Prof. Dr. Leandro Martín Socolovsky (English version)

(Universidad Tecnológica Nacional – Facultad Regional Santa Cruz / CONICET)

Topic : About mass-production of graphene and on the applications in nanoheterostructures.

In our laboratory we have produced graphenes by means of two techniques, mechanical grinding and chemical synthesis. We will show the results we obtained through mechanical grinding from the use of two ball mills, one of them of national design and manufacture; and we will comment on the scalability of production using this technique. With chemical synthesis we managed to produce nanoheterostructures based on graphene sheets, to which we have attached nanoparticles in order to obtain additional functionalities. We will talk about the possibilities of using one of these Fe3O4 @ rGO nanoheterostructures in various fields of application.

Summary Background

Dr. Socolovsky is an Independent Researcher at CONICET and a professor at the UTN FRSC. He is Experimental Physicist. He has been working with nanostructured magnetic materials for 25 years. He has published more than 60 articles in specialized journals. He has written 3 book chapters. He has presented works in more than 160 congresses, mostly in the area of magnetic properties, magnetotransport and structural nanostructured materials. His training was carried out in the Department of Physics (FCE – UNLP), where he attended the degree in Physics and the doctorate in Sciences; and in the Faculty of Engineering of the University of Kyoto (Japan), as a research fellow. He completed two post-doctorates in Brazil, one at the “Gleb Wataghin” Physics Institute (UNICAMP, Campinas); and the other at the Institute of Physics of the Federal University of Goiás (UFG, Goiânia). Advices or has advised or co-advised 3 students for degree in Engineering; 1 Master thesis in Physics; and 6 PhD in Engineering. He advised postdoctoral fellows in Engineering. He has been a master’s and doctoral thesis jury, and graduation theses at UBA, UNLP, UNSAM and Balseiro Institute, as well as at USP and UCS (Brazil). He has been sworn in entries and evaluation of technical personnel and researchers of CONICET; and of projects for various scientific agencies of Argentina, Brazil and Colombia. He was professor at the Faculty of Engineering of the University of Buenos Aires, Faculties of Engineering and Exact of the National University of La Plata, at the University of Quilmes, the Faculty of Exact Sciences (National University of the Center of the Province of Buenos Aires), and at the Institute of Physics “Gleb Wataghin” (UNICAMP, Brazil). Taught postgraduate courses on electron microscopy at the UTN-FRSC, FI-UBA and the UFG (Brazil), magnetic supernanoparticles and their properties in the USP (Brazil) and the CICATA (UPN-Mexico); and about experimental methods in nanotechnology (UNQui). Had conferences on nanomagnetism at the FI-UBA, UNPA, UPN (Spain), the USP and the UFABC (Brazil); and in professional events in Peru and Colombia. Performs outreach activities in the “Nano por un día” (FAN) program. He has written research articles aimed at engineers. He has been a contributor to the exhibition “Nanoaventura”, of the Science Museum of the State University of Campinas (UNICAMP, Brazil). Collaborate in science fairs as an evaluator and consultant. He has written freelance newspaper articles and has worked as a teacher trainer and then trainer coordinator at AXED S.A. (Buenos Aires), and as an external trainer for Degem Systems, Ltd. (Israel) in Puerto Rico. He is Secretary of Science, Technology and Postgraduate of the Santa Cruz Regional Faculty of the UTN. He was co-organizer and deputy director of the Institute of Technologies and Engineering Sciences “Hilario Fernández Long” (INTECIN), which depends on the UBA and CONICET, between 2010 and 2015. He is a member of the Advisory Board of the Argentine Nanotechnology Foundation. Advise on the application of nanostructured materials for technological applications, particularly in environmental engineering. Has extensive experience in structural characterization techniques such as X-ray Diffractometry (XRD), Scanning and Transmission Electron Microscopy (SEM, TEM, HR- TEM), Low Angle X-Ray Dispersion (SAXS) and X Ray Absorption (EXAFS-XANES); magnetic measurements (VSM and SQUID), and electric transport and magnetotransport (Magnetoresistance and Hall effect). He also works with normal and thermal scanning Mössbauer spectroscopy. He is a regular user of the facilities of the National Laboratory of Light Synchronous (LNLS, Campinas, Brazil), where he has coordinated and carried out more than 30 projects. He is an advanced user of the Microscopy Laboratory of the aforementioned institution. Work with materials preparation techniques by mechanical alloying.
