Colour changes with oxygen saturation: black when saturated, pink after oxygen release

Scientists at the University of Southern Denmark have synthesised a new material which is able to absorb oxygen from air or water, & subsequently release it in a vacuum or when heated. A few grains could supply enough oxygen for a breath. A bucketful could absorb all of the oxygen from a room.
Possible uses include SCUBA & medical oxygen without large, heavy tanks
