Please compare with Figure 3(C), "Magnetic hysteresis loop of Gd-SPIONs and AuNFs@MPS", from Roy et al. 2017: https://pubpeer.com/publications/33CB940D42723BAB8B4F737B434E86#5

Please compare with panels C, A, E, G in Figure 6 from Roy et al. (2017), "Confocal microscopic images of showing cellular uptake of AuNFs@MPS after different time intervals: (A, B) 0, (C, D) 0.5, (E, F) 1, and (G, H) 1.5 h."

"Figure 1: (A) XRD spectra of Fe2O3 (MNPs, a), Gd-MNPs (b) and poly@Gd-MNPs (c)."
Middle frame is a stretched version of 1(A), for better comparison with Fig. 1 (A) "XRD pattern ... of SPIONs, SPIONs@silane and MISP", from Kumar et al. https://pubpeer.com/publications/B62F24F474D2D4A49E608D17411A26
Greater similarity than one would expect.
"Figure 3: (A) Cloud point measurement of poly@Gd-MNPs. Mean count rate (in kilo counts per second, kcps), polydispersity index (PDI) and z-average diameter (nm) plotted as a function of temperature (°C) of P(NIPAm)... The inset shows a camera picture of poly@Gd-MNPs below (a) and above LCST (b)."
Please compare with Patra et al. (2015): https://pubpeer.com/publications/EC97AF46B6146D12F981D19486B64A
"Figure 1: ... (C) Cloud point measurement and (D) mean count rate (in kilo counts per second, kcps), poly dispersity index (PDI) and z-average diameter (nm) plotted as a function of temperature (°C) of poly-SPIONs. The inset shows a camera picture of poly-SPIONs below and above LCST."
"Figure 2: TEM, HR-TEM and SAED images of Gd-MNPs (A-C) and poly@Gd-MNPs (DF)."
(A) is more similar than one might expect to (D) of "Figure 1: Characterization of bimetallic Fe/Pd nanoparticle by: (A) UV, (B) XRD, (C) FE-SEM, (D) HR-TEM, (E) EDAX, and (F) FT-IR analyses." of Roy et al. https://pubpeer.com/publications/D9C3389B91C580C3446CFD11E7C2BC
It is unfortunate that the reviewer(s) found the term XRD spectra o.k. The quality of science can be readily evidenced in this terminology viz XRD spectra. (Some authors refer to TG study as TG spectra) It has been noted most papers where powder pattern are shown as XRD spectra always have some problem or other as can be seen in most of the papers authored (and presently under discussion in Pub Peer) by the groups of Rashmi Madhuri and Prashant K. Sharma.
"Figure 2: TEM, HR-TEM and SAED images of Gd-MNPs (A-C) and poly@Gd-MNPs (DF)."
In addition, 2(D) has appeared earlier, as Figure 2(A) in Sharma et al. (2012) https://pubpeer.com/publications/7B00D5EF0CF4FA9F38E56240A8A390
where the "poly@Gd-MNPs" were described as "Representative TEM images of YBO3:Tb3+ nanocrystals annealed at 600 C"
In addition -- Figure 2(B), "HR-TEM ... of Gd-MNPs".
Previously appeared in Sharma et al. (2009), as Figure 3(A) ("HRTEM images of ZnO:Fe nanoparticles for (a) RF1 samples"). https://pubpeer.com/publications/051CE24149D18D3831CDDC82086BC9#3
I am unable to account for the change in inter-layer spacing from one appearance to the next.
"Figure 2: TEM, HR-TEM and SAED images of Gd-MNPs (A-C) and poly@Gd-MNPs (DF)."
Panels (C), (B) and (E) also appeared in Sharma et al. (2009) https://pubpeer.com/publications/0FA8D374CBBE1E31868ED769E9CEF8#3
as "Fig. 2. Representative TEM images of ZnO:Ni nanoparticles, for sample ... RNi8(e), respectively, (f) represents the SAED pattern for sample RNi1. Representative HRTEM images of ZnO:Ni nanoparticles, for sample (g) RNi1 and (h) RNi8, respectively."
Panel (C) made a third appearance in Sharma et al. (2010, where "Fig. 2... (f) Represents the SAED pattern for sample RCo 6 ..."
