Atomic-Scale Structure of Biogenic Materials by Total X-ray Diffraction: A Study of Bacterial and Fungal MnOx
(AMER CHEMICAL SOC, 2009)
Biogenic materials are produced by microorganisms and are typically found in a nanophase state. As such, they are difficult to characterize structurally. In this report, we demonstrate how high-energy X-ray diffraction and ...
Development of an electrochemical sensor based on nanostructured hausmannite-type manganese oxide for detection of sodium ions
(2013-03-25)
The preparation and electrochemical characterization of hausmannite-type manganese oxide to use as a sensing material for sodium ion is described. This paper reports a new via synthetic to obtain of the hausmannite-type ...

Desarrollo de materiales semiconductores funcionales basados en óxidos de manganeso
(2012)
En el presente trabajo se sintetizaron materiales laminares de óxido de manganeso tipo birnesita y buserita (materiales tipo Octahedral Layer, OL -1) por un proceso de oxidoreducción, los cuales luego fueron modificados ...
Obtención de morteros pigmentados a base de óxidos de hierro naturales
(Universidad de la CostaIngeniería Civil, 2019)
Síntese hidrotérmica aquecida por micro-ondas e caracterização por raios X baseada em síncrotron operando de nanopartículas de LiMn2O4 enriquecidas com Li e dopadas com Al, Co ou Ni para aplicação em baterias de íons lítio
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Química - PPGQCâmpus São Carlos, 2022-05-24)
A facile, fast and efficient microwave-assisted hydrothermal (MWH) route was used to synthetize undoped and doped spinels with Al or Co or Ni. The reaction was carried at low temperature of 140 °C for 5 min in an MWH reactor ...
