This session will present recent advances on structural aspects of glass, including short and medium range order and heterogeneities. Contributions that cover basic glass characterization and correlation between glass structure and glass properties are welcome. Contributions include, but are not limited to, various experimental techniques such as X-ray, neutron, and light scattering; X-ray absorption and emission spectroscopy; vibrational spectroscopy; magnetic resonance spectroscopy; and scanning probe microscopy.
