The purpose of my thesis is to synthesis two new bidentate ligands which were used to prepare series of metal complexes by reacting the ligands with (M+2 = Mn, Co, Ni, Cu, Cd and Hg) Succinyl chloride was used as starting material to synthesis two bidentate ligands (L1) and (L2) by reaction it with 4-chloroaniline (L1) and (4-aminoacetophenone) (L2) in dichloromethane as a solvent, that are: (L1) = N1,N4-bis (4-chloro phenyl ) succinamide (L2) =N1,N4-bis(4-acetylphenyl)succinamide The new ligands were characterize by using spectroscopic study (Fourier-transform infrared spectroscopy (FT-IR), electronic spectra ( UV-Vis) ,nuclear magnetic resonance(1H,13C-NMR), Mass spectra ,Elemental microanalysis (C.H.N.S) and thermal analysis (TGA) , which showed a match with the molecular formulas of these ligands. A series of metal complexes (containing six complexes for each ligand) were synthesized from adding some metal ions (M+2 = Mn, Co, Ni, Cu, Cd and Hg) to the ligand with molecular formulas: ]Cl22(H2O)M(L1)2]Cl2 , [2(H2O)M(L2)2] All complexes that synthesized in this investigation were characterized by solubility, melting point, Fourier-transform infrared spectroscopy, electronic spectra, molar conductivity, magnetic susceptibility measurements, element microanalysis and flame atomic absorption, According to the ola inedresults an octahedral geometric structure of the prepared complexes was proposed. The biological activity of the prepared compounds against three types of bacteria, Escherichia coli (G-), and Pseudomonas (G-) Staphylococcus aureus (G+) were examined, the prepared compounds showed good activity and different from the selected bacteria.
This study was undertaken to prepare Nano zinc oxide (ZnO) by precipitation and microemulsion methods. Scanning electron microscopy (SEM), X-ray diffraction (XRD), FTIR spectrometry, atomic force microscopy (AFM), and Brunauer Emmett Teller (BET) surface area were the techniques employed for the preparation. The particle size of prepared nano ZnO was 69.15nm and 88.49nm for precipitation and microemulsion methods, respectively, which corresponded to the BET surface area 20.028 and 16.369m2/g respectively. The activity of prepared nano ZnO as a photocatalyst was estimated by the removal of ampicillin (Amp) under visible light. This study, therefore, examined the effect of pH in the range of 5-11, initial concen

In this manuscript, a simple new method for the green synthesis of platinum nanoparticles (Pt NPs) utilizing F. carica Fig extract as reducing agent for antimicrobial activities was reported. Simultaneously, the microstructural and morphological features of the synthesized Pt NPs were thoroughly investigated. In particular, the attained Pt NPs exhibited spherical shape with diameter range of 5-30 nm and root mean square of 9.48 nm using Transmission Electron Microscopy (TEM) and Atomic Force Microscopy (AFM), respectively. Additionally, the final product (Pt NPs) was screened as antifungal and antibacterial agent against Candida and Aspergillus species as well as Gram-positive Staphyllococcus aureus and G
