Exploitable results Dynamics of glass formation and low-temperature anomalies in strong and fragile glasses The influence of the nanostructure in disordered solids on their dynamical properties is a question which has been intensively discussed over the last few years. The purpose of the present project is the analysis of vibrational and relaxational dynamics of glasses, glass forming melts and nanocrystals dispersed in glasses. Applying light scattering, nuclear magnetic resonance and dielectric relaxation spectroscopy will cover excitation frequencies ( in the range 0.01 Hz < ( < 10 THz and a temperature range which includes the glassy state and the regime above the glass transition temperature Tg. The relation of vibrational versus relaxational dynamics and the relation among the different relaxational contributions will be investigated in order to clarify the scenario of the glass transition. It will specify the connection with the degree of fragility and with the heat capacity change observed at Tg. The results gathered here (T > Tg) will be related to the lowtemperature anomalies of glasses; they will also be compared with the analysis of experiments investigating the static structure, namely X-ray and synchrotron radiation techniques. The systems to be investigated are high and low molecular weight glassformers. In particular, the molecular weight dependencies will be studied. Searching for OpenAIRE data...
