Bye Bye Oxygen Tanks: Aquaman Crystal To Help Humans Breathe Underwater

Bye Bye Oxygen Tanks: Aquaman Crystal To Help Humans Breathe Underwater

This is a great piece of news for scuba divers, swimmers, as well as non-swimmers – basically anyone who wants to go underwater, stay submerged and breathe as a fish. Scientists from the University of Southern Denmark and the University of Sydney, recently developed an oxygen absorbing crystal, Aquaman Crystal, or “[{(bpbp)Co2II(NO3)}2(NH2bdc)](NO3)2 * 2H2O” capable of pulling oxygen out of both air and water. The crystalline material can bind and store oxygen in high concentrations. The stored oxygen can be released again when and where it is needed.

The study, by Professor Christine McKenzie and Jonas Sundberg, showed that approximately 10 liters of microscopic crystal grains, could be enough to completely suck the oxygen out of a room.

“This could be valuable for lung patients who today must carry heavy oxygen tanks with them. But also divers may one day be able to leave the oxygen tanks at home and instead get oxygen from this material as it “filters” and concentrates oxygen from surrounding air or water. A few grains contain enough oxygen for one breath, and as the material can absorb oxygen from the water around the diver and supply the diver with it, the diver will not need to bring more than these few grains,” McKenzie said.


When the crystalline-made material, obtained by using x-ray diffraction, is saturated with oxygen, it behaves like an oxygen tank containing three times more oxygen than regular tanks.


“An important aspect of this new material is that it does not react irreversibly with oxygen – even though it absorbs oxygen in a so-called selective chemisorptive process. The material is both a sensor, and a container for oxygen – we can use it to bind, store and transport oxygen – like a solid artificial haemoglobin. It is also interesting that the material can absorb and release oxygen many times without losing the ability. It is like dipping a sponge in water, squeezing the water out of it and repeating the process over and over again,” she added.

The new material uses the element cobalt, bound in an organic molecule. “Cobalt gives the new material precisely the molecular and electronic structure that enables it to absorb oxygen from its surroundings. Small amounts of metals are essential for the absorption of oxygen, so actually it is not entirely surprising to see this effect in our new material,” she explained.

The material has been dubbed the Aquaman crystal, after the DC comic book character who can breathe underwater.


Bends comes from the phenomenon of air molecules compressing at pressure. As they compress, they enter into the muscles, etc., of the body. This is where decompression comes in — as you rise back to the surface, the air molecules begin to expand again so divers stop at stages to allow them to work their way back into the bloodstream. Otherwise, the molecules will expand in the muscles and tear them apart. The effects can range from feeling like crap to death.

Divers regularly use pure oxygen to help with decompression: it refreshes you after a long deep dive, but we’re very careful not to breathe it below 15 feet although it’s quite safe to that depth. If you breathe it down below 30 feet, it becomes quite toxic and absolutely can kill you. Regular compressed air is pretty safe to about 200 feet, although you will certainly experience nitrogen narcosis, which isn’t toxic but intoxicating — quite fun actually and there are those who seek out the experience. At 300 feet, though, the oxygen in the compressed air (about 20%), again, becomes very dangerous. Just guidelines, because people react differently. Sport divers generally are limited to 60 feet, but cave divers regularly operate at twice that depth and considerably deeper — beyond 200 feet, though, is mixed gas country.
