Modelagem matemática para sínteses enzimáticas de biossurfactantes catalisadas por lipases imobilizadas
(Universidade Federal de São Carlos, 2021-07-08)
Enzymatic reactions of esterification of fatty acids with carbohydrates generate biosurfactants, products with high capacity to reduce surface and interfacial tensions, applicable mainly in the food, pharmaceutical and ...
Oxidação direta de metano a metanol sobre espécies [CuxOy] incorporadas em zeólitas ferrierita
(Universidade Federal de São Carlos, 2021-05-06)
The development of technologies to minimize the CO2 emissions, which are generated by the indiscriminate burning of fossil fuels, remains a relevant research topic in the context of the planet's sustainability. Thus, it ...
Estudos sobre a acessibilidade aos sítios de zeólitas para aplicação em catálise básica
(Universidade Federal de São Carlos, 2022-03-28)
The application of zeolites in catalysis is restricted when bulkier molecules are involved, for example, in the manufacture of fine chemicals, where the reactant molecules are unable to access their micropores. A solution ...
Produção de meios filtrantes a partir de garrafas PET recicladas para aplicações em filtração de ar com alta eficiência de coleta de nanopartículas através da técnica de Electrospinning
(Universidade Federal de São Carlos, 2021-07-29)
Air pollution and solid pollution are considered global problems, and endanger human health mainly due to the improper disposal of solid wastes, as the post-consumer plastic botlles.. The filtration process using fibrous ...
Aproveitamento de CO2 para a produção de metanol e compostos C2+ aplicando catalisadores à base de Cu e Fe
(Universidade Federal de São Carlos, 2021-08-10)
Considering the approaches to use of the CO2, this work aimed to study CO2 hydrogenation at gas phase and CO2 reduction (CO2RR) via electrocatalysis. Through these methodologies a wide variety of value-added products can ...
Análise de diferentes configurações do leito de jorro com agitador mecânico e do equipamento convencional
(Universidade Federal de São Carlos, 2022-03-24)
The mechanical spouted bed emerged as a modification of the conventional spouted bed
to minimize problems in the movement of solids and the need for high air flows just for
the existence of the spouting regimen. Therefore, ...
Contribuição ao estudo termodinâmico das soluções de ácido acetilsalicílico
(Universidade Federal de São Carlos, 2007-09-20)
As one of the most regularly traded-in medicines in the world, the acetylsalicylic acid
has been scarcely researched when in solution. This study is aimed at determining the
thermodynamic equilibrium parameters for ...
Catalisadores Ni/SBA-15 com adição dos promotores aplicados a tri reforma do metano
(Universidade Federal de São Carlos, 2021-10-27)
Tri-reforming of methane (TRM) is a combination of steam and dry reforming and partial oxidation of methane reactions in the same reactor. Since it occurs at high temperatures and has water vapor in the reactor feed, TRM ...
Influência do agente precipitante na síntese de catalisadores Cu-ZrO2 aplicados na conversão de glicerol a acetol e propilenoglicol
(Universidade Federal de São Carlos, 2021-07-23)
Biodiesel production by transesterification reaction generates large amounts of glycerol as a by-product. The development of chemical routes to use glycerol as raw material for products with high added value is essential ...
Produção de esferoides de células tumorais de câncer de bexiga num biorreator de vórtice de Taylor
(Universidade Federal de São Carlos, 2018-03-08)
Two-dimensional (2D) cell culture has been the common platform for evaluating anticancer drugs. However, three-dimensional (3D) cell cultures, such as multicellular tumor spheroids (MCTS), best resemble tumor in vivo ...
