Complexity in wetting dynamics

M Roché, L Talini, E Verneuil - Langmuir, 2024 - ACS Publications
The spreading dynamics of a droplet of pure liquid deposited on a rigid, nonsoluble
substrate has been extensively investigated. In a purely hydrodynamic description, the …

Wetting on silicone surfaces

L Hauer, A Naga, RGM Badr, JT Pham, WSY Wong… - Soft Matter, 2024 - pubs.rsc.org
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 …

Phase separation in wetting ridges of sliding drops on soft and swollen surfaces

L Hauer, Z Cai, A Skabeev, D Vollmer, JT Pham - Physical Review Letters, 2023 - APS
Drops in contact with swollen, elastomeric substrates can induce a capillary mediated phase
separation in wetting ridges. Using confocal microscopy, we visualize phase separation of …

Enhanced condensation on soft materials through bulk lubricant infusion

CS Sharma, A Milionis, A Naga… - Advanced Functional …, 2022 - Wiley Online Library
Soft substrates enhance droplet nucleation during water vapor condensation because their
deformability inherently reduces the energetic threshold for heterogeneous nucleation …

Cloaking transition of droplets on lubricated brushes

RGM Badr, L Hauer, D Vollmer… - The Journal of Physical …, 2022 - ACS Publications
We study the equilibrium properties and the wetting behavior of a simple liquid on a polymer
brush, with and without the presence of lubricant by multibody Dissipative Particle Dynamics …

Direct visualization of viscous dissipation and wetting ridge geometry on lubricant-infused surfaces

A Naga, M Rennick, L Hauer, WSY Wong… - Communications …, 2024 - nature.com
Drops are exceptionally mobile on lubricant-infused surfaces, yet they exhibit fundamentally
different dynamics than on traditional superhydrophobic surfaces due to the formation of a …

A reusable electret filter media based on water droplet charging/cleaning

JS Wang, RR Cai, SJ Wu, LZ Zhang - Chemical Engineering Science, 2023 - Elsevier
Electret filter media has been considered as the most effective and economical filtration
material due to its additional electrostatic filtration effect. However, the regeneration and …

Tuning static drop friction

A Laroche, A Naga, C Hinduja, AA Sharifi, A Saal… - Droplet, 2023 - Wiley Online Library
The friction force opposing the onset of motion of a drop on a solid surface is typically
considered to be a material property for a fixed drop volume on a given surface. However …

Coalescence-Induced Self-Propelled Particle Transport with Asymmetry Arrangement

Y Li, H Zhang, J Du, Q Min, X Wu… - ACS Applied Materials & …, 2024 - ACS Publications
