Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT Biodegradable Zn‐based alloys are promising candidates for temporary implants, yet excessive Zn2+ release during degradation may induce cytotoxicity and adverse tissue responses. In this study, Zn‐xBa alloys (x = 0.1 wt%, 0.5 wt%, 1.0 wt% and 3.0 wt%) were developed to achieve controlled corrosion behaviors with improved biocompatibility.

Harnessing Trace Elements: Novel Radiosensitization Strategies for Enhanced Cancer Radiotherapy
Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT Radiotherapy (RT) is one of the core methods of comprehensive cancer treatment. Globally, more than 40% of cancer patients rely on radiotherapy to achieve tumor control, cure or palliative relief. However, radiation resistance, immunosuppression and normal tissue injury limit its clinical application.

, 1988 本文通过形态分级，盆栽试验及锌的专性吸附的研究。对决定石灰性土壤供给作物锌的形态进行了初步研究。 1. 选用的形态提取方法可较满意地用土壤中锌等微量元素的研究。锌形态总和与全量间的相对误差一般在10%之内，锌的大部分形态和土壤基本性质之间有较好的相关性。黄土区石灰性土壤表层各形态锌占全锌量的比例为：交换态锌(EX-Zn)0.09%、有机态锌(OM-Zn)1.20%、氧化锰结合态锌(MNOX-Zn)1.66%、碳酸盐结合态锌2.78%、无定形铁结合态锌(AFeox-Zn)

Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT Aqueous zinc‐ion batteries (AZIBs) have attracted increasing attention in energy storage owing to their high energy density, low redox potential, and cost‐effectiveness. Nevertheless, uncontrolled dendrite accumulation, gas generation, and severe side‐reaction problems hinder the cycling lifespan, which prevents their commercial applications ...
