Energetic materials possessing high energy content, exceptional heat resistance, and insensitivity have long been recognized as a significant and prominent subject of academic debate. In this study, the necessity for high-energy explosives in both military and civilian domains prompted the introduction of the concept of an “energetic negative-burning rate catalyst” in heat-resistant and insensitive energetic materials. Therefore, a typical and effective catalyst(ZIF-90) was discovered. ZIF-90, which can be easily synthesized and features a large specific surface area and regular pore structure, contributes to molecular-scale changes in the pyrolysis process of energetic materials. Additionally, the presence of surface aldehyde groups facilitates the partial absorption of heat,thereby collectively contributing to the augmentation of pyrolysis peak temperatures for seven distinct energetic materials(RDX, HMX, CL-20, LLM-105, LLM-126, Al H3, and DAP-4). Specifically, the pyrolysis peak temperatures were elevated by 6.6°C, 1.7°C, 1.6°C, 6.4°C, 1.4°C, 13.1°C, and 7.0°C, respectively. Moreover, the highly stable ZIF-90, functioning as an intrinsically insensitive Energetic Metal-Organic Framework(EMOF), not only effectively mitigates the sensitivity of energetic materials but also ensures minimal energy loss. Notably, the incorporation of a mere 5 wt% of ZIF-90 resulted in a significant enhancement of over one-fold in the heat resistance of LLM-105-based explosive cylinders, thereby validating the practical applicability of ZIF-90 in energetic materials. Moreover, the efficacy of ZIF-90 in solid propellant formulations was corroborated through flame experiments conducted on solid propellants. The development of such a pragmatic and universally applicable energetic negative-burning rate catalyst presents a promising strategy for the future advancement of highperformance, heat-resistant, and insensitive energetic materials.

背景单纯通过X线诊断SchatzkerⅢ型胫骨平台骨折易发生漏诊,我们定义了一个新的角度(应力分散角)并探索了这个角度和SchatzkerⅡ、Ⅲ型骨折的相关性以求帮助减少SchatzkerⅢ型胫骨平台骨折的漏诊。方法回顾性分析河北医科大学第三医院2015年12月至2022年10月收治的符合纳入标准的胫骨平台骨折患者145例(SchatzkerⅡ型105例,SchatzkerⅢ型40例),SchatzkerⅡ型组男51例,女54例,平均年龄(46.08±1.53)岁;SchatzkerⅢ型组男21例,女19例,平均年龄(50.10±2.09)岁。定义胫骨中线和胫骨平台外侧缘切线之间的角度为应力分散角,通过X线测量应力分散角。统计比较SchatzkerⅡ型组和SchatzkerⅢ型组的性别、年龄、BMI、术前合并症、致伤原因、应力分散角的差异。应用Logistic回归分析对结果进行检验。结果SchatzkerⅢ型组的应力分散角(47.85±0.62)°大于SchatzkerⅡ型组(37.38±0.38)°,差异有统计学意义(P0.05)。将单因素分析中P<0.2的3个变量(年龄、致伤原因、应力分散角)与SchatzkerⅡ、Ⅲ型胫骨平台骨折进行Logistic回归分析。Logistic回归分析证明只有应力分散角是SchatzkerⅡ、Ⅲ型胫骨平台骨折的独立影响因素。结论应力分散角是SchatzkerⅢ型胫骨平台骨折的影响因素,诊治应力分散角较大的膝关节外伤患者时,建议行膝关节CT检查,避免漏诊的发生。

The structures, infrared spectra and cation stability of seven 5,5′-azotetrazolate nonmetallic salts are investigated by using B3LYP method with 6-311+G (d) basis set. The salts are guanidinium (GZT), aminoguanidinium (AGZT), diaminoguanidinium (DAGZT), triaminoguanidinium (TAGZT), azidoformamidinium (AFZT), ammonium (AZT), and hydrazinium (HZT), respectively. The calculated results indicate that the carbon and nitrogen atoms of the cations in seven nonmetallic salts are characterized to be sp2 hybrid atoms, and the ranges of characteristic absorption peaks in IR spectra of the seven nonmetallic salts are approximative consistent. All their cations are stable and their stabilities decrease with the increase in their nitrogen contents.
