Weird and colorful quantum dots earn chemistry
This year’s Nobel Prize in Chemistry is for quantum dots, the tiny particles lighting up TV screens, LEDs, medical imaging and more. Three scientists are sharing the prize: Moungi G. Bawendi, Louis E. Brus and Alexei I. Ekimov. Together, these scientists colored the future of nanoscience.
