“…The phase study of the annealed samples was carried out via utilizing the X-ray diffraction (XRD) and diffractometer (Siemens, D5000) with Cu K α radiation at room temperature. In this study, the mean crystalline size of the powders was estimated by the X-ray broadening approach by employing Scherer's formula as follows [15]:…”

This paper has investigated the absorption properties of multi-layer BaFe 12 O 19/ epoxy composites. Various Ba-ferrites were synthesized by the co-precipitation method followed by high-energy ball milling for the homogenizing and milling purposes. The microstructural, structural, loss-related behavior and magnetic properties were examined by the X-ray diffractometer, field-emission scanning electron spectroscope, network analyzer, and vibrating-sample magnetometer, respectively. The material indicated an enhancement in the saturation magnetization from 35.45 to 57.83 emu/g by increasing the heat-treating temperature (HT). The effects of the type and number of layers on microwave absorption behavior were obtained from the X-range (8 to 12 GHz). The ferromagnetic resonance and transmit-line theories were also employed to analyze these factors on the microwave absorption. These microwave absorbers were modeled and simulated by MATLAB. The simulations were carried out from 8 to 12 GHz to analyze the absorbers performance. Based upon these theories and experimental data, the microwave absorption can be altered solely by changing the materials between the layers. For instance, the maximum peak was increased from − 3 to − 15 dB by altering the as-synthesized ferrite powders to the completed ferrite powders (BaFe 12 O 19). Moreover, there was a sufficient match between experimental data and theoretical results.

“…This shows that sample prepared from 20 wt % annealed at 500 ℃ with higher intensity peak corresponding to (101) has larger crystallite size than the 15 wt % prepared sample annealed at 450 ℃ . The average crystallite size was estimated using Scherer's equation, in equation 2, to the major peaks of the XRD data and taking an average [29].…”

Concentrations in weight percent (5- 25 wt %) of TiO2 films used to optimize the film formation. The TiO2 films on glass substrates successfully obtained by spin-coating process using TiO2 nanopowder as precursor. Ultraviolet-Visible (UV-Vis), Scanning Electron Microscopy (SEM) equipped with Electron Diffraction X-ray (EDX) and X-ray Diffractometer (XRD) techniques used to characterize the films. The result of electron transport material (TiO2) showed that film prepared from 15 wt % of TiO2 solution and annealed at 450 has highest transmittance at visible light region with indirect optical band gap of 3.24 eV which corresponds to wavelength of 382 nm whereas 20 wt % has indirect band gap of 2.99 nm equivalent to 414.7 nm . The chemical analysis from Electron Diffraction Spectroscopy (EDS) of the material shows titanium and oxygen present at L and K-shells, respectively. The sample crystallized with preferred orientation at (101) from XRD analysis.

In the last few decades, there has been a trend involving the use of nanoscale fillers in a variety of applications. Significant improvements have been achieved in the areas of their preparation and further applications (e.g., in industry, agriculture, and medicine). One of these promising materials is magnesium oxide (MgO), the unique properties of which make it a suitable candidate for use in a wide range of applications. Generally, MgO is a white, hygroscopic solid mineral, and its lattice consists of Mg2+ ions and O2− ions. Nanostructured MgO can be prepared through different chemical (bottom-up approach) or physical (top-down approach) routes. The required resultant properties (e.g., bandgap, crystallite size, and shape) can be achieved depending on the reaction conditions, basic starting materials, or their concentrations. In addition to its unique material properties, MgO is also potentially of interest due to its nontoxicity and environmental friendliness, which allow it to be widely used in medicine and biotechnological applications.
