Ministério da Ciência, Tecnologia e Inovação (Brasil). Centro Nacional de Pesquisa em Energia e Materiais (CNPEM) (Institutional affiliation from the last research proposal) Birthplace: Brazil
Bachelor of Physics from the Federal University of Paraná (1981-1984), Master of Physics from the University of São Paulo - São Carlos campus (1985-1986) and PhD in Solid State Physics (Physique des Solides) from the Université Paris-Sud Campus Orsay, France (1986-1990). Postdoctoral internship at the Laboratoire Louis Néel, CNRS, Grenoble, France, in 1995. Currently, he is a researcher at the National Synchrotron Light Laboratory (LNLS) of the National Center for Research in Energy and Materials (CNPEM), Campinas, where he heads the Heterogeneous and Hierarchical Matter Division and the project of some beamlines within the new synchrotron light source, SIRIUS, of LNLS. He is also a researcher, on detachment, at the Centre National de la Recherche Scientifique - CNRS, France. He works, or has worked, in the areas of condensed matter physics, scientific instrumentation, and several areas in materials science, mainly in the following themes: synthesis, natural and enviromental materials, photovoltaic materials, X-ray spectroscopy, X-ray diffraction and X-ray microscopy with synchrotron light.

The project is the joint effort of an Italian team of researchers belonging to CNR-IC in close collaboration with the IIT, and a Brazilian team working at the novel LNLS synchrotron radiation source (SIRIUS). It aims to study chemical and structural transformations of novel Pb-free perovskites nanomaterials. Lead-based perovskites are currently the gold standard of perovskites for photovo…

Diamonds are the hardest mineral on the planet. They are refractory and resistant minerals; therefore they are considered time capsules that may preserve other deep mantle minerals, melt and fluid inclusions that were trapped in their crystal structure during crystallization. Most diamonds are formed in the lithosphere at depths of about 130-150 km in the Earth's interior. On the other ha…
The development of sustainable energy sources, in special solar energy, is crucial to humanity and mitigation of global warming. In this context, Perovskite Solar Cells (PSCs) have received significant attention due to the high efficiency achieved in a few years and the low preparation cost. Despite this, the stability of the PSCs remains the most critical issue to be solved, although sig…
This master's project aims to implement the ptychography technique, which consists of imaging with coherent X-rays - without the use of lenses after the sample - by phase recovery. X-ray imaging, under development in modern, state-of-the-art synchrotron light sources, has been able to achieve a resolution of the order of tens of nanometers in a variety of objects of study. A methodologica…
The effects of global warming have evidenced the need for development and improvement of environmentally friendly energy sources such as solar cells. In this context, perovskite solar cells (PSCs) have received attention mainly due to their high-power conversion efficiency close to silicon solar cells (25.7 vs 26.1%), low cost of preparation, and versatile properties. To obtain highly eff…
The coherent X-ray imaging technique development by phase retrieval is very recent. This technique has been demonstrated to achieve nanometric resolution in the last years. In general, for all coherence-based imaging techniques the experimental approach is not simple and demands a lot of effort in experimental procedure, instrumentation, and data analysis, which, in many cases, has not be…
