Authors: Rafid Saad Dawood  , Khetam Tareq Ahmed
Published: April 2023

The aim of the present work is a synthesis of new fluorene derivatives containing heterocyclic moieties. These compounds were synthesized in four groups, each group containing five compounds. The first group was made up of 2-(3-aryl-2-propenoyl) fluorene derivatives (1a-e) synthesized from the reaction of    2-acetyl fluorene with appropriate aromatic aldehyde in the presence of sodium hydroxide. The other three groups involved compounds produced from the reaction of (1a-e) with hydrazine hydrate (99%) in presence of acetic acid (96%) to give 1-acetyl-5-aryl-3-(fluoren-2-yl) pyrazoline derivatives (2a-e), and with phenyl hydrazine in presence of piperidine to produce 1-phenyl-5-aryl-3-(fluoren-2-yl) pyrazoline derivatives (3a-e), and with hydroxylamine hydrochloride in presence of pyridine to obtain the 5-aryl-3-(fluoren-2-yl) oxazoline derivatives (4a-e). All the compounds of the above three groups were substituted at position (5) in pyrazoline and isoxazoline ring with different aryl groups according to aromatic aldehyde used in the preparation of the first group series compounds. The synthesized compounds were identified by spectroscopic methods: FT-IR and 1H-NMR

Published: April 2023

The new Schiff-base ligand [H2L] 1-(9H-flouren-9-ylidene)-4-phenylthiosemicarbazide and its metal complexes with Mn(II),Co(II),Zn(II)andCd(II) are reported.  The ligand derived from the condensation reaction of (4a,9a-Dihydro-flouren-9-one) with (4-phenylthiosemicarbazide)  in mole ratio of 1:1. Upon complex formation, the ligand behaves as a dianionic bidentate species forming monomeric complexes of general formula [M(L)2] and [M(L)2(H2O)2] , (M=Mn(II), Co(II), Zn(II) and Cd(II). The modes of bonding and overall geometry of the complexes were determined through (FTIR, UV-Vis, 1H.NMR) along with elemental analysis, metal content, and conductance. These studies revealed octahedral geometry for the Mn(II) complex and  tetrahedral for the Co(II), Zn(II) and Cd(II) complexes. Biological activity of the ligand and its metal complexes against gram positive bacterial strain Bacillus (G+) and gram negative bacteria Pseudomonase (G-) revealed that the metal complexes become less resistive to the microbial activities as compared to the free ligand.

Authors: Jassim M. Thabit  , Ali M. Abd  , Firas H. AL-Menshed
Published: April 2023

The 3D resistivity imaging survey was carried out over Um El-Githoaa cavity in Hit area, western Iraq. Resistivity data were collected along four parallel traverses using Dipole-dipole array with electrode spacing of (2m) and (n) factor equal to 6. Inversion 3D models of standard least-squares method and robust constrain method for Um El-Githoaa cavity showed horizontal slices of the 3D resistivity distribution with depth. The first three slices, which represented the resistivity changes from ground surface to depth approximately equal to (3m), showed relatively higher resistivity reflecting the dry sediments of gypsum rocks, and some of these rocks visible on ground surface .The slices after (3m) depth showed the effect of the subsurface cavity by noticeable increasing in resistivity contrast (more than 800 ohm.m)with surround sediment, and the dimensions of the cavity equal approximately to the actual dimensions of this cavity. The comparison between the two methods of inversion appeared that the invers model produced by the robust constrain method has sharper and straighter boundaries, and the dimensions of the Um El-Githoaa cavity appeared closer to the actual dimension of this cavity (maximum diameter equal approximately to 19.3m, while the minimum equal to 15.8m and perpendicular to the first diameter). Therefore, the 3D resistivity imaging survey was delineated Um El-Githoaa cavity at depths ranges from (3 to 6 m). It is concluded that, the dense measurements along 2D lines in small area can be increasing the 3D imaging resolution.

Authors: Ahmed S. M. Al-Janabi
Published: April 2023

Many new mixed ligand complexes of mercury(II) have been synthesized with LH = 4,5-(diphenyl)-1,2,4-triazole-3-thione (diptSH) and tertiary phosphines as co-ligands. The compounds have been characterized by elemental analyses, IR, UV–Vis, molar conductivity, and NMR spectroscopy. In the binuclear complexes (2-5), both Hg atoms have tetrahedral geometry, the Hg atom bonded to three halide ions and one thione ligand (LH) through the sulfur atom. The complex (6) show that thiolate ligand(diptS-) is coordinated as monodentate through the sulfur atom. The dppm behave as bidentate bridging ligand to bonded two Hg(II) ions in the complex (7), Whereas in the complexes (7-10), the thionlate ligand bonded as a monodentate fashion via the sulfur atom, while the diphosphines ligands coordinated as bidentate chelating ligands, and the geometry around the Hg center ion is tetrahedral. And in the complexes (11 and 12), the phosphine bonded as monodentate ligand, and the thionlate bonded via the sulfur atom as monodentate to give tetrahedral complexes

Authors: Sabah Mahmuoud Aman Allah
Published: April 2023

In this paper the mean penetration depths z0 and  Makhov (Implantation) profile I(z,E) were evaluated for low energies positrons(1.5-30/keV)by using a distribution function of  Valkealahti - Nieminen for Germanium for different thicknesses:0.2, 0.4,0.8,1.2,1.4,1.6 μm. The obtained results reveals that the values of  Makhov,s  profile  decreased exponentialy with increasing the positron energy  and profile depths increasing linearly  with increasing  the incident energy. The shape of the Makhov,s  profile reflects the shape of the energy spectrum of the positrons, which  indicates  the annihilation of positrons  inside the material  where  its  wavefunction is delocalized.

This study included preparing samples of the compound (Bi2Ba2Ca2Cu3O10+δ) by the solid state reaction method under a hydrostatic pressure 8 ton/cm2 and annealing temperature 840oC. X-ray diffraction (XRD), scanning electron microscopy (SEM), dc electrical resistivity measurements by four point probe method were used to investigate the microstructural and superconducting properties of Bi¬2223 samples. The X-rays diffraction study for the compound (Bi2Ba2Ca2Cu3O10+δ ) showed that it has Tetragonal type of crystal structure. The partial replacement of the component Ag in Bi, and Sr component  in Ba simultaneously, the compound becomes (Bi2-xAgxBa2-ySryCa2Cu3O10+δ) with (x ,y) values equal to (x= 0.2, y= 0.1, 0.2, 0.3,0.4). The study of the crystal structure test showed that the structure retains on the tetragonal type with a high Tc phases (2223), low Tc phase(2212) and impurity phases, and the critical temperature Tc steps-up from (125K) to (137K) at substitution rate (x= 0.2, y= 0.1). But at increasing the substitution rate for (y) and the stability of (x) rate more than (x= 0.2, y= 0.1), the temperature declines to (108 K). Finally, the microstructural of the samples has been studies and tested by Scanning Electron Microscope for knowing the components' rates in the compound; how the compound partial substitution affect in the components; and specifying the quantitative and qualitative rates of the components in the compound.
