Combining the spray pyrolysis and the sol-gel techniques (spray-gel) gives the possibility to produce very rough and highly diffuse films, under appropriate conditions. This technique is suitable for producing multifunctional ...

Boehmite (gamma-AlOOH) synthesis have been investigated using a spray pyrolysis (SP) device starting from a stable sol of Al-tri-sec-butoxide peptized by nitric acid. Free spherical particles from 100 to 500 nm have been ...

AISI 316L stainless steel is mainly used in biomedical applications, even though it suffers localized corrosion. Its protection can be achieved creating a barrier for ions migration. This paper presents the synthesis and ...

In this study, the release rate of cyanocobalamin from different sol-gel spray-dried silica microspheres formulations was investigated. The drug was incorporated into a sol phase of a silica precursor, tetraethyl orthosilicate ...

We present a comparison between zinc oxide films made by sol-gel dip-coating and spray-pyrolysis to be employed in optoelectronic applications. Grain size, shape, roughness, thickness, band gap, composition, crystalline ...

Chemical Spray Pyrolysis Technique and a combination of sol-gel and spray pyrolysis techniques have been used in order to monitor the morphology of metal-oxide-based thin films to be used as functional materials. We can ...

Se obtuvo una solución precursora del ZnO por el método sol-gel, después del envejecimiento de la misma se pulverizó este precursor sobre un sustrato para producir un recubrimiento delgado de ZnO; esta técnica se conoce ...

Highly porous mixed WO3–SnO2 films have been prepared from an aqueous solution of SnCl4.5H2O and polytungsten gel with a molar ratio of Sn/W from 0 to 1. These solutions were sprayed on to alumina substrates at 220 ºC. The ...
