Welcome to the Institute for Materials and X-Ray Physics at Hamburg University of Technology (TUHH), Germany


Illustration of our research topics
 
We conduct fundamental research in condensed matter physics and novel functional materials. We experimentally explore the multi-scale interplay of structure, dynamics and function of matter, benefiting from the vibrant and inspiring natural, materials and X-ray science environment of the Hamburg metropolitan area, including the Hamburg University, the Helmholtz-Zentrum Hereon and the Deutsche Elektronen-Synchrotron DESY. Our Institute for Materials and X-Ray Physics (M-2) at the Hamburg University of Technology (TUHH) is linked to DESY via a joint research group for high-resolution X-ray analytics of materials. We are a member of the Centre for Molecular Water Science CMWS and the Collaborative Research Centre CRC 986 “Tailor-Made Multi-Scale Materials Systems”. Our research projects focus on how condensed matter behaves in extreme spatial confinement, especially in nanoporous media, and how this fundamental knowledge can be used for the design and fabrication of advanced materials.

Please feel invited to read more about our research activities, to browse our publication list or to get an impression of our group life (group members & alumni and events).

At present our main efforts are directed towards an understanding of:

 
  • Self-assembly, phase transitions, and dynamics of soft molecular condensed matter in geometrical confinement.
 
  • Adsorption-induced deformation and elastocapillarity upon condensation of liquids in porous media, most prominently hierarchical porous silicon and silica.
 
  • Fluid transport and rheology of liquids in porous media, in particular in nanoporous solids (Nanofluidics).

  • Design principles for mechanical, fluidic and photonic metamaterials based on combinations of porous solids with functional soft molecular fillings (electrolytes, (bio-)polymers, liquid crystals). 

 

 

 
  • The fundamental structural and statistical properties of fluid interfaces, that is the relationship between the thermodynamics, the microscopic structure of these interfaces and their microscopic and macroscopic hydrodynamics.
