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., ...
Filmes finos de LaNiO3 depositados sobre substratos monocristalinos pelo método dos precursores poliméricos.
(Universidade Federal de São Carlos, 2004-08-06)
This work reports a systematic study on the deposition and characterization of LaNiO3 thin
films. This material is a ceramic conductor and presents a near metallic behavior, and is interesting for capacitor electrodes ...
