Poly methyl methacrylate (PMMA) and Polycarbonate (PC) are low cost polymer materials which can be easily transformed into desired shapes for various applications. However, they have poor mechanical, thermal and electrical properties which are required to be enhanced to widen their scope of applications specifically where along with high strength, rapid heat transfer is essential.

In this paper, the analysis of the influence of nano-sized defects on the critical current phenomena in the multilayered HTc superconductors is presented. The formation of the pinning potential barrier, determining the superconducting transport current flow, current-voltage characteristics, shapes and critical current limitations are discussed. Various initial positions of pancake vortices in the respect to […]
