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…
Phase Separation in Wetting Ridges of Sliding Drops on Soft and Swollen Surfaces
Lukas Hauer, Zhuoyun Cai, Doris Vollmer +1
Drops in contact with swollen, elastomeric substrates can induce a capillary-mediated phase separation in wetting ridges. Using laser scanning confocal microscopy, we visualize pha…
Enhancing condensation on soft substrates through bulk lubricant infusion
Chander Shekhar Sharma, Athanasios Milionis, Abhinav Naga +9
Soft substrates such as polydimethylsiloxane (PDMS) enhance droplet nucleation during the condensation of water vapour, because their deformability inherently reduces the energetic…
Lifting a sessile oil drop from a superamphiphobic surface with an impacting one
Olinka Ramírez-Soto, Vatsal Sanjay, Detlef Lohse +2
Colliding drops are widely encountered in everyday technologies and natural processes, from combustion engines and commodity sprays to raindrops and cloud formation. The outcome of…
Printing surface charge as a new paradigm to program droplet transport
Qiangqiang Sun, Dehui Wang, Jiahui Zhang +8
Directed, long-range and self-propelled transport of droplets on solid surfaces, especially on water repellent surfaces, is crucial for many applications from water harvesting to b…
The Cassie-Wenzel transition of fluids on nanostructured substrates: Macroscopic force balance versus microscopic density-functional theory
Nikita Tretyakov, Periklis Papadopoulos, Doris Vollmer +3
Classical density functional theory is applied to investigate the validity of a phenomenological force-balance description of the stability of the Cassie state of liquids on substr…
The collapse of linear polyelectrolyte chains in a poor solvent: When does a collapsing polyelectrolyte collect its counter ions?
Peter Loh, G. Roshan Deen, Doris Vollmer +4
In order to better understand the collapse of polyions in poor solvent conditions the effective charge and the solvent quality of the hypothetically uncharged polymer backbone need…
Time-resolved X-ray microscopy of nanoparticle aggregates under oscillatory shear
G. K. Auernhammer, K. Fauth, B. Ullrich +3
Of all current detection techniques with nanometer resolution, only X-ray microscopy allows imaging nanoparticles in suspension. Can it also be used to investigate structural dynam…
