, 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 3, March 2026.ABSTRACT Chemically self‐charging aqueous zinc‐ion batteries (AZIBs) have emerged as promising candidates for energy storage technologies owing to their environmental autonomy and structural simplicity. Nonetheless, the self‐charging performance is significantly compromised by the limited potential difference between cathodes and oxygen, as well as the

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Platinum (Pt)‐based catalysts are crucial for the commercialization of hydrogen/metal air batteries, but they suffer from Pt scarcity, high cost, and nanoparticle dissolution/agglomeration, mainly leading to performance degradation. We address this by synthesizing a PtFe alloy catalyst (PtFe–PA–NC) via a phytic acid (PA) assisted pyrolysis ...
