oxide with a layered structure for efficient insertion and extraction of sodium. The absence of cobalt in the cathode formula mitigates cost, scarcity and toxicity concerns associated with that ...

Oxide-ion conductors enable oxide ions (O²⁻) to transport in solid oxide fuel cells (SOFCs), which can run on diverse fuels beyond hydrogen, including natural gas, and biogas, and even certain ...

Oxide ion conductors used in solid-state fuel cells often fail to reach full potential when operating at temperatures below 500 degrees Celsius, but researchers have recently found a solution to ...

"This explains the extremely high mobility of the oxide ions, even at room temperature," says Ruck. "The substance remains metallic because the bismuth atoms remain bound to the iridium ions." ...

(Nanowerk Spotlight) Nanofluidic channels feature a unique unipolar ionic transport when properly designed and constructed. Recent research in nanofluidics has adopted reconstructed layered ...

Historically, the performance of the cathode in LT SOFCs has been limited by the surface oxygen exchange kinetics of the ORR as well as the mobility of oxide ion in the bulk. New cathode materials ...

Nickel is the 22 nd most abundant element on earth. The electronic structure of nickel oxide is neither completely ionic nor electron-free. Rather, it is a mixture of both structures. This structure ...
