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 ...
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 ...
Estudo empírico-teórico de compósitos baseados em polímeros condutores para conversão e armazenamento de energia
(Universidade Federal de São Carlos, 2018-10-26)
The fast obsolescence of still functional devices causes an extensive e-waste generation and an exacerbated natural resources consumption for the manufacture of new products. In this sense, the development of abundant ...
Obtenção de sachês biodegradáveis de amido reforçados com nanopartículas de CuO para liberação de nutrientes minerais
(Universidade Federal de São Carlos, 2020-12-18)
Fertilizers have been used as agricultural inputs to allow maximum yield during the growth of crops. One of the significant challenges is the efficiency of the plant's nutritional process. It is necessary to use excessive ...
Desenvolvimento de plataformas nanométricas híbridas baseadas em polímero/enzima visando aplicações em biossensores
(Universidade Federal de São Carlos, 2016-10-27)
Foodborne illness cases are common in Brazil and in the world. However, in many cases the microorganism causing the illness cannot properly identified. In addition, traditional analyses usually employed for identifying ...
Estudo da ruptura dielétrica durante a anodização de zircônio e o seu efeito sobre o processo de dopagem anódica de ZrO2
(Universidade Federal de São Carlos, 2012-05-09)
In this work the fundamental aspects of electrolytic breakdown in ZrO2 films were investigated. The electrolytic breakdown is a type of dielectric breakdown that occurs during galvanostatic growth of anodic oxides. To ...
Hidrogéis Nanocompósitos Termossensíveis aplicados no crescimento de Células–tronco Mesenquimais e Condrócitos para a engenharia tecidual
(Universidade Federal de São Carlos, 2018-09-27)
Injectable biomaterials have gained prominence in tissue engineering since they present a minimal invasive option for therapeutic delivery. However, longer gelation time, instability of physicochemical properties, cytotoxicity ...
Hidrogéis magneto-reponsivos para liberação estimulada de fármacos
(Universidade Federal de São Carlos, 2018-05-08)
Nanocomposite hydrogels modified with polysaccharides, minerals clay and magnetic nanoparticles of iron oxide functionalized with polymeric material were developed, allowing higher interaction between the nanoparticles and ...
Estudo do SnO2 como fotocatalisador para a degradação da rodamina B: fatores limitantes e estratégias para aumento da fotoatividade
(Universidade Federal de São Carlos, 2018-01-19)
The photocatalytic activity of SnO2 was assessed according to the surface processing used for its surface activation. Mechanical activation by grinding and hydrothermal treatments under different conditions were applied ...
Estudo do potencial eletrostático e da termodinâmica de agregação de surfactantes por simulações de dinâmica molecular
(Universidade Federal de São Carlos, 2018-03-13)
Due to the amphiphilic character, the surfactants tend to be adsorbed at the water surface and, in concentrations larger than the critical micellar concentration, they self-assembling in solution with the purpose to reduce ...
