(Universidade Federal de São Carlos, 2007-05-03)
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 ...
Desenvolvimento de nanocamadas e nanocristais de Óxido de Zircônio aplicados a catálise
(Universidade Federal de São Carlos, 2007-09-14)
