Mohammed Essaid Achour received "Thèse de 3ème cycle" from the Bordeaux University, France, and “Thèse d’état” from the Moulay Ismail University of Meknes, Morocco, degrees in field of Physics in 1983 and 1991, respectively. From 1983 to 1992 he was “Maitre assistant” at Sciences Faculty of Meknes, Morocco, “Maitre de Conférence” (1992-1996) and Professor. He joined the Sciences Faculty at Kenitra in 1999. From 1997 to 2011 he was also teacher at the Royal Military Academy at Meknes. His research interests include electromagnetic and electrical properties, microwave characterization and dielectric responses of the composite materials including carbon dots, graphene, carbon nanotubes, carbon black, and natural fibers in the natural or synthetic polymers. He has co-authored more than 90 peer-reviewed scientific papers published in leading refereed journals, 13 book chapters and 6 guest editorials. He was founder and Chair of several editions of the International Symposium on Dielectric Materials and Applications (ISyDMA) and the Moroccan Spring School on Advanced Materials (MoSSAM), and Chair of the Fourth International Meeting on Dielectric Materials (IMDM’4; Marrakech, Morocco, May 2013). 

Cyril Popov received his MSc in Chemical Engineering in 1990 and PhD in 1994 from the University of Chemical Technology and Metallurgy, Sofia, Bulgaria. In the period 1995-1997 he was a Postdoctoral Fellow at the National Institute of Advanced Industrial Science and Technology (AIST), Tsukuba, Japan and at the Central Laboratory of Photoprocesses, Bulgarian Academy of Sciences, Sofia, working on preparation and investigation of novel materials in the ternary system B-C-N. In 1998 he joined the Institute of Nanostructure Technologies and Analytics (INA), University of Kassel, Germany, where at the present he is a Group leader. His current research interests cover deposition, characterization, nanostructuring and applications of nano- and ultrananocrystalline diamond films and monocrystalline diamond. He is co-author of more than 120 publications, 25 contributions to conference proceedings and 18 book chapters, co-editor of 5 books.
