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 ...
Síntese de compostos C2+ a partir de CO2 e H2O aplicando materiais de Cu e Cu-Zn: estudos na catálise heterogênea em fase gasosa e eletrocatálise
(Universidade Federal de São Carlos, 2020-08-25)
Strategies aimed at recycling of CO2 in producing chemicals and fuels are needed to reduce the environmental impacts caused by this gas and attend the industrial interests. Among the all applied strategies, we highlight ...
Catalisadores de CuO/CeO2 promovidos com Au e Pt - estudo do impacto da interface e das propriedades eletrônicas do Cu no desempenho catalítico na reação de CO-PROX
(Universidade Federal de São Carlos, 2020-05-06)
The copper-ceria system has been extensively investigated to be used as a catalyst in the preferential oxidation of CO reaction (CO-PROX), aiming the purification of H2 streams from reformed fuels, due to its oxygen storage ...
Cellulose nanomaterials isolated via enzymatic and mechanical routes for application in hydrogels
(Universidade Federal de São Carlos, 2021-11-10)
The integrated production of different bioproducts has been considered essential to make biorefineries economically viable. Among the bioproducts, cellulose nanomaterials (CNs) have attracted significant attention due to ...
Análise técnico-econômica-ambiental da produção de nanocelulose em biorrefinarias de cana-de-açúcar
(Universidade Federal de São Carlos, 2021-08-31)
The production of ethanol, sugar and energy in Brazilian sugarcane biorefineries
generates a large number of residues, such as bagasse and straw. An alternative is the
reuse of these residues as feedstock for obtaining ...
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, ...
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 ...
O efeito do potássio (K) na formação de CH4 na reação de reforma a vapor e sua relação com a estrutura da molécula reformada
(Universidade Federal de São Carlos, 2021-10-29)
Nickel (Ni) catalysts were applied in the steam reforming reaction of organic compounds. Ni is highly active for breaking C-C bonds, a route in steam reforming reactions to generate hydrogen (and CO), however it is also ...
Intermittent drying and draft tube design for spouted bed
(Universidade Federal de São Carlos, 2021-12-08)
The conventional spouted bed has presented several limitations that restrict the use on an industrial scale. Thus, studies of different methodologies and configurations have been performed to overcome such limitations. ...
Synthesis of isoamyl esters from soybean oil deodorizer distillate by enzymatic catalysis for biolubricant applications
(Universidade Federal de São Carlos, 2022-07-26)
Lubricants are among the many products whose manufacture is highly dependent on nonrenewable fossil resources, with high levels of production and a vast marketplace, so they are the focus of many environmental laws around ...
