Influência da costura na performance de meios filtrantes aplicados em filtro de mangas
(Universidade Federal de São Carlos, 2022-08-30)
There is a variety of filter bags available in the market for cleaning gases, composed of different materials, of various sizes, with several surface treatments, high efficiency, and different finishes, which enables the ...
Formação do carbonato de glicerol por transesterificação catalítica heterogênea
(Universidade Federal de São Carlos, 2022-04-29)
The industrial production of biodiesel has generated large amounts of glycerol, transforming this co-product into raw material for other processes. Notably, glycerol carbonate has emerged as a promising substance for the ...
Utilização do CO2 em substituição ao O2 na ativação de Cu-MAZ na oxidação do metano a metanol
(Universidade Federal de São Carlos, 2022-10-27)
Converting methane to methanol has been a challenge for decades due to the high reactivity of methanol compared to methane. One of the challenges of this reaction to take it to an industrial scale was to find a safer oxidant ...
Implementação de sistema nebuloso (“fuzzy”) para controle de oxigênio dissolvido no cultivo de Escherichia coli para expressão de proteínas recombinantes
(Universidade Federal de São Carlos, 2022-04-27)
Due to low oxygen solubility in water and mechanical limitations of a bioreactor, ensuring an adequate dissolved oxygen supply during a recombinant Escherichia coli cultivation is a major challenge in process control. In ...
Development of integrated strategies using non-recombinant yeast for 2G ethanol production from lignocellulosic materials
(Universidade Federal de São Carlos, 2023-01-31)
The viability of second-generation (2G) ethanol production still requires overcoming some bottlenecks, such as the underutilization of the hemicellulosic fraction of biomass and process improvements to reach higher ...
Avaliação da fermentação alcoólica extrativa em diferentes temperaturas com remoção de etanol por arraste com CO2
(Universidade Federal de São Carlos, 2023-02-23)
By reducing the fermentation temperature, the inhibitory effect of ethanol is also reduced, resulting in wines with higher ethanol contents, but with a significant decrease in ethanol productivity, due to the negative ...
Encapsulamento de Trichoderma harzianum em matrizes à base de nanocelulose e carboximetilcelulose para aplicação na agricultura
(Universidade Federal de São Carlos, 2023-06-21)
Microbial inoculants are a sustainable alternative to increase agricultural productivity and reduce environmental and health problems caused by the exacerbated use of agrochemicals. These bio-based products are formulations ...
Compreendendo a reação ‘step-wise’ de conversão de metano a metanol usando zeólitas trocadas ionicamente com cobre
(Universidade Federal de São Carlos, 2020-03-06)
Methane (CH4) is a stable molecule abundantly found on our planet with reserves even
greater than crude oil. Due to its high availability and environmental impacts caused by
its emission into the atmosphere, the development ...
Immobilization of enzymes of agroindustrial interest on hydroxyapatite nanoparticles: β-glucosidase, xylase and phytase
(Universidade Federal de São Carlos, 2020-03-10)
Industrial processes are increasingly requiring environmentally sustainable technologies and the use of enzymes is relevant due to the selectivity and specificity of these biocatalysts. However, the application of soluble ...
Niobium-based oxides for oxidative and reductive photocatalytic reactions
(Universidade Federal de São Carlos, 2020-02-21)
It is growing the number of studies related to alternative technologies allowing both, environmental remediation and clean energy production. In this sense, photocatalysis is a promising process, since it is sustainable ...
