, 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 ...

Novos Estudos - CEBRAP, 2021 O objetivo deste artigo é argumentar que situações de privação material são inerentemente coercitivas. Para isso, avaliam-se teorias da justiça para as quais a pobreza não representaria uma forma de intervenção coercitiva em contextos de livre-mercado. Argumenta-se aqui que a pobreza precisa ser concebida como uma posição social subordinada e, portanto,

Zhongshan Daxue xuebao. Yixue kexue ban, 2019 【目的】探究锌离子在动脉粥样硬化巨噬细胞泡沫化及斑块形成过程中的影响及其机制。【方法】用氧化低密度脂蛋白（oxLDL）刺激THP-1细胞建立巨噬细胞泡沫化模型，用油红O染色法检测在0、30和60μmol/L锌浓度环境下泡沫化程度，用荧光标记法检测巨噬细胞对脂质的吞噬情况，用免疫印迹法检测相关清道夫蛋白CD36、SR-A蛋白的表达，用实时荧光定量PCR检测锌离子转运体的mRNA相对表达量。用ApoE-/-小鼠随机分4组：正常饲料组（Chowgroup）、高脂缺锌组（HFD-ZnD）、高脂正常锌组（HFD）、

Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT Low‐temperature lithium‐metal batteries (LT‐LMBs) are increasingly pursued for higher energy density and extended cycle life, yet suffer from severely depressed interfacial Li+ desolvation/diffusion kinetics due to the enlarged solvation structures as well as organic electrolyte solidification, ultimately inducing much higher barriers to ...

Shuitu Baochi Xuebao, 2018 通过水稻威优46盆栽种植试验，研究了外源Zn施用（0，40，80，160 mg/kg 4个水平）对Cd中度（0.72 mg/kg）和重度（5.26 mg/kg）污染土壤中Cd生物有效性及水稻Cd累积的差异。结果表明：施Zn对各检测指标存在影响，但土壤Cd总量仍是土壤Cd活性和水稻Cd累积差异变动的主控因素。在Cd中度污染土壤中，施Zn降低了土壤交换态Cd含量1.9%~17.0%，但水稻根表铁膜、根和糙米中Cd含量随Zn施用浓度的增大而增大，糙米Cd含量从0.09 mg/kg上升到0.17 mg/kg ...

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Aqueous zinc‐ion batteries are plagued by anode challenges such as dendrite growth and corrosion, which stem from intrinsic surface heterogeneity. Although constructing a homogeneous interfacial layer is a promising strategy, conventional electrolyte additives often suffer from incomplete or unstable coverage.
