متن کاملThermally Chargeable Supercapacitor Based on Nickel-Coated Nanoporous Carbon
Nanoporous carbon is coated by pure nickel via an electroless plating method. The nanoporous carbon provides a high-surface-area substrate, leading to a large capacitance; the nickel surface layer is of a high work function, resulting in a thermally sensitive electrode potential. Such a system is ideal for thermally chargeable supercapacitor (TCS) system, which converts low-grade heat (LGH) to ...
متن کاملOn the dynamics of charging in nanoporous carbon-based supercapacitors.
Supercapacitors are electricity storage systems with high power performances. Their short charge/discharge times are due to fast adsorption/desorption rates for the ions of the electrolyte on the electrode surface. Nanoporous carbon electrodes, which give larger capacitances than simpler geometries, might be expected to show poorer power performances because of the longer times taken by the ion...
متن کاملSynthesis and Characterization of a Novel Nanoporous Composite Based on Elemental Sulfur and Graphitic Mesoporous Carbon
A novel sulfur nanocomposite was fabricated based on graphitic mesoporous carbon.The graphitic mesoporous carbon was synthesized using sucrose as carbon precursor, nano CaCO3 as a hard template and nickel nitrate as graphitization catalyst. The structural properties of the prepared material were characterized using powder X-Ray Diffraction (XRD), N2-adsorption/de...
متن کاملthe role of task-based techniques on the acquisition of english language structures by the intermediate efl students
this study examines the effetivenss of task-based activities in helping students learn english language structures for a better communication. initially, a michigan test was administered to the two groups of 52 students majoring in english at the allameh ghotb -e- ravandi university to ensure their homogeneity. the students scores on the grammar part of this test were also regarded as their pre...
