Universidade de São Paulo (USP). Instituto de Física de São Carlos (IFSC) (Institutional affiliation from the last research proposal) Birthplace: Brazil
Holds a Bachelor's degree in Physics from the Federal University of São Carlos (1985), a Master's degree in Applied Physics from the São Carlos Institute of Physics - University of São Paulo (1988), and a Doctorate in Sciences from the Université Paris XI (Paris-Sud) (1992). Currently, he is an associate professor, MS-5, level A3, at the São Carlos Institute of Physics, University of São Paulo. He has experience in physics, with an emphasis on the structure of crystalline and amorphous solids and on the development of materials for sensing toxic gases. Regarding the study of solid structure, he has worked mainly on the following research topics: Characterization of the local and electronic structure of ceramic, vitreous, and nanostructured oxide materials using X-ray Absorption Spectroscopy (EXAFS-XANES), X-ray Diffraction, and X-ray Photoelectron Spectroscopy (XPS). Regarding the development of toxic gas sensor materials, the research has focused primarily on improving their properties, particularly selectivity and operating temperature. Current research focuses on the development of composite materials or heterostructures based on semiconductor metal oxides and graphene, applied as toxic gas sensors. (Source: Lattes Curriculum)

According to the World Health Organization (WHO), 6.7 million deaths annually can be attributed to the combined effects of ambient and household air pollution, compared to water pollution, which contributes to 1.4 million deaths. In the last decade, the remediation methods aiming to decrease gaseous pollutant concentrations in the atmosphere have only a small impact, and the degradation o…
The main goal os this proposal is to understand the effect of Pd loading on the gas-surface interaction of nanostructured SnS2. This two-year collaborative project will characterize the surface composition and electronic structure of Pd-doped SnS2 nanomaterials under operandoconditions, i.e., under different temperatures and during exposure to hydrogen. The role ofhaving or lacking adsorb…
Based on our previous experience, we propose a step forward in materials science research with the formation of a multidisciplinary Center for the Development of Functional Materials (CDFM). This center will be an offshoot of the Multidisciplinary Center for the Development of Ceramic Materials (MCDCM) which received FAPESP support from the first version of the CEPID program. The core foc…

The detection of different types of gases is becoming increasingly important in our society due to the need to identify toxic gases and organic vapors for environmental and human safety, for emission/control in the industrial sector and in medical diagnostics. Efforts by the scientific community working in this area of research are dedicated to the research of new materials capable of det…
The investigation of nanostructured transition-metal-perovskite materiais (TMPs) is attracting rapidly growing international attention owing to their unique dielectric properties and catalytic activity and consequent value in a variety of valuable applications including sensors, actuators, hydrogen production and environmental remediation. These materiais are of the general form AB03 wher…

Hydrogen (H2) is a promising gas to replace fossil fuels due to its potential as a renewable energy source with zero carbon emissions. However, H2 has safety challenges, such as high propensity to leak, being an odorless gas and highly flammable. H2 is explosive in concentrations greater than 4% by volume, which makes it essential to develop sensors that combine high response and selectiv…
The advances of industrialization and urbanization have brought an increase in environmental pollution and with it, an increase in the demand for sensors capable of detecting and monitoring the toxic gases present in the environment in real time. In addition, development of a new generation of electronics that are ultra-light, low-cost, flexible, bendable, and adaptable to the shape of ob…
Over the last decade, the growing development of new gas sensing technologies opened new paths towards faster, more precise, and reliable monitoring systems in several areas, such as industrial safety management, smart farming, food quality assessment, diagnostics, environmental monitoring, and others. The concepts of the Internet of Things and Industry 4.0 have been pointed out as a new …

Modern advances in Science and Technology have improved the quality of human life and health significantly. Nevertheless, these advances also brought several problems. Among them, the need for real-time monitoring of toxic gases is one of the biggest and most alarming problems these days. There is a requirement for simple, sensitive, selective, and stable electronic sensors for either env…

Modern advances in science and technology significantly contribute to the improvement of quality of human life, health and protection. Nevertheless, many efforts still remain to perform especially for earth protection and environmental control. Among them, the real-time monitoring of toxic gaseous pollutants, indoor as well as outdoor, with a high level of selectivity is one of the most s…
The objective of this work was to confirm or to refuse a possible relationship between the local structure (first coordination shell around the modifier cations) and the crystal nucleation mechanism in silicate glasses. The EXAFS analysis has shown that glasses that nucleate homogeneously present similar neighborhoods to their isochemical crystalline phases; whereas glasses that nucleate …
