The Nobel Prize in Chemistry in 2023 was awarded to scientists Alexey Ekimov, Mungi Bavendi and Louis Bruce for the “discovery and synthesis of quantum dots.” This was reported by the press service of the Nobel Committee. 78-year-old Ekimov was born in the USSR, Bavendi is a native of France, Bruce is an American, but all three live in the USA and work at American universities.
“Quantum dots have many interesting and unusual properties. It is important to note that they have different colors depending on their size,” said Johan Aquist, chairman of the Nobel Committee on Chemistry.
The discoverer of quantum dots is Alexey Ekimov. His work was recognized in the USSR: in 1976, the scientist received the USSR State Prize for a series of works “Detection and study of new phenomena related to the optical orientation of electron and nuclei spins in semiconductors.” Bruce and Bawendi develop his ideas: quantum dots are currently used, for example, in LED lamps and television screens.
After the collapse of the USSR, Ekimov has lived and worked in the USA since 1999.
A few hours before the official announcement of the Nobel laureates in chemistry, the Royal Swedish Academy of Sciences sent out a letter in which it named the names of the prize winners. It is believed that the letter was sent by mistake, writes Reuters.
A day earlier, the Nobel Prize in Physics was awarded to scientists Pierre Agostini, Ferenc Krausz and Anne L’Houllier for “experimental methods for generating attosecond pulses of light to study the dynamics of electrons in matter.”
And the winners of the 2023 Medicine Prize were biochemists Katalin Kariko and Drew Weissman, whose research on the development of messenger ribonucleic acid (mRNA) formed the basis for the creation of drugs for COVID-19. The most famous of them are vaccines from Moderna and Pfizer.
In 2022, the Nobel Prize in Chemistry was awarded to American scientists Caroline Bertozzi and Barry Sharpless, as well as Dane Morten Meldahl “for the development of click chemistry and bioorthogonal chemistry methods.”
