HKUST discovers novel elastic alloy achieving 20x temperature change and 90% carnot efficiency in solid-state heat pumping

Researchers at HKUST developed a novel elastic alloy called Ti₇₈Nb₂₂, which achieves remarkable efficiency for solid-state heat pumping and exhibits a reversible temperature change 20 times greater than conventional metals. The alloy achieves approximately 90% of the Carnot efficiency limit, making it highly competitive with refrigeran...
