Figure 4: Time-dependent synchrotron high-energy XRD patterns of the Ag nanowires during their transformation to hollow Ag–Au alloy nanotubes.
From: Ambient-stable tetragonal phase in silver nanostructures

(a) X-ray diffraction patterns plotted with a time interval of 5 s. (b) Contour plot of the diffraction patterns with a time interval of 1 s. The background caused by the solvent was subtracted for visual clarity. The wavelength of the X-ray beam was 0.1771 Ă….
