Transition group metal catalysts showing atomic dispersion are on the rise as affordable electrocatalysts for oxygen reduction reaction (ORR) in fuel cell batteries, but their activity acidic media remains constrained.
More nitro groups accord benzenes with higher energy but lower chemical stability. Hexanitrobenzene (HNB) a fully nitrated structure has stood as the peak of organic explosives since 1966, it is very unstable and even decomposes in moist air. To increase limit strike balance between stability, we propose an interval full-nitro-nitroamino cooperative strategy to present new benzene, 1,3,5-trinitro-2,4,6-trinitroaminobenzene (TNTNB), which was synthesized using acylation-activation-nitration...
Tetranitroamino HEDMs based on bis-triazole with comparable performance to CL-20 (<italic>D</italic>: 9421 and 9609 m s<sup>−1</sup>) superior stability.
Energetic materials, which are comprised of four oxadiazole rings and linked by three different bridges ([–NH–NH–], [–NN–], [–NN(O)–]) developed.
The first two examples of ECP-based primary explosives exhibiting a positive oxygen balance (based on CO<sub>2</sub>), [Ag<sub>5</sub>NT<sub>4</sub>NO<sub>3</sub>]<sub>n</sub> and [Ag<sub>5</sub>NT<sub>4</sub>ClO<sub>4</sub>]<sub>n</sub>, are presented.
The first case of a decrease in density with the introduction trinitromethyl group.
Full nitration is one of the most effective strategies used in synthesizing high-density energetic materials, but this strategy has reached its limit because resultant compounds cannot be further functionalized. To overcome limitation, we present synergistic action full and strong intermolecular H-bonding designing 1-trinitromethyl-3,5-dinitro-4-nitroaminopyrazole (DNTP) with a density that exceeds those reported monocyclic CHON compounds. The detonation velocity specific impulse DNTP exceed...
In this study, we propose a "modular assembly" strategy to synthesize series of new trinitromethyl high-energy molecules. For typical molecule 1, approach reduces the number synthetic steps from 7 2 and improves yield 1.0% 48.3%, representing more than 48-fold increase compared traditional "skeleton first, group later" method. All synthesized molecules exhibit exceptional energetic performance, with 1 demonstrating density 1.913 g cm–3, detonation velocity 9151 m s–1, thermal decomposition...
In order to explore the mechanism responsible for interactions in surfactant-polymer composite flooding and broaden application range of binary system heterogeneous oil reservoirs, this paper, influences different surfactants on viscosity two polymers with similar molecular weights, partially hydrolyzed polyacrylamide (HPAM) hydrophobically modified (HMPAM), were studied at reservoir environments. addition, relationship between synergistic effects displacement efficiency was also...
Coordination polymers (CPs) consisting of alkali metals (Na, K, Rb, and Cs) a powerful nitrogen- oxygen-rich energetic ligand (4,4'-bis(dinitromethyl)-3,3'-bisnitramide-methylene-furazanate, DBMF2- ) were developed. Molecular structures these CPs, confirmed by single-crystal X-ray diffraction analysis, indicated that the same takes on U-shaped state for Na an N-shaped Cs. Explosion tests demonstrated both Na2 DBMF K2 efficiently detonated secondary explosive RDX. This indicates they are...
Abstract Despite the synthesis of numerous cationic metal‐organic frameworks (CMOFs), their counter anions have been primarily limited to inorganic Cl − , NO 3 ClO 4 BF and Cr 2 O 7 2− which weak coordination abilities. In this study, a series new CMOFs is synthesized using azolates with strong abilities as anions, are exclusively employed ligands for coordinating metals. Owing unique nitrogen‐rich composition azolates, demonstrate significant potential high‐energy‐density materials....
It is desirable to consider the molecular design and crystal configuration in research of energetic materials. We discovered an interesting layer stacking configuration, which different from previous 2D-plane stacking, termed it as "3D-cube stacking". This new resulting unusual U-shaped structures vast H-bonding interactions, breaks through limitations planar stacking. Compound 4, features such characteristics, exhibits excellent performance (D: 9043 m s–1; P: 35.6 GPa) acceptable...

Furazan has rarely been used as a building block in the development of energetic cations. In this study, polyamino-substituted furazan-triazole was explored an cation for synthesis salts 3–6. All new compounds were characterized by infrared and NMR spectroscopy, elemental analysis, single crystal X-ray diffraction.
