagoas, Maceió, Brazil. His areas of interest are focused in separation processes, water and wastewater treatment, and synthesis of materials, with a particular interest in adsorption and advanced oxidation processes. Dr. Dimitrios A. Giannakoudakis obtained his PhD at the City University of New York, New York City, United States (February 2017). Nowadays, he serves as an assistant professor at the University Marie Curie Sklodowska (UMCS), Lublin, Poland. His research is focused on the development of composite porous nanomaterials for (photo)(sono)(piezo)catalytic technologies for biomass valorization and (micro)plastics upcycling to green chemicals, as well as for air and water purification, linking physicochemical properties to performance and involved mechanisms. He coauthored more than 140 articles, 1 monograph, 7 edited books, and 17 book chapters with over 7000 citations. Since 2021, he has been included in the Top 2% Most Influential Scientists worldwide (Stanford list, Elsevier).
