Abstract

The project aims to incorporate a specialized holder for in-situ analyses, allowing precise control of temperature and electrical potential. The holder will be obtained with a permanent license for the AXON Synchronicity software, which provides motion correction for thermal effects, enabling stable analyses at nanoscales. Additionally, the project includes the acquisition of an 80mm Energy Dispersive X-ray Detector (EDS) based on Silicon Drift Detector (SDD) technology. This detector, Oxford AZtecEnergy, will enable ultra-fast composition mapping within minutes, significantly improving the operational efficiency of the microscope and the quality of chemical analyses. The synergy between the upgrade of the 80mm EDS Detector and the acquisition of the in-situ holder will significantly enhance the analytical capabilities of LCE, enabling unprecedented analyses in Latin America and strengthening its position as a reference center for material structural characterization in the country. The 3-year project is supported by various associated projects involving renowned researchers, reinforcing the importance and relevance of the investment for the advancement of nanoscale research. The proposal highlights the uniqueness of the Protochips Fusion AX system, which provides in-situ analyses with precise control, including high temperatures and application of electrical potential, a system unprecedented in Latin America. Founded in 1976, LCE is a multidisciplinary laboratory serving researchers from various institutions. With a robust infrastructure and a history of contributions to science, the laboratory aims to remain at the forefront of electron microscopy research, ensuring flexible and efficient access to its equipment. The proposal emphasizes the importance of the investment to meet the growing demands of users and promote significant advances in structural material characterization. (AU)
