Seyedmehdi Sharifian received his Ph.D. in Chemical Engineering at the Vienna University of Technology, then worked as a postdoctoral fellow at the University of Tehran. Since 2018, he started to work as an assistant professor at the same university. He is the head of the research laboratory of sustainable and green chemical processes. Every year many graduate and undergraduate students actively work at his research lab and achieve their study/research on chemical engineering. His research interest is generally in separation techniques in chemical processes. One of the most important of his research focuses is wastewater treatment systems by adsorption and oxidation processes. In addition to the authorship of many scientific papers, he is the reviewer of many relevant journals, mainly in wastewater treatment, water quality, oxidation process, biowaste to value-added product subjects. Neda Asasian-Kolur received her Ph.D. in Chemical Engineering from the Amirkabir University of Technology in 2013. Since 2017, she has worked as an assistant professor at the University of Tehran. She is the head of the adsorption research laboratory at the University of Tehran, and every year many graduates complete their studies under her supervision. To date, she has authored many peer-reviewed publications on environment-related topics. Her research interests include wastewater treatment, adsorption processes, preparation, surface functionalization, and characterization of adsorbents/catalysts for environmental purposes. She is the reviewer of many well-known journals in environmental chemistry research fields. Mika Sillanpaa is a Professor affiliated to the Department of Biological and Chemical Engineering at Aarhus University, as well as King Saud University, Saudi Arabia. He received his M.Sc. (Eng.) and D.Sc. (Eng.) from Aalto University, Finland. Prof. Sillanpaa's publications have been cited over 44,000 times (Google Scholar), and he has received numerous awards for research and innovation. Among these, he is the first Laureate of the Scientific Committee on the Problems of the Environment (SCOPE)'s Young Investigator Award. From 2017 to 2020, he has been listed as a Highly Cited Researcher by Thomson Reuters. In 2018, he was invited to become a Member of the Finnish Academy of Sciences and Letters and the Academy of Technical Sciences.
