Summary: This paper focuses on the pyrolysis behavior of 5-amino-1 H-tetrazole (5AT) and investigates the catalytic effects of nitrocellulose (NC) and potassium nitrate (KNO3) on the thermal decomposition mechanism and kinetics behavior of 5AT. The results suggest that adding NC simplifies the degradation process of 5AT and KNO3 decreases the activation energy and changes the reaction model. These findings provide valuable guidance for improving the design of environmentally friendly pyrotechnics.

Summary: In this study, M-x-MoO3-alpha-NaFe2(MoO4)(3)-alpha-FeMoO4 nanomaterials were synthesized by the hydrothermal method. Characterization and analysis of the synthesized samples were performed using XRPD, FESEM, TEM, BET-BJH, UV-Vis, and VSM. Rietveld analysis revealed the presence of alpha-NaFe2(MoO4)(3), alpha-FeMoO4, MoO3, and Fe2O3 crystal phases. UV-Vis spectra showed a small direct band gap energy in the range of 1.3-1.5 eV. VSM analysis confirmed the magnetic properties of the samples, with Ni doping resulting in ferromagnetic behavior. Catalytic synthesis of 5-aryl-1H-tetrazole analogs was successfully performed under various conditions, with ethyl alcohol as the most efficient solvent.

Summary: This study investigates the pyrolysis behaviors of 5-Amino-1H-Tetrazole (5AT) and the effects of different modification methods on its combustion properties. The results show that boron powder and copper powder have different catalytic effects on the decomposition of 5AT at different stages. The solution recrystallization method exhibits better modification effect in the later stages, while copper powder shows a stronger catalytic effect compared to boron powder. These findings provide valuable guidance for the understanding and applications of 5AT-based propellants.

Summary: The performance of 5-phenyl-1H-tetrazole (PTAH) and 5-(4-pyridyl)-1H-tetrazole (PyTAH) as corrosion inhibitors on copper and commercial brass in simulated seawater containing 3.5% NaCl was investigated. The results showed that PTAH exhibited better corrosion inhibition efficiency with 97% for copper and approximately 96% for brass at an optimal concentration of 0.01 M. Surface investigations revealed that the presence of PTAH significantly protected the copper and brass surfaces. The Langmuir adsorption isotherm indicated physiochemical adsorption of the inhibitors on the sample surfaces, while the Arrhenius plot demonstrated an increase in corrosion reaction activation energy after the addition of the inhibitor, indicating its inhibitive effect on copper and brass surfaces.

Summary: This paper investigates the catalytic effects of different types of oxidizers on 5-Amino-1H-tetrazole (5AT). The thermal behavior and activation energy of 5AT are analyzed using TG-DSC test and Kissinger/Ozawa methods. The experimental results show that 5AT-AN has the lowest activation energy and the degradation process is simplified into one step. The addition of AP, NaClO4, and MnO2 can promote the pyrolysis process of 5AT, while Cr2O3 mainly acts as a catalyst above 400 degrees C without oxidation. The catalytic mechanism of Cr2O3 mainly involves polyaddition and ring-opening reactions of N-containing heterocycles. These findings offer valuable guidance for understanding, designing, and using 5AT-based propellants.
