Affiliation: Electronic Materials Research Department, Advanced Technology and New Materials Research Institute (ATNMRI), City of Scientific Research and Technological Applications (SRTA-City), New Borg Al-Arab City, Alexandria 21934, Egypt ORCID: https://orcid.org/0000-0001-8308-9888 Email: [email protected] Abu Bakr Nassr received his B.Sc. and M.Sc. degrees in Chemistry from Al-Azhar University, Egypt and the Ph.D. degree in Industrial Chemistry on the topic of development of electrocatalysts for electrooxidation of organic molecules for fuel cells applications from Institute of Chemistry, Faculty of Natural Science II, Martin-Luther University Halle-Wittenberg, Germany. After postdoctoral studies at the same university he was working as a Research Fellow at the electrochemistry group at Chemistry Department, Southampton University, UK. He also worked as research project leader at Fraunhofer Institute for Microstructure of Materials and Systems (IMWS), Germany, working on different projects related to water electrolysis and corrosion evaluation of bipolar plates for water electrolysis technology. Currently, He is working as a Research Associate Professor of electrochemistry and materials chemistry at the Institute of advanced technology and new materials, SRTA-City, Egypt , where he lead a team of researchers for developing nanomaterials for electrochemical applications with focusing on electrocatalysts and electrode materials development for different electrochemical systems such as fuel cells, battery, supercapacitors, electrolyzers and bioelectrochemical systems. He is a reviewer of many journals in catalysis and electrochemistry fields such as Journal of applied electrochemistry, Journal of power sources, Ionics, international journal of hydrogen energy, materials science for energy technologies, International journal of energy research, energy conversion and management etc. He has published over 20 relevant papers in areas such as electrocaylsis for fuel cells, water electrolysis, development of carbon materials electrodes for supercapacitors, and electrocatalysts for metal air batteries applications, etc.
