The pH-universal ORR performance and reaction-mechanism scheme of the Fe 1 /d-CN catalyst, which acts as cathode for flexible quasi-solid-state alkaline/neutral rechargeable Zn–air batteries.
Cell-membrane-coated nanoparticles are widely studied due to their inherent cellular properties, such as immune escape and homologous homing. A cell membrane coating can also maintain the relative stability of during circulation in a complex blood environment through encapsulation technology.
