GHK‐Cu Delays Aging Through the Repair of Mitochondrial Dysfunction
Rare Metals, Volume 45, Issue 11, November 2026.ABSTRACT Althugh glycyl‐L‐histidyl‐L‐lysine copper (GHK‐Cu) shows antiaging potential, its precise molecular mechanisms remain unclear. Using Caenorhabditis elegans (C. elegans) as an in vivo aging model, we observed that GHK‐Cu extended organismal lifespan and improved stress resilience.

Enhanced Microwave Attenuation via Coupled Ni3ZnC0.7/Ni3InC0.5 Heterogeneous Interfaces
Rare Metals, Volume 45, Issue 11, November 2026.ABSTRACT The growing complexity of electromagnetic environments places increasingly stringent demands on microwave absorbers, particularly regarding broadband attenuation, impedance matching in ultrathin configurations, and structural stability. Herein, we propose a dual nonstoichiometric carbide synergistic regulation strategy, in which Ni3ZnC0.7 and ...

Rare Metals, Volume 45, Issue 11, November 2026.ABSTRACT Sb2S3 is regarded as a promising anode for sodium‐ion batteries (SIBs) because of its high theoretical capacity and moderate working potential. However, it suffers from huge volume changes, poor conductivity, and excessive side reactions, leading to severe capacity decay and a low initial Coulombic efficiency (ICE), thus limiting its practical
