The hydrothermal process is considered as one of the simplest and cheapest methods applied to prepare zinc oxide nanorods (ZnO-NRs) to be arranged on glass substrates. Each glass substrate was pre-coated by ZnO seed layer. The grown nanostructures were annealed in air at temperatures of 200, 250 and 400 °C. The effect of annealing process on structural, optical and morphological properties has been studied. The X-ray diffraction (XRD) tests confirmed that all synthesized samples are polycrystalline structures that possess hexagonal shapes and preferable orientation plane of (002), along with c-axis coordination which is also evident from FE-SEM image. The intensity of (002) peak was most prominent at 250 °C. Due to the increase in crystals size with annealing temperature at 250 °C, the full width at half maximum (FWHM) has been decreased. The energy dispersive spectroscopy test (EDS) showed that the Zn:O atomic ratio for all samples was nearly stoichiometric. The atomic force microscopy (AFM) image show that the root mean square (RMS) decreases when the temperature increases up to 400 °C. The optical transparency and band gap of (ZnO-NRs) decreased with the increase of annealing temperature.

“…The diffraction peaks are situated at 2u = 25.341°, 37.860°, 48.109°, 53.950°and 55.120°, which match to the typical diffraction peaks of anatase TiO 2 at positions (1,0,1), (0,0,4), (2,0,0), (1,0,5) and (2,1,1), respectively (JCPDS: 21-1272) (Li et al, 2008). The diffraction peak location (Abed et al, 2019). After 10 h of DBDP-assisted ball milling, the average grain size is reduced to 54.1 nm, the lattice distortion increases by 36% and the refinement impact is noticeable.…”

“…The diffraction peak location of TiO 2 did not change before and after alteration, showing that the crystal phase composition of TiO 2 NPs remained anatase TiO 2 after modification. The grain refinement and lattice distortion are calculated according to Williamson–Hall relation theorem (Abed et al , 2019). After 10 h of DBDP-assisted ball milling, the average grain size is reduced to 54.1 nm, the lattice distortion increases by 36% and the refinement impact is noticeable.…”

Purpose The purpose of this paper is to enhance the characteristics of TiO2 nanoparticles (NPs). Because these NPs stick together easily and are difficult to distribute evenly, they cannot be used extensively in lubricating oils. Altering TiO2 was recommended as an alternate way for making NPs simpler to disperse. Design/methodology/approach Through dielectric barrier discharge plasma (DBDP)-assisted ball mill diagnostics and modeling of molecular dynamics, TiO2@PEG-400 NPs were produced using the DBDP-assisted ball mill. The NPs’ microstructure was examined using FESEM, TEM, XRD, FT-IR and TG-DSC. Using the CFT-1 reciprocating friction tester, the tribological properties of TiO2@PEG-400 NPs as base oil additives were studied. EDS and XPS were used to examine the surface wear of the friction pair. Findings Tribological properties of the modified NPs are vastly superior to those of the original NPs, and the lipophilicity value of TiO2 NPs was improved by 200%. It was determined through tribological testing that TiO2@PEG-400’s exceptional performance might be attributable to a chemical reaction film made up of TiO2, Fe2O3, iron oxide and other organic chemicals. Originality/value This work describes an approach for preventing the aggregation of TiO2 NPs by coating their surface with PEG-400. In addition, the prepared NPs can enhance the tribological performance of lubricating oil. This low-cost, high-performance lubricant additive has tremendous promise for usage in marine engines to minimize operating costs while preserving navigational safety.

“…By the Scherrer equation [10,11] obtained from the relationship (1), The average crystallite size was calculated, revealing that as the temperature rises, all CuZnS films exhibited improved order crystallinity and revealed that with increasing temperature, all CuZnS films showed improvement in crystallinity. where θ is the Bragg diffraction angle, K is the shape factor, which ranges from 0.9 to 1 depending on the material's shape, and the Full Width at Half Maximum (FWHM), is expressed in radians.…”

The structural and optical characteristics of thin CuZnS films were examined in this research.The films were created utilizing the spin coating technique at different temperatures (200, 250 and 300 °C). According to XRD investigations, all compounds showed a polycrystalline structure with a hexagonal structure. The field emission scanning electron microscopy, surface morphology were investigated (FE-SEM). As the temperature is raised, the average particle size increases. The absorption spectra of CuZnS thin films showed that, for all samples, absorption increases as temperature rises for all samples. The optical characteristics of the material, including absorbance and absorbance coefficient, were investigated as well.
