“…So, these can be used at very lower doses compared to conventional zinc to enhance the animal performance, immunity, reproduction, act as antimicrobial agent and reducing environmental contamination [2,6,[16][17][18][19][20][21][22][23][24][25][26][27]. Numerous techniques have been evolved for the synthesis of ZnO in nano form such as vapour-liquid-solid (VLS) [28], pulsed laser deposition [29], electro chemical deposition [30], metal vapour transport [31,32], chemical vapour deposition [33], metal organic chemical vapour deposition [34]; the hydrothermal growth approach [35], Mechano-Chemical Method [36], chemical precipitation method [37],and sol-gel method [38,39]. This work aimed to reach the best reaction's temperature for synthesis ofhigh impact zinc oxide nanoparticles.Four samples of zinc oxide nanoparticles were synthesized on different reaction's temperatures; 0 °C, 50 °C, 90 °C, and 0-RT °C via green sol-gel method.…”

T HIS study was conducted as an attempt to reach the best method to synthesis zinc oxide nanoparticles (ZnONPs) using chemical methods. ZnO nanoparticles was prepared using Sol-Gel method from zinc chloride (ZnCl 2) and sodium hydroxide (NaOH) as chemical reactors and polyethylene glycol with low molecular weight as surfactant. The effect of the different reaction's temperature on the produced ZnO nanoparticles was studied. Four samples of zinc oxide nanoparticles were prepared on different reaction's temperatures; 0 °C, 50 °C, 90 °C, and 0-RT°C (the reaction beginning at 0 °C and after that increase the temperature to reach the RT). The obtained products were examined using different techniques; X-ray Diffraction (XRD), High Resolution Scanning Electron Microscope (HRSEM), Fourier Transform Infrared (FT-IR), Ultraviolet-Visible Spectroscopy (UV-Vis), and Energy Dispersive X-ray Analysis (EDAX). The results showed that XRD, FT-IR, and EDAX confirmed the presence of ZnO nanoparticles with high purity. The UV-Vis. absorption spectrum showed an absorption band at 376nm due to ZnO nanoparticles. HRSEM showed the superiority of ZnO nanoparticles that synthesized at 50°C and the inferiority of that synthesized at 0-RT °C.

“…The formation of ZnO nanoparticle showed a peak at 3442 cm -1 and 1634 cm -1 corresponding to O-H stretching and bending vibrations of water molecules and the peaks at 1383 cm -1 corresponding to the presence of NO 3 was confirmed. A peak around 432 cm -1 corresponding to the formation of Zn-O metal oxide bond [29]. The formation of Ni-ZnO nanoparticle showed peaks at 3461 cm -1 and 1633 cm -1 corresponding to O-H stretching and bending vibrations of water molecules and the peaks at 1383 cm -1 corresponding to the presence of NO 3 was confirmed.…”

Three groups of plastic emulsion paints were formulated using three different types of pigments. TiO2 was applied in the first group of paint (T-series) as a neutral pigment. Zn3(PO4)2 and Fe2O3 were added in the two other paint groups (Z-series and F-series, respectively) as anticorrosive pigments. Styrene/butyl acrylate latex was prepared by semicontinuous seeded emulsion polymerization and used as a binder in the paint formulations. Poly (ani-co-o-toluidine) (PAOT) was introduced to the painting series as an inhibitor in proportions of 0%, 1%, 2%, 3%, and 4%. PAOT inhibitor was prepared by oxidative emulsion polymerization with an equimolar amount of aniline and o-toluidine monomers. The binder and the inhibitor were tested for their particle size and chemical structure by DLS and FTIR analysis. The properties of the paint formulations were estimated physically, mechanically, and thermally. The protection efficiency of the paint coatings on steel was estimated against corrosion using an immersion test and electrochemical measurements. The DLS curves of the binder latex and the inhibitor showed a unimodal distribution of sizes 151 nm and 42 nm, respectively. However, a mix of the two emulsions exhibited a bimodal distribution of both sizes. The potentiodynamic polarization measurements showed a decrease in the corrosion current density of TiO2 coating paint from 26.4×10-7 A/cm2 to 12.3×10-7 A/cm2 in Fe2O3 coating paint. The least corrosion current density was obtained from Zn3(PO4)2 coating paint of 7.50×10-7 A/cm2. PAOT inhibitor enhanced the protection efficiency of the paint coatings with the optimum of 3%. Zn3(PO4)2 coating paint loaded with 3% PAOT inhibitor demonstrated the highest protection efficiency of 99.96%.
