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 ...
Transporte e morfologia de esquemas de tintas epóxi poliamina equivalentes à base de solvente e água.
(Universidade Federal de São Carlos, 2003-07-21)
In the present work, anticorrosive properties of solvent borne and water based epoxy polyamine coatings were studied comparatively. First these studies were performed for the individual layers of these coatings, i.e., ...
Estudo de pós cerâmicos de PbTiO3 utilizando-se o método dos precursores poliméricos.
(Universidade Federal de São Carlos, 2000-11-30)
THE STUDY OF PbTiO3 (PT) CERAMIC POWDERS USING THE POLYMERIC PRECURSOR METHOD was started by the preparation of a precursor solution of metallic cations. Citric acid was used as quelation agent and ethylene glycol as ...
