A scanning tunneling microscope in Abhay Pasupathy’s lab used to measure the chemical properties of graphene. The tall cylindrical component on the right is a cryogenic chamber used to keep the ultra-strong carbon material at a temperature of minus-450 degrees Fahrenheit. Top left inset: A color-coded image of electrons around a nitrogen atom (red) embedded in the honeycomb-like surface of graphene (blue).

In a soundproof room in Pupin Hall, a futuristic-looking metallic apparatus is creating three-dimensional images of a material that may one day power a new generation of smaller and faster electronic devices.
