What's Happening?
A team of scientists from Korea and Japan has discovered a new type of crystal that can 'breathe' by releasing and absorbing oxygen repeatedly at relatively low temperatures. This breakthrough could significantly impact clean energy technologies, including fuel cells, energy-saving windows, and smart thermal devices. The material, a metal oxide composed of strontium, iron, and cobalt, can release oxygen when heated in a simple gas environment and then reabsorb it without degrading. This process is repeatable, making it suitable for practical applications. The study, led by Professor Hyoungjeen Jeen from Pusan National University and Professor Hiromichi Ohta from Hokkaido University, was published in Nature Communications. The material's ability to control oxygen is crucial for technologies like solid oxide fuel cells, which generate electricity from hydrogen with minimal emissions, and thermal transistors, which direct heat like electrical switches.
