Carlos Eduardo Maduro de Campos
He holds a Bachelor’s Degree (1999) and a Master’s Degree in Physics (2001) from the Federal University of São Carlos. He holds a Ph.D. in Physics from the Federal University of Santa Catarina (2005), having completed part of his doctoral period at the Université Pierre et Marie Curie – Paris VI, in France (2003-2004). He is currently an Associate Professor IV in the Department of Physics at the Federal University of Santa Catarina, user of the Brazilian Synchrotron Light Laboratory (LNLS) since 2002, and a reviewer for more than 20 scientific journals in various areas. He has experience in the area of Condensed Matter Physics, with emphasis on Structure, Vibrational, Thermal, and Optical Properties of Nanocrystalline Solids, acting mainly on the following topics: mechanochemical synthesis (MQ, mechanochemistry), powder X-ray diffraction (XRPD), calorimetry (DSC), X-ray absorption (XAS: XANES and EXAFS), Raman scattering, semiconductors (III-V, III-VI, and II-VI) and chalcogenide intermetallic alloys (using elements from group VI of the periodic table). Over the past 16 years, he has been developing studies on the variations in physical properties and phase transitions of semiconductors, superconducting and intermetallic alloys produced by MQ as a function of pressure using diamond anvil cells (DAC) using X-ray absorption techniques ( XAS), Raman spectroscopy and X-ray diffraction (XRPD) in the XDS beamline of the LNLS. He has applied knowledge about XRPD and the Rietveld Method to determine phase fractions, crystallite size distribution (of varying shapes), and microdeformation in inorganic materials synthesized by MQ, chemical, and conventional metallurgy routes. Over the past 9 years, he has dedicated much of his research activities to the identification, quantification, and phase transitions of organic materials (drugs and liquid crystals) using XRPD, DSC and Raman, with a system capable of carrying out simultaneous DSC-Raman experiments. The most important innovation of the projects developed in collaboration with researchers from the Pharmacy Department of UFSC is the use of mechanochemistry to produce solid dispersions that show improvements of up to 318% in solubility and up to 4 times in the dissolution rate of the studied drugs. Among the most recent scientific interests, we highlight: i) the determination of molecular crystal structures (with biological and technological applications) from XRPD data obtained using conventional and synchrotron light sources, ii) Obtaining theoretical vibrational spectra (Raman and Infrared) through calculations of electronic structure using computational methods, and iii) Microstructural characterization of nanomaterials using Total Scattering and Analysis of the Debye function; iv) Built electrochemical sensors with the inorganic nanocrystals synthesized by MQ. These lines of research complement each other, allowing for a refined characterization of the materials studied and greatly expanding the horizon of multidisciplinary partnerships.
