Complexos fosfínicos de Pd(II) com produtos naturais: síntese, caracterização, avaliação da citotoxicidade e interação com biomoléculas
(Universidade Federal de São Carlos, 2023-11-29)
This thesis details the synthesis, characterization and evaluation of antitumor activity of twelve monocationic PdII/phosphine complexes featuring ligands derived from products natural. The complexes were categorized in ...
Impacto das nanopartículas de Sílica na transição de polímeros termossensíveis usados na administração controlada de medicamentos
(Universidade Federal de São Carlos, 2024-01-26)
Conventional systemic drug delivery methods have shown reduced effectiveness compared to localized release systems. Therefore, thermosensitive nanocomposites were synthesized using poly(N-vinylcaprolactam) (PNVCL) and ...
Oxidação fotoeletroquímica de metanol, etileno glicol e glicerol em CdS, BiVO4 e BiVO4:Zr-Mo:Pt
(Universidade Federal de São Carlos, 2023-12-15)
The photoelectrochemical production of hydrogen (H2) from the water splitting reaction in photoelectrochemical cells is a promising alternative for the production of clean and sustainable energy. However, this process still ...
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 ...
Asymmetric induction on isocyanide-based transformations: development of stereoselective Ugi-type reactions
(Universidade Federal de São Carlos, 2023-05-26)
The design of new synthetic transformations that rapidly allow construction of structurally complex molecules from simple starting materials under both concepts of diversity and function-oriented syntheses is extremely ...
Influência de complexos polipiridínicos de Ru(II) no processo de agregação do peptídeo beta amiloide
(Universidade Federal de São Carlos, 2023-02-27)
Most neurodegenerative diseases are associated with abnormal protein aggregation. Amyloid proteins are highly prone to aggregation and, consequently, accumulate in the brain, disrupting synapses and causing neurotoxicity. ...
Desenvolvimento de métodos de pré-concentração para a determinação de elementos traço e especiação de cromo e arsênio em amostras agrícolas
(Universidade Federal de São Carlos, 2021-10-27)
Agricultural sustainable production is indispensable to meet the growing demand for food and nutritional control. The risk assessment associated with contamination by toxic elements in agricultural and aquaculture matrices ...
Obtenção e aplicação de fotoanodos baseados em TiO2 com adição de nitretos de carbono polimérico do tipo poli(heptazina imida)
(Universidade Federal de São Carlos, 2022-07-01)
In this work, poly(heptazine imide) carbon nitrides containing metals single atom in the ionic form were evaluated alone and in the combination with TiO2. Initially, a percentage of 2.5% of the nickel-containing material ...
Polipropileno modificado com semicondutores a base de prata: compósitos com alta potencialidade contra SARS-CoV-2 e outros patógenos
(Universidade Federal de São Carlos, 2023-03-30)
The worldwide outbreak of the coronavirus (COVID-19) pandemic and other
emerging infections is difficult and sometimes impossible to treat, making them
one of the major public health issues of recent times. It is ...
Desenvolvimento de um magneto-imunoensaio microfluídico com detecção eletroquímica para diagnóstico de hanseníase
(Universidade Federal de São Carlos, 2023-03-23)
Leprosy is an infectious disease caused by the bacteria Mycobacterium leprae and its diagnosis is mostly performed by clinical examination. Thus, in this work, two magnetoimmunoassays were developed for the serological ...
