Transporte de vapor de água e sorção de CO2 em filmes de polisulfona: efeito das variáveis de processamento e envelhecimento físico.
(Universidade Federal de São Carlos, 2004-08-31)
Water vapor transport properties and CO2 sorption were studied for bisphenol A Polysulfone films, PSF, prepared with different thickness via solvent casting and a compression molding. From the measurements of water vapor ...
Síntese e caracterização a nível nanométrico da fase Li2(M) Ti308, M=Zn, Co e Ni pelo método Pechini.
(Universidade Federal de São Carlos, 2004-06-25)
The present work describes the preparation and characterization of the spinel phases Li2ZnTi3O8, Li2CoTi3O8 and Li2NiTi3O8 synthesized by the polymeric precursor method. Polycrystalline ceramic powders of high quality ...
Estudo de estruturas, interações e reconhecimento molecular em carboidratos utilizando simulação computacional.
(Universidade Federal de São Carlos, 2004-05-11)
In this work, computer simulation methods were applied to investigate glucose-derived carbohydrates in solution at atomistic resolution. The carbohydrates considered were: trehalose and cyclodextrins. The disaccharide ...
Dióxido de estanho nanoestruturado dopado com terras raras como catalisador e sensor de gases.
(Universidade Federal de São Carlos, 2004-02-10)
This work presents and discusses results of the effects of doping on rare earth-doped nanosize SnO2, obtained using the polymeric precursor method and prepared at different annealing temperatures. Only the cassiterite phase ...
