1. Synthesis and Molecular Modeling Study of Two Bromo-Dimethoxybenzaldehydes
This work describes the synthesis, molecular structure, and packaging of the compounds 6-bromo-2,3-dimethoxybenzaldehyde (6-BRB) and 5-bromo-2,3-dimethoxybenzaldehyde (5 BRB). Characterization in the solid-state was carried out by X-ray diffraction, and the analysis of the interactions was described by the Hirshfeld surface, which helps in understanding the

3. An Alternative Description for the Electronegativity Difference in Binary Ionic Solids
We are introducing an alternative analytical expression to the electronegativity difference (∆χ) as a function of the charge ge, g is the charge factor, the fraction of the electronic charge devoted to the bond and e the elementary charge, the packing factor (p) and the effective atomic number (Zeff) of binary ionic solids, by using the very basic Coulomb

6. Abordando a Relação Clínica e a Comunicação de Notícias Difíceis com o Auxílio das Artes e dos Relatos Vivos
RESUMO Introdução A Relação Clínica (RC) é um termo mais abrangente do que relação médico-paciente e, atualmente, tem sido utilizado para descrever o contato da equipe de saúde com o paciente e seus familiares, além da interação da equipe entre si. Para estabelecer relações interpessoais satisfatórias, é importante reunir habilidades de co

8. AUTORIA COLETIVA EM AMBIENTE INFORMATIZADO NO ENSINO SUPERIOR DE QUÍMICA
Collective authorship or a text written by more than one person in a computer-based environment can bring significant benefits to chemistry teaching, mainly concerning flexibilizing forms of interaction among those involved and collaborative construction of knowledge. This work investigates collective authorship activities based on constructing argumentative

9. DFT Study of the Interaction between the Ni2+ and Zn2+ Metal Cations and the 1,2-Dithiolene Ligands: Electronic, Geometric and Energetic Analysis
Density functional theory (DFT) (B3LYP/6-311++G(d,p)) calculations of the interacting strength 1,2-dithiolene anionic ligands with the [M(OH2)4]2+ and [M(OH2)2]2+ complexes (M = Ni and Zn) were performed. Three series of ligands were studied: compounds with an aromatic ring, with an ethylene moiety and with a heterocyclic ring. The ligands have substituents

12. New Synthesis Method for a Core-Shell Composite Based on α-Bi2O3 @PPy and its Electrochemical Behavior as Supercapacitor Electrode
New composite based on polypyrrole (PPy) and bismuth oxide (α-Bi2O3) was investigated as supercapacitor electrode. The α-Bi2O3 was obtained by hydrothermal route at 500 ºC for 2 h. Cyclic voltammetry was used to electropolymerize PPy on graphite electrode (GE) or on GE/α-Bi2O3. The X-ray diffraction profile of Bi2O3 revealed the α-Bi2O3 monoclinic struc
