Effects of different phosphate fertilizers on the availability and bioaccumulation of cadmium in the tea garden soil(磷肥对茶园土壤中镉有效性及其生物累积的影响)

Zhejiang Daxue xuebao. Lixue ban, 2015
通过温室盆栽试验，研究了在不同培养期内（1，2和4个月），不同磷肥（过磷酸钙、磷酸二氢钾、钙镁磷肥）及施磷量（P2O5 0.2，0.5 g • kg-1）对镉污染茶园土壤pH值、土壤有效态镉含量及茶树镉吸收累积量的影响.结果表明：钙镁磷肥的施加可有效提高茶园土壤的pH值，过磷酸钙和磷酸二氢钾对pH值的提高则不明显；过磷酸钙和钙镁磷肥均提高了 土壤有效态镉含量，且施磷量不同影响规律亦不同，而磷酸二氢钾对土壤有效态镉含量的影响不显著；茶树累积镉含量为根>茎>叶，根系对镉的富集能力极强 ...

Hierarchically Structured Zn‐ZnO@HA/PCL Biocompatible Coating: Enabling Controlled Degradation and Mechanical Stability of Magnesium Alloy Bone Implants

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 ...

Co‐Optimization of Mechanical Performance and Osseointegration of Titanium‐Based Composites via a Novel Microwave‐Driven Boronization Strategy

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.

Competitive Anion Coordination Modulates Anode Interfacial Chemistry for Wide‐Temperature Sodium Batteries

Rare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Sodium‐ion batteries (SIBs) offer a promising, cost‐effective alternative for large‐scale energy storage due to the abundance of sodium. However, their practical deployment is challenged by sluggish interfacial kinetics and unstable interphase formation, which severely limit performance across wide temperature ranges. Here, we demonstrate that

Synergistic Effect of Hydrophilic Surface and Nano‐Ag2O in TiO2‐Based Composites Coating on Antibacterial and Osteogenic Properties of Low Modulus Ti‐Mo‐Ag Alloy

Rare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT Ti‐15Mo‐2.5Ag alloy exhibited a low modulus and strong antibacterial ability but poor bioactivity. To resolve this problem, sandblasting and anodization were used to create a hydrophilic and nano‐Ag2O‐containing TiO2 coating. Subsequently, the microstructure and physicochemical properties were investigated by scanning electron microscopy, X ...

Synergetic Ruthenium Clusters and Ligand Motifs in Insoluble Polyoxometalates for Efficient Urea Electrosynthesis

Rare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT The electrocatalytic co‐reduction of CO2 and nitrate (NO3− ${\text{NO}}_{3}^{-}$) to synthesize urea presents a sustainable alternative to traditional industrial processes, yet its efficiency is fundamentally limited by the kinetically mismatched activation and coupling of CO2 and NO3− ${\text{NO}}_{3}^{-}$.
