Reaproveitamento de resíduos agroindustriais de frutas obtidos por meio de manejo convencional e orgânico: estudo de métodos para a extração verde e sustentável de compostos bioativos
(Universidade Federal de São Carlos, 2022-03-31)
The magnitude of the Brazilian agricultural and agro industrial market impresses by its greatness, but it is also the cause of serious concerns regarding the amount of waste generated and how to handle such residues. This ...
Detecção de impressões digitais por meio da luminescência autoativada de nanopartículas de fosfato de cálcio amorfo
(Universidade Federal de São Carlos, 2022-10-20)
In this work, stable activator-free photoluminescent nanoparticles based on amorphous calcium phosphate (ACP) were obtained for the first time, and their performance for latent fingerprint imaging was investigated. ACP ...
Funcionalização de 5-iodo-1,2,3-triazóis e síntese de seleno- e tioésteres por meio de reações de acoplamento carbonilativo empregando monóxido de carbono gerado ex situ
(Universidade Federal de São Carlos, 2022-06-06)
The use of pressurized carbon monoxide (CO) gas cylinders can lead to serious risks during their handling. Hence, the demand for safer carbonylation methods has been gradually increasing with the use of different techniques ...
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 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 ...
Estudo da remoção de contaminantes emergentes em estação de tratamento de esgoto equipada com biorreator acoplado a filtração por membrana: uma alternativa para a produção de água de reuso
(Universidade Federal de São Carlos, 2022-03-24)
