Stockholm, October 4, 2023 — The Royal Swedish Academy of Sciences has decided to award the Nobel Prize in Chemistry 2023 to Moungi G. Bawendi, Massachusetts Institute of Technology (MIT), Cambridge, MA, USA; Louis E. Brus, Columbia University, New York, NY, USA; and Alexei I. Ekimov, Nanocrystals Technology Inc., New York, NY, USA “for the discovery and synthesis of quantum dots.”
The Nobel Prize in Chemistry 2023 rewards the discovery and development of quantum dots, nanoparticles so tiny that their size determines their properties. These minor nanotechnology components now spread their light from televisions and LED lamps and can also guide surgeons when they remove tumor tissue, among many other things.
Everyone who studies chemistry learns that an element’s properties are governed by how many electrons it has. However, when matter shrinks to nano-dimensions, quantum phenomena arise; the size of the matter regulates these. The Nobel Laureates in Chemistry 2023 have succeeded in producing particles so small that quantum phenomena determine their properties. The particles, called quantum dots, are now crucial in nanotechnology.
“Quantum dots have many fascinating and unusual properties. Importantly, they have different colors depending on their size,” says Johan Ã…qvist, Chair of the Nobel Committee for Chemistry.
Quantum dots now illuminate computer monitors and television screens based on QLED technology. They also add nuance to the light of some LED lamps, and biochemists and doctors use them to map biological tissue.
Quantum dots are thus bringing the most significant benefit to humankind. Researchers believe that in the future, they could contribute to flexible electronics, tiny sensors, thinner solar cells, and encrypted quantum communication. So, we have just started exploring the potential of these tiny particles.

G20 Leaders look forward to Paris 2024 “as a symbol of peace” and “with the participation of all.”
New Delhi, October 3, 2023 — The Heads of State and Heads of Government of the G20, who met in New Delhi, India, declared their strong support for the Olympic Games Paris 2024. India currently holds the G20 Presidency with Prime Minister Narendra Modi.
The G20 New Delhi Leaders’ Declaration said: “We reiterate our commitment to the G20 as the premier forum for global economic cooperation and its continued operation in the spirit of multilateralism, based on consensus, with all members participating on an equal footing in all its events including Summits.”
It continued: “We also look forward to the Paris Olympic and Paralympic Games in 2024 as a symbol of peace, dialogue amongst nations, and inclusivity, with participation of all.”
IOC (International Olympic Committee) President Thomas Bach welcomed the statement. He said in Lausanne: “We would like to thank very warmly the G20 Leaders, who include the African Union for the first time, for their invaluable support. The IOC will continue to work with full commitment to achieve these goals, which are also our goals.”
The Group of Twenty (G20) comprises 19 countries (Argentina, Australia, Brazil, Canada, China, France, Germany, India, Indonesia, Italy, Japan, the Republic of Korea, Mexico, Russia, Saudi Arabia, South Africa, Türkiye, the United Kingdom and the United States), the African Union (AU) and the European Union (EU). The G20 members represent around 85 percent of the global GDP, over 75 percent of international trade, and about two-thirds of the world’s population.
