Chameleons are famous for their color-changing abilities. Depending on their body temperature or mood, their nervous system directs skin tissue that contains nanocrystals to expand or contract, ...

Piezofluorochromism, the phenomenon of materials reversibly changing their fluorescent color when pressure is applied, is ...

(Nanowerk News) Chameleons are famous for their color-changing abilities. Depending on their body temperature or mood, their nervous system directs skin tissue that contains nanocrystals to expand or ...

Imagine a crystal that changes color just by coming into contact with a pollutant, almost instantly revealing its presence. Scientists at Japan’s Shibaura Institute of Technology (SIT) have developed ...

(Nanowerk Spotlight) Structural colors – the vibrant hues that arise not from pigments but from the interaction of light with microscopic structures – are among nature’s most captivating phenomena.

Charge transfer, or the movement of electrons, can occur either within a molecule or between two molecules. Combining the two types of charge transfer is challenging. Now, scientists have developed a ...

Squeezing the crystal changes how closely the molecules interact, which changes the color of light it emits from green at low pressure (left) to red at high pressure (right). In pCP-H (lower crystals) ...

Colloidal photonic crystals that can be made to change color by applying a magnetic field have been developed by researchers in the US. The crystals could be used to dramatically improve the quality ...

Imagine if there were inexpensive 3D-printed sensors that changed color to show us if something had gotten too warm or was subjected to too much stress. Well, there soon could be – and they'll ...

A donor-acceptor pyrazinacene derivative with triphenylamine substituents selectively detects naphthalene via π-hole⋅⋅⋅π interactions, inducing a striking, reversible color change from greenish-blue ...
