In an exciting leap toward  greener electronics , researchers at the  University of Utah  have found a way to turn  food waste  into  quantum dots —the tiny crystals that power energy-efficient LED lights in TVs, bulbs, and screens. This breakthrough could pave the way for  non-toxic, eco-friendly LEDs , replacing traditional materials like  cadmium selenide , which can be harmful to the environment. What Are Quantum Dots? Quantum dots are  nanoscale semiconductor particles  that emit vibrant, precise colors when exposed to light or electricity. They’re used in: LED TVs & displays  (for richer colors and better efficiency) Energy-saving light bulbs Medical imaging & solar cells Traditionally, these dots are made from  toxic metals like cadmium , which pose environmental risks when disposed of. But now, scientists are turning to an unlikely alternative:  food waste . From Bread Crusts to High-Tech Lights The Utah...
