Specialized service:

  • Diffusion and flow experiments in simple and complex fluids and solids, in a wide range of temperatures and on a wide range of nuclei.
  • Electrophoretic NMR experiments.
  • Kinetic experiments with rapid mixing, temperature jump, or light excitation.
  • MRI experiments on a wide variety of technological (paper, tablets, batteries, etc) and geological (soil, clay, cement) systems.
  • NMR cryoporometry.
  • In collaboration of P&L Scientific Instrument Services, design and construction of custom-built NMR equipment, mainly for electrophoretic NMR.
  • Solid state structural and dynamical problems, at high and low temperature, in a broad range of nuclei.
