Dr. Michael Arkas was born in 1970 in Athens, Greece. He studied Chemistry at the University of Ioannina (1988-92) and earned his PhD from the University of Athens, specializing in quaternary ammonium liquid crystals under the supervision of Dr. C. M. Paleos at NCSR “Demokritos”. From 1992 to 1997, he was a visiting PhD student at the “Institut de Physique et de Chimie des Matériaux de Strasbourg”, CNRS, France, for two periods. He continued his work as a project scientist on research projects funded by the European Union and rejoined the Institute of Physical Chemistry at NCSR “Demokritos” in 2007 as a special scientific staff member in the “Nanomaterials of Organized Supramolecular Structure” laboratory. Currently, he holds the position of a Senior Researcher at the Institute of Nanoscience and Nanotechnology. Dr. Arkas has extensive experience in liquid crystals, crystallography, and the functionalization and applications of dendritic polymers. His applied research interests include water purification using dendrimers and hyperbranched polymers, as well as catalytic pollutant disintegration by metal nanoparticles nucleated within dendritic cavities. He also works on composite ceramic nanospheres, hydrogels, and xerogels created via biomimetic methods. These hybrid materials, which may include active ingredients, have been successfully tested as adsorbents, antimicrobial coatings for orthopedic implants, and leathers for examination beds and other medical equipment. He is the author of 54 peer-reviewed journal publications, 6 book chapters, and holds 10 patents as a co-inventor (1595 citations, h-index: 22). He serves as a guest editor for special issues in peer-reviewed journals and reviewer for more than 50 international journals published by AIP, ACS, Springer, Elsevier, IOP, MDPI, and IEEE.
