Synthesis, Characterization and Functionalization of P3HT-CNT Nanocomposite Thin Films with Doped Ag2O
...Show More Authors

This research focuses on the synthesis of carbon nanotube (CNT) and Poly(3-hexylthiophene) (P3HT) (pristine polymer) with Ag doped (CNT/ P3HT@Ag) nanocomposite thin films to be utilised in various practical applications. First, four samples of CNT solution and different ratios of the polymer (P3HT) [0.1, 0.3, 0.5, and 0.7 wt.%] are prepared to form thin layer of P3HT@CNT nanocomposites by dip-coating method of Ag. To investigate the absorption and conductivity properties for use in various practical applications, structure, morphology, optical, and photoluminescence properties of CNT/P3HT @Ag nanocomposite are systematically evaluated in this study. In this regard, the UV/Vis/NIR spectrophotometer in the wavelength range of 350 to 700 nm is used to investigate the absorption, transmission spectrum, extinction coefficient (k) and refractive index of the samples prepared at room temperature. The XRD results indicate a slight increase in the crystallite size of the synthesized (CNT/ P3HT@Ag) nanocomposite compared to CNT/P3HT nanocomposite, which can be attributed to the better dispersion of the P3HT and its favorable wrapping around the carbon nanotube structures. FESEM results show that the Ag nanoparticles are acting as a bridge between the CNT and P3HT, creating a strong bond between the two materials that is strong enough to form thicker tubular structures.  An appreciable increase in absorbance intensity (approximately 552 nm) is obtained by adding silver nanoparticles to the CNT/P3HT matrix at 0.5% of P3HT. Additionally, the prepared CNT/P3HT@Ag thin films show greater transmittance – more than 42%, 45%, 49%, and 48% for P3HT concentrations of 1%, 3%, 5%, and 7%, respectively. The preparation of the samples' extinction coefficient (k) and refractive index data show that the inclusion of silver nanoparticles to the CNT/P3HT nanocomposite matrix has a significant improvement over the previous samples (CNT/P3HT composite).

Automated breast ultrasound: A comparison study with handheld ultrasound in detection and characterization of lesions in mammographically dense breast
...Show More Authors

Background: Although mammography is a powerful screening tool in detection of early breast cancer, it is imperfect, particularly for women with dense breast, which have a higher risk to develop cancer and decrease the sensitivity of mammogram, Automated breast ultrasound is a recently introduced ultrasonography technique, developed with the purpose to standardize breast ultrasonography and overcome some limitations of handheld ultrasound, this study aims to evaluate the diagnostic efficacy of Automated breast ultrasound and compare it with handheld ultrasound in the detection and characterization of breast lesions in women with dense breasts.

...Show More Authors

The research includes the synthesis and identification of the mixed ligands complexes of M(II) Ions in general composition [M(Lyn)2(phen)] Where L- lysine (C6H14N2O2) commonly abbreviated (LynH) as a primary ligand and 1,10-phenanthroline(C12H8N2) commonly abbreviated as "phen," as a secondary ligand . The ligands and the metal chlorides were brought in to reaction at room temperature in ethanol as solvent. The reaction required the following molar ratio [(1:1:2) (metal): phen:2 Lyn -] with M(II) ions, were M = Mn(II),Cu(II), Ni(II), Co(II), Fe(II) and Cd(II). Our research also includes studying the bio–activity of the some complexes prepared against pathogenic bacteria Escherichia coli(-),Staphylococcus(-) , Pseudomonas (-), Bacillus (-)

COUPLED VERTICAL – TORSIONAL AND LATERAL FREE VIBRATION OF THIN-WALLED CURVED BEAM
...Show More Authors

This study is concerned with the derivation of differential equation of motion for the free coupled vertical – torsional and lateral vibration of opened thin-walled curved beams. The curved beam to be considered in this study is of isotropic opened thin – walled (I) section with equal top and bottom flanges. The derivation depends on Hamilton's principle which required finding the potential and kinetic energy of the curved beam section due to internal stresses and all types of movements (Vertical,Torsional and Lateral) .The effect of restrained warping displacement is also considered in this study. Three differential equations are derived for vertical, torsional and lateral movement .and approximate solutions are developed by using the
