Fatigue-Free and Skin-like Supramolecular Ion-Conductive Elastomeric Interphases for Stable Lithium Metal Batteries

【Research Background】 Metallic lithium is considered an ideal anode material in battery chemistry due to its high theoretical capacity (3860 mAh g -1) and low reduction potential (3.04 V vs. SHE). However, metallic lithium anodes exhibit high chemical reactivity, spontaneously forming a brittle and uneven solid electrolyte interphase (SEI) layer upon contact with organic electrolytes. … Read more

Evaluation of the Lymphatic System Function Using Diffusion Tensor Imaging Analysis Along the Perivascular Space (DTI-ALPS): A Cross-Vendor Test-Retest Validation

Abstract The method of Diffusion Tensor Imaging Analysis along the Perivascular Space (DTI-ALPS) aims to evaluate the function of the glymphatic system (GS). However, few studies have confirmed its reliability and reproducibility. DTI data from 50 participants from the MarkVCID consortium were included in this study. Two pipelines developed using DSI Studio and FSL software … Read more
