Article Abstract
N-nitration of 2,6-diamino-3,5-dinitropyrazine (ANPZ) leads to a sensitive energetic compound N,N'-(3,5-dinitropyrazine-2,6-diyl)dinitramide. This nitro(nitroamino) compound was stabilized by synthesizing energetic salts, dipotassium (3,5-dinitropyrazine-2,6-diyl)bis(nitroamide) () and diammonium (3,5-dinitropyrazine-2,6-diyl)bis(nitroamide) (). Compounds and are fully characterized by single-crystal X-ray diffraction. Compound exhibits a three-dimensional energetic metal-organic framework (3D EMOF) structure and an outstanding overall performance by combining high experimental density (2.10 g cm), good thermal stability ( = 220 °C), and good calculated performance of detonation ( = 8300 m s, = 29.9 GPa). Compound has acceptable thermal stability (155 °C), moderate experimental density (1.73 g cm), and good calculated performance of detonation ( = 8624 m s, = 30.8 GPa). The sensitivities of compounds and toward impact and friction were determined following standard methods (BAM). The energetic character of compounds and was determined using red-hot needle and heated plate tests. The results highlight a 3D EMOF () based on a six-membered heterocycle as a potential energetic material.

Aqueous zinc-based batteries have garnered the attention of the electrochemical energy storage community, but they suffer from electrolytes freezing and sluggish kinetics in cold environments. In this Review, we discuss the key parameters necessary for designing anti-freezing aqueous zinc electrolytes. We start with the fundamentals related to different zinc salts and their dissolution and solvation behaviours, by highlighting the effects of anions and additives on salt solubility, ion diffusion and freezing points.

Supercapacitor/pseudocapacitor structures with electrodes and electrolytes based on conductive polymers, but not only, have been analyzed using techniques. Results indicated in the literature were used to confirm the results obtained for the specific capacitance and energetic performances of the systems. New material classes like Polymer-MXene electrodes ((PANI)/TiC, PFDs/TiCT) present increased capacitance in comparison with simple polymeric composites (PETC or PTh).

In this study, the electrochemical coupling of nitrosoarenes with ammonium dinitramide is discovered, leading to the facile construction of the nitro--azoxy group, which represents an important motif in the design of energetic materials. Compared to known approaches to nitro--azoxy compounds involving two chemical steps (formation of azoxy group containing a leaving group and its nitration) and demanding expensive, corrosive, and hygroscopic nitronium salts, the presented electrochemical method consists of a single step and is based solely on nitrosoarenes and ammonium dinitramide. The dinitramide salt plays the roles of both the electrolyte and reactant for the coupling.
