Some features of the mechanism of the anode process on platinum in KF–NaF–AlF3–Al2O3 melt at 750-780 °C depending on the of anodic current density (0.5 mA/cm2 to 2.0 A/cm2) and anodic pulse duration have been studied using chronopotentiometry method. In c... see more

Methods potentiostatic polarization and cyclic voltammetry obtained new data on the mechanism and kinetics of anodic processes on platinum in the molten CaCl2-KCl-CaO when 725–775 °C. Given thermodynamic values of potential difference probable total ... see more

The current practice in the field of anodic oxidation of aluminium and its alloys is based mainly on a set of partial empirical experiences of technologists obtained during surface treatment. The aim of the presented paper is deeper and more complex ident... see more

Most learners are less able to understand lessons in distance learning, so it is very necessary for teacher guidance to follow learning through observation, experimenting, and active experiments. The purpose of this study is to analyze the effectiveness o... see more

The COVID-19 pandemic has led to drastic changes in all spheres of life. In terms of education, the pandemic modified the way of teaching and learning. To meet the demands of new circumstances, the priorities shifted towards the implementation of online t... see more

Introdução: Gerenciar problemas relativos à organização da informação é uma tarefa árdua e dispendiosa, uma vez que demandam conhecimentos específicos, metodologias apropriadas e ferramentas adequadas. Neste contexto, as ontologias e a modelagem de proces... see more

This study focused mainly on the color removal of textile azo dye Reactive Orange 16 (RO16) by electrochemical oxidation. The effect of supporting electrolyte (H2SO4 and NaOH), RO16 concentration (from 0.5 to 10 mM) and potential scan rate (between 20 and... see more

The aim of this article is to present a methodological model to analyze students' group interaction to improve their essays in online learning environments, based on asynchronous and written communication. In these environments teacher and student scaffol... see more
