Surface mobility of a glass-forming polymer in an ionic liquid
Xinyu Zhang, Christian Pedersen, Haoqi Zhu +6
The free surface of glassy polymers exhibits enhanced segmental dynamics compared to the bulk, forming a liquid-like layer that lowers the glass transition temperature (Tg) in nano…
Bidirectional Mamba state-space model for anomalous diffusion
Maxime Lavaud, Yosef Shokeeb, Juliette Lacherez +2
Characterizing anomalous diffusion is crucial in order to understand the evolution of complex stochastic systems, from molecular interactions to cellular dynamics. In this work, we…
Taylor's swimming sheet near a soft boundary
Aditya Jha, Yacine Amarouchene, Thomas Salez
In 1951, G.I. Taylor modeled swimming microorganisms by hypothesizing an infinite sheet in 2D moving in a viscous medium due to a wave passing through it. This simple model not onl…
Swelling and evaporation determine surface morphology of grafted hydrogel thin films
Caroline Kopecz-Muller, Clémence Gaunand, Yvette Tran +5
We experimentally study the formation of surface patterns in grafted hydrogel films of nanometer-to-micrometer thicknesses during imbibition-driven swelling followed by evaporation…
On the bridge hypothesis in the glass transition of freestanding polymer films
Haggai Bonneau, Maxence Arutkin, Rainni Chen +3
Freestanding thin polymer films with high molecular weights exhibit an anomalous decrease in the glass-transition temperature with film thickness. Specifically, in such materials,…
Contactless Rheology of Soft Gels over a Broad Frequency Range
Zaicheng Zhang, Muhammad Arshad, Vincent Bertin +4
We report contactless measurements of the viscoelastic rheological properties of soft gels. The experiments are performed using a colloidal-probe Atomic Force Microscope (AFM) in a…
