New material resembling a metal nanosponge could reduce computer energy consumption

A nanoporous material has been developed based on a copper and nickel alloy, with a structure similar to that of a sponge with pores measuring the size of a millionth of a millimeter, which allows handling and storing information using very little energy. These nanosponges could be the base of new magnetic memories for computers and mobile phones with greater energy efficiency than those currently existing.
