Mesocrystals are a class of solids formed by the
regular arrangement of nanocrystals, which are tiny nanoparticles
that have unique properties due to their small size. In
mesocrystals, these take on a highly organized, superordinate form
in a densely packed grid. A German-Swiss research team led by
Professor Helmut Cölfen, a chemist from Konstanz, has now succeeded
in synthesizing particularly complex mesocrystals with largely
unknown chemical and physical properties and in shedding light on
their structure.
