Summary: This review explores Mn₃O₄ nanomaterials as electrode materials for supercapacitors, emphasizing their pseudocapacitive behavior and structural advantages. Despite their high theoretical capacitance, low electrical conductivity limits their performance. Strategies such as doping with transition metals, forming composites with graphene, and intercalating alkali metal ions have been examined to enhance charge storage efficiency. The study underscores the potential of Mn₃O₄-based supercapacitors in next-generation energy storage, while highlighting the need for further research to optimize their electrochemical performance and long-term stability.

Summary: MnO₂ thin films were successfully electrodeposited onto stainless steel substrates, forming binder-free nanostructured electrodes for supercapacitor applications. Structural characterization confirmed the formation of amorphous birnessite δ-MnO₂, with XRD, FTIR, and XPS analyses validating its composition and bonding states. The electrochemical performance, evaluated through CV and GCD, revealed a high specific capacitance of 439 F g⁻¹, along with excellent energy and power densities. The study underscores the advantages of electrodeposited MnO₂, including its uniform morphology, efficient charge storage, and environmental sustainability. Future research should focus on optimizing deposition conditions, incorporating MnO₂ composites, and assessing long-term cycling stability to further enhance its supercapacitor performance.

Summary: Nickel-doped ZnO thin films were synthesized via chemical bath deposition and analyzed for their structural, optical, and magnetic properties. XRD confirmed a wurtzite structure with no secondary phases, while SEM revealed morphological evolution with Ni doping. UV-Vis spectroscopy showed band gap narrowing, and VSM confirmed room-temperature ferromagnetism due to Ni-ion interactions with ZnO defects. The optimized 2% Ni-doped ZnO exhibited superior properties, making it a strong candidate for applications in optoelectronics and spintronics.
