(Universidade Federal de São Carlos, 2019-05-31)
The development of functional micro/nanostructures for use in the agricultural area is relevant and has the potential to reduce the consumption of inputs with improved efficiency of the final product. In this context, the ...
Análise do sistema Fe2O3 - SnO2 sinterizado: propriedade de transporte eletrônico
(Universidade Federal de São Carlos, 2019-09-30)
Hematite (α-Fe2O3) is a very abundant chemical compound in nature, has interesting electrical and magnetic properties, which consequently makes this oxide an advanced functional material. The literature reports that Sn ...
Avaliação do processo de vulcanização inversa visando a aplicação na produção de fertilizantes
(Universidade Federal de São Carlos, 2018-09-17)
Sulfur (S) is an essential macronutrient for crop development, nevertheless, its deficiency in agricultural soils has become increasingly alarming in the last decades. Despite elemental sulfur (S8) being a widely utilized ...
Desenvolvimento de filmes biodegradáveis baseados em pectina e nanofibras de celulose funcionalizadas
(Universidade Federal de São Carlos, 2019-08-26)
Renewable polymers are an interesting alternative to synthetic polymers from petrochemical sources. The work aims at the development of nanocomposite films based on pectin and functionalized cellulose nanofibers. The ...
Avaliação de diferentes rotas de encapsulamento de aromas em nanofibras poliméricas
(Universidade Federal de São Carlos, 2016-04-28)
The use of flavor has become increasingly common in the food and pharmaceutical industry, including menthol and ethyl hexanoate (EH) (main ester passion fruit aroma) has achieved prominence in the industry due to its ...
Estudo da corrosão atmosférica do aço AISI 1020 usando a técnica de ruído eletroquímico e microscopia óptica
(Universidade Federal de São Carlos, 2019-12-13)
The objective of this work was to study the corrosion of AISI 1020 exposed in an atmosphere containing acetic acid (HAc) vapor. Electrochemical noise (RE) oscillations and surface micrographs of the samples were obtained ...
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 ...
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. ...
