A noble metal alloy at the nanoscale : The internal structure and the surface composition of bimetallic silver–gold nanoparticles of 30–40 nm diameter were probed by transmission electron microscopy, X‐ray diffraction, and electrochemistry (cyclovoltammetry, underpotential deposition). The elements are not evenly distributed inside each nanoparticle; there is more gold in the core and more silver in the shell. More information can be found in the Full Paper by M. Epple, K. Tschulik, et al. on page 9051.
