Solid and liquid at the same time

Microscopically small particles can spontaneously self-assemble into complex layered structures with remarkable properties, according to calculations performed at the TU Wien. There are many ways to create new, innovative materials. One of the most interesting is a process whereby tiny particles self-assemble to form complex structures. This process, referred to as 'self-organisation', opens up some remarkable opportunities as has now been demonstrated by computer simulations performed at TU Wien. Simple macromolecules are able to form layered systems that can be simultaneously solid and liquid within a wide temperature range. Repulsive and attractive charges - 'The basic concept is one that is exploited widely in nature,' explains Professor Gerhard Kahl of the Institute of Theoretical Physics at TU Wien. 'Viruses and bacteria often exhibit surface charges.
