Dr. N. Dimakis specializes in computational materials science, with research dedicated to the development of innovative materials that enhance fuel cell efficiency and facilitate the creation of graphene-based pseudocapacitors and supercapacitors. His work encompasses the study of adsorption and co-adsorption behaviors of CO, water, and triflate ions on platinum-based alloys, simulating the anode catalyst in methanol and hydrogen fuel cells. Additionally, Dr. Dimakis studies ionomer membrane spectra characterization for Nafion, SPEEK, and Aquivion membranes, crucial components as polymer electrolytes in fuel cells. His research also explores the interactions of manganese, cobalt, and vanadium oxides with graphene and graphene oxides in hydrated environments, aiming to

advance the applications of these materials in energy storage and conversion technologies.

As the Deputy Director, Dr. Dimakis will collaborate with the Head of the Natural Sciences Unit (Dr. Haiduke Sarafian, Professor of Physics and Endowed Chair of John T. and Paige S. Smith Professor of Science, Pennsylvania State University, USA) and the Director of the Sciences Division (Dr. Ampalavanar Nanthakumar, Professor, State University of New York , Oswego, USA.) in the organization of all the conferences (small symposiums) organized by the Division and the Unit. He will also serve as associate editor of the Athens Journal of Sciences.

Dr. Dimakis has published extensively in this field, including notable works such as:
