Dynamics studies by Neutron Scattering

The X-Ray and Neutron Science focus on understanding the dynamical properties of H-bonds in a variety of important materials.

Specific projects include:

  • Dynamics of water confined in concrete and clays
  • Dynamics of local anesthetics and cancer drugs that are encapsulated in various drugs delivery systems.
  • Time-resolved neutron spectroscopy and imaging to follow the hydration process and development of the porous structure of dental cements.
  • Polymorphism in molecular drugs using spectroscopy with DFT calculations.

Looking at our most recent publications it is possible to get a best flavor of our work:
