Stockholm—Three scientists were awarded the Nobel Prize in chemistry for their groundbreaking research on quantum dots. Moungi Bawendi from MIT, Louis Brus from Columbia University, and Alexei Ekimov from Nanocrystals Technology Inc. were recognized for their work on these minuscule particles, which have dimensions of just a few atoms. Quantum dots have unique electronic properties that influence their interaction with light, resulting in vibrant colors. They are widely used in various electronic devices, including LED displays.
The Royal Swedish Academy of Sciences, which announced the award in Stockholm, stated that quantum dots have diverse applications. They emit light that can assist surgeons in illuminating tumor tissue and catalyze chemical reactions. The Academy also highlighted the role of quantum dots in modern technology, where they provide bright light in television screens and LED lamps.
In a surprising turn of events, the names of the Nobel Prize winners were leaked by Swedish media before the official announcement. Hans Ellegren, the Secretary-General of the Royal Swedish Academy of Sciences, expressed regret over the incident and stated that they were investigating the cause of the premature release of information.
Heiner Linke, a Nobel Committee expert, confirmed the absence of any decision prior to the official announcement. He acknowledged that a press release, if issued prematurely, would have been a mistake.
The Nobel Prize selection process involves nominations from thousands of scholars around the world. After extensive deliberations by specialized committees, the Royal Swedish Academy of Sciences presents one or more proposals to the full academy for a vote. The confidentiality of the deliberations and the identities of the nominees are maintained for 50 years.
In addition to the chemistry prize, the physics prize was awarded to French-Swedish physicist Anne L’Huillier, French scientist Pierre Agostini, and Hungarian-born Ferenc Krausz for their pioneering research that provided a glimpse into the ultrafast behavior of spinning electrons. The motion of these electrons is fundamental to various scientific fields and technological advancements.
Previous recipients of the Nobel Prize in chemistry include Carolyn R. Bertozzi and K. Barry Sharpless from the United States, along with Morten Meldal from Denmark. They were acknowledged for their development of a technique for joining molecules together, enabling the exploration of cells, DNA mapping, and the design of targeted drugs for diseases such as cancer.
The Nobel season is now halfway complete, with the prizes in literature, peace, and economics yet to be announced. The Nobel Foundation increased the prize money by 10% this year, and winners receive a cash reward, an 18-carat gold medal, and a diploma at the award ceremonies in December.
