Mandi, August 16: Researchers at the Indian Institute of Technology (IIT) Mandi have developed advanced materials that could revolutionize energy efficiency and cooling technologies. The team’s successful findings promise to enhance applications in various industries including power generation, electronics and high-end computing.
The research, led by Dr. Ajay Soni from the School of Physical Sciences at IIT Mandi, focused on thermoelectric materials and superionic conductors. These materials are unique in their ability to conduct electricity efficiently while minimizing heat transfer, a combination that is highly beneficial for energy generation and cooling systems.
“Thermoelectric materials challenge the norm by being excellent electrical conductors yet poor conductors of heat,” explained Dr. Soni. “This makes them ideal for applications such as energy recovery and cooling in advanced electronics.”
Dr Soni’s team studied the large unit cell mineral chalcogenides, which are known for their complex crystal structures. The research revealed that irregular atomic vibrations within these crystals play a key role in reducing thermal conductivity. This discovery could lead to more efficient thermoelectric materials, enabling better cooling systems and more effective energy recovery technologies.
The team also discovered superionic conductors, including silver and copper, known for their excellent ionic conductivity. Despite being crystalline, these materials have thermal properties similar to glass, making them ideal for mid-temperature heat harvesting and advanced battery technologies. “By understanding how these atoms vibrate in superionic conductors, we can improve materials used in energy storage and conversion,” said Dr. Soni.
Supported by a Core Research Grant from the Science and Engineering Research Board of the Government of India, these findings mark a significant advance in materials science. IIT Mandi’s research not only enhances energy efficiency but also provides new avenues for developing sustainable solutions across various industries.
These innovative materials have the potential to advance future technologies, making energy systems more efficient and sustainable.
