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.…
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…
Interfacial strength dominates fold formation in microscale, soft static friction
Justin D. Glover, Xingwei Yang, Rong Long +1
Utilizing colloidal probe, lateral force microscopy and simultaneous confocal microscopy, combined with finite element analysis, we investigate the mechanism of static friction for…
Shaping Nanoscale Ribbons into Micro-Helices of Controllable Radius and Pitch
Lucas Prévost, Dylan M. Barber, Marine Daïeff +5
We report fabrication of highly flexible micron-sized helices from nanometer-thick ribbons. Building upon the helical coiling of such ultra-thin ribbons mediated by surface tension…
Capillary-driven indentation of a microparticle into a soft, oil-coated substrate
Justin D. Glover, Jonathan T. Pham
Small scale contact between a soft, liquid-coated layer and a stiff surface is common in many situations, from synovial fluid on articular cartilage to adhesives in humid environme…
