Determinação simultânea de íons metálicos utilizando voltametria de redissolução anódica e métodos de calibração multivariada
(Universidade Federal de São Carlos, 2010-10-14)
This work describes the determination of Cu2+, Cd2+, Pb2+, Zn2+ and Co2+ using electroanalytical techniques and analyzing the data with chemometric tools. First, an univariate approach was used to investigate RMSEParately ...
Atividades experimentais investigativas como contribuição ao desenvolvimento de modelos mentais de conceitos químicos
(Universidade Federal de São Carlos, 2013-02-22)
In this study, during the school year, the evolution of mental models from first grade high school students about different chemical concepts was investigated by the use of experimental inquiry activities. The research was ...
Materiais para aplicações eletroquímicas: otimização da síntese de grafeno/TiO2-RuO2 e estudo da retificação de corrente iônica em nanoporos
(Universidade Federal de São Carlos, 2020-05-19)
The current energy outlook points to the need to implement methodologies that value the reduction of energy consumption, as well as the use of cleaner and more sustainable processes of production, conversion, and storage ...
Estudo teórico de nano sistemas de azulenos: azulfenos, ANTs, poliazulenos e polinaftalenos
