Estudo teórico: da adsorção de etanol em clusters de Cun e Aun (n = 10-20)
(Universidade Federal de São Carlos, 2021-08-24)
In this work, we study aggregates, which we will call clusters of copper and gold with and without the adsorbed ethanol molecule. First, we investigated the most favorable positions for ethanol adsorption to occur in ...
Determinação de pesticidas organoclorados e fármacos em matrizes ambientais utilizando QuEChERS, extração líquido-líquido (LLE) e extração em fase sólida (SPE)
(Universidade Federal de São Carlos, 2021-11-24)
The presence of xenobiotic organic contaminants in water bodies, where arrive from releases of treated or untreated effluent, has raised concerns
about impacts related to the richness and biodiversity of aquatic life and ...
Esfoliação e funcionalização de nanofolhas de MoS2: desenvolvimento de novos materiais elastoméricos
(Universidade Federal de São Carlos, 2021-09-30)
Two-dimensional materials, such as MoS2, have been extensively studied in recent decades due to their excellent properties in electronics, electrocatalysis, optics and mechanics. A major focus in recent research resides ...
Performance optimization in redox flow batteries: a computational approach
(Universidade Federal de São Carlos, 2022-02-22)
Redox flow batteries (RFBs) emerge as an alternative technology for the storage of energy on a large scale. The main characteristics of this type of device are related to its unique design, which provides scalability, ...
Reações de fotooxigenação de pinenos em pinocarvonas, trans-pinocarveóis e mirtenal: uma abordagem em regime de fluxo contínuo
(Universidade Federal de São Carlos, 2022-04-18)
In this work, a continuous flow protocol to prepare (-)-pinocarvone, (-)-trans-
pinocarveol and (+)-myrtenal from (+)--pinene, (-)--pinene and -pinene through
photooxygenation reactions was described. Furthermore, ...
Avaliação de eletrodos compósitos de MnO2 e carbono ativado para aplicação em supercapacitores
(Universidade Federal de São Carlos, 2022-11-30)
Evaluation of composite Mno2 and activated carbon electrodes for application in supercapacitors. Manganese dioxide (MnO2) nanoparticles were synthesized by microwave-assisted hydrothermal methodology and characterized by ...
Espalhamento elástico de elétrons e ionização dissociativa da molécula de trimetil fosfato
(Universidade Federal de São Carlos, 2021-09-28)
The trimethyl phosphate molecule is an important prototype for studying electron interactions with molecules of biological significance containing the phosphate group. These studies contribute to the understanding of energy ...
Desenvolvimento de catalisadores bifuncionais a base de fosfato e suas aplicações catalíticas
(Universidade Federal de São Carlos, 2022-02-17)
The development of bifunctional acid catalysts is an area of heterogeneous catalysis in intense growth, mainly due to the possibility of performing consecutive reactions using a single catalyst and a single reactor. In ...
Polipropileno reciclado para contato com alimento: etching e deposição de filmes de carbono amorfo hidrogenado por plasma
(Universidade Federal de São Carlos, 2020-09-30)
The increasing applications of polymers make this material one of the most consumed in the world market. Accompanying this scenario is the generation of waste, and although plastic has gradually conquered its space as a ...
