Insulator becomes conductor at the push of a button


Ionic liquids are important in scientific research because they can apply a lot of charge over a surface. Leiden physicists have now found that the charging process of ionic liquids purely depends on opposite charges attracting each other. Chemical reactions are sometimes involved, but not essential. Hasan Atesci publishes his results in Annalen der Physik on October 10th and defends his PhD thesis on September 12th. Read more
