Abstract

This proposal for the acquisition of EMU-PMP is associated with three APR projects: "Printed Electronic Devices for Sustainable Electronics," coordinated by Professor Neri Alves; "Mimetic Models of Membrane Applied in Studies of Interaction, Detection, and Removal of Emerging Pollutants," coordinated by Professor Priscila Aléssio; and "Fission Track, U-Pb, and U-Th/He Methods in Apatite and Zircon Minerals: Thermochronology of the Northern Part of the Paraná Basin and the Brasília and Ribeira Ranges," coordinated by Professor Carlos Alberto Tello Sáenz. All these projects have in common the processing and/or characterization of materials on a nanoscale for various applications (nanotechnology) and/or to obtain fundamental information (nanoscience). However, the acquisition of EMUs-PMP will benefit researchers beyond those composing the team of this proposal, driving research in the field of Nanoscience and Nanotechnology (N&N), an area in which our team has been active for years. Hence, the title "Exploring Frontiers in Nanomaterials" reflects the intention to expand knowledge in this area, working at the frontier of this knowledge. To achieve this, however, equipment is needed to access structures on a nanoscale, enabling the processing, characterization, and application of such nanostructures. N&N involves manipulating materials between 1 and 100 nanometers, and the interest in this area arises because, at this scale, materials exhibit distinct physical and chemical properties from their macroscopic forms ("bulk"). In this context, the supramolecular arrangement in thin films (nanometers in thickness), for example, strongly influences the optical and electrical properties of these films and, consequently, the performance of devices based on them. The same applies to the morphology (size and shape) of nanostructures in colloidal dispersions. These two aspects - controlled growth of thin films on a nanoscale & characterization of these films and nanostructures in colloidal dispersions - form the basis of this proposal. Therefore, the proposal requests four instruments to complement the research infrastructure in N&N available in the Physics Department of FCT/UNESP: i) thin film deposition system, ii) atomic force microscope (AFM), iii) impedance analyzer, iv) infrared absorption-reflection spectrometer with polarization modulation (PM-IRRAS).
