Most of the objects we see are colored by pigments, but using pigments has disadvantages: such colors can fade, industrial pigments are often toxic, and certain color effects are impossible to achieve. The natural world, ...
A multicolor laser pointer you can use to change the color of the laser with a button click—similar to a multicolor ballpoint pen—is one step closer to reality thanks to a new tiny synthetic material made at Sandia National ...
Butterflies often display strikingly different colour or patterns on the dorsal (top) and ventral (bottom) sides of their wings. A study by researchers from the National University of Singapore (NUS) has revealed that the ...
Engineers have invented tiny structures inspired by butterfly wings that open the door to new solar cell technologies and other applications requiring precise manipulation of light.
Research by the NUP/UPNA-Public University of Navarre has proposed various designs for photonic crystal materials that can be used to filter radiation. Specifically, the focus has been to develop a coating comprising dielectric ...
Butterflies' special place in human culture stems from the fact that they have used their wings not only for flight, but as a canvas for some of the most striking patterns in nature. Evolving from an ancestral moth-like insect ...
Creatures like the Morpho butterfly on the leaf above appear to be covered in shimmering blue and green metallic colors. This phenomenon is called "iridescence," meaning that color appears to change as the angle changes, ...
The unique properties found in the stunning iridescent wings of a tropical blue butterfly could hold the key to developing new highly selective gas detection sensors.
A pair of researchers, one from Oxford University, the other with the Natural History Museum in London, has found a way to grow butterfly wings in their lab. In their paper published in Bioinspired, Biomimetic and Nanobiomaterials, ...
Solutions required for progress on the frontiers of photonics technology are close at hand: in nature, when viewed through the perspective of engineer, says Montana State University optics researcher Joseph Shaw. Along with ...
