ABOUT/BIOGRAPHY

Dr Vassilis Psycharis (b. 1959) is Director of Research at the Institute of Nanoscience and Nanotechnology (INN) at NCSR “Demokritosˮ and Head of the Crystallography and Coordination Chemistry of Materials Group since 2010. He was appointed Assistant Director of the Institute of Materials Science (IMS) during the period of 2009-2010. He was Supervisor of the Post-Graduate Student Program of INN and Member of the Graduate Student Program Supervisor Committee of NCSR “Demokritos” for a period of 14 years (2000-2014). His scientific interests and research activities cover almost all areas of research in X-ray crystallography, i.e. single crystal studies by X-ray diffraction methods; crystal structure analysis by the Rietveld Method using X-ray powder diffraction patterns; crystal structure/property correlation; crystal engineering; study of intermolecular interactions with Hirshfeld Surface analysis methods; organic superconductors; HTc superconducting ceramic materials; hard magnetic materials and molecular magnets; thin film and small particles studies by X-ray diffraction techniques, with XRR and SAXS methods; instrumentation for powder diffraction applications. He also uses occasionally large facilities, such as Neutron and Synchrotron, for structural studies. He has published 351 papers in international peer-reviewed Journals, 4 in peer-reviewed Congress Proceedings, and more than 100 presentations in conferences (14 oral presentations). He has more than 6000 hetero-citations and an h index of 43. He has been involved as coordinator or main researcher in 10 national projects with total funding for NCSR “Demokritos” group of approximately 1 M €uro since his employment at INN (July 1995). He is also a co-author in a chapter entitled "Magnetic Phenomena in Zero-Dimensional Transition-Metal Spin-Clusters" in the book "Magnetism and Superconductivity in Low-Dimensional Systems: Utilization in Future Applications" Nova Science Publishers NY, Ed. D.Stamopoulos, 2008, pp.1-78.  He has contributed after invitation the chapter: “Twining: Crystallography” in the Reference Module in Materials Science and Materials Engineering_2016 (DOI: 10.1016/B978-0-12-803581-8.03209-4). Also is a coauthor in two chapters in the book “Single‐Molecule Magnets: Molecular Architectures and Building Blocks for Spintronics” Editor: Małgorzata Hołyńska (DOI:10.1002/9783527809929), 2019 Wiley‐VCH Verlag GmbH & Co. KGaA. He was appointed as co-Guest Editor in the Special Issue of Polyhedron (Vol. 28(15), 2009) entitled "The Impact of Crystallography on Inorganic Chemistry in Greece".  He is also appointed as Guest Editor in the Special Issue of Inorganics, 2020, entitled “Advanced X-Ray Crystallographic Structural Studies in Inorganic Chemistry”.  He was a member of the organizing committee and the main tutor of the 2nd School of the Hellenic Crystallographic Association with subject on Rietveld method, organized with the support of the International Union of Crystallography in 13-14 October 2004 at Athens University.  Member of the organizing committee of the international workshops on "Current trends in nanoscopic and mesoscopic magnetism" at Santorini, September 2006; Delphi, September 2008; Chalkidiki,, June 2012; Pylos, October 2016, Rodes 2019 and 8th NAGC Sparta, 2018 all organized in Greece. Member of the organizing committee of the 3rd Congress of the Hellenic Crystallographic Association, 22-24 September 2006, Patras, Greece and of the 10th  Congress of the Hellenic Crystallographic Association, 15-17 October 2021, Athens, Greece. Member of the organizing committee of the 1st Panhellenic Workshop on Inorganic Chemistry, 19-21 Novemebr 2021, Patras, Greece.
