    Abstract: This paper represents the use of Maple software capabilities in the analyses of the polymer- solvent interactions. It illustrates the advantages of using Maple to estimate Hansen solubility parameters and to predict the polymer-solvent miscibility. The study focuses on the polymers and solvents that are employed in the polymer gel electrolytes. The... Show More

    Abstract: This paper reports the study on structural, morphology and optical properties of electrodeposited tin disulphide (SnS2) thin films. The thin films were synthesise from SnSO4, Na2S2O3 and H2SO4 and were deposited on Indium tin oxide coated glass slide. The films were characterized using X-Ray Diffractometer (XRD), SEM-EDS, AFM and UV-Visible spectro... Show More

    Abstract: The excellent qualities possessed by silicon elastomer when used in designing flexible parts of mechanical systems, make it imperative that we analyze its deformations and distributed axial forces in a matrix of shape memory alloy (SMA) fibers designed as possible appendages for gripping robots. The essence of these analyses is to determine the she... Show More

    Abstract: The structural, elastic, electronic and optical properties of cubic SrVO3 perovskite have been investigated using the first principles pseudo-potential plane-wave (PP-PW) method based on the density functional theory (DFT), within the generalized gradient approximation (GGA). The calculated lattice parameters are in good agreement with the previous... Show More

    Abstract: The anodic oxidation method has been used to prepare thin films of titanium dioxide (TiO2) in acid and alkaline electrolytes. The influence of pH on the structure, the morphology and the photo response of the deposited TiO2 has been evaluated by measuring the current density. The experimental results showed that the photo current response was pH de... Show More

    Abstract: We present an investigation on introducing core-shell Ag@SiO2 nanoparticles (NPs) into dye-sensitized solar cells. Ag@SiO2 present the chemical stability to iodide/triiodide electrolyte, and help to localize most of dye molecules around plasmonic silver nanoparticles (AgNPs), hence increasing the optical absorption consequently the overall conversi...

    Abstract: La0.67Sr0.33MnO3 (LSMO) films were prepared on SrTiO3 single-crystal substrates by the pulsed laser deposition method. X-ray photoelectron spectra (XPS) were measured for the LSMO films as-prepared, annealed in oxygen and in vacuum, respectively. Multiple peaks fitting for Mn 2p3/2 XPS spectra shows that Mn2+ appears and the ratio of Mn3+/Mn4+ incr... Show More

    Abstract: Zn diffusion in III-V compound semiconductors are commonly processed under group V-atoms rich conditions because the vapor pressure of group V-atoms is relatively high. In this paper, we found that group V-atoms in the diffusion sources would not change the shaped of Zn profiles, while the Zn diffusion would change dramatically under group III-atom... Show More
