Abstract

original image

On page 1316 Kostya (Ken) Ostrikov and co-workers present a plasma-assisted process using butter as the natural precursor to enable the green synthesis of vertical graphene nanosheets (VGNS). The VGNS show a controllable degree of graphitization and edge planes and possess advantageous features such as large surface area, 3D and open network structure, and excellent electrical transport properties. VGNS employed as the binderfree supercapacitor electrodes exhibit high specific capacitance with excellent stability. Such performance can be further enhanced through the synergistic integration of VGNs and manganese oxide nanoparticles.
