A generic experimental procedure is presented in this work to enhance
the electrical responses of polydimethylsiloxane (PDMS) through
incorporation of conducting polymer nanowires, while maintaining the
desirable mechanical flexibility of PDMS. The conducting polypyrrole

Following our previous work on Cu-Zr nanowire system, in this paper we have shown improvement in various thermo-mechanical properties of nanowire via manipulating the surface atoms. The paper titled "Designing copper–zirconium based nanowires for improving yield strength and plasticity via configuring surface atoms" by Vijay Kumar Sutrakarand D Roy Mahapatra has been published in Journal of Nanoparticle Research.
