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 stay accurate and stable. However, designing materials that combine zero expansion with good heat transfer […]
