Harvard researchers claimed last month that they had managed to create metallic hydrogen that has the capability to superconduct electricity at room temperature without resistance in a process that used massive amounts of pressure and a diamond vice. Stored at minus 193 degree celsius, the sample mysteriously disappeared, leaving researchers wonder whether it just evaporated. But they are determined to ...

Nobel Prize for chemistry 2011 goes to Israeli scientist Daniel Shechtman

The Nobel prize for chemistry has gone to Daniel Shechtman, from the Israel Institute of Technology, for his discovery of the structure of quasicrystals. Shechtman first created quasicrystals by rapidly cooling molten metals, such as aluminium and manganese, by squirting the mixture onto a cool surface. Then, he observed that the new crystal was made up of perfectly ordered, non-repeating ...
