This year's Nobel Prize for Chemistry has gone to American Richard Heck and Japanese researchers Ei-ichi Negishi and Akira Suzuki. The Prize was given to them for developing a chemical method that has allowed scientists to make medicines and better electronics.The Royal Swedish Academy of Sciences said today in Stockholm that the award honours their development of palladium-catalyzed cross couplings in organic systems. The tool has applications in a wide range of fields,from agriculture and pharmaceuticals to coatings for electronic components,like chip. The awards were established by Swedish industrialist Alfred Nobel – the inventor of dynamite – and are always handed out on December 10, the anniversary of his death in 1896.
