“…Non-uniformities in the lattice, such as faulting, dislocations, antiphase domain borders, and grain surface relaxation all contribute to the lattice strain, as shown in Table . Using the Williamson–Hall eq , − we may determine the crystallite size and lattice strain. Peak broadening in the diffraction pattern because of experimental errors can be calculated using the following formula. β 0.25em cos nobreak0em.25em⁡ θ = 0.25em 0.89 D + 4 ε 0.25em sin nobreak0em.25em⁡ θ where β is the full width at half-maximum, ε is the lattice strain, D is the average crystallite size, θ is Bragg’s diffraction angle, and the radiation wavelength λ = 0.154056 nm.…”

In this cutting-edge research era, silver nanoparticles impose a substantial impact because of their wide applicability in the field of engineering, science, and industry. Regarding the vast applications of silver nanoparticles, in this study, the crystallographic characteristics and nanostructures of silver nanoparticles extracted from natural resources have been studied. First, biosynthetic silver nanoparticles were synthesized using the Pathor Kuchi leaf (PKL) extract as a mediator, and their crystal structures and characteristics were analyzed by UV–visible absorption spectroscopy, Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD), field-emission scanning electron microscopy (FESEM), and energy-dispersive X-ray (EDX) analysis. The average crystallite size of the synthesized silver nanoparticle was determined to be 20.26 nm, and also the lattice strain, intrinsic stress, and dislocation density were measured to be 2.19 × 10–3, 0.08235 GPa, and 3.062045 × 10–3/nm2, respectively. Further, the prepared sample of silver nanoparticles shows four peaks in the X-ray diffraction pattern, which correspond to the (111), (200), (220), and (311) face-centered cubic (FCC) crystalline planes. The outstanding finding of this work was that when the lattice parameters of the precursor were increased, the volume of the material did not considerably change, but the particle size decreased. Second, it was clearly demonstrated that this straightforward method is a clean, cost-effective, environmentally sustainable, nontoxic, and efficient route for the synthesis of silver nanoparticles (Ag NPs) using PKL leaf at ambient temperature, which also satisfies the green chemistry requirements. Finally, this study demonstrates the scope for the production of silver nanoparticles using low-cost natural resources.

“…Furthermore, the mean crystallite size of the synthesized tin oxide nanoparticles was determined using the Scherrer [32] and modified Scherrer [33,34] formulae, showing that these two values are almost the same( D S =16.47 nm and D MS =16.44 nm) which are mentioned in Table 2, 3. Nonetheless, these two methods do not account for the strain throughout the crystals, they only consider the crystallite size effects on the XRD peak broadening.…”

The present study reports a simple co‐precipitation followed by solid state method for the synthesis of tetragonal SnO2 nanoparticles.The nanoparticles were characterized by XRD, FTIR, SEM, DLS, UV‐vis, and PL techniques to examine the structural properties, functional group, morphological and electronic properties. As prepared SnO2 NPs has been used for Fenton‐like degradation of Methylene blue(MB) in presence of solar light in aqueous solution.The structural analysis and Rietveld refinement revealed that the tetragonal SnO2 NPs have been well formed. The mean crystallite size of the synthesized nanoparticles was found to be 16.47 nm using the Scherrer formula.The Williamson‐Hall method determines strain throughout the crystal. The effect of various parameters such as catalyst dose, dye concentration, H2O2 concentration, pH and temperature was examined.The complete degradation of MB was obtained at pH=9. The results obtained from kinetics showed that degradation of MB dye follows pseudo‐first order rate with the rate constant k1 is 7.889×10−2 min−1. From Brunauer‐Emmet‐Teller (BET) surface analysis, we have determined the surface area and average pore size of SnO2 NPs. All parameters were measured by Brunauer‐Emmet‐Teller (BET) surface analysis with nitrogen adsorption‐desorption isotherm.The pore volume and pore diameter was calculated by BJH (Barrett‐Joyner‐Halenda) model.
