“…A bar chart with the EDS mapping of the areas marked in Figure 5c, indicating phase separation in the two areas of the aged CuNi conductor, with Area 1 being Ni-rich and Area 2 being Cu-rich, further elucidating the phase separation at higher temperatures (Figure 5d). As phase separation initiates, [43] CuNW/G, [44] Ni * , [45] Ni ** , [46] Pt * , [47] Pt ** , [48] Pt/Rh, [49] ITO, [50] Au, [51] NiO x , [52] Al [53] and this work; CuNi). d) Plot depicting the data rendered in real-time from the webpage during the test, indicative of the temperature when the furnace was in the 535-570 °C range.…”
