Manipulação de spin em diodos de tunelamento ressonante não-magnéticos tipo-n
(Universidade Federal de São Carlos, 2010-04-01)
The aim of this work was to study the spin effects in non-magnetic asymmetric n-type resonant tunneling diodes (RTD). For this purpose, we have used transport and polarization resolved magneto-photoluminescence measurement ...
Influência do empacotamento cristalino nas conformações de N,N -bis(piridina-n-ilmetil) etanodiamidas e tioamidas análogas (n= 2, 3, 4)
(Universidade Federal de São Carlos, 2010-07-30)
The rational development of crystal structures requires consistent and directional formation of its synthons to control the supramolecular arrangement. Hydrogen bonds between atoms with high electronegativity (OH O and ...
Nanocristais de TiO2 : relação entre parâmetros morfológicos, estruturais e fotocatálise
(Universidade Federal de São Carlos, 2010-02-26)
In this work, morphologically different TiO2 nanocrystals were synthesized through the OPM method with the objective of performing a comparative study related to photoactivity. Morphological characterization was performed ...
Definição de rotas para coleta porta-a-porta de óleo residual de fritura visando o reuso
(Universidade Federal de São Carlos, 2010-12-15)
The collection of solid waste generated in urban areas is a growing concern for governments, health professionals and environmentalists. Among these concerns is the disposal of vegetable oil used in homes, which requires ...
Sobre o gênus de G-espaços e teoremas de coincidências
(Universidade Federal de São Carlos, 2010-07-06)
Let G be a finite group acting freely in a Hausdorff paracompact topological space X and let Y be a k-dimensional metrizable space (or k-dimensional CW-complex). In this work, by using the genus of X; gen(X;G), we prove ...
Processamento sol-gel de pós bioativos vítreos e cristalinos
(Universidade Federal de São Carlos, 2010-03-19)
In recent years, the sol-gel process has been increasingly used in the preparation of glasses and glass-ceramics with biomedical applications. Although the precursors used in this synthesis methodology are a very important ...
Análise da superfície de porcelanatos polidos por meio de microscopia de força atômica
(Universidade Federal de São Carlos, 2010-05-24)
The porcelain stoneware tile is a ceramic product that has presented a great increase on production, since it had excellent technical properties and raised aesthetic performance. To improve its aesthetic characteristics, ...
Estratégias de cultivo para a produção de polissacarídeo capsular por Haemophilus influenzae tipo b e determinação de parâmetros de qualidade para o produto
(Universidade Federal de São Carlos, 2010-08-27)
Haemophilus influenzae type b (Hib) is a Gram negative bacterium responsible for causing meningitis worldwide. The capsular polysaccharide b, a polymer composed by repeating units of ribosyl-ribitol phosphate (PRP), is the ...
Regressão de dados binários : distribuição Weibull
(Universidade Federal de São Carlos, 2010-03-12)
In this work a new class of models for binary data based on Weibull distribution is introduced. A review is made of the most known linkage functions. This class of models has as special case the complementary log-log model ...
