Bio-inspired copper composite achieves zero thermal expansion and high heat transfer Zero-thermal-expansion (ZTE) materials are widely used in precision optics, cryogenic equipment and sensors, where even small temperature changes can cause performance problems. Yet creating ZTE materials that also conduct heat efficiently and remain mechanically robust has long been a challenge. Most conventional ZTE materials…
