Positive Feedback Drives Sharp Swelling of Polymer Brushes near Saturation
Simon Schubotz, Eva Bittrich, Holger Merlitz +4
We resolve the Schröder paradox for PNiPAAm brushes, showing experimentally that swelling at 100\% relative humidity (RH) matches the liquid state. This occurs via a sharp increase…
Experimental and simulation study of resin infiltration in carbon fiber rovings
Dominik Burr, Rudi Reichenbächer, Christina Scheffler +2
Continuous-fiber-reinforced polymers are vital for lightweight structural applications, where fiber-matrix wetting critically influences composite performance. Understanding dynami…
How Microplastics cross the Buoyancy Barrier: A multi-scale Study
Thomas Witzmann, Anja F. R. M. Ramsperger, Hao Liu +12
Microplastics (MPs), though less dense than water, are frequently recovered from sediments in aqueous environments, indicating they can cross the buoyancy barrier. We quantify eco-…
Rheological Insights from the Oscillation Dynamics of Viscoelastic Sessile Drops
Peyman Rostami, Alfonso A. Castrejón-Pita, Günter K. Auernhammer
This study investigates the oscillation behavior of a sessile drop placed on a hydrophobic substrate subjected to vertical vibrations with varying frequencies and amplitudes. We ex…
Dynamic Wetting by Concentrated Granular Suspensions
Reza Azizmalayeri, Peyman Rostami, Thomas Witzmann +2
Many functional materials, such as paints and inks used in applications like coating and 3D printing, are concentrated granular suspensions. In such systems, the contact line dynam…
