“…e DSC curve has one endothermic peak at 660°C where maximum weight loss occurs which implies phase transition of Mg (OH) 2 to MgO. Hence, the pure MgO nanoparticles have obtained with pure phase at 700°C and the obtained results are well consistent with previous reports [79,[81][82][83][84][85][86][87].…”

The magnesium oxide nanoparticles (MgO NPs) were prepared from Moringa oleifera leaf extract. Phytochemicals are derived from plant extract which are served as stabilizing and capping agents. This green route has been attracted owing to speed, reliable, and eco-friendly and cost-effective one. The synthesized magnesium oxide nanoparticles were taken into three different calcination temperatures (500, 600, and 700°C). The powder X-ray diffraction (PXRD) study shows a pure phase of face-centered cubic structure. Periclase MgO nanoparticles were prepared. The optical band gap of MgO nanoparticles is 4.5 eV, and its absorption in the UV region was observed by UV-visible spectroscopy (UV-Vis). Photoluminescence spectra have exhibited multicolor emissions were being at UV and visible region due to defect centers (F centers) of MgO nanoparticles. EDX (energy dispersive X-ray spectrum) has given the stoichiometric ratio of Mg and O. The functional groups have been studied by Fourier transformed infrared spectroscopy (FTIR), surface morphology transformation has been identified by scanning electron microscopy (SEM) studies, and VSM measurements have given the information of diamagnetic nature of MgO nanoparticles. H-R TEM micrographs have confirmed that particles were in nanorange matched with XRD report. Polycrystalline nature has been observed pattern information. TG-DSC characterization revealed phase transition and weight loss information. D-band and G-band of MgO nanoparticles are studied by micro-Raman analysis. Dielectric analysis has proven that MgO nanoparticles will be a promising candidate for linear dielectric ceramics, thermistor. The present resent studies have revealed that MgO powder will be an economical and promising candidate in superconductor, optoelectronic device, and energy storage applications.

“…Comparing the obtained values of kinetic factors for the inspected samples by both methods proven that both methodologies spectacle comparable trend and proposed analogous values for the activation energies of the inspected samples. Correspondingly, thermodynamic issues associated with the activation of the decay reaction might be attained using of the succeeding equations [53][54][55]:…”

Nanoparticles (NPs) of lead tetroxide (Pb3O4) with the spherical morphology were manufactured by the reaction of lead nitrate with sodium hydroxide, while the nanoparticles (NPs) of red iron oxide (Fe2O3) with similar morphology were fabricated by hydrothermal route in the presence of ferric chloride hexahydrate as the precursor. Evaluation of the chemical structure, the purity and the morphology of the manufactured Fe2O3 and Pb3O4 NPs was carried out by analysis via X-ray diffraction (XRD) as well as scanning electron microscope (SEM). The outcomes of XRD recognized establishment of the desired oxides, wherever the SEM images clearly exhibited the morphology of the manufactured Pb3O4 and Fe2O3 as the spherical NPs with an average particle sizes of near to 40 and 46 nm, respectively. The catalytic effect of the metallic oxide NPs on the perfection of ammonium perchlorate (AP) thermal decomposing was established by testing their AP nano-composites via differential scanning calorimetric (DSC) together with thermogravimetric analysis (TG). Thermal behavior studies displayed that adding of 5% Fe2O3/Pb3O4 NPs (as the mixture) delivers a concerned catalytic effect during AP thermal decomposition. Additionally, thermal decomposition of AP could be amended by adding of 2% Pb3O4 NPs. Further comparison of the NPs catalytic effects was obtained by computing the values of activation energies (E) and thermodynamic parameters (i.e., ΔS#, ΔH# and ΔG#) for their thermal decomposition by non-isothermal approaches.

The copper oxide nanoparticles (nano‐CuO)/nitrocellulose (NC)/triethyleneglycol dinitrate (TEGDN)/diaminoglyoxime (DAG) nanocomposites were successfully prepared as a convenient propellants. The catalytic effect of nano‐CuO on the thermal behavior and the decomposition kinetics of the samples were precisely verified via thermogravimetry (TGA) and differential scanning calorimetry (DSC). The CuO nanoparticles significantly altered the thermal pattern of the studied energetic materials, e. g., the temperatures corresponded to the DSC peaks were changed by increasing the nano‐CuO amount. Moreover, the catalyst resulted in the decrement in the activation energy of the decomposition stage by ∼30–50 kJ mol−1 and also improved the thermal stability of TEGDN/NC/DAG composite. The thermokinetic and thermodynamic parameters of the energetic nanocomposites were explained by using the Kissinger and Starink differential methods and the integral methods of Coats Redfern and Flynn‐Wall‐Ozawa. The mechanism function and the kinetic equation of the main exothermal decomposition step for the parent composite was found to be different from that of the 1–3 % CuO‐contained nanocomposites.
