The electron slow motion: Ion physics on the femtosecond scale
When ions penetrate a material, highly complex processes take place - so fast that they could hardly be analyzed until now. But sophisticated measurements have now made it possible. How do different materials react to the impact of ions? This is a question that plays an important role in many areas of research - for example in nuclear fusion research, when the walls of the fusion reactor are bombarded by high-energy ions, but also in semiconductor technology, when semiconductors are bombarded with ion beams to produce tiny structures.

Impossible material made possible inside a graphene sandwich
Impossible material made possible inside a graphene sandwich
Atoms bind together by sharing electrons. The way this happens depends on the atom types but also on conditions such as temperature and pressure. In two-dimensional (2D) materials, such as graphene, atoms join along a plane to form structures just one atom thick, which leads to fascinating properties determined by quantum mechanics.

New State of Matter: Crystalline and Flowing at the Same Time
Through their research efforts, the team was able to finally disprove an intuitive assumption that in order for two particles of matter to merge and form larger units (i.e. aggregates or clusters), they must be attracted to each other. As early as the turn of the century, a team of soft matter physicists headed by Christos Likos of the University of Vienna predicted on the basis of theoretical considerations that this does not necessarily have to be the case.
