Scientists build a copper material that stays the same size at any temperature
10+ hour, 41+ min ago (435+ words) In many high-precision technologies, even tiny temperature changes can cause serious problems. Optical instruments, cryogenic systems, and sensitive sensors all rely on materials that do not expand or shrink when heated or cooled. These so-called zero-thermal-expansion (ZTE) materials help devices…...
