Amidst burgeoning energy demands, the integration of renewable energy sources, and the imperative of sustainability, the necessity for advanced energy storage technologies intensifies. Supercapacitors, strategically positioned between conventional capacitors and batteries, offer an alluring proposition owing to their swift charge–discharge capabilities and prolonged cycle longevity. This review delves into the fundamental role played by electrode materials in shaping the performance metrics of supercapacitors, with a focal point on Metal-Organic Framework (MOF) materials as prospective contenders. MOFs stand distinguished by their unparalleled surface area and adaptable characteristics, thus emerging as noteworthy alternatives to traditional activated carbons. Comparative analyses scrutinizing the electrochemical efficacy and sustainability facets of MOFs underscore their considerable potential within supercapacitor realms. The fusion of these materials holds promise in tackling energy storage challenges in a sustainable and efficacious manner. Ongoing scholarly endeavors are dedicated to refining their performance parameters, augmenting scalability, and expanding their application spectrum. This review engenders a comprehensive exploration of MOFs as electrodes for supercapacitors, epitomizing a transformative shift towards versatile, sustainable, and environmentally-conscious energy storage solutions. © 2025 The Korean Society of Industrial and engineering Chemistry

High entropy alloys (HEAs), which have five or more principal elements with an equiatomic composition, exhibit multiple excellent mechanical properties. Superior fatigue properties would be required to use HEAs as structural components in engineering fields. The purpose of this study is to develop HEAs having high crack propagation resistance via melamine reduction-nitridation process and powder metallurgy. The HEA compact was fabricated by mixed sintering of nitrided and un-nitrided CrMnFeCoNi powders to control the amount of nitrogen addition. Stress intensity factor, K, decreasing tests were conducted for CrMnFeCoNi alloys with nitrogen at force ratios, R, from 0.1 to 0.8 in air at room temperature. Threshold stress intensity range, ΔKth, of HEA compact with nitrogen was almost the same as the un-nitrided one at R = 0.1, whereas ΔKth of HEA compact with nitrogen was high in comparison to the un-nitrided one at R = 0.7. This was because the nitrogen addition increased the effective threshold stress intensity range, ΔKeff,th, of the HEA compact, but the magnitude of crack closure was reduced. The HEA compact with nitrogen shows excellent fatigue crack propagation properties, especially at high R conditions where crack closure does not occur. © 2024 Society of materials science Japan.

In this work, the effects of different compounding and processing techniques on the DC electrical conductivity and density of polylactic acid (PLA)/graphene nanoplatelets (GNPs) composites were studied. It is found from the study that compounding by solution mixing via an ultrasonication technique can provide slightly higher DC electrical conductivity after compression molding than mixing through a twin-screw extruder due to better dispersion quality. In addition, a composite pellet from twin screw extrusion showed a slight increase in DC electrical conductivity and anisotropy when processed by filament extrusion due to the shear alignment of GNPs during the extrusion. The fused deposition modeling (FDM) process yields high anisotropy because the crystallization along the printing path allows gaps and polymer coating between the extruded lines and layers. It was found that the 7.5 wt% GNPs composites exhibited the best properties because it provides the best dispersion quality to meet the percolation threshold. Furthermore, the micromorphology of each sample was also studied to observe the dispersion and porosity inside the composite provided by each fabrication technique. This study can be used as a reference for compounding and processing techniques. © 2023 by DEStech Publications, Inc. and American Society for Composites. All rights reserved.
