Copper and Nickel alloy has provided base to the newly developed nanoporous material. It has a structure similar to a sponge with so many pores. Its size has been measured as millionth of a millimeter. Minimum use of energy is done in handling and storing the information.
The efficient nanosponges can provide foundation to the new magnetic memories for computers and mobile phones. Nanosponges will have better energy efficiency in terms of those which are currently in use. Today, if we see practically, 40 per cent of electrical energy going into computers (“Big Data” servers) is lost as heat. French scientists in 2007 analyzed that magnetic materials kept in ultra-thin layers and voltage is applied, the amount of current and energy pointing magnetic domains got reduced by 4 %. The minute reduction was not helpful enough to be applied to devices.
A team of researchers looked out for a solution based on magnetic properties of this new nanoporous material that could increase the surface. Thus, it provided a new paradigm to save energy of computers.
