Mecanismos eletroquímicos nos processos de descarga do sistema PbO2/H2SO4
(Universidade Federal de São Carlos, 2017-11-17)
The goal of this work was to seek a mechanistic and morphological understanding of the discharge process of lead-acid batteries’ positive plates, which exhibits a complex porous structure. Due to this fact, nonporous ...
Avaliação das propriedades antitumorais de complexos de rutênio(II) contendo os ligantes lapachol ou lausona
(Universidade Federal de São Carlos, 2018-06-29)
Metal complexes containing ligands that present biological activity have been attracting interest in the field of development of new drugs for the treatment of cancer. Lapachol and lawsone are examples of important natural ...
Estudo mecanístico de reações de estado sólido: o caso do sistema Pb/PbSO4/Na2SO4
(Universidade Federal de São Carlos, 2012-11-21)
In this work, the growth and reduction of PbSO4 in Na2SO4 solution under transient conditions was characterized. A novel methodology for the working-electrode surface preparation before stabilization enhanced the voltametric ...
Materiais híbridos condutores baseados em grafeno/polímero visando aplicações em monitoramento e remediação de poluentes ambientais
(Universidade Federal de São Carlos, 2018-10-23)
Graphene is a material composed of a single layer of carbon atoms arranged in rings of six atoms with sp2 hybridization. Graphene displays a high sensitivity towards several molecules. Additionally, graphene presents other ...
Estudo das propriedades estruturais, ópticas e fotoluminescentes do Sistema α-(Ag2-3x-yTRxLiy)WO4 (TR = Pr, Sm, Eu, Tb, Dy e Tm)
(Universidade Federal de São Carlos, 2018-08-17)
Luminescent materials of different colors emission are of great interest for development of new or more efficient optical devices. Although many materials have been reported using different approaches, green synthesis and ...
