Gongye shui chuli, 2005 采用静态阻垢法、SEM、XRD分析技术研究了PO43-与三元共聚物AA/AMPS/HPA对CaCO3垢的作用。结果表明:单独的PO43-对CaCO3无任何阻垢作用;8～20mg/LAA/AMPS/HPA+1～6mg/LPO43-在阻CaCO3垢时表现出显著的协同效应,当PO43-质量浓度超过6mg/L时,两者阻CaCO3的阻垢率下降,协同效应也不明显。PO43-与AA/AMPS/HPA三元共聚物使CaCO3的形貌发生变化,对方解石的形成有明显的抑制作用。

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT The use of Ti6Al4V alloy in dental implantation is constrained by its high elastic modulus and biological inertness, which lead to delayed osseointegration and a high failure risk. Additionally, its chemical incompatibility with hydroxyapatite (HA) impedes the development of stable bioactive composites.

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

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT Developing rapid, precise gas sensors for Listeria monocytogenes (LM) biomarker detection faces challenges due to suboptimal gas‐solid interactions. Herein, we report the rational synthesis of amino‐functionalized mesoporous SiO2 hollow nano‐doughnuts (MS‐2‐NH2‐2) via modification with (3‐aminopropyl) trimethoxysilane (AAPTMS), which enables ...

Ultrasonic Vibration Assisted Laser Processing: A Hybrid Paradigm for Extreme Surface Enhancement
Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT Traditional laser processing techniques offer many advantages, but they often encounter limitations such as heat‐affected zones, recast layers, residual tensile stresses, and poor surface finish. The integration of ultrasonic vibration (UV) presents a promising hybrid approach to overcome these challenges by introducing beneficial effects like
