Heterogeneous dynamics in a polymer solution revealed through measurement of ultraslow convection
Thomas P. Chaney, Samuel D. Marks, Dylan M. Ladd +9
Understanding solution-phase aggregation and dynamics in complex fluids is critical for material processing, yet widely used dynamic light scattering (DLS) fails for strongly atten…
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…
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…
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…
