Hybrid Metal–Organic Framework‐Derived Dual Active Site Catalysts Enabling Surface‐Enriched Cathode and Modified Zinc Anode for Long‐Life Zinc–Air Batteries

open access: yesAdvanced Science, EarlyView.
This work demonstrates the implementation of MOF‐assisted anode and cathode materials for prolonged cycling of zinc‐air batteries with strong redox capability and structural stability. ABSTRACT The surface modification of zinc anodes and the development of effective cathode dual‐functional oxygen electrocatalysts remain of paramount interest for ...

Light Emitting Diodes

Electronics and Power, 1976
The light emitting diode (i. e. d. ) is widely used as indicator lamp, and in displays. The output covers a narrow spectral band which is defined by the material and dopants used. At present red, orange, yellow and green emitting devices are commercially available. The l. e. d. has many of the expected attributes of semiconductor devices including long
