Three scientists won the Nobel Prize in chemistry for their work on tiny quantum dots.
Moungi Bawendi, of MIT, Louis Brus, of Columbia University, and Alexei Ekimov, of Nanocrystals Technology Inc., were honored for their work with the tiny particles that are just a few atoms in diameter and whose electrons have constrained movement. This effects how they absorb and release visible light, allowing for very bright colors. They are used in many electronics, like LED displays.
In a highly unusual turn of events, Swedish media reported the names of the winners before the prize was announced.The Royal Swedish Academy of Sciences, which awards the physics, chemistry and economics prizes, asks for nominations a year in advance from thousands of university professors and other scholars around the world.
On Tuesday, the physics prize went to French-Swedish physicist Anne L’Huillier, French scientist Pierre Agostini and Hungarian-born Ferenc Krausz for producing the first split-second glimpse into the superfast world of spinning electrons. On Monday, Hungarian-American Katalin Karikó and American Drew Weissman won the Nobel Prize in medicine for discoveries that enabled the creation of mRNA vaccines against COVID-19.
