Facile Fabrication of Polyaniline/Pbs Nanocomposite for High-Performance Supercapacitor Application

open access: yesNanomaterials, 2022
In this work, a polyaniline/lead sulfide (PANI/PbS) nanocomposite was prepared by combining the in situ oxidation polymerization method and the surface adsorption process. This nanocomposite was applied as a supercapacitor electrode.

Observation of Quantum Capacitance of individual single walled carbon nanotubes [PDF]

open access: yes, 2008
We report a measurement on quantum capacitance of individual semiconducting and small band gap SWNTs. The observed quantum capacitance is remarkably smaller than that originating from density of states and it implies a strong electron correlation in ...

Nominal and Actual Values of Inductor and Capacitor Parameters at High Frequencies

open access: yesРоссийский технологический журнал, 2019
Coil inductance and capacitor capacitance depend on overall dimensions, structure, and ambient factors. They do not vary with frequency. Reactive component impedance is determined by inductance or capacitance respectively, if active resistance is not ...
