Lattice fluorination-enabled programmable energetics in metastable intermolecular composites: Atomic F/O engineering and hierarchical redox control enabling instantaneous memory chip destruction Jingwei Li, Xuwen Liu, Zhangbo Ming, Yongsheng Jia, Jinshan Sun, Yingkang Yao, Quanmin Xie, Yihao Shen, Zhichao Zhao, Guangyu Yin, Sabit Tursynbek, Meruyert Nazhipkyzy, Zhandos Tauanov, Ayagoz Bakkara, Makpal Seitzhanova Defence Technology, 2026 As a prototypical high-energy-density reactive material system, metastable intermolecular composites (MICs) have attracted considerable interest owing to their customizable component configurations and interfacial architectures. Nevertheless, their energy release characteristics are fundamentally constrained by the formation of condensed-phase products with elevated boiling points, thereby diminishing their efficacy in applications requiring rapid pressure generation or shock wave propagation. Herein, we demonstrate a molecular-level fluorination approach that enables oxygen substitution by fluorine within bismuth oxide crystalline frameworks, yielding ternary Bi x O y F z crystals with atomically precise F/O stoichiometric control through systematic solvent polarity engineering. This energetics system, designed through a multilevel regulation strategy, realizes stepwise redox reactions of Al-F and Al-O during energy release, with the partitioning between these redox pathways being precisely allocable through hierarchical regulation. Furthermore, the pre-ignition reaction (PIR) between Bi x O y F z and Al 2 O 3 (the inert passivation shell of Al) weakens the passivation layer, lowering the ignition threshold. The in situ generation of low-boiling-point AlF 3 promotes rapid gas expansion, leading to significantly enhanced pressurization rates and deflagration wave velocities under confinement compared to conventional strategies. To evaluate energy output capabilities and validate potential safety-protection applications, the system successfully achieved instantaneous destruction of SD chips, enabling secure data erasure. This work establishes crystalline lattice fluorination as a generalized materials design strategy to transcend intrinsic limitations of MICs systems in component selection and reaction thermodynamics, providing new paradigms for adaptive energetic architectures and transient microelectromechanical applications.

Study and development of the components of gas generator compositions based on the ammonium nitrate to improve blasting operations safety D.A. Bayseytov, , M.I. Tulepov, Zh.A. Amir, A.Ye. Orazbayev, S. Tursynbek, , , , and Bezopasnost Truda V Promyshlennosti, 2021 The article is devoted to the study and development of the components of gas generator compositions based on the ammonium nitrate to improve safety of blasting operations. This is primarily due to the low cost of ammonium nitrate, low sensitivity to mechanical and detonation effects and a significantly lower content of harmful compounds in the combustion products compared to the analogues. PA-4 aluminum powder was used as fuel, carbon black powder — as a gas-forming agent. The effect was studied concerning different amounts of aluminum powder on the combustion characteristics of a gas generator composition based on the ammonium nitrate. Calculated and experimental data showed that it is unreasonable to introduce more than 5 % of aluminum into the composition. According to the results of the conducted study, a gas generator composition based on the ammonium nitrate was developed to increase blasting operations efficiency and safety. Laboratory and polygon studies confirmed the efficiency and safety of using gas generator compositions at the destruction of stone. Destruction of the stone occurred without scattering of individual fragments, formation, and propagation of an air shock wave. Thus, the urgent task is to ensure blasting operations safety using gas generator compositions, which will allow to eliminate the formation of harmful, toxic gases and the high explosive effect.
Combustion Study of Gas-Generating Compositions with Carbon Powder Additives S. Tursynbek, V. E. Zarko, O. G. Glotov, A. B. Kiskin, M. A. Korchagin, Z. A. Mansurov, G. S. Surodin, K. A. Umbetkaliev Russian Journal of Physical Chemistry B, 2020 In blasting in dense urban areas and piece stone mining, the issue of organizing gentle destruction modes arises, which requires the use of pyrotechnic compositions operating in the deflagration mode. In such compositions, ammonium perchlorate, ammonium nitrate, and other nitrates are used as oxidizing agents. Magnesium is often used as fuel. In this paper, the combustion of a three-component mixture of sodium nitrate, magnesium, and carbon was studied. The latter was obtained by carbonizing a walnut shell or grinding gas mask adsorbents. The thermodynamic calculations of combustion were performed, and the combustion characteristics of the NaNO3/Mg/C mixture with a component ratio of 60/20/20 were measured.

Dalton Rasayan Journal of Chemistry, 2017 The purpose of this study is the development and investigation of gas-generating composition based on potassium chlorate for the destruction of a stone. The thermodynamic analysis of the energy characteristics of the studied gasgenerating compositions was carried out. Influence of various amounts of nano-aluminium on features and regularities of burning and ignition of pyrotechnic gas-generating composition on the basis of potassium chlorate was studied. By results of thermodynamic calculation and experimental work the optimum gas-generating composition for destruction of a stone KClO3-72 %, polyethylene -17%, nano aluminium Alex-11% was chosen. The carried-out polygon tests on the destruction of a stone had shown high efficiency of use of this gas-generating composition for destruction of a stone.
