This work aims to provide an overview of the synthesis and characterization method employed for the Graphene/Cobalt nanocomposite, along with highlighting its applications. In this research, we report the synthesis of Graphene/Cobalt nanocomposite using Two-steps Laser ablation technique. The experiments were performed with the first harmonic (1064 nm, 10 ns, 6 Hz) output of a […]
We report the significance of hydrothermal temperature of TiO2 nanoparticles on the crystallinity, band gap and the photocatalytic degradation of congo red dye. These nanoparticles are synthesized by hydrothermal method at 120 ˚C, 140 ˚C and 160 ˚C. The anatase phases of the samples are confirmed from the X-ray diffraction pattern and the surface morphology […]
AbstractIn this study, the effect of oxygen content on a thin copper oxide layer deposited on BK7 and steel substrates by DC magnetron sputtering were investigated. Argon as working gas with impurity of 99.9% and various oxygen ratios were used to sputter a pure Cu cathode target in a cylindrical geometry. The produced samples were […]
AbstractGamma ray effect has been worked out on PMMA/PS blends at different concentrations. The optical constants such as the absorption coefficient, refractive index are calculated, and optical energy gap (direct/indirect) has been studied before and after irradiation. Transmittance, absorbance, and reflectance spectra of pure and blends polymers are investigated.
AbstractIn this work, the copper films were deposited on quartz substrates by DC magnetron sputtering method and then, the prepared films were annealed in air atmosphere at different annealing temperatures. Before annealing, some of the copper films, treated by oxygen plasma, for comparison of the results. The structural and morphological properties of the films have […]
AbstractNew sets of molecules containing tri-phenyl-amine (TPA) core and thiophene unit with amide and imine functional groups are designed, synthesized, characterized, and compared. These are solution processable small molecules with high mobility. The newly designed molecules have better solubility due to the C=N (imine) and CONH2 (amide) moiety as compared to the established molecules with […]
AbstractIn the present work, the optical properties of a GaAs quantum wire with a parallelogram cross section are studied. In this regard, we have used the expressions for the optical properties obtained by the compact-density matrix formalism. Here, we have investigated the intersubband optical absorption coefficients and refractive index changes as a function of the […]
