X-ray diffraction (XRD) analysis confirmed the crystalline nature of the AgNPs, revealing distinct diffraction peaks at specific 2θ angles (38.2°, 44.3°, 64.5°, and 77.4°) corresponding to...

Abstract− Silver nanoparticles were synthesized by micro emulsion route in W/S ratio of 5 at room temperature. X-ray diffraction (XRD) pattern reveals FCC structure of Ag nanoparticles. Spherical shape of Ag nanoparticles of average particle size 5.0 to 12.0 nm were observed by transmission electron microscopy.

The XRD pattern illustrates that Ag + ions were reduced to Ag • in the presence of nanocurcumin and the energy supplied by ultrasonic waves. ...

XRD patterns of Ag (100), Ag (110), and Ag (111) crystals as well as the electrodeposited and PVD polycrystalline silver films. This paper attempts to identify key factor (s) for highly...

18 hours ago · Microstructure of NP-Ag. Figure 1 presents the XRD patterns of the Ag 20 Zn 80 alloy before and after dealloying. It can be seen that the diffraction peaks of the alloy match those of the standard PDF card (JCPDS 00–025–1325), showing a single phase of Ag 0.22 Zn 0.78 with a space group of P63/mmc. The diffraction pattern of alloy has four sharp peaks at 40.8°, 42.3°, 56.1° and 75.3 ...

Oct 25, 2021 · The XRD result was confirmed the formation of Ag NPs and matched with the JCPDS card no 87-0719. The average particles size was found to be 22 nm by SEM and TEM results. FT-IR results also exhibited support for the 4 mL of S. glauca bark extract complete reduction of the functional group.

18 hours ago · The average crystal size of Ag NPs in all diffraction peaks was calculated using the Debye–Scherrer formula, with an average crystal size of about 24.07 nm for G–Ag NPs and 5.91 nm for C–Ag NPs. Extra peaks appeared in the XRD pattern due to organic molecules present in the plant extract.

3 days ago · 2.3 XRD study. The as-prepared green nanocomposite was subjected to phase spectrum analysis to reveal its crystalline nature. The high-intensity peaks possess wurtzite structure as reported in the previous work [].The additional dominant peaks correspond to 2θ (in degrees) = 38.2°, 44.1° (JCPDS 04–0783) [] is also noticed due to …

The FTIR and EDX confirmed the formation of Ag nanoparticles without a trace of impurities. The XRD spectra revealed that the amorphous sample at 30 °C had transformed into the cubic crystalline nanostructures at the calcination temperature of 400 °C and higher.

Dec 5, 2012 · Namely, silver–gold alloy and core(Ag)–shell(Au) type nanoparticles were synthesized at various Ag/Au ratios using only sodium citrate as reductant without any stabilizers. The synthesized NPs were characterized by different structure analysis methods.
