Sensores nanoestruturados compostos por nanofibras de dióxido de titânio modificadas com polímeros condutores visando monitoramento de compostos orgânicos voláteis
(Universidade Federal de São Carlos, 2020-03-18)
The growth of urbanization and anthropogenic activities have been increasing the emission of polluting gases in the atmosphere. Considering the high toxicity of some of these gases, it becomes necessary to develop new ...
Estudo microestrutural dos contornos de grão em estágio inicial de formação no sistema cerâmico ZnO-Bi2O3
(Universidade Federal de São Carlos, 2019-08-28)
Polycrystalline materials have solid-solid interfaces known as grain boundary. These interfaces have long been treated as just a region of defects between the crystals (grains), but recent studies have shown that such ...
Produção de Na-β″-alumina e o seu transporte iônico do Na+
(Universidade Federal de São Carlos, 2019-02-25)
In the present doctorate thesis, in order to study the Na+ ion transport in Na-βʺ-alumina(cr), we started by studying the production stages of Na-βʺ-alumina(cr) sodium ion conductive membranes. In order to do so, we studied ...
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 ...
Sistema híbrido eletroquímico–fotoquímico para a mineralização do herbicida tebutiuron
(Universidade Federal de São Carlos, 2016-02-24)
An electrochemical-photochemical system (EC-PC)
using a dimensionally stable anode (DSA®) was used to oxidize and mineralize
tebuthiuron (TBT) herbicide, which is a potential contaminant to the surface and
ground water. ...
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 ...
Cinética de liberação de clorexidina em nanocompósito de magnetita e quitosana
(Universidade Federal de São Carlos, 2019-04-03)
Nanocomposites are used in several fields of knowledge, including nanomedicine. They are used as drug carriers because of their biocompatibility and biological activity, with possible antimicrobial activity. This study ...
