Three scientists based in the U.S. won the Nobel Prize in chemistry Wednesday for their work on quantum dots — tiny particles just a few atoms in diameter that can release very bright colored light and whose applications in every day life include electronics and medical imaging, AP reported.
Moungi Bawendi, of MIT; Louis Brus, of Columbia University; and Alexei Ekimov, of Nanocrystals Technology Inc., were honored for their work with the particles that “have unique properties and now spread their light from television screens and LED lamps,” according to the Royal Swedish Academy of Sciences, which announced the award in Stockholm.
“They catalyze chemical reactions and their clear light can illuminate tumor tissue for a surgeon,” the academy said.
Quantum dots' electrons have constrained movement, which affects how they absorb and release visible light, allowing for very bright colors.
The dots are nanoparticles that glow blue, red, or green when illuminated or exposed to light. The color they emit depends on the size of the particles. Larger dots shine red, and smaller dots shine blue. The color change is due to how electrons act differently in more or less confined spaces.
While physicists had predicted these color-change properties as early as the 1930s, creating quantum dots of specific controlled sizes was not possible in the lab for another five decades.
In a highly unusual leak, Swedish media reported the names of the winners before the prize was announced.
Ekimov, 78, and Brus, 80, are early pioneers of the technology recognized Wednesday, while Bawendi, 62, is credited with revolutionizing the production of quantum dots “resulting in almost perfect particles. This high quality was necessary for them to be utilized in applications,” the academy said.
90-year-old Artsakh woman reached the Armenian border town of Goris after Azerbaijan’s seizure of her country, hugged her son, whom she had not seen for almost one year, and died in his arms, reporter Siranush Sargsyan said.
“During Azerbaijan’s 9-month starvation siege, 90-year-old Aneshka kept going for one goal: to see her son again. Following Azerbaijan’s invasion, she made it to Goris, Armenia, hugged her son for the first time in nearly a year—and for the last time ever, passing away in his arms,” she wrote on X on Tuesday.

U.S. Senator Bob Menendez (D-N.J.), Chairman of the Senate Foreign Relations Committee, took to the Senate floor on Monday to warn that Azerbaijan's blockade of Artsakh has all the hallmarks of genocide and pledged to hold Azerbaijan accountable.
The senator called on the Biden Administration to enforce Section 907 and stop all security assistance to Azerbaijan. He went on to call for sanctions against the Aliyev regime for war crimes and ethnic cleansing, ANCA reported.
"To the men organizing and carrying out this brutal campaign, we will hold you accountable for your crimes, even if it takes a lifetime – you will pay a price, you will face justice – and I certainly will not rest until you do so,” stated Menendez.
