TL;DR: Pt-modified covalent triazine frameworks selectively catalyze hydrogen oxidation, even in the presence of dissolved oxygen, which is critical for limiting cathode degradation during the start-stop cycles of fuel cells.
Abstract: Reducing the use of platinum (Pt) on polymer electrolyte fuel cell anodes is critical for the widespread dissemination of these energy conversion systems. Although Pt usage can be minimized by the even dispersion of isolated Pt atoms, no atomically dispersed Pt catalysts that promote hydrogen oxidation at a rate required for practical fuel cells have been reported to date. Covalent triazine frameworks with atomically dispersed Pt atoms (0.29 wt %) are described and it is demonstrated that the material has a high electrocatalytic hydrogen oxidation activity without an overpotential. Importantly, when the loading amount was increased to 2.8 wt %, the electrocatalytic hydrogen oxidation activity of the resulting electrode was comparable to that of commercial carbon supported 20 wt % Pt catalysts, and the catalytic activity for oxygen reduction was markedly reduced. Thus, Pt-modified covalent triazine frameworks selectively catalyze hydrogen oxidation, even in the presence of dissolved oxygen, which is critical for limiting cathode degradation during the start–stop cycles of fuel cells.

TL;DR: In this article, a color image reproduction sheet for use in an electrophoretic color image reproducing apparatus is presented, which has a suspension layer having a white colored suspending medium and at least three differently colored photosenstive electrophoric materials in the form of finely divided powder suspended in the white coloured suspending medium.
Abstract: A color image reproduction sheet for use in an electrophoretic color image reproducing apparatus. The sheet has a suspension layer having a white colored suspending medium and at least three differently colored photosenstive electrophoretic materials in the form of finely divided powder suspended in the white colored suspending medium, the three differently colored photosensitive electrophoretic material consisting essentially of cyan colored material which is principally photosensitive to red light, magenta colored material which is principally photosensitive to green light, and yellow colored material which is principally photosensitive to blue light. The suspension layer is supported on a base, so that when the sheet is passed between a substantially transparent first electrode and a second electrode which are spaced from and opposed to each other with the electrodes against the two opposite major surfaces of the suspension layer, respectively, with the transparent electrode against the free surface of the suspension layer, and a D. C. electric field is applied across the suspension layer between the electrodes, and the suspension layer is exposed to a color image through the transparent electrode, the D. C. electric field changes electrophoretically, in cooperation with the color image, the spatial distribution of the three differently colored photosensitive electrophoretic materials so that the optical reflective property of the suspension layer changes in accordance with the color image.
