Boosting Decomposition and Combustion of TKX‐50 and HTPB/TKX‐50 Propellants With NH2‐MIL‐88B(Fe) MOF
ABSTRACT Dihydroxylammonium 5,5′‐bistetrazole‐1,1′‐diolate (TKX‐50) is a promising energetic material that possesses both exceptional energy density and low sensitivity. Nevertheless, its application is hindered by incomplete pyrolysis during combustion or explosion. Various strategies, including eutectic formation, composite preparation, and catalysis,

ABSTRACT Microstructural characterization of Li0.32La0.56Fe0.01Ti0.94Sb0.06O3 (LLFeTSO) using AC‐TEM revealed that Fe3+/Sb3+ ion co‐doping induces the migration of lattice oxygen to grain boundaries (GBs), enhancing GB conductivity. However, the atomic arrangement at the GBs remains highly ordered and lacks sufficient cation vacancy carriers.

ABSTRACT The pollution caused by antibiotics to aquatic ecosystems is becoming increasingly serious, thus more effective treatment methods are urgently required. Although the photocatalytic degradation behavior of tetracycline (TC) is relatively well understood, sulfamethoxazole (SMZ), an emerging pollutant originating from large‐scale livestock ...

ABSTRACT Biomass‐based hydrogels are widely regarded as ideal substrates for self‐powered wearable sensors. However, the practical applications of hydrogels are commonly limited by their inherent low strength and toughness, which restrict their capacity to withstand repeated stretching, bending and other mechanical loads arising from human motion in ...
