Every time you get a haircut, a pile of hair ends up in the trash. Most people probably do not pay much attention to this, but a group of researchers in Australia examined that very pile of hair and found an innovative material for screens in the future. In a study conducted by scientists at Queensland University of Technology (QUT) and Griffith University and published in the journal Advanced Materials, scientists turned waste hair into tiny glowing particles known as carbon dots and built them into OLED displays, similar to the display technology currently used in many phones and televisions.
