Smartphones, laptops, electric cars -- whatever the device, an efficient battery is high on any user's wish list. The search for the next-generation battery has recently focused on sodium- oxygen ...

Sodium-oxygen batteries are considered by many to be a particularly promising metal-oxygen battery combination. Although less energy dense than lithium-oxygen cells, they can be recharged with more ...

Medical implants such as pacemakers and gastric stimulators have improved our lives, but the batteries in these devices eventually run out and require surgery to replace them. It raises a futuristic ...

IN the isolated frog skin, it was found by Zerahn 1 and by Leaf and Renshaw 2 that the amount of sodium actively transported had a fixed relationship to the net oxygen consumption (sodium/net oxygen ...

The team explained that high-sodium-content cathodes, with insufficient interlayer spacing, are more prone to oxygen trapping ...

When the alkali metals are cut, they initially appear shiny grey but quickly become dull and white as they react with oxygen in the air. This is known as tarnishing. Sodium tarnishes more quickly than ...
