6. EFEITO DO HG2+ E DOS ÍONS CU2+, FE2+, NI2+, SN2+ E ZN2+ NA ESTABILIDADE DE NANOPARTÍCULAS DE PRATA: UMA PRÁTICA INTERDISCIPLINAR DE NANOTECNOLOGIA EXPERIMENTAL
The growing predominance of nanoscience and nanotechnology makes it increasingly important that these topics become an integral part of all scientific education. For this reason, in the present work, an interdisciplinary experiment of nanotechnology is introduced. As silver nanoparticles (AgNPs) are the most applied nanomaterial in consumer products, the cur

7. ORBITALS IN GENERAL CHEMISTRY, PART I: THE GREAT DEBATE
In Part I of a three-part series, we present an objective survey of the technical literature discussing the inclusion of orbitals in high-school and post-secondary general chemistry. We start with the definition of orbitals. The presentation of orbitals in secondary (high) school is presented with arguments for and against. The content of orbitals in the cur

12. MODELO SEMIÓTICO DE LEITURA DE INSCRIÇÕES: APLICAÇÃO NA EDUCAÇÃO EM QUÍMICA
Inscriptions - graphs, diagrams, photographs, tables, and so forth - are central to scientific practice. In this study, a semiotic model was used to evaluate the reading of inscriptions by undergraduate chemistry students when giving oral presentations based on original research articles about environmental chemistry. Results revealed that the model helps to
