TL;DR: In this article , a review of two-dimensional material-based supercapacitors for energy storage applications is presented, where the main attention of the appraisal stands on the capacitors employing the pseudo mechanism but those based on electrochemical double layer and faradaic mechanism along with performance evaluation.
Abstract: The necessity for advancement in the field of energy storage devices is inevitable due to the forthcoming exhaustion in the availability of primitive hydrocarbon deposits. Benign and ecological renewable sources can opt as the perfect substitution for fossil fuels as a remedy for sustainability, which can be stored to meet the overflowing energy demand. Even a single spark in the development of energy storage devices can be viewed as an explosion in the execution of future energy concerns. This review is a token of recent progress in the arena of two-dimensional material-based supercapacitors for energy storage applications, manuscript starts with the need for energy storage devices in the anticipation of upcoming energy catastrophe. A brief introduction to the capacitors along with their classification under various parameters and their peaks and valleys in storing energy are included in the review. The chief attention of the appraisal stands on the capacitors employing the pseudo mechanism but those based on electrochemical double layer and faradaic mechanism are also included along with performance evaluation. The role of various 2D materials including graphene, molybdenum-based TMDs, tungsten-based TMDs, MXene, two-dimensional metal-oxides and phosphides in enhancing the charge storage performance are scrutinized in the review.

TL;DR: In this paper , the strontium aluminium hexaferrite was substituted with the divalent ions (Ba/Ca) with the chemical formula of Sr1-xMxAl2Fe10O19 (M = Ba, Ca; x = 0.1, 0.2), and all the samples were synthesized via sol-gel auto combustion method.
Abstract: The strontium aluminium hexaferrite was substituted with the divalent ions (Ba/Ca) with the chemical formula of Sr1-xMxAl2Fe10O19 (M = Ba, Ca; x = 0.1, 0.2), and all the samples were synthesized via sol-gel auto combustion method. The particles are shaped in a hexagonal structure with space group P63/mmc. The field-emission scanning microscopy revealed the platelet-like morphology of the particles. The magnetic studies disclosed the single-domain arrangement of particles and decent energy product value for all the samples (0.36–0.38 MG Oe), implying their potential application in permanent magnets. The declined value of the Dielectric constant at mega-range frequency suggests that the samples could be useful for microwave application.
TL;DR: In this paper , a liquid phase exfoliation of MoS2 powder in different solvents with varying surface tension was employed to obtain the structural and optical properties of the sample.
