The aptly named " Aquaman Crystal " uses cobalt to work its magic, and it doesn't need a lot — just a few grains provides enough oxygen for the first breath. As the research team notes , because the material can continually absorb oxygen from the water, a diver would only need to bring a tiny amount underwater in order to breathe without a tank.
"It is also interesting that the material can absorb and release oxygen many times without losing the ability," said Christine McKenzie, one of the scientists involved with the project. "It is like dipping a sponge in water, squeezing the water out of it and repeating the process over and over again."

It has uses beyond diving, too.
The scientists note that the material can also be used to help lung patients who breathe with the help of an oxygen tank
The atmospheric oxygen content, temperature and pressure all affect the time required for the material to absorb oxygen; it can take mere seconds or up to a few days to work. But the university emphasizes that its potential uses are myriad — cars that use fuel cells, for example, need a regulated oxygen supply.
Though there's no set timeline for the material to be converted for commercial use, the possibility is nevertheless exciting. Get ready to make like Aquaman, everyone.
