Forty-five samples, at 10 cm resolution, yielded 45 taxa, which could be assigned to four biozones.
In Fig. 3c, the lattice spacing is 0.335 nm, which could be assigned to the plane [110] of SnO2 [22].
The diameter derived from TEM was lower than that from DLS, which could be assigned to the dehydration and shrinkage of the micelles during drying.
All samples showed two distinct peaks at −99.7 and −109.6 ppm, which could be assigned as surface vicinal silanol groups (Q3) and framework silica (Q4), respectively[27].
Additional bands also appeared at 2340 and 1640 cm−1, which could be assigned to O-H stretching vibration and molecularly adsorbed H2O, respectively [41].
However, for L5RhZ spent catalysts, there was a peak observed at about 32° which could be assigned to the formation of a separate perovskite (LaRhO3) phase.
The CdSe spectrum shows three distinct resolved electronic transitions, which could be assigned to the excitonic absorption features of nanosized CdSe [28] as predicted theoretically [29].
In addition, the appearance of the bands at 2920 and 2846 cm−1 was also observed, which could be assigned to the methyl stretching in PEI molecules.
There is a very small peak observed at 730 °C which could be assigned to the same species as seen over the L2RhZ at 710 °C.
The 1H NMR spectrum displayed signals for 21 protons which could be assigned to five methyl, two methylene and two methine groups according to the DEPT data.
The low frequency region showed four signals at δ 181.0, 172.1, 144.0 and 126.8, which could be assigned to O-acetyl, lactone ester and trisubstituted olefinic carbons.
