Non-simple flow behavior in a polar van der Waals liquid: structural relaxation under scope
Silvia Arrese-Igor, Angel Alegria, Juan Colmenero
The non-exponential character of the structural relaxation is considered one of the hallmarks of the glassy dynamics and in this context, the singular shape observed by dielectric…
Self-propelling colloidal finite state machines
Steven van Kesteren, Laura Alvarez, Silvia Arrese-Igor +2
Endowing materials with physical intelligence holds the key for a progress leap in robotic systems. In spite of the growing success for macroscopic devices, transferring these conc…
Partition of Coating Agents between Nanoparticle Interfaces and the Polymer in Nanocomposites
Dafne Musino, Julian Oberdisse, Michael Sztucki +2
Industrial and model polymer nanocomposites are often formulated with coating agents to improve polymer-nanoparticle (NP) compatibility. Here the localization of silane coating age…
Reconfigurable Artificial Microswimmers with Internal Feedback
L. Alvarez, M. A. Fernandez-Rodriguez, A. Alegria +4
Micron-size self-propelling particles are often proposed as synthetic models for biological microswimmers, yet they lack internally regulated adaptation, which is central to the au…
Reaching the ideal glass transition by aging polymer films
Virginie M. Boucher, Daniele Cangialosi, Angel Alegria +1
Searching for the ideal glass transition, we exploit the ability of glassy polymer films to explore low energy states in remarkably short time scales. We use 30 nm thick polystyren…
Anomalous Molecular Weight Dependence of Chain Dynamics in Unentangled Polymer Blends with Strong Dynamic Asymmetry
Silvia Arrese-Igor, Angel Alegria, Angel J. Moreno +1
We address the general question of how the molecular weight dependence of chain dynamics in unentangled polymers is modified by blending. By dielectric spectroscopy we measure the…
