“…6, black trace) responsible for Si-OH stretching and hydrogen bonds of molecular water. Furthermore, absence of peak at 798 cm À1 and appearance of new moderate peak at 1350 cm À1 indicates that Ag moieties are successfully embedded on the surface of SiO 2 NPs [18,35,36]. On the other hand, Ag-SiO 2 -MBNPs (Fig.…”

Spray pyrolysis is a promising aerosol process to produce "designer particles" of precisely controlled morphology with decorations on surfaces or inside particles. Need of precise control of properties has sparked researches on aerosol process that may replace conventional processes such as solid state reaction process or liquid precipitation method. However, productivity is the biggest obstacle in the development of a commercial scale process because the aerosol process is essentially operated at low particle concentration compared to liquid phase processes. In this review, by reviewing publications for the last 10 years we discuss how researchers on spray pyrolysis circumvent this inherent limitation of the aerosol process. First, the process of particle design by spray pyrolysis is introduced. Some key criteria are explained for selecting each component of spray pyrolysis: precursor, additive, carrier gas, heat source, and reactor type. Second, key contributions of major groups in Korea, Japan, Europe, and America are described. Third, some of named processes to overcome productivity of spray aerosol process are introduced. Fourth, applications of spray pyrolysis to materials related to alternative energy, environmental cleaning, information processing and display, and biomaterials are considered. Finally, future prospects of spray pyrolysis are discussed along with current standing issues for further progress of spray pyrolysis.

“…These chemical group vibrations are also present in sample S 3 (Figure 1‐1b), but a very strong peak at 943 cm −1 assigned to Si–OH stretching can also be identified. The band at 1 593 cm −1 is attributed to the bending vibration of the H–O–H bond originating from chemisorbed water 27. These features indicate the presence of silanol groups with hydrophilic characteristics that are present when silver is added to the system.…”

“…Consequently only the spectra of the systems without silver and those with higher Ag content for the S and H systems and with intermediate Ag concentration for P system are present in Figure 1. The silver free thin SiO 2 film (Figure 1‐1a) has two distinct peaks at 1 012 and 1 094 cm −1 both corresponding to the Si–O–Si asymmetric stretching vibration, and show an absorption band at 806 cm −1 for Si–O–Si symmetric stretching 27. These chemical group vibrations are also present in sample S 3 (Figure 1‐1b), but a very strong peak at 943 cm −1 assigned to Si–OH stretching can also be identified.…”

Thin nanocomposite hybrid films were deposited by r.f. magnetron sputtering. These were composed of of SiO2, poly(propylene) (PP) and SiO2/PP, with Ag contents varying from 0 to 30 at.‐%. The influence of metal concentration on the properties of the deposited surfaces was evaluated. The chemical composition, chemical structure, morphology, dynamic wettability behavior, and microstructure were studied. The overall properties of the inorganic/organic system are more influenced by those of the ceramic fraction than by the polymeric one. The hysteresis of the contact angle shows that all the surfaces interact with water and that the presence of the metallic element increases reactivity in an aqueous medium. These results show promising applications in the biomedical field particularly in those that use silicon as a biomaterial for implants.
