Rheological signatures of a glass-glass transition in an aging colloidal clay
Roberta Angelini, Domenico Larobina, Barbara Ruzicka +2
The occurrence of non-equilibrium transitions between arrested states has recently emerged as an intriguing issue in the field of soft glassy materials. The existence of one such t…
Non-diffusive dynamics in a colloidal glass: aging versus rejuvenation
Roberta Angelini, Barbara Ruzicka
The microscopic dynamics of spontaneously aged and rejuvenated glassy Laponite is investigated through X-ray photon correlation spectroscopy. Two different behaviours of the intens…
Aging behavior of the localization length in a colloidal glass
R. Angelini, A. Madsen, A. Fluerasu +2
The localization length r_{loc} associated with a fast secondary relaxation in glassy Laponite is determined by X-ray photon correlation spectroscopy (XPCS) through a Debye-Waller…
Structural and microscopic relaxations in a colloidal glass
Flavio Augusto de Melo Marques, Roberta Angelini, Emanuela Zaccarelli +4
The aging dynamics of a colloidal glass has been studied by multiangle Dynamic Light Scattering, Neutron Spin Echo, X-ray Photon Correlation Spectroscopy and Molecular Dynamics sim…
Dichotomic Aging Behaviour in a Colloidal Glass
Roberta Angelini, Laura Zulian, Andrei Fluerasu +3
An unexpected dichotomic long time aging behaviour is observed in a glassy colloidal clay suspension investigated by X-Ray Photon Correlation Spectroscopy and Dynamic Light Scatter…
Structural and Microscopic Relaxation Processes in Liquid Hydrogen Fluoride
R. Angelini, P. Giura, G. Monaco +3
The high frequency collective dynamics of liquid hydrogen fluoride is studied by inelastic x-ray scattering on the coexistence curve at T = 239 K. The comparison with existing mole…
