International collaboration Brazil, Portugal, Serbia, United States: Research into nanomaterials for application in electrochemical energy storage devices

Abstract

The Research Group led by Principal Researcher Prof. Dr. Emerson Sarmento Gonçalves works at the Institute of Aeronautics and Space in partnership with the Technological Institute of Aeronautics. Both serve the Brazilian Air Force, through the Department of Aerospace Science and Technology (DCTA). The main objective of his research is to obtain electroactive nanomaterials for disruptive applications in alternative energy sources and charge storage devices in aeronautical and space equipment. In this sense, taking advantage of the current paradigm disruption in the development of new space equipment, the Group proposes the development of these high-performance materials to act in devices that can operate in route correction subsystems (supercapacitors), high-density electrical storage subsystems (batteries and future hydrogen generation). These devices require developments in research to increase energy and power density as an urgent requirement.In this context, to advance the research and purposes of the Brazilian Research Group, in obtaining and applying nanomaterials such as graphene, metallic nanooxides and niobium MXenes, the visit of Researcher Prof. Dr. Biljana `ljuki Paunkovic is fundamental for her extensive experience in electrochemical and electrocatalytic reactions and the functioning of high-density devices such as fuel cells, metal-air batteries and supercapacitors.Assistant professor at the University of Lisbon (Portugal) and full professor at the University of Belgrade (Serbia), Dr `ljuki, has extensive experience in Fundamental Electrochemistry, with around 133 scientific articles, 2 books on electrocatalytic reactions associated with the operation of fuel cells and to the generation of electrolytic hydrogen and Projects recognized in the European Union.`ljuki already works in partnership with the responsible researcher, as part of his regular FAPESP Research Project (Process 2022/02737-0), and is also the co-supervisor of his supervisee. The exchange of experiences in materials and cells for energy storage will be an important means of internationalization and insertion of your expertise in this Research Group, in addition to fulfilling steps proposed in the current Project.Additionally, it is planned to strengthen international partnerships with the aforementioned Research Group and Prof. Dr. Christopher Shuck from Rutgers University (USA), who will be visiting the responsible researcher in Brazil during the same period. Professor Shuck is a specialist in chemical reactions and as a member of the research group that developed the two-dimensional material MXene (Drexel University), he will be in Brazil to give lectures and carry out experiments in relation to obtaining and characterizing niobium MXenes, also the objective of the Project of the responsible researcher.The central objective of Prof. `ljuki's visit will be to work together with the responsible professor and his students, together with Researcher Shuck, on the application of niobium MXenes, as well as graphene and metallic nanooxides, in supercapacitors and in electrolytic reactions to obtain hydrogen for high energy density devices such as fuel cells and metal-air batteries.It is planned that `ljuki will interact with the Institute's students by participating in their experiments and giving lectures on the new generation of energy storage devices and the principle of electrocatalytic reactions used to generate green hydrogen.The triangular collaboration foresees the development of new research projects relating materials and energy devices, exchange of teachers and students, participation in international events and production of scientific articles.
