... (JEOL JEM-2010) with an accelerating voltage of 100 kV. TEM samples were prepared by placing a drop of a dilute dis- persion of Cu nanoparticles on the surface of a 400-mesh copper grid backed with Formvar ... Along this line, synthesis of copper nanoparticles with smaller sizes based on simple chemical reduction is highly demanded. Here, we present a facile fabrication o...
