Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT Ultrathin, lightweight, and mechanically compliant electromagnetic interference (EMI) shields are increasingly required for high‐frequency electronic devices. However, conventional metallic shields predominantly rely on conductivity‐driven reflection mechanisms, which become ineffective at reduced thickness and may cause severe secondary ...

Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT Solar‐blind ultraviolet (UV) photodetectors (SBPDs) play a critical role in applications including UV communication and fire warning systems. Gallium oxide (Ga2O3) has emerged as a promising material due to its wide bandgap and low cost, but suffers from high dark current and slow response speed caused by oxygen vacancy (VO) defects.

Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT Gradient structures (GS) introduced by plastic deformation have been shown to effectively enhance the surface properties of metallic materials. However, the GS fabricated by existing methods often suffers from limited hardening depth and limited control over the GS layer, which constrain their engineering applications.

Microstructure Tailoring of Laser Powder Bed Fused Nb521 Alloy Toward Strength‐Ductility Synergy
Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT Niobium‐based refractory alloys are promising candidates for high‐temperature aerospace structures, yet their limited ambient‐temperature ductility and poor processability remain major barriers to broader implementation. Here, Nb521 alloy was fabricated by laser powder bed fusion (LPBF), and the effects of processing conditions and subsequent ...

Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT The low energy density of sodium‐ion batteries (SIBs) remains a major barrier to their large‐scale deployment. Alloy‐based anodes represent a promising class of materials owing to their high specific capacity and low operating potential for sodium storage. However, their practical application is hindered by severe volume expansion upon cycling.

Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT Many metallic components are frequently subjected to coupled environments of friction and vibration, stemming from interfacial contact and relative motion between mating parts or external stimuli. Consequently, it is imperative for these components to exhibit a synergy of high wear resistance and superior damping properties.
