Prof. Alexander Pogrebnjak is a Professor and the Nanoelectronics Department Chair at Sumy State University, Ukraine. His scientific interests are related to nanocomposite and layered coatings, high-entropy alloys nitrides, improving of physical-mechanical and chemical properties of materials using nanosized films, modification of properties of metals and alloys by high power particle beams. Through his career Prof. Pogrebnjak was a visiting scientist at Helsinki Technology University (Helsinki, Finland), Trento University (Trento, Italy), Los-Alamos National Laboratory and Sandia National Laboratories (USA), Portugal Institute de Technology Nuclear (Porto, Portugal), Lublin University of Technology (Lublin, Poland), University of Poitiers (Poitiers, France). Prof. Pogrebnjak co-authored 12 books and over 300 per-reviewed scientific articles. Dr. Valentine Novosad is a Senior Materials Scientist at the U.S. Department of Energy’s ArgonneNational Laboratory. He completed Ph.D. studies in Physics at the Institute for Low Temperature Physics & Engineering in Kharkiv, and Laboratoire de Magnétisme Louis Néel, Grenoble, France, in 1998. During 1998–2001 he was a postdoc at the Department of Materials Science, Tohoku University, Japan. Dr. Novosad’s  areas of research interest spans from basic thin films and nanomaterials science and engineering, to microfabrication of superconducting detectors or advanced multilayers to the development of novel nanoplatforms for cancer treatment.  He is an elected Fellow of the American Physical Society, senior IEEE Member, chair of Chicago’s IEEE-Magnetics chapter and co-recipient of the UChicago Argonne Board of Governors Distinguished Performance Award & Medal. Dr. Novosad has co-authored over 200 papers, three book chapters and four patents.​
