Degradação eletroquímica dos herbicidas tebutiuron e picloram usando anodo de diamante dopado com boro ou de dióxido de chumbo em um reator filtro-prensa
(Universidade Federal de São Carlos, 2015-10-23)
The electrochemical degradation of the herbicides tebuthiuron (TBT) and picloram (PCL) was carried out in a filter-press reactor using boron-doped diamond (BDD) or lead dioxide as anode, investigating the effect of current ...
Produção e caracterização de mantas de nanofibras poliméricas eletrofiadas contendo proantocianidinas e sua potencial aplicação no tratamento de lesões cutâneas
(Universidade Federal de São Carlos, 2018-11-23)
The development of novel biodegradable and biocompatible nanofibrous membranes are highly desirable for biomedical applications, including drug delivery and wound dressing. Thus, the present thesis focused on the development ...
Análise da sazonalidade e regionalidade em suco de laranja natural por ressonância magnética nuclear (RMN) e quimiometria
(Universidade Federal de São Carlos, 2017-10-27)
The Nuclear Magnetic Resonance (NMR) has been become increasingly helpful as an analytical tool to assess the food quality, specially to highlight fruit juice in the last few years. In this context, NMR has presented ...
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 ...
Emprego de imagens hiperspectrais e espectrometria de emissão em plasma introduzido por laser na análise direta de amostras de lixo eletrônico
(Universidade Federal de São Carlos, 2015-02-27)
In this study, laser induced breakdown spectroscopy was combined with chemometric
tools to study the chemical composition of WEEE discarded. For this, three
samples of printed circuit board were chosen for analysis: PCBs ...
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 ...
Desenvolvimento de um imunossensor descartável acoplado a um sistema microfluídico para determinação de um biomarcador tumoral
(Universidade Federal de São Carlos, 2016-02-19)
Breast cancer is the most common type of cancer among women and results in 70% of cases of estrogen receptor alpha (ERα)
overexpression, a tumor biomarker. In the present study we developed a
sensitive and low cost ...
