A joint research group consisting of Kanazawa University, Tohoku University, Osaka University, and Tsukuba University has designed a graphene edge structure composed of a single layer of carbon atoms from a mathematical point of view, and by chemically doping nitrogen in the edge structure of graphene ( N) and phosphorus (P), purposely formed geometric deformation. On this basis, calculations have found that graphene with a chemically doped edge structure has a high hydrogen generation ability and can greatly enhance the hydrogen generation reaction. The results obtained are close to the use of high-priced precious metal platinum, thus confirming for the first time that the non-metallic elements Chemical doping and specially designed graphene edge structure help to improve the electrode's reaction performance. (Reporter Chen Chao in Japan) Intergrated Led Emergency Modules The Intergrated Led Emergency Modules is match the compact LED fittings to improve the emergency function. Normally it is workable for small wattage from 3-60W LED panels, downlights, led tubes, tri-proof ceilings. Full power output or half power emergency output is optional. Customized emergency lighting time is available. Automatic lighting up when main power failures. Widely using for home, parking lot, office, building, warehouse, school, hospital, workshop etc. Emergency Light Module,Emergency Led Flasher Module,Led Emergency Modules,Intergrated Led,led light with emergency battery Foshan Nai An Lighting Electric Co.,ltd , https://www.naipslighting.com
