The 2023 Nobel Prize in Chemistry has been awarded to Moungi G. Bawendi, Louis E. Brus and Alexei I. Ekimov for the discovery and synthesis of quantum dots, the Royal Swedish Academy of Sciences said in Stockholm.
Two American scientists and a Russian have been awarded the 2023 Nobel prize in chemistry for the discovery and synthesis of quantum dots, which helped drive a revolution in nanotechnology.
Bawendi is an American chemist of French and Tunisian descent, based at MIT, Lewis E. Bruce, Professor at Columbia University and Ekimov is chief scientist at Nanocrystals Technology, a New York-based company.
The prize is shared equally between Moungi Bawendi, Louis Brus and Alexey Ekimov for discoveries on the unique properties of nano-materials, and how to make them, that paved the way for wide-ranging applications in consumer electronics, biochemistry and medicine.
Nanoparticles and quantum dots are used in LED-lights and TV-screens and can also be used to guide surgeons while removing cancer tissue, among other things.

The diagram below represents a road network connecting five towns, namely Meeren, Lannisport, Winterfell, Oldtown, and Gulltown. The maximum speed limits along any stretch of road are as shown in the diagram. The straight road that connects Meeren to Gulltown passes through Oldtown. Another straight road, running west to east, connecting Meeren to Winterfell, passes through Lannisport. Further, two straight roads, one from Lannisport to Oldtown and another from Winterfell to Gulltown, are perpendicular to the road joining Meeren to Winterfell, and run from south to north.
Consider a car always travelling at the maximum permissible speed, and always taking the shortest route. It takes 1 hour to reach Oldtown from Meeren, 2 hours to reach Gulltown from Oldtown, and 45 minutes to reach Winterfell from Gulltown. (For this problem, always consider the shortest route in terms of distance.)
The plots below depict and compare the average monthly incomes (in Rs. ’000) of males and females in ten cities of India in the years 2005 and 2015. The ten cities, marked A-J in the records, are of different population sizes. For a fair comparison, to adjust for inflation, incomes for both the periods are scaled to 2025 prices. Each red dot represents the average monthly income of females in a particular city in a particular year, while each blue dot represents the average monthly income of males in a particular city in a particular year. The gender gap for a city, for a particular year, is defined as the absolute value of the average monthly income of males, minus the average monthly income of females, in that year.
