Researchers from the University of Basel have reported a new method that allows the physical state of just a few atoms or molecules within a network to be controlled. It is based on the spontaneous self-organization of molecules into extensive networks with pores about one nanometer in size. In the journal 'small', the physicists reported on their investigations, which could be of particular importance for the development of new storage devices.

Around the world, researchers are attempting to shrink data storage devices to achieve as large a storage capacity in as small a space as possible. In almost all forms of media, phase transition is used for storage. For the creation of CD, for example, a very thin sheet of metal within the plastic is used that melts within microseconds and then solidifies again. Enabling this on the level of atoms or molecules is the subject of a research project led by researchers at the University of Basel.
