Green Synthesis of ZnO Nanoparticles Using Prosopis fracta Extract with Two Solvents and Study of Their Biological Activities

International Journal of Psychosocial Rehabilitation (Issue: 10) (Volume: 24)

Abstract The main goal of this paper is a green synthesis of zinc oxide nanoparticles with extracts of Prosopis fracta (growing in the Iraqi Kurdistan region) using two solvents, first with water (Zn-NPs-W) and second with methanol (Zn-NPs-M). The prepared nanoparticles characterizations were confirmed by UV-Vis absorption spectrophotometry; Fourier transforms infrared spectroscopy (FT-IR); scanning electron microscopy (SEM); X-ray Diffraction (XRD); and Transmission Electron Microscopy (TEM), in order to determine which solvent is more favorable in terms of particle size, particle agglomeration, and particle separation. The particle size of Zn-NPs-W was found to be 25 nm with a rod shape, while Zn-NPs-M had a particle size of 35 nm which is a wide range and gives a deformed rod shape. Further, it has been shown after testing the antibacterial activity of the two different sizes of the Zn-NPs (25, 35) nm against both gram-positive bacteria such as micrococcus species (M. species) Staphylo epidermidis (S.epidermidis); gram-negative such as Acinetobacter baumannii (A. baumannii), Pseudomonas aeruinosa (P. aeruinosa), and yeast Candida Albicans (C.albicans), with a different effect on bacteria. The most critical advantages of this process are the environmentally friendly and fast synthesis for both Zn-NPs-W and ZnNPs-M.

Preparation and Characterization of some Transition Metal Complexes with Two Mixed Ligands Macrocyclic and Ligands PPh3

Rafidain Journal of Science (Issue: 4) (Volume: 28)

A new ligand (3,4,6,14,15,17,23,24-octaazatricyclo [17.3.1.18,12] tetracosa-1(23),8(24),9,11, 19, 21- hexaene - 2,5,7,13,16,18 – hexaone), (CHT) was been prepared from the reaction of pyridine-2,6-dicarboxylic acid with semicarbazide using microwave irradiation in solid state. The ligand is reacted with some transition metal(II) ions to form complexes of the type [Co(CHT)]Cl2, [Fe(CHT)Cl]Cl and [M(CHT)Cl2] where (M=Mn(II), Ni(II), Cu(II) and Zn(II)). Complexes of the type [Ni(CHT)(PPh3)]Cl2 and [M(CHT)(PPh3)Cl]Cl where (M=Mn(II), Fe(II), Co(II), Cu(II) and Zn(II)), were prepared by the reaction of the above complexes with triphenylphosphine(PPh3) in a 1:1 molar ratio. All the complexes were characterized by (C,H,N) analysis, metal content analysis, molar conductance, magnetic moment measurements, electronic and IR spectroscopy, as well as the ligand was characterized by 1H,13C -NMR. The electronic spectra and magnetic measurements indicate that the complexes have octahedral environment around the metal ions, except cobalt complex have square planer geometry.

Rafidain Journal of Science, (Issue: 5) (Volume: 24)

In this research, a new ligand 3,4,6,13,14,16-hexaazatricyclo [16,2,2,28,11] tetracosane- 2,5,7,12,15,17-hexaone), (DHC) was prepared from the reaction of cyclohexane-1,4-dicarboxylic acid with semicarbazide using microwave irradiation in solid state. Then, it was reacted with some transition metal(II) ions to form complexes of the type [M(DHC)Cl2], [M(DHC)]Cl2, where M = Mn(II), Fe(II), Co(II), Ni(II), Cu(II) and Zn(II). Adducts of the type [M(DHC)(PPh3)Cl]Cl and [M(DHC)(PPh3)]Cl2, were prepared by the reaction of the above complexes with triphenylphosphine in a 1:1 molar ratio. The prepared complexes and adducts were characterized by (C,H,N) analysis, metal content analysis, molar conductance, magnetic moment measurements, electronic and IR spectroscopy, as well as the ligand was characterized by 1H,13C -NMR spectroscopy. The electronic spectra and magnetic measurements indicate that the complexes have octahedral environment around the metal ions.
