Propriedades estruturais e eletrônicas de nanopartículas de Cu modificam a estrutura superficial do cobre e influenciam na atividade catalítica para a reação deslocamento gás água
(Universidade Federal de São Carlos, 2017-08-16)
The Cu catalysts activity is modified by reducible supports, such as cerium and praseodymium oxides. The interaction of these oxides with Cu nanoparticles prevent agglomeration and generate active interface sites. The ...
Modelagem, simulação e análise técnico-econômica-ambiental do processo de extração de óleo de soja por hexano e etanol e da produção de biodiesel
(Universidade Federal de São Carlos, 2019-07-04)
Brazil is the second largest producer of soybean, with the projection of becoming the largest producer in 2019/2020. All Brazilian soybean oil is produced by the extraction process with hexane, an oil derivative. One way ...
Particle image velocimetry and computational fluid dynamics applied to study the effect of hydrodynamics forces on animal cells cultivated in Taylor vortex bioreactor
(Universidade Federal de São Carlos, 2016-03-28)
Taylor-Vortex reactor (TVB) is fast becoming the next bioreactor to culture animal cells due to milder shear and homogeneous flow structures through-out the bioreactor in comparison to the traditional stirred vessels. ...
Síntese de adsorventes magnéticos utilizando casca de soja e sua aplicação na adsorção de ácido cafeico
(Universidade Federal de São Carlos, 2018-12-11)
Wastewater management has gained increasingly space on the world stage, with significant advances in both the environmental and financial spheres. Phenolic compounds are present in wastewater of various processes, such as ...
Partículas rugosas de sílica híbrida aplicadas na transesterificação catalítica
(Universidade Federal de São Carlos, 2019-03-15)
Heterogeneous catalysts are potentially responsible for reducing the cost of producing biodiesel, due to its reusability or use in continuous process. As-synthesized hybrid silicas, containing siloxy sites, can be used as ...
Preparação e caracterização de sílicas híbridas com surfactantes catiônicos
(Universidade Federal de São Carlos, 2018-02-16)
The silica with structure MCM-41 has a hexagonal mesoporous arrangement with one dimensional pore system. This silica as synthesized contains cations (usually the CTA+) in your pores and catalytic sites with basic character ...
Catalisadores de Ni suportados em óxidos sintetizados com líquido iônico: atividade catalítica na tri-reforma do metano
(Universidade Federal de São Carlos, 2019-04-11)
Tri-reforming reaction is a new method to use and convert CO2 from industrial plants effluents. The tri-reforming involved reactions are two endothermic reactions, the steam and dry reforming and the partial methane oxidation ...
Aspectos morfológicos, reológicos e fisiológicos dos cultivos de Escherichia coli recombinante
(Universidade Federal de São Carlos, 2015-04-30)
The use of Escherichia coli cultures to obtain heterologous proteins poses as a successful application of biotechnology for the production of drugs and enzymes. However, the stress caused by the synthesis of the recombinant ...
Análise do material particulado na área central da cidade de São Carlos-SP através de técnicas espectroanalíticas e avaliação multidimensional de séries temporais
(Universidade Federal de São Carlos, 2019-05-23)
Due to the worldwide trend of industrialization and urbanization, air pollutants are emitted large
quantities on a global scale, particularly in developing countries, which produces adverse
effects on human health by ...
Preparação, caracterização e aplicação de eletrodos tridimensionais de carbono vítreo reticulado recobertos com filmes de PbO2 para a degradação do corante reativo AR 19 e glifosato
(Universidade Federal de São Carlos, 2016-05-06)
Electrodeposition of a PbO2 film was performed onto reticulated vitreous carbon (RVC)
substrates with porosities of 45, 60, and 80 ppi, at 65 ºC in a flow reactor, starting with a
solution containing Pb(NO3)2, surfactant, ...
