The favorite color of most people, however hardly common among animals and plants. It is very difficult to produce artificially. Consequently, scientists are eagerly working on creating new blue pigments.
Part 1: In the Search of Blue
Can we really be sure where the color blue has its origin? Throughout history, it was a tedious and laborious process – or a stroke of luck.
His most famous discovery came like out of a blue sky. Mas Subramanian, a solid-state chemist at the chemical company Dupont, published hundreds of papers and dozens of patents. He had already discovered a new superconductor and a more environmentally friendly way to produce the chemical fluorobenzene. After joining Oregon State University in 2006, he worked on so-called multiferroics, a material with special electric and magnetic properties, which could lead to faster computers. Based on his idea, the PhD student, Andrew Smith, mixed indium oxide, manganese oxide and yttrium oxide and heated the mixture in an oven. The desired effect did not show, but its color was very blue.
