Microemulsions, as thermodynamically stable mixtures of oil, water, and surfactant, are known have been studied for more than 70 years. However, even today there still quite a number unclear aspects, recent research work has modified extended our picture. This review gives short overview how the understanding microemulsions developed, current view on their properties structural features, in particular, they related to applications. We also discuss developments regarding nonclassical such surfactant-free (ultraflexible) or ones containing uncommon solvents amphiphiles (like antagonistic salts). These new findings challenge some extent previous microemulsions, which therefore be look at different types unified way. In flexibility amphiphilic film is key property classify microemulsion this review.

Energy Storage Mechanism in Supercapacitors with Porous Graphdiynes: Effects of Pore Topology and Electrode Metallicity

Advanced Materials, Journal Year: 2023, Volume and Issue: 35(33)

Published: April 30, 2023

Porous graphdiynes are a new class of porous 2D materials with tunable electronic structures and various pore structures. They have potential applications as well-defined nanostructured electrodes can provide platforms for understanding energy storage mechanisms underlying supercapacitors. Herein, the effect stacking structure metallicity on such is investigated. Simulations reveal that supercapacitors based AB achieve both higher double-layer capacitance ionic conductivity than AA stacking. This phenomenon ascribed to more intense image forces in stacking, leading breakdown ordering formation effective "free ions". Macroscale analysis shows doped deliver outstanding gravimetric volumetric power densities due their enhanced quantum capacitance. These findings pave way designing high-performance by regulating topology electrode materials.
