"Abstract Purpose: Zinc Oxide Nanoparticle (ZnO NPs) production has become more common because of the benefits of the green strategy, which include its ease of use, environmental friendliness, and cheap operating costs. In order to accomplish the goal of green chemistry, the green synthesis process also uses safe solvents like water and ethanol. ZnO NPs are among the metal oxide-NPs used in antibacterial and bioremediation applications. Materials and Methods: Energy Dispersive X-ray spectroscopy (EDX), Fourier Transform Infrared spectroscopy (FT-IR), X-Ray Diffractometer (XRD), and Field Emission Scanning Electron Microscopy (FESEM) were used to analyze the green-produced ZnO NPs. Results: ZnO nanoparticles have an average size of 22.89 nm, which is corroborated by FESEM pictures, indicating that the particles are tiny. The excellent purity of ZnO NPs has been confirmed by EDX data. The antibacterial activity of ZnO NPs was assessed against a few dangerous pathogens. Zinc oxide nanoparticles were shown to have an interesting antibacterial action against both gram-positive and gram-negative bacteria at micromolar concentrations because they exhibit the maximum diameter of inhibition zone at concentrations 100 mg/ml of S. aureus, E. coli, K. pneumonia, Acintobacret spp, S. fecalis reaching (27,19,18,17, and 14) mm, respectively while S. pneumonia were resistant.The ZnO NPs recorded at a concentration of 12.5 mg/ml lowest areas of the inhibition zone against the same isolates reaching (16, 11, 11, 12, and 10) mm while S. pneumonia were resistant, respectively, as well. Conclusion: ZnO NPs, since they have excellent antibacterial properties, and are biocompatible, they will open up a new line of inquiry for antibacterial agent research because they are stable, nontoxic, and harmless.

"ABSTRACTIntroduction: disposal of heavy metals into the water as a result of industrial development might cause a threat Health and the environment. aim of this study was to assess the uptake of Co2+ from aqueous solutions via NiO/ γ-Al2O3 nano catalysts. Method: the main variables that affect the percentage of metal removal were assessed. It took about 50 minutes to attain equilibrium for the elimination of Co+2 ions. It was discovered that raising the adsorbate concentration and increasing the surface weight somewhat lowered the removal of cobalt ions. Results: the removal of cobalt ions was shown to depend on temperature, due to ecothermic natural of this prosess increasing temperature associated with decrease the elimination.Conclusions: the adsorption seems to be spontaneous, exothermic, and less random according to calculated values of the thermodynamic functions (∆G, ∆H, and ∆S) of the adsorption. After the data were fitted into a number of kinetic models, including the Elovich model, pseudo-first order, pseudo-second order, and intraparticle diffusion equations, it was discovered that the pseudo-second-order model performed the best at describing the adsorption, with a high correlation factor (R2).Keywords: Thermodynamics; Kinetics; Adsorption; Cobalt II; Nio/Γ-Al2O3 Nanoparticles.RESUMENIntroducción: la eliminación de metales pesados en el agua como resultado del desarrollo industrial puede causar una amenaza para la salud y el medio ambiente.El objetivo de este estudio fue evaluar la absorción de Co2+ de soluciones acuosas a través de nanocatalizadores de NiO/γ-Al2O3.Método: se evaluaron las principales variables que afectan el porcentaje de eliminación de metales. Se tardó aproximadamente 50 minutos en alcanzar el equilibrio para la eliminación de iones Co+2.

Abstract: Aluminum is widely used as a material in automobiles, aviation, household appliances, containers, and electronic devices The resistance of aluminum against corrosion in aqueous media can be attributed to the rapid formation of oxide films on the surface. However, aluminum gets easily corroded in the presence of corrosive acids. Studies of the corrosion behavior of aluminum in different aggressive environments have continued to attract attention because of its important applications. The study of Cydonia Vulgaris leaves extract (CVL) as a corrosion inhibitor for AA2024-T3 aluminum alloy in 1 M H3PO4 acid solution using weight loss method was investigated at 25, 35, 45 and 55°C. The results revealed that CVL leaves in 1 M acidic environment decreased the corrosion at various concentrations considered. Higher inhibition efficiency for AA2024-T3 aluminum alloy of up to (94.58%) was produced at a higher levels of inhibitor concentrations and temperatures. The adsorption of CVL extracts was found to obey the Langmuir adsorption isotherm model. The values of the free energy of adsorption were more than –20 kJ/mol which is indicative of a mixed mode of physical and chemical adsorption. Activation enthalpy (ΔH) and activation entropy (ΔS) of AA2024-T3 aluminum alloy corrosion was found to be (48.7570 kJ·mol–1), (–0.1782 kJ·K–1) and (31.9920 kJ·mol–1), (–0.1873 kJ·K–1) in the absence and presence of the extract, respectively.

"Abstract. It is well known that supported (Co) or (Ni) molybdenum/alumina catalysts are extensively used in hydrotreating (HT) processes for the production of environmentally friendly fuels, and these catalysts have been in need of extensive studies in term of their use and deactivation. This work demonstrate a comparative physical and chemical study of virgin and spent NiMo-γ alumina catalysts and characterized them by thermo gravimetric analysis (TGA), field emission scanning electron microscopy (FESEM), atomic force microscope (AFM) and fourier, transform, infrared ,spectroscopy (FTIR). It was noted that there is obvious changes in structural, textural, particle size, physical properties, such as densities, porosity of the virgin catalysts with use as a result of carbon deposition and change in its structural components."

"Abstract. Bismuth ferrite (BiFeO3) was synthesized by the sol-gel method and the structural properties have been examined via the use of XRD technique. Crystallite size estimated through the use of Scherrer equation for samples calcined at a temperature of 300◦C and 400◦C for two hours respectively, which clarify the increase in crystallite size as the temperature increases and also XRD indicated the fact that in addition to the formation regarding single phase BiFeO3 an impurity phase has been identified. Diagnosing the samples, showed that BiFeO3 has rhombohedral structure. AFM test for samples calcined at (300 and 400◦C) proved that the particle size is in nanoscale and the grain size of bismuth ferrite increases with the increase in temperature. "
