“…It was expected that particles pyrolyzed from the MnA precursor would have a rounded shape with uneven surfaces. The hollow structure of some particles was attributed to surface precipitation of the MnA precursor during SP [13]. A similar particle morphology can be found in the ZnO-added equivalent.…”

“…According to our previous thermogravimetry data, the precursor MnA, when heated at a temperature higher than 400 1C, decomposes into Mn-oxide [13,14]. Therefore, in this study, the reaction temperature was set at 500 1C for the formation of the ZnO-added SP500 powder.…”

Mesoporous bioactive glasses (MBGs) have become important bone implant materials because of their high specific surface area resulting in high bioactivity. Doping MBGs with Ag removes one of the remaining challenges to their applications, namely their lack of intrinsic antibacterial properties. In present work we demonstrate that Ag-doped MBGs can be prepared in one-step spray pyrolysis (SP) process. The SP preparation method offers the advantages of short processing times and continuous production over the sol-gel method previously used to prepare MBGs. Using scanning electron microscopy, transmission electron microscopy, and selected area electron diffraction we demonstrate that the synthesized MBG particles have amorphous structure with nanocrystalline Ag inclusions. The scanning transmission electron microscopy-X-ray energy dispersive spectrometry of cross-sectional samples shows that the distribution of the Ag dopant nanoparticles within MBGs can be controlled by using the appropriate formulation of the precursors. The distribution of the Ag dopant nanoparticles within the MBG particles was found to affect their surface areas, bioactivities and antibacterial properties. Based on the observations, we propose a mechanism describing MBG particle formation and controlling dopant distribution.

In the present investigation, the synthesis of zinc oxide (ZnO) and Mn‐doped ZnO thin film electrodes is reported for energy storage applications through spray pyrolysis technique. As‐prepared thin films are characterized by X‐ray diffraction (XRD) and scanning electron microscopy (SEM) techniques for the crystal structural and morphological analysis, respectively. The XRD pattern shows substitution of Mn2+ in ion might have substituted Zn site without changing the hexagonal structure. The micrograph of pure ZnO thin films shows that the grains are agglomerated. The Mn‐doped ZnO thin film micrographs shows the spherical type morphology. The electrochemical study is carried for various concentrations of KOH electrolyte. The maximum specific capacitance of pristine ZnO and 5% Mn/ZnO is optimized at 3 M KOH electrolyte concentration. The pristine ZnO and M5Z electrode are exhibited 151 and 360 F g−1 maximum specific capacitance, respectively.
