Modelagem matemática e simulação computacional aplicadas ao estudo de processos de co-digestão anaeróbia de glicerol e/ou melaço
(Universidade Federal de São Carlos, 2022-11-29)
Policies worldwide are increasingly incentivizing and pressuring countries to use renewable sources of energy. Brazil was a pioneer in the production of bioethanol and is one of the main producers of biodiesel. Due to the ...
Avaliação do processo de produção de colorante natural vermelho pelo fungo endofítico Talaromyces minnesotensis
(Universidade Federal de São Carlos, 2022-06-29)
The growing incentive and awareness regarding the consumption and use of more sustainable proposals, biocolorants from filamentous fungi are presented as a promising alternative to synthetic colorants. These biocompounds ...
Development of filter media from cellulose acetate polymer containing silver nitrate (AgNO3)
(Universidade Federal de São Carlos, 2024-04-30)
This master's thesis provides a thorough analysis of the creation of nanofiber media with enhanced antibacterial characteristics that are integrated with cellulose acetate polymer and silver nitrate (AgNO3). The study ...
Oxidação do metano em metanol: efeito da natureza do oxidante na estrutura da espécie ativa em Cu-FAU e Cu-CHA
(Universidade Federal de São Carlos, 2023-02-27)
The direct oxidation of methane to methanol is carried out with metal-zeolite catalysts in three steps: (I) oxidation of metal oxide with O2; (II) partial oxidation of methane to methanol using active site oxygen, and (III) ...
Efeito da acessibilidade aos sítios ácidos da Zeólita MFI na esterificação catalítica
(Universidade Federal de São Carlos, 2023-11-24)
In the context of increasing ethanol production through fermentation, substantial amounts of fusel oil are produced. Consequently, there is a growing interest in exploring methods to reuse fusel oil by transforming its ...
Produção e purificação de nanotubos de carbono via decomposição catalítica do metano
(Universidade Federal de São Carlos, 2024-02-23)
Carbon nanotubes (CNTs) are materials with the potential to develop disruptive technologies, such as the construction of space elevators and transistors smaller than silicon, but their production is still an engineering ...
Novas abordagens para aumentar a sobrevivência e eficiência de cepas de Bacillus solubilizadoras de fosfato
(Universidade Federal de São Carlos, 2024-04-12)
NEW APPROACHES TO INCREASE THE SURVIVAL AND EFFICIENCY OF PHOSPHATE- SOLUBILIZING BACILLUS STRAINS. In a context where global population growth and the exacerbated impacts of climate change pose critical challenges to food ...
Valorizando subprodutos das produções de óleo de soja e etanol: síntese e análise técnico-econômica da produção de biolubrificantes em biorrefinarias
(Universidade Federal de São Carlos, 2024-02-23)
Despite oil-based products still dominate the market, there is a growing use of bio-based alternatives (called biolubricants) enhanced with chemical modifications. The main paths for the production of these biolubricants ...
Nanofibras biodegradáveis eletrofiadas aplicadas à filtração de ar do SARS-CoV-2 Simulado
(Universidade Federal de São Carlos, 2024-05-27)
One of the lasting outcomes of the COVID-19 pandemic was the production and
deposition of plastics. These materials, particularly disposable face masks, end up in the
environment, releasing microplastics and other ...
Filmes poliméricos a base de carboximetil celulose reforçados com nanocelulose com potencial para encapsular o agente de biocontrole Trichoderma harzianum
(Universidade Federal de São Carlos, 2024-02-28)
The use of microorganisms for pest and disease biocontrol in plants represents an environmentally friendlier alternative to agrochemicals, potentially contributing to the development of more sustainable agriculture. Among ...
