ABSTRACT Nitrocellulose (NC) is a highly energetic material used in various military and civilian applications. Nevertheless, the inherent instability of NC poses safety storage lifetimes challenges. To address this issue, traditional stabilizers have been to improve thermal stability NC. In study, we investigate effectiveness novel hybrid enhancing We prepared series samples supplemented with different stabilizers, including combinations Of 2‐nitrodiphenylamine (2‐NDPA) along cobalt (Co), nickel (Ni), manganese (Mn) ion‐exchanged sodium mordenite (NaMOR) zeolite. The underwent structural characterizations study their chemical compatibility structures. Furthermore, behavior were assessed using range analytical techniques, C80 microcalorimetry, thermogravimetric analysis (TGA), standardized tests like methyl violet (MV), vacuum stability, Bergmann–Junk (B&J) protocols. Experimental results confirmed good between stabilizer components matrix. Results from TGA microcalorimetry demonstrated that combining 2‐NDPA ion‐exchange NaMOR has synergistic effect. This combination not only enhances but also reduces its rate degradation compared alone. Additionally, accelerated aging emphasized systems, demonstrating ability scavenge nitroxide radicals mitigate harmful effects free produced during pyrolysis Thermo‐kinetic clearly indicated significant increase activation energy ( E ) pre‐exponential factor (log( A )) after addition designed stabilizers. Compared pristine NC, increased by substantial margin 37–74 kJ/mol, whereas log( rose 4.2–8.3 s −1 , indicating enhanced slower decomposition. research highlights potential as viable alternative for paving way development safer more effective nitrate ester‐based materials (NEEMs).

The study involved the synthesis of magnetite (Fe3O4) and zeolite-supported Fe3O4 (Fe/Z) using co-precipitation (COP) hydrothermal (HYD) methods which proved effective for removing Cr(vi) from contaminated water. X-ray diffraction (XRD) analysis showed that phase had a cubic crystal structure. COP method resulted in lower crystallinity compared to HYD method. different preparation also led variations morphologies sizes particles. HYD-prepared sample exhibited uniform spherical shape with 400-500 nm, while COP-prepared samples rod-like granule shapes smaller particle 20-50 nm. investigated adsorption ability reducibility on adsorbents. It was found crystallinity, shapes, significantly influenced capacity stability Cr-adsorbed species. Additionally, this work demonstrated zeolite supports enhanced capabilities Fe3O4, particularly samples, achieving an 2.33 mg per g Fe by creating stable photoelectron spectroscopy (XPS) absorption (XAS) confirmed Cr species adsorbed Fe/Z_HYD, identifying ion-exchange lattice structures Fe3-x x O4 Fe1-x CrOOH as most forms. This provides insights into potential Fe3O4/ZSM-5 remediation.
