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 ...
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 ...
Catalisadores de Ni/Al2O3 promovidos com Au e Ag aplicados à reforma a vapor do metano
(Universidade Federal de São Carlos, 2005-04-08)
15%Ni/Al2O3 catalysts was obtained by impregnation with Ni(NO3)2
aqueous solution and promoted with Au and Ag. The Au was successively
impregnated with aqueous solution of [Au(NH3)4](NO3)3. The Ag was coimpregnated
with ...
Determinação experimental de Coeficientes de Atrito de diferentes partículas para aplicação na modelagem de escoamentos densos
(Universidade Federal de São Carlos, 2022-08-31)
Systems involving particles are very common in many engineering applications. The interaction between these particles and of them with the equipment surfaces can strongly affect their dis-tribution, which will often influence ...
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 ...

(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 ...
Inteligência computacional aplicada à modelagem matemática da produção de biossurfactantes por esterificação de ácidos graxos com açúcares
(Universidade Federal de São Carlos, 2024-02-16)
Because of increasing demand of biosurfactants, which are more environmentally friendly than to surfactants derived from non-renewable raw materials, there is a growing need for studies proposing new processes for their ...
Modelagem fuzzy-cinética e monitoramento espectrofotométrico da hidrólise enzimática do bagaço de cana-de açúcar em sistema de reatores com separação de fases
(Universidade Federal de São Carlos, 2024-02-27)
The decrease in fossil fuel reserves combined with the growing global energy demand fosters
the search for alternatives. Within this scope, a possible solution may arise from the use
of biofuels, such as ethanol, produced ...
Estudo da reação de hidrogenação de CO2 para a síntese de álcoois em catalisadores à base de Cu e Co
(Universidade Federal de São Carlos, 2024-02-28)
CO2 is a gaseous chemical compound important for maintaining life on Earth, being used in the photosynthesis process by plants, which forms glucose and releases oxygen into the atmosphere. Furthermore, it is the main ...
Controle da poluição do ar por filtração híbrida de material particulado proveniente da indústria siderúrgica
(Universidade Federal de São Carlos, 2024-08-12)
The transmission of specific material by industry poses a serious threat to the environment
and human health. The World Health Organization (WHO) World Health Statistics report of
2018 revealed that air pollution was ...
