Modeling of nanostructural design of ultrafine mullite powder particles obtained by ultrasonic spray pyrolysis

Calcium Hydroxyapatite Thin Films on Titanium Substrates Prepared by Ultrasonic Spray Pyrolysis

“…The islands were of irregular shapes, and thus were formed by the coalescence of grains, whereby the bigger grains grew on the account of the disappearance of the smaller ones. By using calculations for average droplet size (over 100 nm, corresponding to almost every real case) presented in the previous references, [30][31][32][33][34] it was shown that all the droplets were of diameters much larger than the dimensions of the nuclei in embryo stage. Due to this fact, the classical initial step of coating forming was skipped and the initial stage of the deposition process was coalescence.…”

“…The deposition of calcium hydroxyapatite on metal substrates by using ultrasonic spray pyrolysis can be considered as one of the methods for overcoming the drawbacks of plasma techniques, related to the problems of the poor control of the stoichiometry and phase composition of the deposited materials. [28][29][30][31][32][33][34][35] Not only homogenous composition of coatings, but also a uniform distribution of the deposit along a metallic substrate might be achieved by using ultrasonic spray pyrolysis.…”

Effect of Carbon Modification on the Electrical, Structural, and Optical Properties ofTiO2Electrodes and Their Performance in Labscale Dye-Sensitized Solar Cells

“…In order to extend the absorption region of TiO 2 to use the majority of the sunlight of the solar spectrum, doping of titanium dioxide with nonmetal, transition metals, and composite transition metal oxide has been employed [30][31][32][33][34][35]. Doping of TiO 2 inhibits recombination of photogenerated electrons and holes by increasing the charge separation and, therefore, enhances the efficiency of photon generation [30].…”

CuInS2 films deposited by aerosol-assisted chemical vapor deposition using ternary single-source precursors

“…It was believed that the nanoparticles were created over the hot substrate by pyrolysis of nano-drops generated from the aerosol that continued carrying the ultrasonic excitation and further broke into a number of substructures. 19 Using the previously reported model, 19 the size of nanoparticles was estimated to be about 100 nm, assuming an average aerosol droplet diameter of 13 µm, as determined by theoretical prediction. 20,21 Clusters could be formed by the coagulation of nanoparticles before landing on the growth surface.…”
