Summary: This study investigates the effects of nanosized barium oxide (BaO) on the thermal decomposition kinetics and chemical stability of nitrocellulose. BaO nanoparticles were synthesized and combined with nitrocellulose. The prepared BaO nanoparticles and NC-based composites were characterized using spectroscopic, microscopic, and thermal analysis techniques. Differential scanning calorimetry tests and various isoconversional kinetic approaches were used to understand the thermal decomposition kinetics of the NC-based composite. Qualitative and quantitative stability tests were conducted to investigate the impact of BaO nanoparticles on the chemical stability of NC. The results show that the addition of nano barium oxide enhances both the thermal and chemical stabilities of nitrocellulose.

Summary: The stereoselective preparation of fullerene bis-adducts through nontethered methods is challenging due to the production of significant amount of regioisomers. The trans-4 aziridino[60]fullerenes were selectively synthesized without a catalyst by reacting octabromofullerene with corresponding aniline. Characterization through NMR, UV-vis spectroscopy, and X-ray analysis was provided. The possible synthesis process of highly regioselective trans-4-bisaziridino[60]fullerenes was proposed along with exploring their potential application as propellant stabilizers.

Summary: In the past decade, the scientific community has extensively studied the decomposition of ammonium perchlorate (AP). This research aims to investigate the effect of nanothermite on the thermal decomposition of AP. MgAl-PTFE nanothermite was mechanically activated through arrested reactive milling, coated with potassium perchlorate (KP), and characterized. The results showed that the phase compositions remained unchanged and the presence of nanothermites promoted the thermal decomposition process of AP by reducing the activation energy by about 6%.

Summary: This study aims to evaluate the potential of a hybrid filler composed of alpha fibers and graphene nanoplatelets (AFGNPs) at different ratios on the properties of poly(epsilon-caprolactone) (PCL) matrix. The composites prepared by mold casting exhibited improved thermal behavior compared to pure PCL, with the sample containing 5% filler showing the highest thermal stability. Moreover, the incorporation of 5% (AF-GNPs) resulted in an increase in the tensile strength of PCL from 13.23 to 14.18 MPa, along with an enhancement in Young's Modulus from 248.75 to 431.15 MPa. These composites offer an environmentally friendly alternative to conventional, petroleum-based, and non-renewable composites for various applications.

Summary: High-substitute nitrochitosan (NCS) was synthesized via esterification of chitosan, and its characteristics were thoroughly investigated. FTIR and SEM analyses were used to scrutinize the chemical functionalities and morphological features of chitosan and its nitrated derivative. TGA and DSC thermal characterizations revealed that NCS undergoes two consecutive exothermic processes, involving the thermolysis of explosophoric functional groups accompanied by the thermo-oxidative degradation of the polymeric framework. Moreover, hyphenated TGA-FTIR characterization identified NO, NO2, CO2, H2O, CH4, HCN, and CH2O as the main evolved products during NCS decomposition.

Summary: This study investigates the stability and thermo-kinetic properties of double base nitrocellulose (NC)/diethylene glycol dinitrate (DEGDN) propellant with the addition of Kraft lignin. The results show that lignin can effectively stabilize the NC/DEGDN composite, similar to conventional stabilizers. Furthermore, thermal analysis indicates that the addition of 2-NDPA, C-II, and lignin improves the thermal decomposition temperature of NC/DEGDN propellant. These findings contribute to the development of environmentally friendly stabilizers for nitrate ester-based composites.
