Multicomponent approach to silica-grafted peptide catalysts : A 3 D continuous-flow organocatalytic system with on-line monitoring of conversion and stereo-selectivity
(Universidade Federal de São Carlos, 2014-11-28)
The derivatization of organocatalysts with functional appendages suitable to anchor onto solid supports is usually achieved by stepwise syntheses. As an alternative to such a strategy, this work describes a one-pot approach ...
Determinação de arsênio total e inorgânico em sucos de frutas e arroz por ICP-MS
(Universidade Federal de São Carlos, 2016-07-07)
Analytical procedures using inductively coupled plasma mass spectrometry (ICP-MS) for the determination of total As in rice samples and fruit juices and inorganic As in rice samples were developed. A microwave-assisted ...

The following work describes the comparative study of the variation between chemical profiles of plants of the Cyperus rotundus species – where one was collected at Vale S.A.’s dumping ground in Canaã dos Carajás city, ...
Compostos carbonílicos heterobimetálicos de Ru(II)/Fe(II) : propriedades citotóxicas e estudo da interação com BSA e DNA
(Universidade Federal de São Carlos, 2016-03-30)
Ruthenium and iron-based drugs are an option for the development of improved chemotherapeutic agents for cancer treatment with lower toxicity. Thereby, this work present the in vitro cytotoxic activity and in vitro interaction ...
Abordagens sintéticas para a funcionalização de novas porfirinas
(Universidade Federal de São Carlos, 2016-09-30)
Herein, we optimized some conditions in the synthesis of a β-octasubstitued porphyrin with electron withdrawing groups (1). This system was used to study the bromination of the meso position aiming at subsequent ...
Determinação de metais por técnicas espectroanalíticas em amostras de carne e sangue de bovinos submetidos à dieta com adição de erva-mate (Ilex paraguariensis, St. Hilaire)
(Universidade Federal de São Carlos, 2016-05-23)
Given the importance of quality in the bovine meat and its relationship with the diet submitted to animals, this master dissertation has the proposition to evaluate the Ca, Cu, Fe, K, Mg, and Zn concentrations changes in ...
Catalisadores de MgO-SiO2 : efeito dos promotores CaO e SrO na conversão de etanol
(Universidade Federal de São Carlos, 2015-05-22)
The replacement of chemical products by renewable raw materials is an important factor for the emission control of CO2. Consequently, there is a great commercial interest in the conversion of ethanol into 1,3-butadiene. ...
