N2 - High-pressure offers the thrilling possibility to synthesize novel solids with unique optical, electronic, magnetic or thermo-mechanical properties that is currently a major challenge in materials science. Some of our recent high-pressure studies of glass-derived nanocrystalline composite using diamond anvil cell technology and synchrotron radiation based x-ray diffraction are presented. We synthesized and investigated pressure-induced transformations occurring in a heterophased, nano-architectured composite that consists of an amorphous matrix and embedded nanocrystals or quantum dots of gallium oxide. We discuss the observed phase transition occurring in the nanocrystals seeded in a host glass matrix and we compare their equation of state and bulk modulus with that of bulk gallium oxide crystals.
