(Universidade Federal de São Carlos, 2015-02-26)
This work involves the synthesis and characterization of three new series of ruthenium complexes containing gallic acid and derivatives cinnamic acid and salicylic acid and derivatives, as these ligands exhibit interesting ...
Aplicação de métodos quimiométricos de calibração e resolução multivariada de curvas em espectroscopia Raman para Análise qualitativa e quantitativa de polimorfismo em carbamazepina, clopidogrel e ezetimiba
(Universidade Federal de São Carlos, 2015-07-31)
In this work were used chemometric tools like PLS, iPLS to perform multivariate calibration of ternary and binary mixtures of polymorphs of carbamazepine, ezetimibe and Clopidogrel. Initially were synthesized two polymorphs ...
Desenvolvimento de filmes nanocompósitos contendo purê de vegetais para aplicação como embalagem comestível
(Universidade Federal de São Carlos, 2015-03-27)
Petroleumderived packaging are neither renewable nor biodegradable. Based on it, recent studies have been focused in biopolymer-based packaging, such as in
polysaccharides (e.g., pectin and chitosan), due to their good ...

In this study, it was made the determination of nutrients (in the forms of orthophosphate,
total phosphorus, nitrogen series, total nitrogen and total dissolved carbon) and
physicochemical variables in surface waters and ...
Desenvolvimento e validação de metodologias analíticas para quantificação de mercúrio total e metilmercúrio em água utilizando a técnica de fluorescência atômica do vapor frio
(Universidade Federal de São Carlos, 2016-02-23)
In this work, we used the cold vapour atomic fluorescence spectrometer technique
for quantification of total mercury and methylmercury. The importance of quantification
of total mercury in water is associated with toxicity ...
Abordagens sintéticas visando a preparação de bacterioclorinas de alta conjugação
(Universidade Federal de São Carlos, 2016-02-12)
Bacteriochlorins are porphyrin derivatives containing two reduced
peripheral double bonds (FIGURE 1). These compounds present, as their main
properties, intense absorption bands close to the Near Infrared (NIR, 750-900
nm) ...
