Nobel win for crystal find
Stockholm, Oct. 5 (Reuters): An Israeli scientist whose work was once ridiculed for being out of line with received thinking won the 2011 Nobel Prize for chemistry today for discovering different ways in which atoms could be packed together in solid materials.
The work of Daniel Shechtman, the winner of the prize of 10 million Swedish crowns ($1.5 million), has opened the door for experiments in the use of the quasicrystals, which he discovered, in everything from diesel engines to frying pans.
Shechtman found in 1982 that atoms in crystals could be packed in a pattern which did not repeat itself — recalling the intricate mosaics of Arab art and flying in the face of the accepted view that patterns had to be repetitious.
"His discovery was extremely controversial. In the course of defending his findings, he was asked to leave his research group," said the Nobel Committee for Chemistry at the Royal Swedish Academy of Sciences, which made the award.
"However, his battle eventually forced scientists to reconsider their conception of the very nature of matter," it added in a statement. "Scientists are currently experimenting with using quasicrystals in different products such as frying pans and diesel engines." .........
David Phillips, president of Britain's Royal Society of Chemistry, said: "Quasicrystals ... break all the rules of being a crystal at all. You can normally explain in simple terms where in a crystal each atom sits — they are very symmetrical.
"With quasicrystals, that symmetry is broken: there are regular patterns in the structure, but never repeating.
"They're quite beautiful, and have potential applications in protective alloys and coatings. The award of the Nobel Prize to Danny Shechtman is a celebration of fundamental research."
