Paper by Prof. Kakinuma and his colleagues was selected to be featured on the back cover of the journal.

　A paper by Prof. Katsuyoshi Kakinuma and Assistant Prof. Guoyu Shi of the Clean Energy Research Center and Hydrogen and Fuel Cell Nanomaterials Center, “Highly Active Nanostructured NiCoMo-Based Catalyst for Oxygen Evolution in Anion-Exchange Membrane Water Electrolysis ” was published in ACS Applied Energy Materials　by the American Chemical Society, and was selected to be featured on the supplementary cover of the journal. In this paper, the invention of a new electrocatalyst for clean hydrogen generation was reported, based on their new concepts for materials. The catalyst showed much higher oxygen evolution reaction activity, even though the noble metal was not used in the invented catalyst. Prof. Kakinuma commented that this new catalyst will contribute to the accomplishment of a Hydrogen Society soon.
