Prof. Väino Sammelselg is a visiting professor/professor emeritus at the Institute of Physics, University of Tartu, Estonia. He completed his PhD studies in the Institute of Physics at Tartu State University and has been awarded with the Science and Technology Award of Estonian SSR and Scientific Prize of Estonia, medal of the University of Tartu, medal of IAAM, and Prize of Estonian Physical Society. He recently led the projects "Nanomaterials—studies and applications" and "Thin-film structures for nanoelectronic applications and functional coatings", both funded by the Estonian Research Council, "Services supply agreement", funded by Linde AG, and "Thin nanomaterial coating for functionalizing and protection of metal Surfaces", funded by the Archimedes Foundation. He has published 188 papers (WoS core collection) in various journals, has an h-index of 46, and serves as a member of the International Association of Advanced Materials (IAAM), as well as for research project "Carbide synthesis from recycle materials for use in manufacturing and high-tech industries". His teaching disciplines include electron microscopy/nanoscopy and physical analysis methods of solids and surfaces, and his research interests include thin-film and coating technology, surface engineering, corrosion protection, nanoparticles and 2D materials and their applications, and solid-state chemistry.
