Figure 3From: A versatile synthesis method of dendrites-free segmented nanowires with a precise size controlSEM and STEM images of nanowires. (a) SEM image of PAA filled with Cu in dendrites (branched pores at the pore bottom) and Au-Ni segmented nanowires, with 400 and 800 nm, respectively and (b) STEM image of a suspension of dendrites free Au/Ni segmented nanowires.Back to article page
