again it gives only an indication of the chromium and nickel contents. In some cases there may also be a number included in the designation; it will appear after the first two letters, e.g., HK40. This number indicates that it is in the middle of thecarbon range. The carbon range is...

Additional evidences for the formation of alloy nanoframes were provided by line scanning analyses of a number of nanoframes in the high-angle annular dark-field STEM mode. As confirmed by the D and E series in Fig. 1, the Cu and Pt are also uniformly distributed throughout the nanoframe. ...
A significant number of SFs have been generated ahead of the crack tip in CrCoNi MEA, with the average SF length increased from 17.5 nm to 48.3 nm (Figs. 2b, j and 3a). In contrast, the SFs in Ni have very limited growth in population and average length (Figs. 2f, n, 3a...

While metalloids like P can create more active Co sites on the surface though the total surface area is low. So by combining both these dopants can provide high surface area with high number of Co active sites. Thus we developed quaternary alloy of Co-M-B-P (where M = Ni, Cr, Mo, ...
Furthermore, P species containing strong electronegative P atoms can capture a large number of positively charged protons to enhance the HER activity [44]. The preparation process of traditional carbon-based catalysts is generally divided into two steps: (i) preparation of carbon substrates (such ...
