“…As with any CVD technique actual growth rates or dopant incorporation rates crucially depend on substrate temperature, precursor concentration and in case of spray pyrolysis also the solvent [11,17]. For DBTDA and SnCl 4 ·5H 2 O a 0.1M solution has been prepared using methanol or ethanol as solvent.…”

“…Spray pyrolysis could fulfil these requirements, providing films with optical and electrical properties comparable with those grown by the more expensive vacuum deposition techniques currently used. [11][12][13][14] For a long time CBrF 3 has been used as F source for CVD. However this is a greenhouse gas which has been gradually phased out from the market [15].…”

“…The reacting elements are chosen such that the undesired chemical species produced are volatile under reaction conditions. The process is highly suitable for production of nanostructured oxides (Mooney and Radding 1982;Patil 1999). Figure 2 shows a typical spraying system used in this research.…”

Prevention of asphaltene formation in reservoir rocks can result in resolving a severe long-lasting issue in petroleum production. The present research addresses the issue in the context of exploring the potential effect of nickel oxide (NiO) nanoparticles in destabilizing asphaltene deposition in porous media, in the presence of carbon dioxide. To ensure proper distribution within the system and to retain future field-scale applicability, the NiO nanoparticles were exposed to the in situ oil via injection gas stream, in which they had been uniformly dispersed using polydimethylsiloxane (PDMS). The experimental results, established under miscible CO 2 state, indicate a considerable improvement in permeability/porosity reduction of core, as well as less asphaltene accumulation in porous media and increased oil recovery factor after applying NiO nanoparticles.

“…Spray pyrolysis is of special interest due to its simplicity and versatility [19]. By air atomizing a precursor solution on a heated substrate, thin or thick films or coatings can be deposited and, by adjusting the process parameters, the microstructure can be tailored.…”

Vertical cracks are beneficial in thermal barrier coatings due to enhanced thermomechanical compliance. Accordingly, an aqueous nitrate based precursor solution was atomized on stainless steel substrates by spray pyrolysis to deposit thick crack-designed lanthanum zirconate coatings. Coatings with designed crack patterns were deposited and characterized by electron microscopy, tribology, Vickers indentation, and thermal diffusivity. The crystallization of the coatings was investigated by in situ high temperature X-ray diffraction. The green coatings crystallized from 600 °C and the pyrochlore structure was formed after heat treatment at 1000 °C. Crystalline lanthanum zirconate multilayered coatings with small crack spacing and crack opening exhibited a higher density, a higher hardness, lower thermal diffusivities, and higher thermal conductivities compared to crystalline monolayered coatings of similar thickness with large crack spacing and crack opening. The thermal diffusivity of the coatings, ~28 mm 2 /s at room temperature, was similar to the values reported for yttria-stabilized zirconia plasma sprayed coatings.
