The dynamics and deformations of immersed flexible fibers are at the heart of important
industrial and biological processes, induce peculiar mechanical and transport properties in …

We report on a microscopic poly (N-isopropylacrylamide) hydrogel ribbon, coated by a thin
gold layer, that shows helical coiling. Confined swelling and shrinkage of the hydrogel …

Ciliary oscillations driven by molecular motors cause fluid motion at micron scale. Stable
oscillations require a substantial source of dissipation to balance the energy input of motors …

This paper reports an experimental and theoretical investigation of the hydrodynamic
interaction of a deformable structure with gravity waves. High-speed imaging and particle …

The relaxation dynamics of a bent rod immersed in a fluid is studied experimentally for
various rod materials and sizes and fluid viscosities. One extremity of the rod is clamped …

Coiling of rope, fed from a height onto a rotating plane, progresses through a sequence of
shapes, a hypotrochoid to an epitrochoid to a circle as the frequency of the plane increases …

Active filaments are out-of-equilibrium systems that undergo spontaneous oscillations by
converting chemical or other forms of energy into mechanical motion [1]. Compared to their …
