Spatiotemporally Adaptive Bilayer Silk Fibroin–Polyvinyl Alcohol–Metformin Composite Coating on Biodegradable Zinc for Orthopedic Applications

open access: yesRare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT Biodegradable zinc (Zn)‐based materials are considered promising candidates for orthopedic applications because of their favorable mechanical properties, controllable biodegradability, and good biosafety profiles. However, their clinical translation is limited by early‐stage corrosion‐induced cytotoxicity and inflammation, as well as ...

Synergistic Dual‐Defect Engineering in Amorphous‐Nanocrystalline Heterostructures for Accelerated Oxygen Evolution

open access: yesRare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT Defect engineering has been widely demonstrated as an effective strategy for enhancing the activity of OER metal catalysts, among which the introduction of twin boundaries (TBs) has proven particularly efficient. However, single‐type defects offer limited performance enhancement.

Kinetic‐Controlled Growth of Iron Chalcogenide Nanosheets Featuring Besnus Transition

open access: yesRare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT Two‐dimensional (2D) Fe‐based nanosheets have sparked wide attention owing to exotic magnetism, superconductivity and topological phases. However, the synthesis of 2D FemXn (X = Te/Se/S, m, n: integer), typically in a non‐stoichiometric ratio, remains challenging because of narrow thermodynamic windows.

An Ultrasound‐Triggered Antibacterial Hydrogel With Integrated Antioxidant and Angiogenic Functions for Infected Wound Care

open access: yesRare Metals, Volume 45, Issue 5, May 2026.
ABSTRACT Managing diabetic wounds requires simultaneously addressing their infectious, oxidative, and regenerative impairments. To address this, this study integrates a piezoelectric BiOCl@CuSe heterojunction (PFM‐verified) into an injectable F127/HA hydrogel, creating an ultrasound‐responsive smart dressing.

粘土矿物对荧蒽在表层沉积物上吸附特性的影响

open access: yes四川大学学报. 自然科学版, 2012
基于长江、嘉陵江重庆主城段不同粒径表层沉积物样品,进行了粘土矿物(高岭石、蒙脱石)掺混前后对典型多环芳烃荧蒽的吸附特性研究,试验结果表明,荧蒽的吸附能力与表层沉积物粒径大小具有一定的相关性;沉积物粒径越小,其吸附能力相对越强.不同粒径的表层沉积物对荧蒽的等温吸附曲线表明,对于相同的液相平衡浓度,固相吸附量大小依次为320目>240目>120目.沉积物样品中粘土矿物的掺混可显著增强其对荧蒽的吸附能力,且蒙脱石优于高岭石,这是由于不同粘土矿物晶型构成存在差异.沉积物样品对荧蒽分配特性的分析结果表明 ...

A Dual Co‐Reactant Accelerator Based On Nanoreactor‐Encapsulated CeO2 Nanozymes to Drive Potentiated Luminol Cathodic Electrochemiluminescence for Ultrasensitive Immunoassay

open access: yesRare Metals, Volume 45, Issue 5, May 2026.
ABSTRACT The precise quantification of cytokines is crucial for monitoring disease onset and progression. Herein, we developed a synergistic signal amplification approach by utilizing nanoreactor‐encapsulated CeO2 nanozymes, which were in situ electrodeposited within the mesoporous silica nanochannel film (SNF) grown on indium tin oxide (ITO ...

连环湖敖包泡沉积物磷形态垂向分布特征

open access: yesShuitu Baochi Xuebao, 2017
应用SMT连续提取法对连环湖敖包泡北部(AB1)和南部(AB2)柱状沉积岩芯中磷形态的含量和垂向分布特征进行对比分析,结合沉积岩芯年代测定,探讨了该湖区沉积物中磷的演化特征与人为污染历史以及内源磷的释放风险。结果表明,AB1、AB2沉积物中磷形态的含量和垂向变化不同,AB1沉积物中各形态磷含量均高于AB2,且随深度变化波动较大。20世纪40年代中期至1981年,AB1沉积物各形态磷和OM含量波动较大;AB2沉积物中Ca-P、IP、TP含量呈先增加后减少之势,Fe/Al-P、OP、OM含量变化较稳定 ...
