Size and Shape effect on Melting point of Nanoparticles

The uniqueness and distinctiveness of nanoscience and nanotechnology especially with regard to its pervasiveness into virtually all spheres of human life, explain why their potential impacts will exceed those of all other conventional technologies hitherto developed. The convergence of the newly emerging technologies of the 21st Century have the potential to revolutionize social and economic development and may offer innovative and variable solutions for the most pressing problems of the world communities and their habitat. The melting property of the materials in nanodimensions with special configuration of the cylindrical shape is considered in the investigation. A new thermo dynamical model is developed to derive the particle size with respect to radius of curvature and the temperature of the nanoparticle. The size and shape dependent temperature of B4C, GaN, Au, Ag nanoparticles are determined using the numerical thermodynamical model, where spherical and cylindrical shapes of the nanoparticle are considered with respect to its radius of curvature.
