Self‐Regulated Surface Reconstruction of Fe Modified Nickel Tellurium Oxides Enabling Highly Efficient and Durable Oxygen Evolution

Rare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Improving the efficiency and stability of oxygen evolution electrocatalysts remains essential for advancing water splitting technologies. Although in situ surface reconstruction into active phases is desirable, it often leads to uncontrolled structural degradation.

Colloid‐Mediated Surface Reconstruction Through High‐Valence Element Integration Enables Stabilized Oxygen Redox and Fast Interfacial Kinetics in Li‐Rich Cathodes

Rare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Lithium‐rich manganese‐based cathodes (LRM) deliver high discharge capacities beyond 250 mAh g−1, but their practical deployment is restricted by irreversible oxygen redox, structural reconstruction, sluggish kinetics and unstable cathode‐electrolyte interfaces (CEI). Here, we develop a colloid‐assisted anchoring‐diffusion engineering strategy

Regulating the Degradation and Cytocompatibility Behavior of Additively Manufactured Pure Zinc Through Post‐Processing Surface Treatments

Rare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Zinc‐based biodegradable metals are promising implant materials, and additive manufacturing offers a powerful route for their patient‐specific fabrication. However, process‐induced surface defects can accelerate degradation and compromise biocompatibility, rendering post‐processing essential.

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,

高能电子束辐照降解枸杞中五种农药残留

Fushe yanjiu yu fushe gongyi xuebao
为探索绿色、高效降解枸杞中农药残留的方法，提高枸杞产品质量，本研究采用高能电子束辐照的方式处理啶虫脒、吡虫啉、毒死蜱、克百威、炔螨特5种农药污染的枸杞干果样品，利用超高效液相色谱质谱联用法检测辐照前后样品中农药残留的含量，同时探究不同含水率对辐照降解农药的影响。结果表明，当吸收剂量逐渐升高时，5种农药各自的最高降解率在12.9%~41.3%范围内，其中，啶虫脒在8 kGy时，降解率最高，达到41.3%，同一吸收剂量下，枸杞干果中啶虫脒含量越低，其降解率越高。吡虫啉、毒死蜱及克百威在4 ...

From Tetracycline to Sulfamethoxazole: Photocatalytic Degradation and Mechanistic Insights in Aquatic Environments

Rare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT The pollution caused by antibiotics to aquatic ecosystems is becoming increasingly serious, thus more effective treatment methods are urgently required. Although the photocatalytic degradation behavior of tetracycline (TC) is relatively well understood, sulfamethoxazole (SMZ), an emerging pollutant originating from large‐scale livestock ...
