Zn-ion batteries (ZIBs) are considered promising alternatives to conventional Li-ion secondary due their high safety, environmental friendliness, and cost-effectiveness. Despite these advantages, uneven metal plating stripping, dendrite formation, passivation corrosion owing the hydrogen evolution reaction (HER) have hindered practical implementation of ZIBs. A route for overcoming problems involves coating Zn anode with eutectic gallium indium (EGaIn)-based liquid (LM) a strong affinity growth direction tenability. considerable research on EGaIn-coated anodes ZIBs, this topic has not been comprehensively reviewed. Hence, Review introduces application LMs ZIBs particularly discusses mitigation stability issues using LM fundamental processes related anodes. We summarize progress in field suggest future directions advance

Biological ion channels penetrated through cell membrane form unique transport pathways for selective ionic conductance. Replicating the success of selectivity with mixed matrix membranes (MMMs) will enable new separation technologies but remains challenging. Herein, we report a soft substrate-assisted solution casting method to develop MMMs penetrating subnanochannels metal conduction. The are composed Prussian white (PW) microcubes in dense polyimide (PI) matrices, achieving monovalent K+ /Mg2+ is up 14.0, and conductance can reach 45.5 μS testing diameter 5 mm, which be further improved by increasing area. Given diversity nanoporous materials polymer expect that could developed into versatile nanofluidic platform various emerging applications.

Atomic Ru-Doped Ni_0.85Se Nanosheets as Efficient Electrocatalysts toward Simulated Seawater Hydrogen Evolution

Energy & Fuels, Journal Year: 2023, Volume and Issue: 37(23), P. 18204 - 18209

Published: Aug. 31, 2023

The development of affordable and efficient catalysts for seawater hydrogen evolution is highly desirable but presents significant challenges. In this study, we prepared an exceptionally electrocatalyst, atomic Ru-doped Ni0.85Se supported on carbon cloth (Ru–Ni0.85Se/CC–12 h), the reaction (HER) in both a 1 M KOH solution alkaline-simulated environment (1 0.5 NaCl). Notably, Ru–Ni0.85Se/CC–12 h exhibited excellent performance with remarkably low overpotentials 34.1 44.2 mV at 10 mA/cm2 environment, respectively. Furthermore, it demonstrated remarkable durability, showing negligible degradation even after continuous 18 mA/cm2. outstanding HER alkaline can be attributed to Ru doping Ni0.85Se, which modifies its geometric electronic structure, thereby enhancing activity resistance chloride ion poisoning erosion simultaneously.

Abstract Integrating nanomaterials into the polymer matrix is an effective strategy to optimize performance of polymer‐based piezoelectric devices. Nevertheless, trade‐off between output enhancement and stability maintenance composites usually leads unsatisfied overall for high‐strength operation Here, by setting liquid metal (LM) nanodroplets as nanofillers in a poly(vinylidene difluoride) (PVDF) matrix, as‐formed liquid‐solid/conductive‐dielectric interfaces significantly promote reliability this composite. A giant improvement featured obtained with, nearly 1000% boosting on voltage (as high 212 V), 270% increment coefficient ( d 33 ∼51.1 pC N −1 ) long‐term both structure (over 36 000 cycles). The design novel heterogenous interface with mechanical matching electric coupling can be new orientation developing composite‐based
