To infinitesimal and beyond – an electron structure explanation of supercapacitance

By Eileen De Guire / June 24, 2011

Computational modeling of carbon supercapacitors with the effects of surface curvature included. Credit: Jingsong Huang, ORNL A fair number of recent posts have been about nanostructured porous materials (PCCMs, diamond aerogel, tunable gold). The interesting characteristics of these materials necessarily depend on the porosity: What is not there makes the material what it is. The…
