Status and prospects for symmetric organic redox flow batteries

引用

Journal of Energy chemistry 2025年第1期100卷 125-143页

作者： Md Al Raihan c.Adam Dyker Department of chemistry University of New Brunswick

As environmental concerns from fossil fuel consumption intensify, large-scale energy storage becomes imperative for the integration of renewable sources like wind, hydro, and solar with the electrical *** flow batteries, particularly those employing organic molecules, are positioned as a key technology for this purpose. This review explores the growing field of symmetric organic redox flow batteries(ORFBs) within this context. Unlike traditional asymmetric designs based on unique active materials for each electrode, symmetric ORFBs involve a single bipolar species for both electrodes. This review highlights the benefits of a symmetric design, and categorizes five distinct classes of organic bipolar molecules used in both aqueous and non-aqueous solvents. By providing a comprehensive overview of their cell cycling and performance characteristics, the strengths and weaknesses of the diverse categories of bipolar molecules are highlighted for both solvent systems, as are opportunities for future development. This should guide new research directions and advance the development of practical symmetric ORFBs.

A Quantitative Analysis of Mn Segregation at Partitioned Ferrite/Austenite Interface in a Fe-c-Mn-Si Alloy

引用

Journal of Materials Science & Technology 2009年第3期25卷 383-388页

作者： H. Guo S.W. Yang c.J.Shang x.M. Wang x.L. He Department of Materials Physics and chemistry University of Science and Technology Beijing Beijing 100083 China

Mn segregation at austenite/ferrite interface is studied in a Fe-c-Mn-Si alloy held at 656℃. Mn is partitioned during the growth of ferrite and as a result, a Mn pile-up exists in front of interface on the matrix side. An approach to evaluate Mn segregation quantitatively is developed by combining STEM raster window scanning and simulation of the interaction of the electron beam with the sample to subtract the contribution of Mn pile-up and obtain pure Mn segregation value. The evaluated maximum Mn interfacial segregation is in the order of a half-monolayer.

Effect of multi-walled carbon nanotube addition on the microstructures and mechanical properties of Ti(c,N)-based cermets

引用

Journal of Advanced ceramics 2018年第1期7卷 58-63页

作者： P.WU S.c.LIU x.R.JIANG college of chemistry and Materials Science Longyan University

The surface modification of multi-walled carbon nanotubes(MWcNTs) was carried out using plasma treatment. The microstructures of the prepared cermets with different additions of MWcNTs were investigated by scanning electron microscopy(SEM), transmission electron microscopy(TEM), energy dispersive x-ray analysis(EDx), and x-ray diffraction(xRD). Mechanical properties such as transverse rupture strength(TRS), fracture toughness(K_(Ic)), and hardness(HRA) were measured. The results showed that some reactive groups were successfully modified on the surface of MWcNTs, resulting in the improvement of dispersibility. Most of the amorphous carbons and impurities were peeled from the MWcNTs. Increasing MWcNT addition decreased the dissolution of tungsten, titanium, and molybdenum in the binder phase. The cermet with 0.5 wt% MWcNT addition showed the highest TRS and fracture toughness. The strengthening mechanisms were attributed to the finer grain size, the homogeneous microstructure, and the higher volume fraction of binder phase in the binder. The toughening mechanisms were characterized by bridging and pulling-out.

concentrations of c-reactive protein (cRP) in the serum of 14 patients suffering from Lyme diseasc were measured. 86% of these patients were found to have abnormally high concentrations of serum cRP (range 14-158 mg/L). The cRP concentration of a 60-yearold patient abated from 29 mg/L to 13 mg/L after treatrnent. Results suggest that serum cRP concentration can provide a valuable and accurate means for the clinical diagnosis and monitoring of Lyme disease

critical transitions in the shape morphing of kirigami metallic glass

Journal of Materials Science & Technology 2021年第2期61卷 204-212页

Kirigami, the ancient Japanese paper cutting technique, has been applied to achieve high stretchability and low energy loss of designed metallic glass. Despite the exploration of the underlying deformation mechanism of kirigami-inspired structures from the energy point of view, the morphable responses of the kirigami patterns and the origin of the kirigami response are yet to be fully understood. This study reveals the mechanical driven-forms of the kirigami structure with the corresponding deformation stages. Based on the beam deflection theory, the elastic buckling behavior of kirigami metallic glass is manifested and a critical force prediction model is developed. Moreover, a force concentration parameter is introduced in the rigid-plastic deformation stage, predicting the nominal ultimate force. The kirigami-inspired facture force is firstly proposed. The findings of these models are in good agreement with the experimental sizedependent kirigami responses, and expected to provide significant insights into the understanding of the deformation behavior and the design of kirigami metallic glasses.
