Opis

The 27th Europhysics Conference on Macromolecular Physics focused on applications of scattering methods to the dynamics of polymer dense systems and covered Rayleigh-Brillouin scattering and photon correlation spectroscopy, quasi-elastic neutron scattering, holographic methods, real time X-ray and neutron scattering techniques as well as the treatment of theoretical models and computer simulations of polymer dynamics.
