Abstract

The objective of this proposal is to acquire a 200kV atomic-resolution transmission electron microscope for high-resolution image capture, to be employed in the characterization of various nanostructured materials, including ceramics, metals, and polymers, as well as biological material, such as yeasts, bacteria, fungi, and some proteins. In addition, the equipment will be used in order to analyze the organization and structure of materials, as well as their surfaces, at the nanometer scale. The project is coordinated by Prof. Edson Ticianelli and involves approximately 33 researchers working on four associated projects (three FAPESP Thematic Projects and one Young Researchers in Emerging Centers Program Project), with grant money of approximately R$ 1.7 million, plus another US$ 720,000. There are also 50 complementary projects linked to this request, collectively receiving funding of approximately R$ 20 million, plus US$ 3 million. The project teams work in various areas of research (chemistry, physics, biology, engineering, and materials sciences) at institutions of higher learning or research institutes, such as the USP São Carlos Institute of Chemistry, the Federal University of São Carlos Institute of Physics, the USP São Carlos School of Engineering, the São Paulo State University Institute of Chemistry, and the Brazilian Agricultural Research Corporation. In all cases, the use of transmission electron microscopy is a fundamental or even determining step in the characterization of systems and in the elucidation of behaviors, leading to explanations and proposals for practical applications.
