In bare MAPbI3, the initial one doublet peak of Pb 4f is at 138.8 eV, and shifts to 138.2 eV as it degrades. The capping layers, on the other hand, initially has two doublet peaks, indicating the presence of two different Pb-bonds on the surface. After 640 min, PTEAI-...
According to all GIWAXS 2D patterns that we obtained (Fig.3), both HaP samples contain three types of crystals, viz. trigonal PbI2, hexagonal (δ-), and cubic α-HaP. We note that δ-HaP was not observed in conventional XRD measurements (Supplementary Fig.7), which suggests that it may...
Small intensity peaks around 30° correspond to crystallized octadecene which remains precipitated if the sample has not been sufficiently cleaned (∗ marked in Fig. 2). The adequate relation of surfactant and ligands, in a mixture of solvents with a proper redox balance (see Experimental Section...

(corrected with 95% iR compensation) present anodic peaks at ∼125 mV, representing the oxidation of α-Ni(OH)2to γ-NiOOH.8The oxygen evolution starts at more positive potentials, and thus NiOOH is believed to be the real host under OER conditions. The formation of NiOOH was further ...

(A) shows peaks for 2600 to 3800, while (B) is for 500–1700 wavenumbers. 2.2. Correlation between QCT Bone Density and Physico-Chemical Parameters The results of the Pearson’s correlation analysis are included in Table 2. In the 14 bone samples, total BMD positively correlated with all...
There have been multiple studies applying XRD, TGA and FTIR to bone research starting in the 1950s, especially in the field of bone structure and regenerative medicine (among others: [41–48]). Certainly, as described above, many studies applied these techniques or other forms of spectrometry ...
