The main research fields of the Institute are as follows:

  • nanostructured materials,
  • self-assembled nanolayers,
  • surface characterization and modification,
  • heterogeneous catalytic reactions.

The main aspects of the research strategy in the nanoscience field are as follows:

  • novel approaches of nano-sized particles and layers by surface and interface characterization,
  • modeling uniform nano-systems by sophisticated surface spectroscopy of molecular level for understanding the active surface,
  • elucidation of surface reaction pathways for the modification of certain properties (e.g., smart coatings).

Creating nanostructuring surfaces and nanostructured coatings and interfaces in films using top-down and bottom-up processes offers great potential for designing and developing next generation materials and structures for applications. One of the main challenges in this area is to devise strategies that integrate nano-scale superstructures (e.g., nanoparticles, nanotubes) and their assemblies with conventional technologies via traditional and newly evolving variants of techniques such as vapor deposition, laser alloying, and combinatorial approaches.

The chemistry and physics of surfaces and interfaces are among the most challenging and exciting areas of condensed matter science. Moreover, advances in the technology of surface modification have a fundamental impact on industries in diverse fields such as telecommunications, petroleum, superconductivity, computer science, minerals, and chemicals.

Self-assembled monolayers (SAMs) on organic interfaces provide a unique link between the science of organic surfaces and technologies. SAMs are model systems for the study of organic and biological interfaces and are of technical interest for the fabrication of sensors, transducers, protective layers, and for lubrication, and as patternable materials.

Research on heterogeneous catalysts is focused on the knowledge about the optimum surface restructuring that is necessary for the stability of the active sites, functionalizing the surface and development of multi-functional catalysts.

The main fields are as follows:

  • modification of the nano-environment in catalytically active materials,
  • low temperature oxidation,
  • heterogeneous catalytic activation of carbonyl compounds,
  • asymmetric heterogeneous catalysis.

Catalytic materials studied are:

  • supported nano-structured mono- and multi-metallic clusters,
  • anchored metal complexes,
  • multicomponent metal oxides,
  • micro- and mesoporous materials.

High-throughput experimentation and combinatorial material science for the preparation and testing of different new catalytic materials are preferably applied.
