Unlocking Clean Energy: Discover the Revolutionary ‘Breathing’ Crystal That Transforms Electronics

Scientists from Korea and Japan have made an exciting discovery: a new type of crystal that can “breathe” by absorbing and releasing oxygen. This innovative material could change how we approach clean energy technologies like fuel cells, energy-efficient windows, and smart thermal devices.

The crystal is a unique metal oxide made from strontium, iron, and cobalt. Its standout feature is its ability to release oxygen when heated and then absorb it again, all while maintaining its structure. This cycle can happen multiple times, making it practical for everyday use.

Professor Hyoungjeen Jeen, who led the study at Pusan National University in Korea, emphasizes that this crystal acts almost like it has lungs. “It can inhale and exhale oxygen on command,” he explains. This characteristic is key for technologies such as solid oxide fuel cells that generate electricity with minimal emissions. It could also enhance smart windows that regulate heat flow based on weather conditions.

Until now, most materials that could control oxygen were either too fragile or functioned only in extreme temperatures. This new crystal works effectively under milder conditions, making it stable and practical. “It’s significant because only cobalt ions are reduced, leading to a new but stable crystal structure,” notes Prof. Jeen.

Notably, the crystal’s ability to revert to its original state when oxygen is reintroduced shows the process is fully reversible. This quality could pave the way for smart materials that adapt in real time. Prof. Hiromichi Ohta from Hokkaido University highlights this potential: “From clean energy to eco-friendly building materials, the applications are vast.”

Today, there is growing interest in sustainable technologies. Surveys show that over 70% of people are more likely to support businesses focused on eco-friendly practices. Innovations like this crystal could play a crucial role in meeting society’s demand for greener solutions.
