Mechanical metamaterials are man-made structures with counterintuitive mechanical
properties that originate in the geometry of their unit cell instead of the properties of each …

Red phosphor materials play a key role in improving the lighting and backlit display quality
of phosphor-converted white light-emitting diodes (pc-WLEDs). However, the development …

Negative thermal expansion (NTE), referring to the lattice contraction upon heating, has
been an attractive topic of solid-state chemistry and functional materials. The response of a …

Negative thermal expansion (NTE) is an intriguing physical property of solids, which is a
consequence of a complex interplay among the lattice, phonons, and electrons …

By virtue of the unique advantages of compensating and controlling thermal expansion,
negative thermal expansion (NTE) materials have attracted great attention and have gained …

Negative thermal expansion (NTE) is a counterintuitive physical phenomenon that the unit
cell volume of material usually contracts instead of expands upon heating. With two …

Materials with negative Poisson's ratio attract considerable attention due to their underlying
intriguing physical properties and numerous promising applications, particularly in stringent …

Most materials expand upon heating. However, although rare, some materials contract upon
heating. Such negative thermal expansion (NTE) materials have enormous industrial merit …

Negative thermal expansion (NTE) is the phenomenon in which materials shrink rather than
