Summary: This paper proposes a new strategy, the metal organic framework/reactive antistatic agent strategy (MOF/RAA strategy), which introduces the reactive antistatic agent (WO3) into the ternary copper azide /carbon activity system. The novel reactive multi-component system (ternary copper azide /carbon/tungsten trioxide) shows high electrostatic safety and remarkable detonating ability due to the electrical conductivity and active participation of the reactive antistatic agent (WO3). This discovery provides a safe and energy-enhanced way for the design and synthesis of novel energetic compounds.

Summary: Chitosan (CTS) is an adsorbent that can absorb copper ions, and the carbon skeleton formed by the pyrolysis of CTS has excellent electrical conductivity, which improves the electrostatic safety of copper azide (CA). In this study, CTS was used to adsorb and flocculate copper ions in wastewater to form a CTS-Cu complex, which was then calcined to form a porous carbon matrix and embedded with copper nanoparticles, creating a Cu@carbonized chitosan (CCTS) precursor material. The resulting CA@CCTS is a novel lead-free primary explosive with good electrostatic safety and a high proportion of CA.

Summary: It was found that incorporating CuO into Al/I2O5 can significantly reduce the ignition time and enhance the combustion performance. The optimum composition of 80/20 wt% of I2O5/CuO shows a 30 times shorter ignition time and produces a peak pressure and pressurization rate 4 and 26 times greater than traditional Al/I2O5. A series of characterizations helped unravel the cause of improvement and propose a reaction mechanism for this ternary Al/I2O5/CuO system. This study proposes a facile, inexpensive, and efficient way to enhance the combustion performance of Al/I2O5 biocidal nanoenergetic materials.

Summary: The study investigates the quantum transport properties of anisotropic 2D group VA-VA monolayers with puckered configuration in 5 nm FETs using density functional theory and nonequilibrium Green's function. The anisotropic electronic structures of these materials provide a physical mechanism for enhancing the performance of 2D ultra-short FETs, leading to high saturation current, steep sub-threshold swing, and high on-current. This suggests that strong anisotropic electronic structure can be a target feature for designing high performance 2D FETs, guiding the exploration of excellent 2D channels for ultra-scaled electronic devices.
