Multiscale Experimental Evidence of a Transitory State in the HDA-LDA Transition in Alumino-sodo-silicate Glasses
Antoine Cornet, Thierry Deschamps, Sylvie Le Floch +2
The structural evolution with temperature of pure silica (SiO2), sodium-silicate (5Na2O-95SiO2, 10Na2O-90SiO2 and 25Na2O-75SiO2) and albite (15Na2O-15Al2O3-75SiO2) glasses previous…
X-ray photo-induced atomic motion in Phase Change Materials and conventional covalent chalcogenide glasses
Irene Festi, Antoine Cornet, Tomoki Fujita +10
X-ray Photon Correlation Spectroscopy (XPCS) enables direct access to atomic-scale dynamics in disordered materials, revealing both spontaneous and X-ray-induced relaxation process…
Emergence of multiple relaxation processes during low to high density transition in Au49Cu26.9Si16.3Ag5.5Pd2.3 metallic glass
Alberto Ronca, Antoine Cornet, Jie Shen +8
The existence of multiple amorphous states, or polyamorphism, remains one of the most debated phenomena in disordered matter, particularly regarding its microscopic origin and impa…
Linking the pressure dependence of the structure and thermal stability to α- and \b{eta}-relaxations in metallic glasses
Jie Shen, Antoine Cornet, Alberto Ronca +13
Glasses derive their functional properties from complex relaxation dynamics that remain enigmatic under extreme conditions. While the temperature dependence of these relaxation pro…
Break-down of the relationship between α-relaxation and equilibration in hydrostatically compressed metallic glasses
Antoine Cornet, Jie Shen, Alberto Ronca +20
Glasses encode the memory of any thermo-mechanical treatment applied to them. This ability is associated to the existence of a myriad of metastable amorphous states which can be pr…
On the interplay of liquid-like and stress-driven dynamics in a metallic glass former observed by temperature scanning XPCS
Maximilian Frey, Nico Neuber, Sascha Sebastian Riegler +16
Modern detector technology and highly brilliant fourth-generation synchrotrons allow to improve the temporal resolution in time-resolved diffraction studies. Profiting from this, w…
Structural modifications of GeO glass under high pressure and high temperature
Antoine Cornet, Remy Molherac, Bernard Champagnon +1
Vitreous GeO has been compressed at high temperature, to investigate the effect of thermal activation on the structural reorganization during compression. The measurements were…
Permanently densified SiO glasses: a structural approach
Christine Martinet, Assia Kassir-Bodon, Thierry Deschamps +4
Densified silica can be obtained by different pressure and temperature paths and for different stress conditions, hydrostatic or including shear. The density is usually the macrosc…
High-pressure X-ray photon correlation spectroscopy at fourth-generation synchrotron sources
Antoine Cornet, Alberto Ronca, Jie Shen +8
A new experimental setup combining X-Ray Photon Correlation Spectroscopy (XPCS) in the hard x-ray regime and a high-pressure sample environment is developed to monitor the pressure…
Directly observing atomic-scale relaxations of a glass forming liquid using femtosecond X-ray photon correlation spectroscopy
Tomoki Fujita, Yanwen Sun, Haoyuan Li +25
Glass forming liquids exhibit structural relaxation behaviors, reflecting underlying atomic rearrangements on a wide range of timescales. These behaviors play a crucial role in det…
