Best of 2012: Room Temperature Superconductivity Found in Graphite Grains
In September, a team from Germany claimed to have found evidence that water-soaked grains of carbon superconduct at room temperature
Here’s an interesting recipe. Take a spoonful of graphite powder and stir it into a glass of water. Leave for 24 hours at room temperature and then filter the powder. Finally, bake overnight at 100 degrees C and allow to cool.
And voila! A material that superconducts at over 300 kelvin–room temperature. At least that’s the claim today from Pablo Esquinazi and buddies at the University of Leipzig in Germany.
