Improving the efficiency of the electrode materials is critical for achieving high performance in supercapacitors. Porous carbon with appropriate designs is dependable for better electrochemical capacitors. In this work, we improved Zea mays (maize) cobs as a potentially plentiful precursor for generating porous carbon supercapacitor applications. The physical and chemical properties of the synthesized materials were determined using several approaches, including structure, morphology, chemical composition, and electrochemical performance. The chemical analyses revealed an oxygen-based surface structure, while structural analysis revealed a BET-specific surface area of 1443.94 m3/g and a pore volume of 0.7915 cm3/g. Symmetric devices based on the materials generated had a specific capacitance of 358.7F/g, an energy density of 12.45 Wh/kg and a power density of 250 W/kg at 0.5A/g. The as-prepared electrodes demonstrated exceptional stability, with a capacitance retention of 99% at the maximum potential for a total of 130 hours of testing.
The purpose of the study is to find the effect of master production scheduling (MPS) requirements on blood transfusion sustainability (BTS). Data was collected from 213 respondents of regional and transfusing staff of government university teaching hospital blood banks using a self-administered questionnaire. Simple random sampling was used to draw the sample. Finally, a model including MPS requirements and BTS was validated with a path analysis. The results of this study showed a positive significant effect of MPS requirements on BTS with the prediction rate of 27.1% and in the 95% confidence level.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
