In 2008 a team of physicists from Argonne National Laboratory, in Illinois, and other institutions stumbled upon an odd phenomenon. They called it superinsulation, because in many ways it was the opposite of superconductivity<\/a>. Now they\u2019ve worked out the theory behind it, potentially opening the doors to better batteries, supersensitive sensors, and strange new circuits.<\/p>\n

Superconductors lose all resistance once they fall below a certain temperature. In superinsulators, on the other hand, the resistance to the flow of electricity becomes infinite at very low temperatures, preventing any flow of electric current.<\/p>\n

Valerii Vinokur of Argonne and Tatyana Baturina from the Institute of Semiconductor Physics, in Novosibirsk, Russia, discovered superinsulators when the pair chilled a thin film of titanium nitride to nearly absolute zero and tried to send a current through it. They found that the resistance shot up to 100 000 times its original level. The effect vanished at higher temperatures. The researchers also noticed that the effect was sensitive to the strength of a magnetic field; as they increased the strength of an external magnetic field, the resistance disappeared.<\/p>\n<\/blockquote>\n
