Abstract

This request is aimed at the acquisition of two modern multi-user devices: a scanning electron microscope with resolutions below one nanometer (0.8 nm at 15 kV and 0.9 nm at 1 kV); and a complete scanning probe microscope. These equipment will be incorporated into the infrastructure of the Laboratory of Structural Analysis (LCE) located in the UFSCar Department of Materials Engineering, complementing and modernizing its capacity for structural analysis of all types of materials at the micrometer, nanometer and subnanometer scales. In this context, the acquisition of these equipment will contribute to the development and nanostructural characterization (by ultra-high-resolution scanning electron microscopy and scanning probe microscopy) of various systems (metals, ceramics, polymers, composites and glass), all having the common characteristic of containing nanometric phases that determine the specific properties of interest. In all cases, the greater spatial resolution that only electron microscope and probe microscopes provide, together with the chemical analysis in small regions and nanometric phases, are of enormous relevance for the characterization of such materials, as well as for identifying the processing protocols that are the most appropriate for the fabrication of nanostructured materials. The LCE fits the definition of a multi-user centralized laboratory and has done so since May of 1988, having been a pioneer in the area of electron microscopy in Brazil. (AU)
