Large-scale 3-D interconnected Ni nanotube networks with controlled structural and magnetic properties

Abstract Large-scale, electrically interconnected three-dimensional (3-D) Ni crossed nanotube networks have been fabricated using an electrochemical dealloying method within the crossed nanopores of polymer host membranes. This method paves the way for the easy and cost-effective fabrication of 3-D...
