Rare Metals, Volume 45, Issue 11, November 2026.ABSTRACT The exceptional ductility of face‐centered cubic high/medium‐entropy alloys (H/MEAs) is counterbalanced by intrinsically restrained yield strength, fundamentally compromising their application in structural and functional materials. Here, a novel carbon (C)‐driven precipitation strategy is introduced to promote discontinuous precipitation (DP)

Rare Metals, Volume 45, Issue 11, November 2026.ABSTRACT Biodegradable magnesium alloys are limited in orthopedic applications due to their rapid corrosion and poor interfacial stability. In this work, a composite coating is constructed via magnetic filtered cathodic vacuum arc (MFCVA) deposition of a Zn interlayer, followed by hydrothermal in situ generation of ZnO to induce hydroxyapatite (HA ...

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.

Rare Metals, Volume 45, Issue 11, November 2026.ABSTRACT This study systematically investigates the creep behavior of an Al19Co21Fe20Ni40 eutectic high‐entropy alloy (EHEA) at 500°C, focusing on the synergistic effects of heterostructure design and trace boron doping. Thermomechanical processing was employed to produce a heterostructure consisting of alternating lamellar and equiaxed regions.

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

四川大学学报. 自然科学版, 2010 从小叶女贞叶片中提取分离了具有抑制脲酶作用的活性成分并对其抑制作用进行研究.结果显示该活性物质主要成分为多糖和酚类物质,对脲酶有较强的抑制作用,随着脲酶抑制物质浓度增加,抑制作用增强.加入β-巯基乙醇(2-Me)后,脲酶的活性恢复,说明该脲酶抑制物质是通过与脲酶的-SH发生作用而导致脲酶的活性降低.
