The addition of synchrotron radiation based techniques has now extended the kind of information that can be extracted to include thermoelastic properties like sound velocity, vibrational specific heat, absolute value of atomic displacement, and phonon density of states.

Furthermore, experiments under extreme conditions of temperature and pressure have now become common. With its unique depth and breadth, Mössbauer spectroscopy and nuclear resonant scattering of synchrotron radiation will continue to provide detailed understanding of physical, chemical, biological, and geological processes, earthly and extra-terrestrial alike. We plan to bring researchers from these diverse fields together for a two days symposium, and provide a chance to meet with each other in a formal and informal setting.
