- 1. Synthesis of delafossite CuCrO2 via solution combustion method and its acid functionalization for biodiesel productionAbstract CuCrO2 was synthesized by solution combustion synthesis (SCS) and applied as a heterogeneous catalyst to produce soybean biodiesel. The combustion reaction was carried out using urea as a fuel, and copper (II) and chromium (III) nitrates as precursors. After the powders’ obtention, these were calcined and functionalized in an acidic medium. The po Cerâmica.Publicado em: 2023

- 8. Universal Approximators: New Approach for the Curve Fit of the COVID-19 Infected PopulationABSTRACT Fuzzy systems that include Takagi-Sugeno inference method with linear outputs, are widely known to have the ability to uniformly approximate any polynomial with high precision and, as a consequence, any continuous function, by applying the approximation theorem of Weierstrass. There is one more advantage for these methods which is to obtain an expli Trends in Computational and Applied Mathematics.Publicado em: 2022
