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 ...
Síntese assimétrica dos componentes do feromônio sexual da lagarta-parda, Thyrinteina arnobia (Lepidoptera: Geometridae)
(Universidade Federal de São Carlos, 2013-01-31)
The pheromones play an important role in chemical communication between alive organisms. They can be used in agriculture to pest control. The brown-caterpillar, Thyrinteina arnobia, is considered in Brazil a major pest of ...
Avaliação de novas arquiteturas de carbono para o desenvolvimento de sensores eletroquímicos para a determinação de espécies de interesse em diferentes matrizes de amostras
(Universidade Federal de São Carlos, 2019-03-01)
In this doctorate work the efforts were expended in the electrochemical study and electroanalytical application of electrochemical sensors based on two carbonaceous structures: diamond-like carbon (DLC) and carbon black ...
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 e estudo das propriedades fotoluminescentes dos pós de CaTiO3 decorados com α-Ag2WO4
(Universidade Federal de São Carlos, 2016-02-24)
The CaTiO3 (CT) and α-
Ag2WO4 (AW) are known to have photoluminescent properties, which is favored by
the existence of a structural disorder. The combination of these two materials was
observed through decoration of ...
Avaliação do uso de múltiplas linhas para a determinação de metais por espectrometria de emissão óptica com plasma acoplado indutivamente
(Universidade Federal de São Carlos, 2010-06-11)
The aim of this thesis was the evaluation of the use of multiple lines for determination of metals by inductively coupled plasma optical emission spectrometry (ICP OES) with Littrow optical system, Echelle polychromator ...
