In a collaboration with Bernard Champagnon’s research group at the Laboratoire de Physico-Chimie des Matériaux Luminescents, Université Lyon 1, we have been performing in-situ small angle X-ray scattering experiments at the European
Synchrotron Radiation Facility (ESRF). The aim of the study is to demonstrate the dependence of structural heterogeneity of various glasses on fictive temperature and fictive pressure (e.g. S. Reibstein, et al.,
J. Chem. Phys 134, 204502). This work is financially supported by DFG, DAAD, BFHZ and ESRF.
