Arilsulfonilação tri componente de diidrofurano e ésteres vinílicos via catálise dual níquel/fotorredox
(Universidade Federal de São Carlos, 2022-03-29)
The pursuit of synthetic protocols aligned to sustainability goals, increasingly necessary in the global context in which we operate, caused a great effort by synthetic chemists to develop photocatalytic methodologies ...
Oxidação eletroquímica de 5-hidroximetilfurfural e glicose: adsorção em Pt (111) e Pt (110) e fotocatálise em BiVO4
(Universidade Federal de São Carlos, 2023-11-24)
The exponential increase in energy demand has generated the need to develop more efficient methods based on renewable energy sources. One way to achieve this goal is storing the solar energy through chemical bonds, with ...
Influência do tipo de lipídeo e peptídeo beta amiloide sobre a perturbação da membrana e consequências na toxicidade de células neuronais observadas pelas respostas luminescentes do complexo RuApy
(Universidade Federal de São Carlos, 2023-08-28)
One of the hypotheses for the cause of Alzheimer's disease is the accumulation of amyloid-beta peptide (Aβ) aggregates in the brain that lead to severe synaptic and cognitive dysfunctions resulting in neurodegenerative ...
Catalisadores baseados em nitretos de carbono grafíticos e metais de transição: síntese e aplicações
(Universidade Federal de São Carlos, 2022-03-24)
Carbon nitrides are polymeric compounds with a C3N4 stoichiometric ratio and formed by sp2 nitrogen bonds. Most of the works in the literature uses polymeric carbon nitride as a catalyst for application in organic reactions, ...
Especiação de arsênio em água e tecido de peixe empregando extração em fase sólida (SPE) e espectrometria de emissão óptica com plasma acoplado indutivamente (ICP OES)
(Universidade Federal de São Carlos, 2023-02-28)
The adverse effects caused by potentially toxic elements on the environment and human health vary according to the elements’ species, which differ in terms of toxicity. Arsenic (As) exposure is a global public health ...
Desenvolvimento e modificação a plasma de materiais a base de poli(ácido lático)/α-Ag2WO4 com potencial ação antimicrobiana
(Universidade Federal de São Carlos, 2022-01-28)
Recently, the world has been facing several microbial infections that have caused great losses and fatalities. In this scenario, the development of new materials that can be used to fight these potentially pathogenic ...
Metabolismo de daidzeína e genisteína por Spodoptera frugiperda
(Universidade Federal de São Carlos, 2021-09-20)
DAIDZEIN AND GENISTEIN METABOLISM BY Spodoptera frugiperda. As
sessile organisms, plants cannot escape the many herbivore attacks that occur
throughout their development, and rely on alternative strategies to reduce ...
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 ...
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, ...
Síntese e caracterização de catalisadores a base de Au e Cu e suas aplicações na desidrogenação do 5- hidroximetilfurfural
(Universidade Federal de São Carlos, 2021-11-30)
Dependence on oil as a source of fuel and raw material to produce chemical products opens space for the development of catalytic systems aimed at the use of biomass. In this sense, this work aims to develop a new route to ...
