Abstract: Metal-assisted delayed fluorescent (MADF) emitters including cyclic tetradentate platinum (II) and palladium (II) complexes employing 8H-pyrido[3?,2?:4,5]-pyrrolo[3,2,1-de]acridine and its analogues. These complexes provide improved color purity and enhanced operational stability and are suitable for luminescent labels, emitters for organic light emitting diodes (OLEDs), and lighting applications.

Abstract: We disclose quinone compounds and related species (Formula I) that possess significant advantages when used as a redox active material in a battery, e.g., a redox flow battery. In particular, the compounds provide redox flow batteries (RFBs) with extremely high capacity retention. For example, RFBs of the invention can be cycled for 500 times with negligible loss of capacity, and such batteries could be employed for years of service. Thus, the invention provides a high efficiency, long cycle life redox flow battery with reasonable power cost, low energy cost, and all the energy scaling advantages of a flow battery.

Abstract: The invention discloses a dry etching device and an electrode thereof. The electrode comprises an electrode base, an insulation layer arranged on the electrode base, and an edge stage located on a peripheral surface of the insulation layer. The edge stage comprises at least a pad each for receiving a lifter pin of the dry etching device. The edge stage comprises various embosses arranged peripherally on the edge stage, so that small gaps are present around the embosses between the substrate and the edge stage. Therefore, the adhesive force between the substrate and the edge stage can be reduced, the adsorption phenomenon can be efficiently improved, the yield of the etched substrate can be enhanced and the life of the electrode of the dry etching device can be increased.
