Moisés Romolos Cesario is currently Guest Professor at the Federal University of Paraiba (Brazil). He obtained a PhD in physical chemistry from a Joint PhD program between the University of Strasbourg (UNISTRA), France, and the Federal University of Rio Grande do Norte (UFRN), Brazil. His scientific expertise encompasses synthesis methods (Pechini, microwave assisted self-combustion, hydrothermal, solid-state reaction), ceramic materials processing, catalytic processes (steam and dry methane reforming), electrocatalysis. His technical expertise encompasses gas chromatography – mass spectroscopy (GC-MS), electrochemical impedance spectroscopy (EIS), thermogravimetric analysis (TGA). X-ray diffraction (XRD), X-ray photoelectron spectrometry, Fourier transform infrared spectroscopy (FTIR), scanning and transmission electron microscopy (SEM, TEM), temperature-programmed desorption, reduction and oxidation (TPD, TPR, TPO), and N2 physisorption. He is the author of two books – M.R. Cesário, D.A. Macedo, C. Gennequin, and E. Abi-Aad, Catalytic Materials for Hydrogen Production and Electrooxidation Reactions (2018), and M.R. Cesário and D.A. Macedo, Frontiers in Ceramic Science: Functional Materials for Solid Oxide Fuel Cells: Processing, Microstructure and Performance (2017). He wrote 5 book chapters and holds 1 patent. Prof. Daniel Macedo has devoted the last decade of his academic career to the study and improvement of ceramic and composite, catalytic materials for energy conversion in electrochemical devices. He is author of several scientific papers published in conferences and journals of international circulation, book chapters, and patents. He is an adjunct professor at the Department of Materials Engineering of the Federal University of Paraíba (Brazil).
