**About the Special Issue Editor**

**Bogdan Stefan Vasile** received his M.S. degree in composite materials in 2008 and his Ph.D. in chemical engineering in 2011 from the University Politehnica of Bucharest, Romania. His Ph.D. research activities have focused on the synthesis and characterization of zirconia and alumina nanopowders and nanocomposites. Since 2018, he has been a researcher at University Politehnica in Bucharest, Faculty of Applied Chemistry and Materials Science, National Research Center for Micro and Nanomaterials. His current research interests involve the unconventional chemical synthesis, characterization, and multipurpose applications of advanced micro and nanomaterials. His main specialization is in the field of transmission electron microscopy (TEM), scanning transmission electron microscopy (STEM), energy dispersive X-Ray analysis (EDX), energy filtered transmission electron microscopy (EFTEM), and energy electron loss spectroscopy (EELS). His specializations in the field of microscopy and nanomaterials were achieved with the FEI Application Laboratory, Anadolu University and the Institute for Electron Microscopy of Graz University of Technology. His overall research activities have allowed him to publish over 165 ISI papers with an h-index of 27. His passion for microscopy led to the foundation of the Electron Microscopy Society in Romania as one of the founding members; he was also the first President. From 2008, he has been the Leader of the Structural Analysis and Electron Microscopy laboratory at UPB and Technical Director at both the National Research Center for Food Safety (CNpSA) and the National Research Center for Micro and Nanomaterials (CNMN).
