A team of scientists at the University of California-Riverside announced on Monday that they have developed new particle that one day might be developed into a new sunlight friendly screen.

These particles are made from iron oxide and silicon dioxide molecules, and they are formed into microscopic strings, or “nanorods”. These nanorods, when packed into a screen, should one day be usable as an alternative to E-ink and other epaper screens.

At this point, however, the nanorods don’t hold position position without a magnetic field, so they won’t be as energy efficient as existing epaper options. In the words of Professor Yadong Yin, the team leader, “One major advantage of the new technology is that it hardly requires any energy to change the orientation of the nanorods and achieve brightness or a color. A current drawback, however, is that the interparticle spacing within the chains gets fixed once the silica coating is applied, allowing for no flexibility and only one color to be displayed.”
