通过结合植物生理学、分子生物学实验以及转录组学分析，我们揭示了MgFe-LDHs促进种子出苗、增强抗低温能力和营养吸收的潜在分子机制。具体而言，MgFe-LDHs能够显著提高水杨酸（SA）的含量，从而增强CsFAD3基因的表达；同时，它还能增加赤霉素（GA3）的含量，促进氮代谢和蛋白质合成，进而提升N元素的吸收效率。此外，MgF...
近日,中国农业科学院蔬菜花卉研究所无土栽培课题组在MgFe-LDHs纳米材料的植物学应用方面取得重要进展,首次将MgFe-LDHs应用于植物营养学,发现其可以促进黄瓜幼苗生长并改善铁吸收,为进一步开发基于LDHs的复合金属纳米肥打下基础,相关研究成果...
型层状双氢氧化物(简称Mg-Fe-LDHs)纳米颗粒,考察了粒子形貌、化学组成、晶体结构、阴离子交换容量及原料配比的影响.结果表明,所合成样品为片状纳米颗粒,化学组成与原料配比基本一致.在所研究的原料配比范围内,产品中n(Mg):n(Fe)在2:1～4:1范围内,产品具有水滑石层状六方晶系结构.随n(Mg):n(Fe)从2:1...

结果表明,花瓣状Mg/Al-LDHs成功负载到生物炭表面上。Mg/Al-LDHs@BC对磷酸盐的吸附动力学过程更符合准二级动力学模型,等温吸附过程更适合Langmuir模型来描述,拟合得到的最大吸附量达71.37 mg/g,高于Mg/Al-LDHs,同时较生物炭提升约9倍。Mg/...
Notably, the application of 10 mg/L MgFe-LDHs to roots significantly increased the seedling emergence rate and growth under low-temperature stress. The application of 10 mg/L MgFe-LDHs during sowing increased the root length, lateral root number, root fresh weight, aboveground fresh weight, ...
The extensively used fluoroquinolones antibiotics are frequently detected in various water bodies, posing a severe threat to aquatic ecosystems and human health. In view of this, tumor-like Mg-Fe layered double hydroxides (Mg-Fe) LDHs nanoparticles were in situ decorated onto 3D reduced graphene ...
The studies of formation mechanism of cubic MgFe-LDHs demonstrate the type of ferric salt and reaction time are two most important parameters influencing their cubic structures. Besides, calcinations temperature can not only decide magnetic performance of MgFe2O4, but also not change its cubic ...
In addition, economic analysis indicated that the reagent cost of synthesis of zeolites/MgFe-LDHs was economical. Herein, the zeolites/MgFe-LDHs solved the natural zeolites problem for poor P removal and the application of powdered LDHs in the solid/liquid separation process, suggesting that it ...
