Busca de compostos inseticidas: estudo de espécies do gênero Trichilia (Meliaceae)
(Universidade Federal de São Carlos, 2006-05-15)
This work describes the results of the search for
insecticidal compounds from the Meliaceae family. The samples assayed against
fall armyworm Spodoptera frugiperda were the hexane, methanol and
hydromethanol extracts ...

(Universidade Federal de São Carlos, 2004-06-23)
This work describes the implementation of two recent techniques in NMR - DOSY e HR-MAS
as a tool for the analysis of natural products mixture and in leaves of Citrus, respectively. The work begun with the technique DOSY, ...
Desenvolver a cidadania através da química : é possível? Um desafio a ser vencido
(Universidade Federal de São Carlos, 2003-12-17)
The present work was inspired by the High School National
Curriculum Parameters (PCNEM) as well the Schnetzler proposal of teaching
chemistry to citizenship. It is also based on the observed chemistry teaching
problems, ...
Desenvolvimento de procedimentos automáticos para determinação de etanol, glicerol e ácido tartárico em vinho empregando multicomutação em fluxo.
(Universidade Federal de São Carlos, 2004-08-18)
In the present work, flow systems for the determination of ethanol, glycerol and
tartaric acid in wine without previous sample treatment are described. The flow
system were based on multicommutation and controlled by ...
Análise em fluxo e análise in situ como estratégias de melhoramento da seqüência analítica de amostras agronômicas.
(Universidade Federal de São Carlos, 2005-04-06)
The
present work discusses the use of alternative approaches for the improvement of the
agronomic sample analytical pathway. It was focused on the elimination of the
sampling step, with the in situ soil analysis, or in the ...
Método periódico para interpretar propriedades dos materiais.
(Universidade Federal de São Carlos, 2005-03-17)
In this work was done mecanic-quantic periodic in level ab initio and
using the density functional theory (DFT) combined with the B3LYP (BECKE 1993;
LEE, et al 1998) to a series of titanates. Models periodic simulations ...

(Universidade Federal de São Carlos, 2003-10-08)
In this thesis two polymers obtained from alkyl derivatives of
thiophene, poly(3-methylthiophene) and poly(3-hexylthiophene) were studied.
The effects of preparation variables on their electrochemical properties using ...
Quantificação de metacrilatos residuais e avaliação da liberação em saliva artificial a partir de resinas acrílicas para reembasamento imediato
(Universidade Federal de São Carlos, 2008-05-21)
This work reports the development of analytical methods, using High Performance of Liquid Chromatography (HPLC), to quantify unreacted monomers from dental reline autopolimerizing acrylic resins. The quantification of these ...
Desenvolvimento de estratégias para a determinação espectrofotométrica sequencial em fluxo de Co (II) e Mn (II)
(Universidade Federal de São Carlos, 2009-07-24)
In this study a kinetic-spectrophotometric method was developed for sequential determination of Co and Mn in pharmaceutical samples. The method was based on the catalytic effect of the analytes in the oxidation reaction ...
Complexos carbonílicos de rutênio. De um gás tóxico a uma droga com potencial agente citotóxico
(Universidade Federal de São Carlos, 2007-11-27)
In this work ruthenium carbonyl complexes were synthesized and characterized which allowed an interesting spectroscopic and structural study as well as preliminary in vitro antitumor activity assays. Thus, the interests ...
