Prof. Vincenzo Vaiano is Associate Professor of Industrial Chemistry at Department of Industrial Engineering of University of Salerno. In March 2006 he received the title of Doctor of Philosophy (PhD) in Chemical Engineering (Thesis: "Heterogeneous Photocatalytic Selective Oxidation of Cyclohexane"). In 2005, he conducted research activities at the University of Bradford (UK) under the supervision of prof. Roger I. Bickley (pioneer in the field of heterogeneous photocatalysis and author of several scientific papers dealing on heterogeneous photocatalysts). prof. Vaiano is member of the editorial board of "Journal of Advanced Chemical Engineering" (ISSN: 2090-4568), "Journal of Advanced Engineering" (ISSN 2576-8506), "Catalysts" (ISSN 2073-4344), “Nanomaterials” (ISSN: 2079-4991) and “Frontiers in Environmental Chemistry (Electronic ISSN: 2673-4486)”. He published more than 190 papers on International Journals (h-index 39 from SCOPUS). He is a reviewer for several international scientific journals such as: Catalysis Today, Chemical Engineering Journal, Applied Catalysis A, Applied Catalysis B, Chemosphere, Chemical Engineering Science, Solid State and Material Science, Industrial and Engineering Chemistry Research, International Journal of Hydrogen Energy and Water Research.

Prof. Dirk Poelman studied physics and obtained his Ph.D. on rare earth doped sulfide electroluminescent thin films at Ghent University (Belgium). Since 2001, he has a permanent appointment at Ghent University, where he is leading the research group Lumilab. He is a full professor since 2012. Dirk Poelman has experience in different fields of solid state physics research, including thin film deposition and optical characterization, photo-, electro- and cathodoluminescent and photochromic materials, structural and electrical defects in semiconductors, photocatalysis for air purification, x-ray analytical techniques and human vision. His current research is focused on inorganic phosphors for white LEDs and displays and persistent luminescent materials for safety illumination and medical imaging. He has (co)organized numerous conferences, such as EL2002 (Int. Conf. on Electroluminescence), ICTF14 (Int. Conf. on Thin Films) and "Phosphoros", the first international conference on persistent luminescence in 2011, and has chaired the ICOOPMA conference in Ghent in 2022. Dirk Poelman is member (and former president) of the Belgian National Committee for Crystallography and holds several administrative functions at the university. He has been editor of the Journal of Luminescence and is academic editor of the MDPI journals Materials, Photochem and Radiation.
