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 ...
Desenvolvimento de banhos para eletrodeposição de ligas Zn-Fe-P e Zn-Ni-P
(Universidade Federal de São Carlos, 2015-03-30)
In this work, an alkaline and an acid bath, both containing sorbitol, for electrodeposition of Zn-Fe-P on Pt were developed. Furthermore, we also developed an acid bath, containing sorbitol and H3BO3 for electrodeposition ...
Compósitos nanoestruturados baseados em polímero condutor/cerâmica como plataforma sensorial para detecção de gás amônia
(Universidade Federal de São Carlos, 2017-04-20)
The development of novel nanostructured platforms for application as gas sensor has intensified over the last few decades. In this scenario, it is worth mentioning the importance of monitoring ammonia gas in poultry farms. ...
