TL;DR: In this article, the effect of nitrogen concentration in carbon nanofibers (CNFs) on the structural and electrical properties of the carbon material was studied, and it was shown that the nitrogen introduction in carbon material distorts the graphite-like lattice and increases the structure defectiveness.

Review: carbon onions for electrochemical energy storage
Marco Zeiger,Marco Zeiger,Nicolas Jäckel,Nicolas Jäckel,Vadym Mochalin,Volker Presser,Volker Presser +6 more
TL;DR: Carbon onions are a relatively new member of the carbon nanomaterials family and are used as electrodes for supercapacitor applications as discussed by the authors, where they provide fast charge/discharge rates resulting in high specific power but present comparatively low specific energy.

TL;DR: In this paper, photoelectron spectroscopy has been used to study the products resulting from high temperature phase transformation of nanodiamonds (ND) and reveal the presence of oxygen-containing groups and onion-like carbon (OLC).
Journal ArticleDOI
Curvature effects in carbon nanomaterials: Exohedral versus endohedral supercapacitors
TL;DR: In this paper, the authors show that because of the positive curvature found in zero-dimensional carbon onions or one-dimensional nanotube arrays, exohedral interactions cause the normalized capacitance to increase with decreasing particle size or tube diameter, in contrast to the behavior of nanoporous carbon materials.
