Desenvolvimento de procedimentos para a síntese e caracterização de catalisadores e de biodiesel
(Universidade Federal de São Carlos, 2017-06-08)
ABO3 basic catalysts were synthesized by the nitrate-b-alanine solution combustion method. The catalysts powders were produced by self-combustion in times up to 5 min, presenting high crystallinity and single-phase, without ...
Síntese de WO3 e de heteroestruturas WO3/TiO2 pelo método de oxidação por peróxido e avaliação do potencial como fotocatalisadores
(Universidade Federal de São Carlos, 2015-12-08)
The use of semiconductors for environmental applications and solar photoconversion has been widely explored recently. Due the intensive researches on renewable energy such as the photoelectrochemical H2 evolution from water ...
Flow Chemistry: From assembly to the application
(Universidade Federal de São Carlos, 2018-12-17)
Over the centuries, chemical reactions have been carried out in the same way in standardized glassware. On the other hand, continuous flow reactions are gaining interest regularly and demand for the related hardware toolkit ...
Efeito da promoção de turbulência na hidrodinâmica de um reator tipo filtro-prensa e na degradação eletroquímica do bisfenol S
(Universidade Federal de São Carlos, 2019-06-28)
The kinetics of many electrochemical processes is limited by mass transport, especially at low concentrations of the reactant. The use of turbulence promoters in parallel-plate reactors increases the hydrodynamic turbulence ...
Especiação química de As e Cd por HPLC-ICP-MS em forrageira Brachiaria brizantha Stapf. cv. Marandu cultivada em solo previamente contaminado
(Universidade Federal de São Carlos, 2014-03-21)
Recent research and advances in analytical chemistry show that the total content determination of an element, although it is essential, is limited since it is not sufficient to provide information about the bioavailability ...
Investigação das propriedades ópticas e fotocatalíticas de materiais a base de fosfato de prata
(Universidade Federal de São Carlos, 2019-08-05)
The semiconductor-based photocatalytic degradation of synthetic dyes has been considered a promising approach in wastewater treatment. The main objective in this doctoral thesis was the investigation on structural, ...
Complexos de rutênio(II) com potenciais atividades antitumorais: síntese, caracterização e ensaios biológicos
(Universidade Federal de São Carlos, 2013-12-13)
In this thesis phosphinic ruthenium complexes coordinated to ligands of biological interest: folic acid, 6-mercaptopurine, 2-mercaptopyridine and 8-aminoquinoline, dpqQX, dppz and dpq (dipyridophenazine and derivatives) ...
Produção e caracterizações de superfícies antimicrobianas e bioativas sobre titânio
(Universidade Federal de São Carlos, 2019-07-19)
Titanium (Ti), being biocompatible and presenting chemical stability and good mechanical properties, is the most used material for manufacturing dental implants. However, implants present a high number of failures mainly ...
