Polyelectrolyte adsorption at the solid-liquid interface favors receding contact line instability
Léa Delance, Diego Díaz, Arivazhagan G. Balasubramanian +3
Controlling the motion of non-Newtonian drops on surfaces is crucial for applications ranging from inkjet printing to biomedical devices and food processing. While the macroscopic…
Capillary filling of star polymer melts in nanopores
Jianwei Zhang, Jinyu Lei, Pu Feng +3
Topology of polymer profoundly influences on its behavior. However, its effect on imbibition dynamics remains poorly understood. In the present work, capillary filling (during imbi…
Global -dependent inverse transforms of intensity autocorrelation data
Tobias Eklund, Christina M. Tonauer, Felix Lehmkühler +1
We present a new analysis approach for intensity autocorrelation data, as measured with dynamic light scattering and X-ray photon correlation spectroscopy. Our analysis generalizes…
Topological comparison of flexible and semiflexible chains in polymer melts with -chains
Maurice P. Schmitt, Sarah Wettermann, Kostas Ch. Daoulas +2
A central paradigm of polymer physics states that chains in melts behave like random walks as intra- and interchain interactions effectively cancel each other out. Likewise, -ch…
Island formation in heteroepitaxial growth
Frederik Munko, Catherine Cruz Luukkonen, Ismael S. S. Carrasco +2
Island formation in strain-free heteroepitaxial deposition of thin films is analyzed using kinetic Monte Carlo simulations of two minimal lattice models and scaling approaches. The…
Convection can enhance the capacitive charging of porous electrodes
Aaron D. Ratschow, Alexander J. Wagner, Mathijs Janssen +1
Charge transport in porous electrodes is foundational for modern energy storage technologies like supercapacitors, fuel cells, and batteries. Supercapacitors in particular rely sol…
Smart polymer solution and thermal conductivity: How important is an exact polymer conformation?
Mokter M. Chowdhury, Robinson Cortes-Huerto, Debashish Mukherji
Heat management in devices is a key to their efficiency and longevity. Here, thermal switches (TS) are of great importance because of their ability to transition between different…
Wetting on Silicone Surfaces
Lukas Hauer, Abhinav Naga, Rodrique G. M. Badr +3
Silicone is frequently used as a model system to investigate and tune wetting on soft materials. Silicone is biocompatible and shows excellent thermal, chemical, and UV stability.…
Cloaking Transition of Droplets on Lubricated Brushes
Rodrique G. M. Badr, Lukas Hauer, Doris Vollmer +1
We study the equilibrium properties and the wetting behavior of a simple liquid on a polymer brush, with and without presence of lubricant by multibody Dissipative Particle Dynamic…
Dynamics of Droplets Moving on Lubricated Polymer Brushes
Rodrique G. M. Badr, Lukas Hauer, Doris Vollmer +1
Understanding the dynamics of drops on polymer-coated surfaces is crucial for optimizing applications such as self-cleaning materials or microfluidic devices. While the static and…
Chemical Physics of Controlled Wettability and Super Surfaces
Carolina Brito, Hans-Jürgen Butt, Alberto Giacomello
Wetting phenomena are widespread in both natural and technological contexts. Despite the well-established nature of this scientific field and our extensive knowledge of its underly…
Morphology and dynamics of dense nanometric precursor lms of polymer melts
Claire Schune, Marc Yonger, Mohamed Hanafi +6
Nanometer-thick supported lms of polymer melts spontaneously form and spread around sessile droplets that are deposited on oxidized silicon wafers. At steady state, the lms become…
Glass transition temperature of thin polymer films
Hsiao-Ping Hsu, Kurt Kremer
The glass transition temperature and its connection to statistical properties of confined and free-standing polymer films of varying thickness containing unentangled to highly enta…
Surface charge deposition by moving drops reduces contact angles
Xiaomei Li, Aaron D. Ratschow, Steffen Hardt +1
Slide electrification - the spontaneous charge separation by sliding water drops - can lead to an electrostatic potential of 1 kV and change drop motion substantially. To find out,…
Capillary filling of polymer chains in nanopores
Jianwei Zhang, Jinyu Lei, Wenzhang Tian +3
We performed molecular dynamics simulations with a coarse-grained model to investigate the capillary filling dynamics of polymer chains in nanopores. Short chains fill slower than…
Coherent X-ray Scattering Reveals Nanoscale Fluctuations in Hydrated Proteins
Maddalena Bin, Mario Reiser, Mariia Filianina +15
Hydrated proteins undergo a transition in the deeply supercooled regime, which is attributed to rapid changes in hydration water and protein structural dynamics. Here, we investiga…
Finite-size excess-entropy scaling for simple liquids
Mauricio Sevilla, Atreyee Banerjee, Robinson Cortes-Huerto
We introduce and validate a finite-size two-body excess entropy integral equation. By using analytical arguments and computer simulations of prototypical simple liquids, we show th…
