What's Happening?
A team of researchers has developed a new man-made crystal capable of 'breathing' oxygen, which could significantly impact energy efficiency and the clean energy transition. The crystal, composed of strontium, iron, and cobalt oxides, can release and reabsorb oxygen when heated in a gas environment, mimicking the function of human lungs. This process can be repeated without degrading the material, even at moderate temperatures of around 752°F (400°C). The research, led by Professor Hyoungjeen Jeen from Pusan National University and Professor Hiromichi Ohta from Hokkaido University, was published in Nature Communications. The crystal's ability to maintain its structure while cycling oxygen makes it a promising candidate for applications in solid oxide fuel cells, which could enhance electric vehicle range and reduce emissions.
