Summary: Aqueous supercapacitors with enhanced energy densities are in high demand due to their non-toxic and environmentally friendly nature. Metal oxide based pseudocapacitors can enhance the specific capacitance and energy density of the device by enlarging the potential window of the aqueous electrolyte and participating in faradaic reactions. In this study, MnO2 nanosheets were synthesized using an ecofriendly electrodeposition technique, and were found to be the best positive electrode for asymmetric supercapacitors (ASCs) due to their high charge storage capability. The effect of potassium iodide (KI) redox additive in the electrolyte on the energy density and device performance was also investigated. ASCs designed with YP-50 carbon and MnO2 as negative and positive electrodes, and optimized KI concentration, exhibited superior specific capacitance, capacity retention, and high energy density. The research provides a deeper understanding of MnO2's charge storage properties and the role of redox mediators in enhancing overall device performance in aqueous ASCs.

Summary: This paper proposes a reverse converter design for specific moduli sets using a new form of Chinese Remainder Theorem, which allows for wide modular computation. The appropriate selection of moduli is crucial for improving the speed and reducing the complexity of the converter. The modified converter relies on arithmetic designs without the need for read-only memories and lookup tables. The use of Carry Save Adder and Carry Propagate Adder in the reverse converter and modulo adder results in higher speed and less hardware complexity. The proposed converter has been implemented and evaluated for 12-bit to 100-bit conversion.

Summary: In this research, active carbon material (ACM) with a specific surface area (BET) of 1133 m(2) g(-1) was prepared from mango kernel waste through carbonization at 900 degrees C and activation with potassium hydroxide. Scanning Electron Microscopy was used to study the porous morphology of the synthesized ACM. Two supercapacitor cells were fabricated using the ACM as the electrode material and KOH 6 M & NaOH 1 M as the electrolytes. Electrochemical tests including CV, EIS, and CD techniques confirmed the suitability of the ACM as an electrode material for supercapacitors. The KOH 6 M based cell showed better performance than the NaOH 1 M based cell in terms of time constant, diffusion process, capacitive assets, energy and power density, voltage drop, and ohmic resistance. The KOH based system also exhibited good capacitance retention of 85% after 2000 life cycle tests.
