Journal ArticleDOI
Switchable Static and Dynamic Self-Assembly of Magnetic Droplets on Superhydrophobic Surfaces
TL;DR: A model system based on ferrofluid droplets on superhydrophobic surfaces that self-assemble under a static external magnetic field into simple patterns that can be switched to complicated dynamic dissipative structures by applying a time-varying magnetic field.
Journal ArticleDOI
Multifunctional High‐Performance Biofibers Based on Wet‐Extrusion of Renewable Native Cellulose Nanofibrils
TL;DR: The main interest in NFC has been to generate strong and tough nanopapers, nanocomposites upon adding small contents to polymeric matrices, or robust foams and aerogels, which ranks NFC at the top end of high-performance natural materials.
Journal ArticleDOI
Oleoplaning droplets on lubricated surfaces
Dan Daniel,Jaakko V. I. Timonen,Jaakko V. I. Timonen,Ruoping Li,Seneca J. Velling,Joanna Aizenberg,Joanna Aizenberg +6 more
TL;DR: In this paper, the authors show that for a moving droplet, the film thickness follows the Landau-Levich-Derjaguin law and the droplet is therefore oleoplaning with minimal dissipative force and no contact line pinning.
Journal ArticleDOI
Origins of Extreme Liquid Repellency on Structured, Flat, and Lubricated Hydrophobic Surfaces
Dan Daniel,Jaakko V. I. Timonen,Jaakko V. I. Timonen,Ruoping Li,Seneca J. Velling,Michael J. Kreder,Adam Tetreault,Joanna Aizenberg,Joanna Aizenberg +8 more
TL;DR: It is found that the dissipative force-due to very different physical mechanisms at the contact line-is independent of velocity on superhydrophobic surfaces but depends nonlinearly on velocity for flat and lubricated surfaces.
Journal ArticleDOI
A facile template-free approach to magnetodriven, multifunctional artificial cilia.
Jaakko V. I. Timonen,Christoffer Johans,Kyösti Kontturi,Andreas Walther,Olli Ikkala,Robin H. A. Ras +5 more
TL;DR: Flexible and magnetic artificial cilia were grown on various substrates by a facile bottom-up approach based on template-free magnetic assembly and suggest applications as an externally controllable surface.
