Estudo espectroscópico por FTIR da conversão de etanol em catalisadores de Au suportados
(Universidade Federal de São Carlos, 2020-07-25)
In this work, an FTIR spectroscopic study of gold catalysts supported on monoclinic zirconia (with Au content of 2,5% w/w), was carried out in order to elucidate the surface nature of this catalyst in the dehydrogenation ...
Síntese de miméticos da urease de Canavalia ensiformis e avaliação mecanística da decomposição da ureia
(Universidade Federal de São Carlos, 2020-02-20)
Urease is a metalloenzyme found in many different organisms, which is also associated to virulence factors, such as pielonefritis. Hence, the study of urease inhibitors is necessary to control its activity. For a better ...

(Universidade Federal de São Carlos, 2020-10-30)
16 sensing points for the construction of an array of biosensors. The components of this device have been individually evaluated and their construction design has been optimized for the best performance of the sensors. ...
Flow chemistry applied to hazardous reactions, and fluorophores synthesis with photophysics studies
(Universidade Federal de São Carlos, 2020-02-20)
Two distinct cases of continuous flow conditions applied to dangerous reactions are described. The first example is the continuous photooxygenation of a series of dienes that produces endoperoxides and / which are potentially ...
Síntese, caracterização e avaliação da atividade fotoeletrocatalítica de filmes finos de Sb2S3
(Universidade Federal de São Carlos, 2020-08-27)
Photoelectrochemical cells (PECs) have been shown to be a promising system for H2 generation from photoelectrolysis of water. Among the semiconductors materials that have been studied for PECs, Sb2S3 stands out due to its ...
Avaliação da atividade citotóxica de complexos fosfínicos de Ru(II) com ligantes mercaptos e aciltioureias
(Universidade Federal de São Carlos, 2020-12-11)
In this thesis, two series of new Ru-phosphine complexes containing mercapto or acylthiourea ligands were synthesized, characterized and assessed their cytotoxic activities. The first series is composed of five complexes ...
UVC-based advanced oxidation processes for water treatment: laboratory and pilot plant scale studies
(Universidade Federal de São Carlos, 2020-09-21)
The challenge of providing good-quality water free from contaminants of emerging concern (including organic microcontaminants; OMCs) and pathogens is one of the main hot topics worldwide. Thus, the efficiency of different ...
