CHEMISTRY NOBEL AWARDED TO 3 SCIENTISTS FOR WORK WITH QUANTUM DOTS

Nobel Prize in Chemistry to Moungi G. Bawendi, Louis E. Brus and Alexei I. Ekimov “for the discovery and synthesis of quantum dots.

Wed 04 October 2023:

The Nobel Prize in Chemistry for Chemistry was awarded to researchers Moungi Bawendi, Louis Brus, and Alexei Ekimov for “the discovery and synthesis of quantum dots,” which illuminate televisions and computer monitors and are used by doctors to map tumors.

“The Nobel Laureates … have succeeded in producing particles so small that their properties are determined by quantum phenomena. The particles, which are called quantum dots, are now of great importance in nanotechnology,” the Nobel Committee for Chemistry said in a statement on Wednesday.

“Researchers believe that in the future they could contribute to flexible electronics, tiny sensors, thinner solar cells and encrypted quantum communication.”

Nanoparticles and quantum dots are used in LED lights and can also be used to guide surgeons while removing cancer tissue.

In a highly unusual turn of events, Swedish media reported the names of the winners before the prize was announced.

The academy did not comment on the leaked names before the announcement.

On Tuesday, Pierre Agostini, Ferenc Krausz and Anne L’Huillier have won the 2023 Nobel Prize in physics for “experimental methods that generate attosecond pulses of light for the study of electron dynamics in matter”, the award-giving body says.

“The laureates’ experiments have produced pulses of light so short that they are measured in attoseconds, thus demonstrating that these pulses can be used to provide images of processes inside atoms and molecules,” the award-giving body said in a statement on Tuesday.

The more than century-old prize is awarded by the Royal Swedish Academy of Sciences and is worth 11 million Swedish crowns ($997,959).
