First principles calculations are performed to investigate the structural and electronic properties of small IrGen (n = 1–20) clusters. Cage-like configurations where iridium atom is encapsulated inside a germanium cage predicted be favored for n ≥ 12. Doping Ir enhances stability corresponding frame. Our results highlight great IrGe13 which presents high-symmetry cage-like geometry peculiar st...

Nano-boron, as a potential high-energy additive due to its high calorific value, is widely studied in propellants, explosives, and thermites. However, the unexpected agglomeration of surface oxidation hinders further application, especially casting energetic materials. The fluorine-modified nano-boron nB@F2603 nB@F2603@CL-20 preagglomerated microspheres were prepared by electrospray improve ign...
