Sc-substituted
BHF nanoplatelets (BHF NPLs) were synthesized hydrothermally at 240
°C, as described previously,3 (link) starting
with a nominal molar ratio of metal nitrates (Fe + Sc)/Ba = 5 and
Fe/Sc = 9. Stable aqueous suspensions of the BHF NPLs were obtained
at pH = 2–2.2, which was adjusted with a 14.3 M solution of
HNO3. The chemical composition of the NPLs was determined
in average to be Ba1±0.08Fe14.9±0.12Sc0.87±0.10Ox, and their
thickness was found to be ca. 3–5 nm.16 (link) The width of the as-synthesized BHF NPLs was determined (see Materials Characterization) from transmission
electron microscopy (TEM) images (as in Figure 1a). For the estimation of surface ligand
fractions and coating densities (for details, see the Supporting Information), we considered an average
width of 50 or 60 nm (Table 1) and a thickness of 4 nm.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
