Published: November 2020

Abstract
The qualitative information about the interaction between 2-{[p-chlorophenylimino]methyl}phenol as attracting chelating Schiff base ligand (HL) with cobalt(II) and manganese(II) ions have been discussed by using the data of spectroscopy (IR, UV-Visible) and 1H NMR resonance techniques. The electrochemical properties of these species have been carried out by using cyclic voltammetry studies to see the differences in the potential and activity behavior during and after the electron transfer process. The cyclic voltammetry behavior of ligand exhibited an irreversible one-electron transfer and redox diffusion-controlled process due to the linearity relationship between redox peaks current and square root of scan rates. The cyclic sweep for CoL and CoL2 complexes appeared two irreversible oxidation peaks but with different values and positions, while the cyclic sweep of MnL and MnL2 complexes appeared several redox peaks, which related to the formation of various manganese redox species. All complexes had a deviation of current and potential to more anodic values when the cyclic sweep was applied at different scan rates. A positive shift was observed for CoL2 and MnL2 complexes may be to the electron-donating and electron-withdrawing properties of phenyl substituted group.

There are several physical or chemical synthetic methods have been used to prepare transparent CdO films as described by many researchers. The X-ray diffraction study has confirmed the formation of CdO with nano-size scale. For this research CdO/FTO thin film has been prepared by electrolysis. The thin film is investigated by XRD, SEM and AFM surface morphology properties. XRD analysis showed that CdO films are a polycrystalline and exhibit cubic crystal structure with (111, 200, 311 and 222) orientation and the preferred orientation is 111. AFM and SEM were applied to study the morphology and estimate the surface roughness of the films obtained. (RMS) found that film roughness was 21.7 nm. The CdO film are n-type semiconductors and possess a direct optical band gap around 2.4 eV as shown in optical property studies.

Published: November 2020

Abstract
(NiO) 1-x (ZnO) x compounds were prepared with different composition ratios. The compounds were obtained by mixing Nickle oxide and zinc oxide in the appropriate ratio and sintered at 1000°C for six hours. Pulsed laser deposition (PLD) method which is simple and inexpensive method was used to deposit (NiO) 1-x (ZnO) x thin films on glass substrate at ambient temperature. Structural, optical and properties were investigated. The structures investigation obtained from x-ray diffraction showed that the prepared of compound as well as thin films have polycrystalline structure where the diffraction peaks were identical with the cubic NiO and hexagonal ZnO for x=0 and 1.0 while the structure of the residual x values was identical with the both phases. The average values of the crystallite size increases from 29.3 nm to 32.4 nm when x increases from 0 to 1.0. Thickness interferometry measurement showed that thickness of the prepared thin films was ≈150 nm. The optical absorbance and transmittance spectrum provided from UV-spectrophotometer were used to estimate the optical parameters like optical energy gap Eg, refractive index, extinction coefficient and real and imaginary dielectric constants. The data showed that the optical energy gap as well as the optical constants decreases with the increasing of ZnO content in the prepared thin films.

Abstract
The optical properties for adding (ZrC) nanoparticles to (PVP-PVA) were studied. The Poly(vinyl alcohol) and poly(vinyl pyrrolidone) were blended and films were obtained by the casting method. Zirconium carbide nanoparticles (ZrC) were added with different weight percentages (4 wt.%, 8 wt.%, 12 wt.% and 16 wt.%) to the (PVP-PVA) blend. The wavelength range used to measure the optical properties is (220-820) nm. Analyzing the results it is found that the absorbance (A) decrease by increasing the (ZrC) nanoparticles concentrations, while the coefficient of absorption (α), coefficient of extinction (k), index of refraction and the constants of real and imaginary (∈
1, and ∈
2) increased by increasing the concentration of (ZrC) nanoparticles. The gap of energy (Eg
) of (PVP-PVA) blend increases with the increasing of (ZrC) nanoparticles weight percentages.

Abstract
Iraq is facing a major environmental crisis due to oil-spills which polluted the Tigris River and caused many problems in the environment depending on the volume of the oil spilled. Therefore these problems need emergency solutions and one of the solutions is treatment using Advanced Oxidation Processes (AOPs). In this research the degradation of acidic aqueous solutions of the synthetic diesel oil water emulsion has been studied by advanced oxidation processes (AOPs) using Fenton reagent (Fe2+/H2O2). The effect of different process parameters, such as pH, oxidant’s dose (FeSO4/H2O2) and the reaction times on the removal of diesel oil were investigated in terms of chemical oxygen demand (COD). At an optimum concentration optimum of [H2O2] = 11×10−2 M; [Fe2+] = 7.4×10−3 M, pH=3.5 and reaction time 60 min reduced COD 65% of diesel oil at [Diesel Oil] = 1300 ± 23 mg O2/L. The real oily wastewater was collected from Baghdad south gas power plant-2 and its composition is unknown. The treatment of this wastewater by Fenton oxidations under optimal conditions were removed 86% of the initial COD and 97 % of total petroleum hydrocarbons TPH of the oily wastewater.

Abstract
This study was conducted at the Microbiology Laboratory of the Department of Environmental Science - College of Science - University of Kufa with the aim of isolating and diagnosing fungi isolated from the rice field at the Rice Research Station in Al-Mishkhab in Najaf Governorate. Fungi isolates were diagnosed using the Polymerase Chain Reaction (PCR) technique and nucleotide sequence determination for DNA products multiplied using the ITS1 and ITS4 prefixes. The results of analyzing the nucleotide sequence of the double DNA products of fungal isolates isolated in this study and using the BLAST program showed that some fungal isolates in this study refer to Pencillium citrinum (1), others belong to Alternaria alternata (2), Aspergillus rugulosus (3), F. chlamydosporum (4). Trichoderma harzianum(5) showed a difference in the sequence of some nitrogenous bases for DNA products. Aspergillus flavus (6), Penicillium Spinulosum (7). The results showed that two isolates of fungi isolates isolated in this study (Aspergillus rugulosus and Aspergillus flavus) were not registered formerly at the National Center for Biotechnology Information (NCBI), so they were registered under the numbers MT356126 and MT358845.
