The ZnO and ZnMgO nanostructures were grown on silicon substrates at different temperatures, using gold metal as a catalyst in the presence of argon as a carrier gas in a conventional tube furnace.
The effects of the substrate temperatures, gold catalyst, and source material preparation on the morphological and optical properties of the nanostructures were investigated.
Si substrates were c
phases, i.e., hexagonal ZnO (JCPDS 36-1451), hexagonal Zn (JCPDS 04-0831), cubic Au (JCPDS 04-0784), and orthorhombic Au2O3 (JCPDS 43-1039). The ZnO-associated peaks are attributed to the ZnO nanowires. In addition, we surmise that the excessive Zn in the vapor is adsorbed on the solid surface, resulting in Zn peaks [12]. The inset of Fig. 3b shows a selected SEM image of the AZO coated ZnO nanow
carriers as pallets: their function is to carry other products and they can serve this purpose several times. Summarizing, distribution returns comprehend:
• product recalls;
• commercial returns (e.g. unsold products, wrong/damaged deliveries);
• stock adjustments;
• functional returns;

phase shift of the advertising audience to remember your ad is the five work. For this reason, while exposing companies to pay huge costs for advertising, but you can see impressions relatively small compared to the cost of advertising effectiveness can be halved. Also, the advertising model, this duplication appeared to weaken the company's brand image of credibility is down.
