Artigo de Evento Prototipagem por meio da impressão 3D e o seu impacto como alternativa para redução de custos na indústria 4.0(2025-01-28) Costa, Gabriel Vitor Maia da; Oliveira Neto, Benjamin Batista deThe 3D printer prototyping method is not considered a recent technology, but it has made a huge technological leap due to the development of new materials. As a result of industry 4.0 focusing on intelligent production, rapid prototyping enters this context, as it is a means capable of revolutionizing production processes. Bearing in mind the growing importance of this technology as a part production process and considering the need to have greater discernment and a guide on possible applications in companies, this present article, based on a literary review, aims to present the impact of the use of printers 3D in industries 4.0, based on possible cost reduction and its impact on sustainability. Additionally, the conclusive results serve as a basis to help direct research initiatives to implement the use of this technology.Artigo de Evento Estudo da influência do lítio na síntese de titanato de sódio como uma alternativa para baterias de estado sólido(2025-01-04) Souza, Handerson Cunha de; Moura, David da Silva; Oliveira Neto, Benjamin Batista deThe growing demand for new energy sources has been a stimulus for extensive research in the area of materials, especially in high-performance solid-state batteries. Recently, sodium trititanate (Na2Ti3O7), an inorganic chemical compound, has received attention due to its effectiveness in ion exchange and catalytic properties. However, its application as an electrolyte in solid-state batteries is limited due to its low electrical conductivity. To overcome this limitation, lithium-doped Na2Ti3O7 nanoparticles were synthesized in different proportions, ranging from 0% to 5% by mass, using the microwave-assisted hydrothermal method. Samples were extensively characterized by XRD, 0%, 1% and 5% samples were also analyzed by DTA, Raman spectroscopy and complex impedance spectroscopy. Notably, the 5% lithium doped sample exhibited an electrical resistance approximately one order of magnitude lower than the undoped material. These promising results highlight the potential of doped sodium titanate as a viable component for high-performance solidstate batteries due to its enhanced structural and conductive properties.
