Article Abstract
Covalent organic polymers (COPs) have garnered attention as potential materials for various applications, including catalysis, gas storage, and energy production. Owing to their highly conjugated structures, chemical stability, adjustable band gap, and tunable functionality, COPs have emerged as a versatile material. However, their inherent structural rigidity and poor conductivity pose challenges for energy storage applications. To address these limitations, graphene has been incorporated as a conductive filler due to its exceptional conductivity and structural integrity. This study presents an innovative approach utilizing electrophoretic exfoliation of a graphite strip to develop a COP-graphene nanohybrid system (RTh-COP-EGR) that enhances supercapacitor performance. Due to the synergistic effect of heteroatom-enriched RTh-COP and conductive graphene layers, the resulting RTh-COP-EGR nanohybrid exhibits a capacitance of 4.2 mF cm at a current density of 70 μA cm, with an energy density of 0.4725 mW h cm and a power density of 314.4 W cm at higher current densities. Furthermore, this nanohybrid exhibits an impressive capacity retention of 82% over 10 000 cycles, showcasing its potential for advanced energy storage applications.

A series of Cu-based single-atom catalysts (SACs) with asymmetric coordination were designed to accelerate lithium-sulfur (Li-S) chemistry. The electronegativity contrast from the dopant induces a localized electronic asymmetry that amplifies Jahn-Teller distortion at the Cu center. This distortion profoundly modulates the Cu 3d electronic structure and its interaction with Li-S intermediates.

Bismuth ferrite (BiFeO) is a semiconductor with multiferroic properties, synthesized by the sol-gel method. While static high-pressure studies have advanced our understanding of the phase behavior of BiFeO, the effects of dynamic pressure acoustic shock waves remain unexplored. In this study, BiFeO was subjected to 100 shock pulses with 0.

Isovalent anion substitution has been shown to have a tremendous effect on the transport properties in lithium halide solid ionic conductors. Although sodium-ion solid state batteries based on chloride ionic conductors have recently gathered significant attention, investigations of anion substitution in sodium containing chlorides remain scarce. Here, we investigate the role of Br isoelectronic anion substitution in a perovskite-related compound with nominal composition of NaTaCl.
