Like diamonds, sugar crystals ideally are very pure and low in color. Now studies have provided a better understanding of the source of undesirable color in factory sugar. Like diamonds, sugar ...

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, ...

It has been a while since I have covered colloidal photonic crystals here on Nobel Intent. Last time, I wrote about research that showed how one could fine tune the crystal lattice with an applied ...

Scientists studying chameleon skin have discovered the secret to the lizards’ color-changing prowess: Rather than relying purely on pigments, the animals use photonic nanocrystals in their skin to ...

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 ...

(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.

A recent study has discovered a novel way to manufacture single gyroid photonic crystals to work in the visible light spectrum, based on the self-assembly mechanism found in blue-winged leafbirds. A ...

This release is available in Spanish. Like diamonds, sugar crystals ideally are very pure and low in color. Now studies led by U.S. Department of Agriculture (USDA) chemist Gillian Eggleston have ...
