Aspectos estruturais de compostos de Mn(II) com a lausona ou lapachol
(Universidade Federal de São Carlos, 2023-02-27)
Neste trabalho foram sintetizados complexos de manganês(II) contendo ligantes N,N-heterocíclicos (1,10-fenantrolina e 2,2’-bipiridina) e as naftoquinonas 2-hidroxi-3-(3-metil-2-butenil)-1,4-naftoquinona (lapachol) e ...
Desenvolvimento e aplicação do software HERisk para avaliação espaço-temporal de riscos: estudo de caso do rio Monjolinho e suas águas tratadas com membranas de matriz mistas
(Universidade Federal de São Carlos, 2023-03-27)
This project proposes to develop new software for the spatio-temporal assessment of radiological, ecological, and human health risks, in addition to new mixed matrix membranes (MMMs) based on polyethersulfone (PES) and ...
Reações redox catalisadas por complexos de cobre derivados de bases de Schiff: impactos do estado de oxidação e do ligante.
(Universidade Federal de São Carlos, 2023-08-31)
In this work, two series of Cu2+ complexes with Schiff base ligands derived from the amino acid L-Proline were synthesized and characterized, which are tridentate N,N,O (series 1) and tetradentate N,N,N,O (series 2). The ...
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 ...
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. ...
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, ...
