Summary: In this study, the electrochemical performances of hydrothermally treated α-MnO2 and δ-MnO2 were compared. The results showed that δ-MnO2 had a higher specific capacitance than α-MnO2, attributed to its layered structure and pseudocapacitance behavior. Additionally, δ-MnO2 exhibited high electrochemical stability, making it a suitable electrode material for pseudocapacitors.

Summary: In this study, MnCO3/Mn3O4 hybrid materials were synthesized using a one-step sucrose-assisted hydrothermal method. The presence of sucrose, reaction time, and temperature were found to be crucial for the final composition/structure of the obtained products. The synthesized MS-12 hybrid material exhibited better specific capacitance and cyclic stability compared to other hybrid materials.

Summary: A facile surfactant-assisted hydrothermal synthesis of layered MnO2 for supercapacitor applications was reported. The effect of different surfactants on the morphology, porosity, and electrochemical performance of MnO2 was studied. The non-ionic surfactant prevented agglomeration of nanoparticles, resulting in a more developed surface for better ion transport. Combining the MnO2 electrode with a redox-active electrolyte significantly improved the specific capacitance and electrochemical performance.

Summary: In this work, hierarchically hollow CoFe2O4/polypyrrole nanocubes with enhanced electromagnetic characteristics for MW absorption were fabricated. The electromagnetic characteristics can be adjusted by regulating the proportion of polypyrrole. The outcomes demonstrate that the as-prepared composites have outstanding MW absorbing ability and are expected to be potential MW absorbers for extensive applications.

Summary: Manganese cobaltite (MCO) nanoparticles with different morphologies were synthesized by a simple hydrothermal method and showed excellent electrochemical properties. XRD analysis confirmed the crystalline structure, while SEM and TEM revealed flake and nanoplane structures. The samples were tested using CV, GCD, EIS, and cyclic stability analysis, with the flake structures demonstrating the highest capacitance and longer stability compared to the nanoplane structures. After 5000 cycles, the electrode exhibited a high cyclic stability of 91.47%, making it a promising and durable option for energy storage devices.
