(Nanowerk Spotlight) From dot matrix to 3D, color printing technology has come a long way in the past 40 years. All of these technologies have created colors by using dye inks, which not only limits ...

From dot-matrix to 3-D, printing technology has come a long way in 40 years. But all of these technologies have created hues by using dye inks, which can be taxing on the environment. Now a team ...

WASHINGTON D.C., September 30, 2014 – Applying a well-known optical phenomenon called thin-film interference, a group of researchers at Harvard University has demonstrated the ability to "paint" ultra ...

Interference of two combined white light beams produces Newton colors if one of the beams is retarded relative to the other by from 400 nm to 2000 nm. In this case the corresponding interfering ...
