Boosting Decomposition and Combustion of TKX‐50 and HTPB/TKX‐50 Propellants With NH2‐MIL‐88B(Fe) MOF
Rare Metals, Volume 45, Issue 10, October 2026.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,

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT Non‐noble metal oxygen electrocatalysts are essential for low‐cost rechargeable metal‐air batteries and fuel cells, determining their energy conversion efficiency. However, such electrocatalysts are limited by inadequate bifunctional activity and stability toward the oxygen reduction reaction (ORR) and oxygen evolution reaction (OER).

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT Laser‐directed energy deposition (L‐DED) offers a flexible route for fabricating γ‐TiAl components, but the as‐deposited microstructure requires post‐processing to overcome limited deformation capability. Here, an L‐DED Ti–48Al–2Cr–2Nb alloy was subjected to solution and solution‐aging treatments.
