Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT NiTi shape memory alloys (SMAs) show excellent performance in vibration damping and corrosion resistance. However, due to low hardness and lack of self‐lubrication, they suffer severe friction and wear during service. Although various strategies including doping and heterostructure design have been proposed, the effects are unsatisfactory.

Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT VO2 is a promising thermochromic material, but it is still limited by low transparency, weak solar modulation, and poor stability. Here, we develop a coordination‐compound‐derived strategy to construct a hierarchical BiVO4/VO2@BiVO4 film with a core–shell@nanosheet structure.
