    Abstract: In this study, we have represented synthesis of nano spherical nickel using porous Hibiscus rosa-sinensis petals as bio template. Synthesized Nickel nanoparticle thus characterized by SEM, TEM, XRD and wet chemical methods. Spherical Nickel particles of sized between 10nm to 200nm was observed.

    Abstract: Theoretical investigation of the alloy concentration and temperature dependences of the lattice thermal conductivity of silicon-germanium nanowires is performed using the Steigmeier and Abeles model. Phonon scattering processes are represented by frequency-dependent relaxation time approximation. In addition to the commonly considered acoustic thre... Show More

    Abstract: Nonlinear optics to study various phenomena in which the optical properties of the material changes in the presence of light. Polarization of a material system depends non-linearity upon the strength of the applied optical field in this mediums. The Z-scan technique is the best method that by this method we can determine nonlinearity optical proper... Show More
