Complexos mono, bi e trinucleares de metais de transição com bases de Schiff tridentadas tipo ONN e tetradentadas do tipo ONNO : síntese, caracterização e estudos como catalisadores na oxidação de catecois
(Universidade Federal de São Carlos, 2015-09-11)
Salen-type complexes are an important class of
coordination compounds, which have been used to catalyze a wide variety of
reactions in various homogeneous and heterogeneous systems. Complexes of
transition metals are ...
Avaliação de polímeros impressos para pré- concentração/extração de Se, U e Cd
(Universidade Federal de São Carlos, 2015-06-18)
This thesis describes the development of imprinted polymers for preconcentration of Se, Cd and U. The relevant factors to the FIA system and preconcentration were optimized by Doehlert matrix. Chapter I describes an ...

(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 ...
