Characterisation of the BixSn1-x nano-alloys. a–d TEM images of the nano-alloys prepared by liquid phase ultrasonication of Bi–Sn bulk alloys with different compositions. Scale bars: 100 nm. e–h Size distribution of the particles with their median and mean values indicated. i, j Control samples prepared with Sn metal (i) and Bi metal (j). The inset figures show the AFM topography and the thickness profiles along the dash line of the Sn and Bi particles. Scale bars: 200 nm. k DSC curves showing the melting (solid lines) and solidification (dash lines) trends of the samples. l XRD patterns of the samples
