TIME.CO, Jakarta – Scientists Moungi Bawendi, Louis Brus and Alexei Ekimov won Nobel prize Chemistry in 2023 for the “discovery and synthesis of quantum dots”, which illuminate computer monitors and television screens and are used by doctors to map tumors. The winner announcement was broadcast on Wednesday afternoon, October 4, 2023 WIB.
“The Nobel Prize winners… succeeded in producing particles so small that their properties are determined by quantum phenomena. These particles, called quantum dots, are now of great importance in nanotechnology,” the Nobel Committee for Chemistry said in a cited statement. from Reuters.
“Researchers believe that in the future they will be able to contribute to flexible electronics, small sensors, thinner solar cells and encrypted quantum communications.”
Nanoparticles and quantum dots are used in LED lights and can also be used to guide surgeons when removing cancerous tissue. The more than century-old prize was awarded by the Royal Swedish Academy of Sciences and is worth 11 million Swedish kronor ($997,959).
On Wednesday, the academy appeared to accidentally publish the names of three scientists said to have won this year’s Nobel Prize in chemistry.
Bawendi is a professor at the Massachusetts Institute of Technology (MIT), Brus is a professor emeritus at Columbia University, and Ekimov works for Nanocrystals Technology Inc. Brus was hired by AT&T Bell Labs in 1972 where he spent 23 years, devoting much of his time to studying nanocrystals.
Bawendi was born in Paris and raised in France, Tunisia and the United States. Bawendi conducted postdoctoral research with Brus and then joined MIT in 1990 and became a professor in 1996.
Announcement
Ekimov was born in the Soviet Union, worked at the Vavilov State Optical Institute before moving to the United States. In 1999, Ekimov was named chief scientist at Nanocrystals Technology Inc. The Nobel Prize in chemistry is the third prize awarded this year following those for medicine and physics announced earlier this week.
Established by the Swedish inventor and chemist of dynamite Alfred Nobel, the prize for merit in the fields of science, literature and peace has been awarded since 1901 with some interruptions, mainly due to the world wars. This economic reward is also financed by the Swedish central bank.
Although the Chemistry Prize is sometimes overshadowed by the Physics Prize and its famous winners such as Albert Einstein, Chemistry Prize winners include many great scientists, including radioactivity pioneer Ernest Rutherford and Marie Curie, who also won the physics prize.
Awards on the field chemistry last year it was awarded to scientists Carolyn Bertozzi, Morten Meldal and Barry Sharpless for pioneering work in the field of “click chemistry,” which discovered reactions that allow molecules to come together to produce new compounds.
