Supercapacitors (or electric double-layer capacitors) are high-power energy storage devices that store charge at the interface between porous carbon electrodes and an electrolyte solution. These devices are already employed in heavy electric vehicles and electronic devices, and can complement batteries in a more sustainable future. Their widespread application could be facilitated by the develo...

Direct current electrotherapy was demonstrated to be an effective and relatively inexpensive local treatment of murine solid subcutaneous tumours. The insufficient knowledge of the mechanisms involved hinders its more extensive use in clinical oncology. Attempts were made to establish the correlation between the effectiveness of electrotherapy and deposition of the electrode material in the tum...

In this study, the internal resistance with the increasing of electrode thickness in a typical nanoporous carbon-based supercapacitor and their corresponding electrochemical performances were designed and investigated in detail. As for the carbon-based double electrode layer electrochemical system, electrochemical experiments greatly support the fact of nonlinear dependence and indicate that th...

The oxygen electrodes from two solid oxide electrolysis stacks that performed hightemperature steam electrolysis (HTSE) and produced hydrogen for 1000 and 2000 h, respectively, were examined using X-ray fluorescence, X-ray absorption near edge structure (XANES), four-point resistivity, scanning electron microscopy, energy dispersive spectroscopy, X-ray diffraction and Raman micro-spectroscopy t...

In-Situ/Operando Characterization of 2D Materials The recent advances in-situ and operando characterization materials for electrochemical energy storage devices are reviewed in the article number 2000076 by Qiang Fu, Klaus Müllen, Zhong-Shuai Wu, co-workers to comprehensively understand charge degradation mechanisms. Preparation impact preparation methods on resulting electrode structure perfor...

Zinc-based batteries are a very promising class of next-generation electrochemical energy storage systems, with high safety, eco-friendliness, abundant resources, and the absence rigorous manufacturing conditions. However, practical applications zinc-based rechargeable impeded by low Coulombic efficiency, inferior cyclability, poor rate capability, due to instability zinc anode. Herein, effecti...

this study presents a comparison between aluminum and iron plate electrodes on phosphate removal from aqueous solutions by electrocoagulation process. the effectiveness of main operational parameters such as initial ph, initial phosphate concentration and current density were examined. in addition, treated solution and sludge characteristics, energy consumption and electrode mass depletion w...

a pvc ion-selective membrane electrode based on cd-tetraphenyl porphyrine as a carrier was prepared fordetermination of mno4- ion. this electrode revealed good selectivity toward permanganate ion over a widevariety of anions. effects of some experimental parameters such as nature of the plasticizer, the amounts ofcarrier and additive, and concentration of the internal solution on the potential ...
