Three scientists in the United States won the Nobel Prize in chemistry Wednesday for their work on quantum dots — particles just a few atoms in diameter that...

The suspense surrounding the academy’s decision took an unusual turn when Swedish media reported the names of the winners several hours before the prize was announced.

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. After officially announcing the three winners, Secretary-General Hans Ellegren said the Swedish academy would investigation how the information got out in advance.

Asked about the leak, Bawendi said he didn’t know he’d been made a Nobel laureate until he was called by the academy.He said he was not thinking about the possible applications of his work when he started researching quantum dots. “It was ringing during the night, but I didn’t answer it because I’m trying to get some sleep, basically,” he told The Associated Press. He finally saw the news online when he got up around 6 a.m.Brus said he was glad to see recognition for the area of chemistry he practices. The practical applications of quantum dots, like creating the colors in flatscreen TVs, are something he was hoping for when he started the work decades ago,he said.
