On the basis of a design strategy that results in the assembly of diverse N–O building blocks leading to energetic materials, 3,3′-dinitroamino-4,4′-azoxyfurazan and its nitrogen-rich salts were obtained and fully characterized via spectral and elemental analyses. Oxone (potassium peroxomonosulfate) is an efficient oxidizing agent for introducing the azoxy N-oxide functionality into the furazan backbone, giving a straightforward and low-cost synthetic route. On the basis of heats of formation calculated with Gaussian 03 and combined with experimentally determined densities, energetic properties (detonation velocity, pressure and specific impulse) were obtained using the EXPLO v6.01 program. These new molecules exhibit high density, moderate to good thermal stability, acceptable impact and friction sensitivities, and excellent detonation properties, which suggest potential applications as energetic materials. Interestingly, 3,3′-dinitroamino-4,4′-azoxyfurazan (4) has the highest calculated crystal density ...

3,3′-Dinitroamino-4,4′-azoxyfurazan and Its Derivatives: An Assembly of Diverse N–O Building Blocks for High-Performance Energetic Materials

In this review, we document the most recent developments in azo-linked heteroaromatic (imidazole, pyrazole, triazole, triazine, tetrazine and oxadiazole) high-nitrogen energetic materials and their salts. In this account, a wide range of azo materials such as coordination polymers and metal–organics are also included. The synthesis of these azo based compounds, their physical and explosive properties are presented. These energetic compounds generally exhibit desirable properties and performance, which in some cases are superior to those of the common energetic materials RDX, TNT, and TATB.

Azo-linked high-nitrogen energetic materials

The straightforward synthesis and energetic properties of a new class of energetic materials, 1,2,3-triazolo- [4,5-e]furazano[3,4-b]pyrazine 6-oxide and its energetic salts are described. They were characterized by IR and multinuclear NMR spectroscopy, elemental analysis, differential scanning calorimetry, and single-crystal X-ray diffraction are given. The X-ray structures show that in the title compound, the hydrogen atom is bonded to the nitrogen in the pyrazine ring; however, in the salts, the negative charge is associated with the triazole nitrogen. Heats of formation for all compounds were calculated with the G2 method and then combined with experimentally determined densities to obtain detonation pressures (P) and velocities (D) by using EXPLO5 program. These new materials exhibit good densities and thermal stabilities, high heats of formation, acceptable detonation properties, and are insensitive to impact.

1,2,3-Triazolo[4,5,-e]furazano[3,4,-b]pyrazine 6-oxide--a fused heterocycle with a roving hydrogen forms a new class of insensitive energetic materials.

Synthesis and Crystal Structure of Bis-3,3'-(nitro-NNO-azoxy)-4,4'-azofurazan

Revealing alkali metal ions transport mechanism in the atomic channels of Au@α-MnO2

Background Osteosarcoma is a common bone sarcoma that occurs in childhood and adolescence. Although research on non-coding RNAs (ncRNAs) of osteosarcoma has been developed rapidly in recent years, a specific bibliometric analysis on this topic has not yet been performed. The bibliometric analysis aims to summarize knowledge atlas, research hotspots, and emerging trends and to provide researchers with new perspectives in further studies. Methods All publications regarding ncRNAs of osteosarcoma published from 2000 to 2021 were retrieved from the Web of Science Core Collection. Quantitative indicators including the number of publications and citations, H-index, and journal citation reports were analyzed by using Excel 2019 and R software. VOSviewer and CiteSpace were used to analyze the cooperation among countries/institutions/journals/authors and the co-occurrence of keywords, keywords bursts, and references. Results A total of 3206 publications were extracted. A significant growth trend in the annual number of publications over the past 22 years is revealed (R 2 = 0.999). The most prolific country and institution were China (2260) and Shanghai Jiao Tong University (134), respectively. Professors Wang W and Liu W contributed the most to this field. The keywords were stratified into six clusters: Cluster 1 (apoptosis and growth), Cluster 2 (cancer and progression), Cluster 3 (microRNAs and downregulation), Cluster 4 (genes and differentiation), Cluster 5 (expression and biological functions), and Cluster 6 (metastasis). The long non-coding RNAs and circular RNAs have been considered as an important research hotspot in the near future. Conclusion This study offers a scientific perspective on ncRNAs of osteosarcoma and provides researchers with valuable information to understand the knowledge structure and to identify emerging trends in this field.
