Azopolymer material allows light-assisted imprinting of nanostructures for structurally colored surfaces

Structural colors appear because the imprinted pattern on a surface changes the wavelengths of light. Chinese scientists have introduced an azopolymer that allows the imprinting of nanopatterns in a novel room-temperature ...

New materials undergo solid-liquid phase transitions at room temperature

Researchers have developed the first materials that can permanently change from solid to liquid, or vice versa, when exposed to light at room temperature, and remain in the new phase even after the light is removed. The researchers ...

Iridescent photonic cellulose, mimicking the structural color of insects, with optical applications

The bright colors of some butterflies, beetles or birds are not due to the presence of pigments that selectively absorb light, but due to the so-called structural coloration. Structural coloration occurs on surfaces with ...
