A research team has achieved significant breakthroughs in harnessing low-grade heat sources (|100 °C) for efficient energy conversion.

A team of researchers, jointly led by Professor Hyun-Wook Lee and Professor Dong-Hwa Seo from the School of Energy and Chemical Engineering at the Ulsan National Institute of Science and Technology , in collaboration with Professor Seok Woo Lee from Nanyang Technological University in Singapore, has achieved significant breakthroughs in harnessing low-grade heat sources within a TREC system.

"This study provides valuable insights into how structural vibration modes can enhance the energy-harvesting capabilities of TREC systems," explained Professor Hyun-Wook Lee."Our findings deepen our understanding of Prussian Blue analogs' intrinsic properties regulated by these vibration modes -- opening up new possibilities for improved energy conversion."

The potential applications for TREC systems are vast, particularly in wearable technologies and other devices where small temperature differentials exist. By effectively capturing and converting low-grade heat into usable energy, TREC systems offer a promising pathway towards the development of next-generation secondary batteries.Advanced Materials

Century's end may bring annual 100-year floodsCentury's end may bring annual 100-year floodsMost coastal communities will encounter 100-year floods annually by the end of the century, even under a moderate scenario where carbon dioxide emissions peak by 2040, a new study finds. And as early as 2050, regions worldwide could experience 100-year floods every nine to fifteen years on average.
