A New, Friendlier Methodology to Determine the Average Manganese Valence in LixMn2O4 Spinels Using Atomic Absorption Spectrometry and Molecular Absorption Spectrophotometry
(Soc Brasileira Quimica, 2018-04-01)
An alternative, friendlier methodology for the determination of the average manganese valence (nu) of manganese oxides (mainly pure and doped spinels) is presented. This methodology is based on the facile determination of ...
Desenvolvimento de uma nova rota de síntese hidrotermal assistida por micro-ondas para a obtenção de nanopartículas de espinélios de manganês e lítio dopados com alumínio para aplicação em baterias de íons lítio
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Química - PPGQCâmpus São Carlos, 2018-03-01)
Spinel of manganese and lithium undoped and doped with aluminum were obtained by an unpublished, energy saving, short time, and low temperature synthesis: microwave-assisted hydrothermal route. Undoped spinel was synthesized ...
