NANOSTRUCTURED ZrO₂ POWDER SYNTHESIZED BY ULTRASONIC SPRAY PYROLYSIS [PDF]

Surface Review and Letters, 2007
The synthesis of nanostructured zirconia particles from aqueous colloidal dispersion of zirconia (zirconia sol) was carried out by ultrasonic spray pyrolysis method. The morphology of these nanostructured particles was characterized by scanning electron microscopy and transmission electron microscopy.

Ultrasonic spray pyrolysis of TiO2 nanoparticles

Nanostructured Materials, 1997
Synthesis of ultrafine spherical TiO2 particles was achieved by using ultrasonic spray pyrolysis and nanoparticles of TiO2 (approximate to 2.5nm) as a precursor. The size distribution and morphology of TiO2 particles obtained after ultrasonic spray pyrolysis were characterized by SEM and STM.

Ultrasonic spray pyrolysis for nanoparticles synthesis

Journal of Materials Science, 2004
This article presents new findings regarding the effects of precursor drop size and precursor concentration on product particle size and morphology in ultrasonic spray pyrolysis. Large precursor drops (diameter > 30 μm) generated by ultrasonic atomization at 120 kHz yielded particles with holes due to high solvent evaporation rate, as predicted by the ...

Magnetic and Porous Nanospheres from Ultrasonic Spray Pyrolysis

Journal of the American Chemical Society, 2005
We have used an inexpensive high-frequency ultrasound generator from a household humidifier to create a useful source for ultrasonic spray pyrolysis and produced submicrometer silica particles that are porous on the nanometer scale. By using two heated zones, we first initiate polymerization of organic monomers in the presence of silica colloid, which ...

Porous Carbon Powders Prepared by Ultrasonic Spray Pyrolysis

Journal of the American Chemical Society, 2006
New, thermally robust meso- and macroporous carbon powders were prepared by ultrasonic spray pyrolysis (USP) of aqueous solutions using an inexpensive high-frequency ultrasound generator from a household humidifier. We choose our molecular precursors rationally, so that the expected decomposition pathways produce only remnant carbon atoms. Specifically,

Air-assisted ultrasonic spray pyrolysis for nanoparticles synthesis

SPIE Proceedings, 2002
This paper presents new findings regarding the effects of precursor drop size and concentration on product particle size and morphology in ultrasonic spray pyrolysis of zirconium hydroxyl acetate solutions. Large precursor drops (diameter >30μm) generated by ultrasonic atomization at 120kHz yielded particles with holes.

Hydroxyapatite coatings by pulsed ultrasonic spray pyrolysis

Ceramics International, 2008
Hydroxyapatite coatings on 316L stainless steel substrates were prepared using ultrasonic spray deposition with substrate temperature kept at 300 °C. Two spray patterns, continuous and pulsed (intermittent), were used coupled with precisely control of substrate movement.

Nanostructured Carbons Prepared by Ultrasonic Spray Pyrolysis

Chemistry of Materials, 2010
Porous carbon powders were prepared by ultrasonic spray pyrolysis of solutions of sucrose and sodium carbonate or bicarbonate. The decomposition of the carbonate salt evolves gases that create porosity in the carbon material without sacrificial templating agents. Microporous particles with a macroporous or hollow interior have been produced.

Anatase thin films by ultrasonic spray pyrolysis

Journal of Analytical and Applied Pyrolysis, 2010
Abstract TiO 2 thin films were deposited on glass slides using ultrasonic spray pyrolysis at 400 °C for times in the range 30–120 min. All of the films consisted of fully dense polycrystalline anatase. The first-order growth kinetics were determined to be 11 nm/min, which is similar to those of other thin-film fabrication methods.

Cytotoxicity of Gold Nanoparticles Prepared by Ultrasonic Spray Pyrolysis

Journal of Biomaterials Applications, 2010
The aim of this work was to study the cytotoxicity of different fractions of gold nanoparticles prepared by ultrasonic spray pyrolysis from gold scrap. The target cells were rat thymocytes, as a type of nonproliferating cells, and L929 mouse fibroblasts, as a type of continuous proliferating cells.
