This page gives an overview on the research topics covered in the division of Applied Magnetic Resonance and introduces the scientitic infrastructure available for the group members.

Nuclear magnetic resonance (NMR) is a versatile experimental method with very broad spectrum of applications ranging from elucidating structure of molecules and materials to assessing molecular motion on the time scale from nanoseconds to seconds and to non-invasive imaging of human body. Among them, direct measurement of translational motion using the pulsed field gradient technique of NMR is of special relevance. The chaotic Brownian motion is an ubiquitous phenomenon in nature and is of key importance in biosciences, chemical engineering, environmental sciences, etc. In our group, magnetic resonance is used to cover very different aspects of this phenomenon. Another focus is on establishing the structure of porous solids from ordered MOFs to disordered glasses.

The focus research areas in our group include among others:

  • Diffusion in hierarchically-structured porous solids
  • Understanding phase state and dynamics in mesoporous solids
  • NMR in spatially random magnetic field
  • Microscopic insight into MRI contrast
  • Unreveling the structrure of porous solids
