FD Electrolysis: Calcium Manganite as oxygen electrode materials for reversible solid oxide fuel cell

22.04.2015 | Chengsheng Ni; John T.S. Irvine, Faraday Discussions, 2015

For an efficient high-temperature reversible solid oxide fuel cell (RSOFC), the oxygen electrode should be highly active for the conversion between oxygen anions and oxygen gas. CaMnO3-δ(CM) is a perovskite that can be readily reduced with the formation of Mn3+ giving rise to oxygen defective ...

[Report] Eddy-driven subduction exports particulate organic carbon from the spring bloom

10.04.2015 | Melissa M. Omand; Eric A. D’Asaro; Craig M. Lee; Mary Jane Perry; Nathan Briggs; Ivona Cetinić; Amala Mahadevan, Science , 2015

The export of particulate organic carbon (POC) from the surface ocean to depth is traditionally ascribed to sinking. Here, we show that a dynamic eddying flow field subducts surface water with high concentrations of nonsinking POC. Autonomous observations made by gliders during the North Atlantic ...
