Obtenção de sulfetos metálicos (M= Ni, Mo) pelo método solvotermal assistido por micro-ondas aplicados na reação de desprendimento de hidrogênio
(Universidade Federal de São Carlos, 2020-03-27)
In general, transition metal sulfides show good activity in the Hydrogen Evolution Reaction (HER). Some of these metals, such as Mo and Ni, arouse interest in the area of electrocatalysis, since they are more abundant and ...
Metabolic discrimination of citrus species resistant and susceptible to black spot disease using multi-platform-based metabolomic approach
(Universidade Federal de São Carlos, 2020-08-31)
Citrus black spot (CBS) caused by the fungus Phyllosticta citricarpa. CBS causes several economic damages to commercial citrus orchards, such as fruit blemishes and premature fruit drop, leading to yield loss. There are ...
Calibration strategies for elemental determination using direct solid analysis by x-ray spectroscopy and laser-induced breakdown spectroscopy
(Universidade Federal de São Carlos, 2020-07-30)
Direct analysis of solid samples using techniques such as wavelength dispersive X-ray fluorescence (WD XRF), X-ray absorption near-edge structure (XANES) spectroscopy and laser-induced breakdown spectroscopy (LIBS); have ...
Caracterização das interações químicas entre os microrganismos simbiontes das formigas cortadeiras
(Universidade Federal de São Carlos, 2021-01-13)
The complex symbiosis in Attini ant nests inspires curiosity in different fields of research from Microbiology to Chemical Ecology. These ants cultivate their mutualist fungus for approximately 50 million years in structures ...
Desenvolvimento de dispositivo microfluídico descartável contendo arranjos de biossensores para a determinação multiplexada de espécies de interesse biológico em diferentes matrizes
(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. ...
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 ...
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 ...

(Universidade Federal de São Carlos, 2021-02-23)
In this work, the bactericidal, antiprotozoal, and inhibition of cathepsin V proteolytic activity of extracts from the axenic cultivation of six fungal species (Fusarium guttiforme, Pestalotiopsis diospyri, Phoma ...
Sachês compósitos biodegradáveis à base de amido visando o acondicionamento de nutrientes para aplicação como fertilizantes
(Universidade Federal de São Carlos, 2020-07-31)
The Brazilian agrarian system is responsible for a large part of the national GDP, even though agricultural production is dependent on foreign trade. In addition, many producers prioritize the use of NPK-type fertilizers ...
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 ...
