Welcome to the Institute of Nanotechnology

We conduct fundamental and applied research with a focus on innovation in the fields of nanoscience and nanotechnology. Our scientists collaborate within the institute and with partners around the world across the disciplines of physics, chemistry, and materials science, as well as biology and medicine.

Liebig Fellowship and YIG Prep Pro for Oliver Townrow

Dr. Oliver Townrow will start his independent career at INT, funded by both the VCI Liebig Fellowship and the KIT YIG Prep Pro funded fellowship. The Townrow research group will utilise the direct method metal vapour synthesis (MVS) to target novel complexes containing metals across the periodic table in their zero-oxidation state. These will then be explored as soluble Single-Atom Sources to prepare functional organometallics.

Review on High-Entropy Materials applications

This review by a collaboration of INT scientists on the recent research on high-entropy materials highlights their emerging potential in energy and electronic applications, based mainly on the intrinsic features of the "cocktail effect" and the lattice distortions of these materials. The emphasis lies on ionic and covalent ceramic materials.

Cyclocenes - rings of organometallic sandwich structures

In organometallic chemistry, so-called sandwich complexes always displayed linear chain structures. Now researchers at the Karlsruhe Institute of Technology (KIT) and Philipps-Universität Marburg have formed multi-level sandwich complexes into nanoscale rings and named them  "cyclocenes". The work has been published in Nature.
