TL;DR: An "in-plane" fabrication approach for ultrathin supercapacitors based on electrodes comprised of pristine graphene and multilayer reduced graphene oxide to provide a prototype for a broad range of thin-film based energy storage devices.
Journal ArticleDOI

TL;DR: This work has demonstrated an efficient edge-reconstruction process, at the atomic scale, for graphitic nanoribbons by Joule heating, which involves point defect annealing and edge reconstruction.
Journal ArticleDOI
Density-functional approaches to noncovalent interactions: A comparison of dispersion corrections (DFT-D), exchange-hole dipole moment (XDM) theory, and specialized functionals
TL;DR: It is concluded that distinct, often contrasting, groups of these elicit the best performance within the accessible double-ζ or robust triple-η basis set regimes and among hydrogen-bonded or dispersion-dominated complexes.
Journal ArticleDOI
Theoretical Model for Nanoporous Carbon Supercapacitors
TL;DR: This work proposes a heuristic model to replace the commonly used model for an electric double-layer capacitor (EDLC) on the basis of anElectric double-cylinder capacitor for mesopores (2 {50 nm pore size), which becomes an electric wire-in-cylinders capacitor (EWCC) for micropores (< 2 nm port size).
