Influence of Pre-Mechanical Exfoliation on the Synthesis of Reduced Graphene Oxide via the Hummers Method
(Instituto de Tecnologia e Educação Galileo da Amazônia, 2025) VALADÃO, Suelem Cabral; LEITE, Jandecy Cabral
This study investigates the effects of pre-mechanical exfoliation on the synthesis of reduced graphene oxide (rGO) via the Hummers method, employing a hybrid approach combining thermal and mechanical treatments. Initially, graphite was subjected to thermal expansion at 900 °C for 15 minutes, followed by ball milling in the presence of sulfuric acid for 12, 24, and 48 hours. The samples were oxidized using the Hummers method and chemically reduced with ascorbic acid. Characterization was carried out using X-ray diffraction (XRD), Raman spectroscopy, and scanning electron microscopy (SEM). Results demonstrated that the combination of treatments significantly influences the structural and morphological properties of rGO, enhancing exfoliation efficiency and improving the quality of the final material. This hybrid approach is a promising strategy for scalable production of graphene-based materials.

Análise de Viabilidade Econômico-Financeira e de Maturidade para Implementação de Conceitos Indústria 4.0
(Instituto de Tecnologia e Educação Galileo da Amazônia, 2025) TAHER, Thyago Mileo; NASCIMENTO, Manoel Henrique Reis
The adoption of Industry 4.0 technologies and concepts has proven to be an effective strategy for increasing the competitiveness of industrial companies. However, many organizations face challenges in assessing both the economic-financial feasibility and the organizational maturity level required for adopting these technologies in an integrated and simplified manner. This dissertation proposes a model that combines Return on Investment (ROI) analysis with the TOE (Technology, Organization, and Environment) framework, providing a holistic view of the feasibility of transitioning to Industry 4.0. The model was applied to an electronics manufacturing company in the Manaus Industrial Hub, which had already started its technological migration but without using structured evaluation methods. Results showed highly positive financial returns and adequate organizational maturity, confirming the feasibility of implementation. The developed model is concluded to be simple, efficient, and applicable on a large scale, providing industries with a solid foundation for decision-making in digital transformation.
Análise dos Desafios na Transição para Indústria 4.0: Um Estudo sobre a Integração de Sistemas de Custeio em Ambientes Automatizados
(Instituto de Tecnologia e Educação Galileo da Amazônia, 2025) SILVA, Maeli Oliveira da; MARINELLI FILHO, Nelson
This study analyses the challenges faced during the transition from traditional costing systems to absorption costing systems in the context of Industry 4.0. By applying heat maps to industrial costing spreadsheets of electronic components, inconsistencies were identified that reflect broader structural barriers of industrial digital transformation. The methodology relied on data visualization techniques to detect null and zero values at different stages of the migration process. The results revealed seven critical categories of inconsistencies: interoperability issues, complexity in indirect cost allocation, implementation and maintenance costs, workforce training, real-time data management, compliance and security, and adaptation to Industry 4.0 dynamics. It was concluded that such inconsistencies represent significant barriers to transition, especially in highly automated industries. The study also proposes a framework for assessment and mitigation, contributing to the literature on digital transformation in the Brazilian industrial context.
