“…At an RTA temperature of 500 °C, XRD patterns clearly exhibited a strong peak of (002) and the formation of a well-crystallized AlZnO, Al2O3, and Al2O3-doped ZnO structure. Further, Figure 2c shows the Al2O3 as-deposited sample, and the crystalline phase of Al2O3 can be clearly observed to have characteristic XRD peaks at 46.71°, 61.37°, and 67.94, and diffraction peaks of (400), (511), and (440), respectively [17]. The XRD peaks of AlZnO, Al2O3, and Al2O3-doped ZnO film increased in intensity with annealing, which may have been caused by the enhancement of lattice structures and the formation of higher peak intensities.…”

In this study, ZnO, AlZnO, Al2O3, and Al2O3-doped ZnO-sensing membranes were fabricated in electrolyte–insulator–semiconductor (EIS) structures. Multiple material analyses indicate that annealing at an appropriate temperature of 500 °C could enhance crystallizations, passivate defects, and facilitate grainizations. Owing to their material properties, both the pH-sensing capability and overall reliability were optimized for these four types of membranes. The results also revealed that higher Al amounts increased the surface roughness values and enhanced larger crystals and grains. Higher Al compositions resulted in higher sensitivity, linearity, and stability in the membrane.

Plant extract exhibited unique therapeutic characteristics due to their high content of chemical formulas with multiple medical effects. The plant extracts have shown a great advancement in controlling cardiovascular and metabolic disorders, as well as, it was used as antibacterial, antifungal, anti-cancer, and anti-inflammatory agents. Cinnamomum has been used a medical herbs from ancient times along with its uses as spice in food. Cinnamomum oild and extract have shown a great perspective in many areas of human health. We have aimed to prepare an ethanolic extract from dry cinnamomum powder, and investigate its influence in vitro against four types of bacteria and one fungal strain, and again in vivo as wound healing agent in rats. The results have shown that cinnamomum extract in ethanol was exhibited good effect in growth inhibition of escherichia coli, klebsiella sp, Staphylococcus epidermidis and Staphylococcus aureus, as well as Candida albicans. The greatest effect of cinnamomum extract was obtained against the Gram positive bacterial strains S. epidermidis and S. aureus. Furthermore, cinnamomum extract has shown to be a good wound healing agent, in which rats whom treated with cinnamomum extract have shown a faster healing compared to control rats starting from the day 7. These effects make cinnamomum to be very useful in the medical field generally, and in inflammation line specifically.

“…Pyrex tube is used as a reactor. The reactor is cooled by ice bath to avoid the temperature rising as a result of the UV irradiation [19][20][21][22][23][24]. Accordingly, 30 ml of 0.02 mole of urea is added slowly (one drop per second) to 30 ml, 0.01 mole Ni(NO 3 ) 2 with magnetic stirrer at 30 C˚.…”

In this project, we report on the prepare of nickel oxide nanoparticles (NiO NPs) via a photolysis method using UV lamb followed by calcination at 400 C for 3 h. the synthesized Nano-powder were investigated field emission scanning electron microscope (FE-SEM), photoluminescence spectroscopy (PL) and X-ray diffraction (XRD). The SEM image confirmed the crystal structure of the synthesized NiO nanoparticles with an average particle size of 23 nm, and the XRD analysis revealed the absence of impurity peaks. The optical properties were analyzed using photoluminescence spectroscopy (PL), and the bandgap was determined to be 3.4 eV. The semiconductor property, which can be exploited for solar cell applications, is responsible for the broad bandgap. To make dyesensitized solar cells (DSSC), we used photo-chemically synthesized NiO NPs as a photoanode. Two counter electrode were used in this study: Graphene oxide Nano-Sheets and Graphene oxide\silver nanocomposite. cibacron brilliant red B is one of the dyes that are used in the textile factory of Wasit Governorate, and the rest of it is often discarded as waste water Which we used in our study as a photosensitizer. The open-circuit voltage (Voc), short t current density (Jsc), fill factor (FF), and efficiency (h) were determined from the J-V curves, where efficiency was between 0.231 to 1.47 %, at 100 mW/cm2. Finally, it can be confirmed that the presence of nickel oxide nanoparticles with a cibacron brilliant red B dye can improve the performance of dye-sensitized solar cells.
