Glass–glass transition during aging of a colloidal clay
Roberta Angelini,Emanuela Zaccarelli,Flavio Augusto de Melo Marques,Michael Sztucki,Andrei Fluerasu,Giancarlo Ruocco,Giancarlo Ruocco,Barbara Ruzicka +7 more
TL;DR: Evidence of a spontaneous glass-glass transition in a colloidal clay is provided and may have implications for heterogeneously charged systems out-of-equilibrium and for applications where a fine control of the local order and/or long term stability of the amorphous materials are required.
Journal ArticleDOI
Slow dynamics and aging in colloidal gels studied by x-ray photon correlation spectroscopy.
TL;DR: Slow, nonequilibrium dynamics during delayed sedimentation in a colloidal depletion gel was studied by x-ray photon correlation spectroscopy, indicating a jamming transition toward full aging.
Journal ArticleDOI
Many-body hydrodynamic interactions in charge-stabilized suspensions.
Adolfo J. Banchio,Jacek Gapiński,Adam Patkowski,Wolfgang Häußler,Andrei Fluerasu,Stefano Sacanna,P. Holmqvist,G. Meier,M. Paul Lettinga,Gerhard Nägele +9 more
TL;DR: Using x-ray photon correlation spectroscopy, the hydrodynamic function H(q) can be quantitatively described by means of a novel Stokesian dynamics simulation method for charged Brownian spheres, and by a modification of a many-body theory developed originally by Beenakker and Mazur.
Journal ArticleDOI
Dichotomic aging behaviour in a colloidal glass
Roberta Angelini,L. Zulian,Andrei Fluerasu,Anders Madsen,Giancarlo Ruocco,Giancarlo Ruocco,Barbara Ruzicka +6 more
TL;DR: In this paper, an unexpected dichotomic long time aging behavior is observed in a glassy colloidal clay suspension investigated by X-ray photon correlation spectroscopy and dynamic light scattering.
Journal ArticleDOI
X-Ray Intensity Fluctuation Spectroscopy Studies on Phase-Ordering Systems
TL;DR: The order-disorder phase transition in Cu3Au has been studied by x-ray intensity fluctuation spectroscopy and by using coherent scattering, the fluctuations about this universal scaling form are measured for a nonconserved system.
