“…The diffraction pattern shows the crystallinity and phase structure of biosynthesized CoFe 2 O 4 nanoparticles. The obtained biosynthesized CoFe 2 O 4 nanoparticles 2-theta values coincide with standard cubic phase CoFe 2 O 4 JCPDS card number 22-1086 [ 25 , 26 ], and their (hkl) plane values are (220), (311), (222), (400), (422), (511), and (400) respectively. The cubic spinel ferrites of biosynthesized CoFe 2 O 4 nanoparticles crystallite size were calculated by the Debye-Scherrer formula [ 25 ], with their calculated size being 24 nm.…”

“…Methylene Blue (MB) is one such toxic and carcinogenic dye, and its easily soluble and highly stable cationic dyes. Direct and indirect exposure of MB dye approaches are very harmful and a major threat to safety, the environment, and microorganism evolution [ 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 ]. Additionally, ferrites have important photo-catalytic properties that are useful for many industrial processes, including the oxidative dehydrogenation of hydrocarbons [ 17 ], oxidation of compounds [ 18 ], and decomposition of alcohols and peroxides [ 15 ].…”

Biogenic CoFe2O4 nanoparticles were prepared by co-precipitation and Hibiscus rosa sinensis plant leaf was used as a bio-reductant of the nanoparticle productions. The biosynthesized CoFe2O4 nanoparticles were characterized by XRD, FTIR, UV, VSM, and SEM via EDX analysis. The cubic phase of biosynthesized CoFe2O4 nanoparticles and their crystallite size was determined by XRD. The Co-Fe-O bonding and cation displacement was confirmed by FTIR spectroscopy. The presence of spherically-shaped biosynthesized CoFe2O4 nanoparticles and their material were confirmed by SEM and TEM via EDX. The super-paramagnetic behaviour of the biosynthesized CoFe2O4 nanoparticles and magnetic pulse was established by VSM analysis. Organic and bacterial pollutants were eradicated using the biosynthesized CoFe2O4 nanoparticles. The spinel ferrite biosynthesized CoFe2O4 nanoparticles generate radical and superoxide ions, which degrade toxic organic and bacterial pollutants in the environment.

“…These characteristic peaks are related to the PbI 2 nanomaterials inside the composite. The crystal size of the prepared nanomaterial is calculated using Scherrer’s formula, Equation (1) [ 31 , 32 ]. This equation depends on many factors such as the width half maximum (W), the X-ray wavelength (λ), dimensionless factor (k), and Bragg angle (θ).…”

This study is very promising for providing a renewable enrgy (H2 gas fuel) under the elctrochemical splitting of the wastwater (sewage water). This study has double benefits: hydrogen generation and contaminations removel. This study is carried out on sewage water, third stage treated, from Beni-Suef city, Egypt. Antimony tin oxide (ATO)/polyaniline (PANI)/PbI2 photoelectrode is prepared through the in situ oxidative polymerization of PANI on ATO, then PANI is used as an assistant for PbI2 deposition using the ionic adsorption deposition method. The chemical structural, morphological, electrical, and optical properties of the composite are confirmed using different analytical tools such as X-ray diffreaction (XRD), scanning electron microscope (SEM), transmision electron microscope (TEM), Fourier-transform infrared spectroscopy (FTIR), and UV-Vis spectroscopy. The prepared PbI2 inside the composite has a crystal size of 33 nm (according to the peak at 12.8°) through the XRD analyses device. SEM and TEM confirm the hexagonal PbI2 sheets embedded on the PANI nanopores surface. Moreover, the bandgap values are enhanced very much after the composite formation, in which the bandgap values for PANI and PANI/PbI2 are 3 and 2.51 eV, respectively. The application of ATO/PANI/PbI2 nanocomposite electrode for sewage splitting and H2 generation is carried out through a three-electrode cell. The measurements carreid out using the electrocehical worksattion under th Xenon lamp (100 mW.cm−2). The produced current density (Jph) is 0.095 mA.cm−2 at 100 mW.cm−2 light illumination. The photoelectrode has high reproducibility and stability, in which and the number of H2 moles is 6 µmole.h−1.cm−1. The photoelectrode response to different monochromatic light, in which the produced Jph decreases from 0.077 to 0.072 mA.cm−2 with decreasing of the wavelengths from 390 to 636 nm, respectively. These values confirms the high response of the ATO/PANI/PbI2 nanocomposite electrode for the light illuminaton and hydrogen genration under broad light region. The thermodynamic parameters: activation energy (Ea), enthalpy (ΔH*), and entropy (ΔS*) values are 7.33 kJ/mol, −4.7 kJ/mol, and 203.3 J/mol.K, respectively. The small values of ΔS* relted to the high sesnivity of the prepared elctrode for the water splitting and then the hydrogen gneration. Finally, a theoretical study was mentioned for calculation geometry, electrochemical, and thermochemistry properties of the polyaniline/PbI2 nanocomposite as compared with that for the polyaniline.

“…XRD analysis is a successful technique to determine the crystallites [ 23 , 24 , 25 , 26 ]. In particular, Munmun Basak et al used XRD to quantify the size of crystallites using several models, including the Debye Scherrer method, and verified that the determined crystallite size is very similar to the TEM (Transmission electron microscopy) result [ 23 ]. Therefore, the crystallinity of the Cu films was analyzed using XRD (PANalytical, X’pert Pro MRD, Gwangju, Korea, Cu-Kα radiation source (λ = 0.15406 nm)).…”

The mechanical properties of thin films are under-researched because of the challenges associated with conventional experimental methods. We demonstrate a technique for determining the intrinsic shear strength and strain of thin films using a nano-cutting technique based on an orthogonal cutting model with precise control of the cutting system. In this study, electroplated Cu films with thicknesses of 1.5 μm and 5 μm and a sputtered Cu film with a thickness of 130 nm were fabricated to evaluate the mechanical strength. Experiments revealed a shear strength of approximately 310 MPa with a shear strain of 1.57 for the electroplated Cu film and a shear strength of 389 MPa with a shear strain of 2.03 for the sputtered Cu film. In addition, X-ray diffraction analysis was performed to correlate the experimental results.
