“…The results of the XRD analysis showed that there was a difference in the interplanar distances and the relative intensity of the eutectic and its respective pure components, indicating that the studied eutectic was a mechanical system [23]. The variation reflected in the diffraction peaks of the eutectic mixture could be explained by the existence of weak molecular interactions between the eutectic components [25, 32].…”

“…Compatibility can be defined as the aptitude of materials to preserve their physical and chemical properties when mixed together, even after long storage periods; it is an important safety aspect related to their production, use and storage and needs to be investigated. The compatibility of raw materials will be studied by Fourier transform infrared (FTIR) spectroscopy, X‐ray diffraction (XRD) [24, 25], and X‐ray photoelectron spectroscopy (XPS). Construction of the binary phase diagram from visual measurements and cooling curves has traditionally been used.…”

In this article, a eutectic mixture was prepared by mixing 1‐methyl‐3,4,5‐trinitropyrazole (MTNP) and pentaerythritol tetranitrate (PETN) by a new method. The T−X phase diagram and H−X phase diagram were obtained by means of DSC analysis, and then the ratio of the eutectic was obtained. All systems displayed simple eutectic behavior. Energy‐dispersive X‐ray spectroscopy (EDS), X‐ray diffraction (XRD), Fourier transform infrared (IR) spectroscopy, and X‐ray photoelectron spectroscopy (XPS) were performed to characterize the structure of the eutectic. Thermodynamic analysis and TG‐MS tests were carried out to explore the thermal decomposition of the eutectic. Then, the mechanical sensitivity and thermal sensitivity of the raw materials and the eutectic were tested, and the detonation performance was also calculated. The results show that the compatibility of the components of the eutectic is not perfect because of the intermolecular forces between the raw materials. Thermal the decomposition products are mainly H2, H2O, N2, CO, NO, N2O and CO2 and a small amount of CH4. The eutectic has the characteristics of high energy and insensitivity and is expected to replace TNT‐based molten cast explosives.

“…Hence, tailoring the thermal decomposition of NC allows tuning the combustion properties of propellants containing NC. On the other hand, NC-based formulations can exhibit a low thermal stability because of the rupture of O–NO 2 of NC even at ordinary conditions, which can cause the deterioration of their prominent characteristics and subsequently restrain their performance and safe and reliable service-life [ 6 , 7 ]. This situation can be prevented by incorporating either stabilizers or other additives.…”

In this study, carbon mesospheres (CMS) and iron oxide nanoparticles decorated on carbon mesospheres (Fe2O3-CMS) were effectively synthesized by a direct and simple hydrothermal approach. α-Fe2O3 nanoparticles have been successfully dispersed in situ on a CMS surface. The nanoparticles obtained have been characterized by employing different analytical techniques encompassing Fourier transform infrared (FTIR) spectroscopy, Raman spectroscopy, X-ray diffraction (XRD) and scanning electron microscopy (SEM). The produced carbon mesospheres, mostly spherical in shape, exhibited an average size of 334.5 nm, whereas that of Fe2O3 supported on CMS is at around 80 nm. The catalytic effect of the nanocatalyst on the thermal behavior of cellulose nitrate (NC) was investigated by utilizing differential scanning calorimetry (DSC). The determination of kinetic parameters has been carried out using four isoconversional kinetic methods based on DSC data obtained at various heating rates. It is demonstrated that Fe2O3-CMS have a minor influence on the decomposition temperature of NC, while a noticeable diminution of the activation energy is acquired. In contrast, pure CMS have a slight stabilizing effect with an increase of apparent activation energy. Furthermore, the decomposition reaction mechanism of NC is affected by the introduction of the nano-catalyst. Lastly, we can infer that Fe2O3-CMS may be securely employed as an effective catalyst for the thermal decomposition of NC.

The exploration of curing process of benzoxazine resins, which possess outstanding features, is crucial for practical and advanced applications. In this study, bisphenol A-aniline based benzoxazine (BA-a) composites reinforced with alkali treated alfa fibers (TAF) were prepared. The influence of different loadings of the TAF on the curing kinetics of BA-a was investigated using non-isothermal differential scanning calorimetry (DSC) at different heating rates. Isoconversional integral methods or model free kinetics, namely, the iterative Kissinger-Akahira-Sunose (it-KAS), iterative Flynn-Wall-Ozawa (it-FWO), Sbirrazzuoli methodology (VYA/CE) and Trache-Abdelaziz-Siwa-ni (TAS) methods have been applied to the experimental data in order to evaluate the curing kinetic parameters. The study revealed that the presence of TAF improved the crosslinking reaction of benzoxazine and reduced the activation energy. The pre-exponential factor exhibited the same trend as the activation energy. The reaction model, examined for all composites, showed that all systems were accurately presented by an autocatalytic reaction model. The Avrami-Erofeev model was the most appropriate for describing the cure kinetics and revealed a good agreement with experimental data.
