From the research paper “Scalable Coating of Single-Source Nickel Hexadecanethiolate Precursor on 3D Graphitic Petals for Asymmetric Supercapacitors” authored by Ritu Gupta, Assistant Professor, Department of Chemistry, IIT Jodhpur and Timothy S. Fisher, Professor, Purdue University, which was published in the May 2017 issue of Energy Technology: Generation, Conversion, Storage, Distribution, published by Wiley Interscience, a figure illustrating the “schematic of roll-to-roll printing of nickel hexadecanethiolate ink that can be decomposed under ambient condition to yield NiOxSy as a pseudocapacitive layer” was chosen to be on the cover of the Journal.

Scalable Coating of 3D Graphene Architectures: The cover image illustrates the schematic of roll-to-roll printing of nickel hexadecanethiolate ink that can be decomposed under ambient condition to yield NiOxSy as a pseudocapacitive layer. The nickel-based pseudocapacitive layer is conformally coated onto three-dimensional graphitic structures to increase the surface area and enhance the capacitance. An optimized loading of the pseudocapacitive layer onto three-dimensional graphene petals yields a supercapacitor with high specific capacitance (2360 F g1) and stability over 5000 cycles.
