Scientist Create Material That Could Allow Us To Breathe Underwater Without Oxygen Tanks

Interesting, probably a while before we actually see it, but it is pretty cool.

Hi, my name is Mike and I am currently working on a book called, 'How to Debate Atheists.' I have completed the first three chapters and would appreciate any feedback.

     Why is this here?

This doesn't belong here. Start a new topic.

The science behind this just takes my breath away...

Interesting and similar to how Haemoglobin works. Transition metals in certain oxidation states when coordinated with certain ligands (ligands are just atoms or molecules that can form what are known as coordination bonds with metals) are good at accepting Oxygen molecules. Haemoglobin is coordinated with four Nitrogen atoms and a histidine residue, leaving a "spot" open for Oxygen.

 

I accessed the abstract and it looks like the researchers are using Cobalt atoms that are coordinated with nitrate ligands. Unlike haemoglobin, this substance appears to always have six ligands coordinating with the metal in both deoxygenated and oxygenated states.

 

My question revolves around what conditions are required for Oxygen on-loading and offloading. With haemoglobin, changes in pH, temperature and substances like 2-3-DPG dictate the on-loading and offloading of Oxygen from haemoglobin. This allows haemoglobin to work under the physiological conditions within the body. I'm not sure what conditions allow the Cobalt containing substance to on-load and offload Oxygen and what consequences would stem from trying to use it.

 

It's certainly interesting and I may look at pulling the full text paper up at work next week. Unfortunately, transition metal chemistry is not exactly my specialty.
