Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT NASICON‐type Na4VMn(PO4)3 (NVMP) is a promising high‐capacity cathode for sodium‐ion batteries, yet its practical deployment is hindered by Mn3+‐driven lattice distortion, persistent oxygen vacancy defects, and sluggish Na+ transport, collectively resulting in accelerated performance degradation.

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Size‐controllable Sn nanoparticles are designed in this work via oxide doping to be uniformly embedded into flexible N‐doped carbon nanofibers, in which the agglomeration and migration of Sn are effectively restrained due to the suppressive effect of selected oxides, including SiO2, TiO2, and ZnO. Benefiting from unique merits of the embedment

Shuitu Baochi Xuebao, 2007 利用相同区域湖泊沉积物及土壤培养黑藻,分析不同层次底质中各形态磷含量和间隙水中磷浓度的变化,揭示在沉水植物作用下淹水土壤和沉积物中不同层次磷的迁移规律。结果表明,本试验条件下,土壤各层次均比营养水平相当的沉积物中磷的迁移性大,黑藻能促进上层底质中无机磷向上覆水中迁移,通过根系作用促进根尖分布层底质中有机磷的迁移转化;黑藻对沉积物下层(根尖分布层)磷迁移转化的影响小于土壤,对上层底质中磷向上覆水中迁移的影响大于土壤;黑藻通过吸收作用及改变根区环境条件,影响底质间隙水中各形态磷的浓度 ...

N-cadherin对视网膜色素上皮细胞增殖及迁移侵袭的影响
Zhongshan Daxue xuebao. Yixue kexue ban, 2019 【目的】为了明确神经钙黏蛋白（N-cadherin）在糖尿病视网膜病变上皮-间质转化中的作用，探讨N-cadherin对视网膜色素上皮细胞增殖、迁移及侵袭力的影响及作用机制。【方法】分别采用Ad-N-cadherin（Ad-N-cad）、Ad-si N-cadherin（si N-cad）及Ad-GFP、Ad-si Control（si Con）对照腺病毒处理细胞以过表达或沉默N-cadherin，采取葡萄糖（25mmol/L）处理视网膜色素上皮细胞以模拟高糖状态，使用CCK8试剂检测细胞增殖情况 ...

International Journal of Applied Linguistics, Volume 36, Issue 2, Page 1282-1292, May 2026.ABSTRACT Self‐regulated learning (SRL) as a key predictor of language learning has been widely studied, but few studies have examined it from a cross‐linguistic perspective. The present study investigated whether first language (L1) SRL strategy use transfers to second language (L2) SRL strategy use and the conditions under which this transfer occurs ...

Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT Piezocatalytic technology utilizes mechanical strain or stress‐induced piezoelectric phenomena to produce robust internal electric fields, markedly improving the separation efficiency of e−‐h+ pairs. This method has emerged as a focal point in catalysis by removing reliance on conventional light or electrical energy via its mechanical‐to ...
