Crescimento anódico e caracterização de óxidos coloridos de titânio em eletrólitos alternativos
(Universidade Federal de São Carlos, 2015-01-23)
A Studies on the anodic growth of oxides that passivate the biomaterial titanium, and their electrochemical, morphological and structural parameters were carried out in this work. The oxides were obtained galvanostatically ...
Determinação simultânea de íons metálicos por meio de técnicas eletroanalíticas e quimiométricas
(Universidade Federal de São Carlos, 2011-05-19)
In this work, the determination of three metallic ions was performed, namely Zn2+, Cd2+ and Pb2+, in very different concentration range, from _g/L until mg/L, using differential pulse anodic stripping voltammetry over ...
Estudo do efeito isotópico sobre a solubilidade da 3- metilpiridina em H2O e D2O
(Universidade Federal de São Carlos, 2012-12-07)
Experimental studies of 3-methylpiridyne/water and 3- methylpiridyne/heavy water binary mixtures show solubility differences. In this work Molecular Dynamics method was used to simulate 54 model systems. Each system ...
Estudo da estrutura de complexos de polieletrólitos sobre as propriedades de transporte de água e sais
(Universidade Federal de São Carlos, 2015-03-25)
Polyelectrolytes complexes (PECs) are defined as materials formed by combining oppositely charged polyelectrolytes together via ionic interaction. PECs have some unique physical properties such as non-solubility in common ...
