O processo sol-gel: uma visão físico-química
(Soc Brasileira Quimica, 2014)
Zirconia foams prepared by integration of the sol-gel method and dual soft template techniques
(Elsevier B.V., 2008-11-01)
This paper presents a new method to produce basic zirconium sulfate foams showing hierarchic porosity, based on a dual pores templating process by oil drops and gas bubbles dispersed into a hydrosol, followed by its fast ...

Textured macro- and mesoporous alumina samples designed in the presence of different surfactant types
(Springer, 2014-07-01)
This work presents a method that enables the synthesis of porous alumina in the presence of different types of surfactant. The method is based on a sol-gel transition, using surfactants and droplets of a nonpolar phase as ...
Formation of TiO2 ceramic foams from the integration of the sol-gel method with surfactants assembly and emulsion
(Springer, 2012-08-01)
A general and potentially easy method for synthesizing TiO2 ceramic foams presenting hierarchical architecture of meso and macropores is presented here. The ceramics foaming method is based on the integration of the sol-gel ...

NiTiO3 nanoparticles encapsulated with SiO2 prepared by sol-gel method
(Springer, 2008-02-01)
NiTiO3 (NTO) nanoparticles encapsulated with SiO2 were prepared by the sol-gel method resulting on core-shell structure. Changes on isoelectric point as a function of silica were evaluated by means of zeta potential. The ...
