Dopagem e formação de heterojunções como estratégias para o melhoramento da propriedade fotocatalítica de Ag3PO4
(Universidade Federal de São Carlos, 2022-06-27)
In recent years, the growing technological and industrial activities in sectors such as pharmaceuticals and textiles have shown side effects on the environment and human health. Such effects are related to the generation ...
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 ...
Estudos mecanísticos de reações de cicloadição e ciclização através de ferramentas experimentais e teóricas
(Universidade Federal de São Carlos, 2022-02-22)
Part 1: The 1,3-dipolar cycloaddition of nitroolefin and azides have emerged as an important approach for the synthesis of 1,2,3-triazole. We describe the rationalization of the regioselectivity/reactivity trends of this ...
Síntese de heterociclos nitrogenados através de reações de funcionalização C-H de azaarenos e avaliação da atividade antiparasitária
(Universidade Federal de São Carlos, 2022-01-28)
The neglected diseases caused by parasites, such as Chagas´ disease, sleeping sickness and leishmaniasis, affect thousands of people every year, mainly in tropical and underdeveloped countries. Due to the lack of efficient ...
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 de compostos N-heterocíclicos via fotocatálise
(Universidade Federal de São Carlos, 2022-03-18)
Heterocycles belong to a privileged class of organic compounds that play a
prominent role in chemistry and biology. There is an extensive literature about
methodologies for the synthesis of these substances, showing their ...
Síntese, caracterização e estudo catalítico de complexos miméticos das enzimas Nitrito Redutase e Anidrase Carbônica
(Universidade Federal de São Carlos, 2022-03-30)
Metalloenzymes are efficient biological catalysts that inspire the creation of coordination compounds that mimic their active site. In this work, the synthesized complexes were inspired by two enzymes: Nitrite Reductase ...
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)
The degradation of water bodies and the indiscriminate use associated with frequent and intense drought episodes have compromised the availability of water. Thus, the production of reused water from sewage treatment has ...
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 ...
