(Bi13Co11)Co2O40–Co3O4 nanocomposites: Approach to different fuels in sol-gel combustion synthesis using the Box-Behnken design
Autor: Ademir Oliveira da Silva, João Bosco Lucena de Oliveira, Djalma Ribeiro da Silva, Jefferson A. Lopes Matias, Marco A. Morales, Isaac Barros Tavares da Silva
Publikováno v: Ceramics International. 48:481-494
The sol-gel combustion method was applied using three types of fuels (urea, glycine, and ethylene glycol) to synthetize Co sillenite. A Co sillenite - Co3O4 nanocomposite was obtained as result of the synthesis. The effects of initial pH, fuel type,

(Bi13Co11)Co2O40–Co3O4 nanocomposites: Synthesis, characterization and application as substrate for microstrip patch antenna
Autor: Matheus Emanuel Tavares Sousa, Marco A. Morales, Jefferson A. Lopes Matias, Isaac Barros Tavares da Silva, João Bosco Lucena de Oliveira, Djalma Ribeiro da Silva
Publikováno v: Ceramics International. 47:21530-21535
The sillenite-cobaltite nanocomposites with chemical formula (Bi13Co11)Co2O40–Co3O4 were synthetized and characterized for application as substrate in a microstrip patch antenna. To prepare the sample, the combustion method using urea as fuel was a
