Nanotechnology will surely change laptops and other electronic devices in the upcoming few years and it is very difficult to predict about laptops of tomorrow. It may weigh only ounces and operate for weeks on a single charge. Some manufacturers are also designing a totally different chassis from present flat, grey or black box.

IBM has declared 2 key scientific accomplishments in the field of nanotechnology that could give new types of structures constructed from a few molecules or atoms. Though these researches are far from using them into products, they will definitely enable scientists at IBM and elsewhere to promote the field of nanotechnology which can be defined as the exploration of building structures and devices out of ultra-tiny, atomic-scale components.

Such devices may be used as upcoming storage devices, computer chips, sensors and for applications which are beyond imagination. The journal Science has published two reports of these researches on 1 Sept, 2007.

In the first report, IBM scientists explain major progress in adding a property called magnetic anisotropy in the atoms. This basic measurement has significant technological effects as it decides an atom’s ability to store information. Up to this time, none had been able to calculate the magnetic anisotropy of an atom.

With further effort, it may build structures containing small clusters of atoms or individual atoms that could store magnetic information. A storage capability would make possible the total content of YouTube having millions of videos (trillion bits of data) to fit in an iPod-sized device. Maybe the breakthrough could lead to new kinds of very small devices and could be applied to entire new disciplines beyond traditional computing.

In the second report, IBM researchers revealed the 1st single molecule switch which can work perfectly without upsetting the molecule’s outer frame. This is very important step towards constructing computing elements at the molecular scale which are faster, smaller and utilize less energy than present memory devices and chips.

Besides switching within a single molecule, the researchers also showed that atoms can be used to switch atoms in a neighboring molecule, representing a basic logic element. This is possible partly as the molecular framework is not disrupted.
