College 5a

Crystallography

College Secretary: Thomas Hansen
Mailing list: col05a_l@ill.eu

College 5a studies crystallography, in a broad sense, both via single crystal and powder diffraction. Some structural studies may require small angle scattering as well. In contrast to college 5b, dedicated to magnetic structure, college 5a is dedicated to the nuclear, the non-magnetic aspect of structure. The influence of crystallographic structure is omnipresent: the properties of water and ice, the hardness of metals, the strength of magnets, and even the biology of DNA or the effect of antibodies on viruses – all depend on structure.

The main instruments used for College 5a proposals are:

If you want to come to the ILL and give a seminar, please apply to Thomas Hansen
He can schedule a seminar at the ILL any time (best on Monday and Wednesday, 11h00 or 14h00).
Travel and expenses for your stay may be reimbursed. Do not hesitate  if you are coming for an experiment in Grenoble (ILL, ESRF, EMBL, CEA, CNRS, ...).

Single Crystal Diffraction

  • 5-11 Inorganic structures
  • 5-12 Organic compounds and metallo-organic complexes
  • 5-13 Crystalline short-range order (diffuse scattering, plastic phases, liquid crystals)
  • 5-14 Functional materials (including superconductors, mixed-valence compounds, heavy-fermion compounds, low-dimensional systems…)
  • 5-15 Structural studies of phase transitions, pressure-dependence, superstructures, incommensurate structures, quasicrystals, texture analysis
  • 5-16 Physical properties of single-crystal diffraction (anomalous scattering, extinction, TDS analysis, topography, interferometry…)

Powder Diffraction

  • 5-21 Small structures: inorganics, organics, minerals
  • 5-22 Large structures and defect structures (zeolites, clathrates, mesoporous materials, intercalates, catalysts, solid electrolytes, hydrides and hydrogen storage, oxygen confined materials, quasicrystals …)
  • 5-23 Functional materials (including superconductors, mixed-valence compounds, heavy-fermion compounds, low-dimensional systems…)
  • 5-24 Structural studies of phase transitions, effects of temperature and pressure
  • 5-25 Chemical kinetics, thermodiffractometry, thermal expansion
  • 5-26 Defects and atomic disorder in crystals (diffuse scattering)
