Bionic Capsule Lithium-Ion Battery Anodes for Efficiently Inhibiting Volume Expansion

Zhenhai Gao, Shun Rao, Junjun Wang, Deping Wang, Tianyao Zhang, Xinbo Feng, Yuanhang Liu, Jiawei Shi, Yao Xue, Weifeng Li, Lili Wang, Changru Rong, Yupeng Chen

Magnetite (Fe3O4) has a large theoretical reversible capacity and rich Earth abundance, making it a promising anode material for LIBs. However, it suffers from drastic volume changes during the lithiation process, which lead to poor cycle stability and low-rate performance. Taking inspiration from how plant cells mitigate excessive water uptake/loss through their cell walls to preserve the structural integrity of cells, in this work Fe3O4@PMMA multicore capsules were designed as a kind of anode material inhibiting volume expansion to promote industrial applications.

Quantitatively Tracking the Speciation and Dynamics of Selenium Nanoparticles in Rice Plants

Xiao-Xia Zhou, Quanzhi Xiao, Kena Zhang, Yan Gao, Jie Zhang, Liping Fang, Bing Yan, Fangbai Li

The uptake, translocation, and transformation of engineered nanoparticles (ENPs) in plants present significant challenges due to the lack of effective determination methods. This is especially true for selenium nanoparticles (SeNPs), which hold promise for Se-biofortified agriculture and exhibit dynamic behaviors within plant system. Herein, we proposed a novel approach that incorporates enzymic digestion and membrane filtration to selectively extract SeNPs and dissolved Se from plant tissues, employing rice (Oryza sativa) plant as a model. Subsequently, the SeNPs retained on the membrane were quantified using inductively coupled plasma mass spectrometry (ICPMS), while the dissolved Se in the filtrate, including selenite (Se(IV)), selenate (Se(VI)), and seleno amino acid, were analyzed by liquid chromatography coupled with ICPMS (LC-ICPMS). Recoveries of 83.5–91.4% for SeNPs and 73.6–99.4% for dissolved Se at a spiking level of 8 μg/g in quality control samples were obtained. With the established method, it was discovered that SeNPs taken up by rice leaves can transform into Se (IV) and organic Se, and all the Se species could be translocated downward, but only Se (IV) and SeNPs could be excreted through the roots. These findings provide valuable insights into the fate of SeNPs in plants and their related biological responses.
