Abstract Rechargeable Na‐air batteries are the subject of great interest because their high theoretical specific energy density, lower cost, and charge potential compared with Li‐air batteries. However, purity O 2 as a working environment is required to achieve high‐performance batteries, which obstructs application high‐energy‐density battery. Although aqueous can operate in ambient air, long cycle safety remain challenges for electrolyte volatile. Here, quasi‐solid‐state battery reported...
Automated manipulation of discrete droplets by digital microfluidics (DMF) combined with chemiluminescence (CL) is promising to achieve automated and sensitive biosensing bioanalysis.
