Swelling and evaporation determine surface morphology of grafted hydrogel thin films
Caroline Kopecz-Muller, Clémence Gaunand, Yvette Tran +5
We experimentally study the formation of surface patterns in grafted hydrogel films of nanometer-to-micrometer thicknesses during imbibition-driven swelling followed by evaporation…
Delamination from an adhesive sphere: Curvature-induced dewetting versus buckling
Finn Box, Lucie Domino, Tiago Outerelo Corvo +4
Everyday experience confirms the tendency of adhesive films to detach from spheroidal regions of rigid substrates -- what is a petty frustration when placing a sticky bandage onto…
Cloaking by coating: How effectively does a thin, stiff coating hide a soft substrate?
F. Box, C. Jacquemot, M. Adda-Bedia +1
From human tissue to fruits, many soft materials are coated by a thin layer of a stiffer material. While the primary role of such a coating is often to protect the softer material,…
Limitations of curvature--induced rigidity: How a curved strip buckles under gravity
Matteo Taffetani, Finn Box, Arthur Neveu +1
The preference of thin flat sheets to bend rather than stretch, combined with results from Geometry, mean that changes in a thin sheet's Gaussian curvature are prohibitively expens…
Guided droplet transport on synthetic slippery surfaces inspired by a pitcher plant
Finn Box, Chris Thorogood, Jian Hui Guan
We show how anisotropic, grooved features facilitate the trapping and directed transport of droplets on lubricated, liquid-shedding surfaces. Capillary action pins droplets to topo…
Dynamic buckling of elastic rings in a soap film
Finn Box, Ousmane Kodio, Doireann O'Kiely +3
Dynamic buckling may occur when a load is rapidly applied to, or removed from, an elastic object at rest. In contrast to its static counterpart, dynamic buckling offers a wide rang…
Impact on floating thin elastic sheets: A mathematical model
Doireann O'Kiely, Finn Box, Ousmane Kodio +2
We investigate impact of a sphere onto a floating elastic sheet and the resulting formation and evolution of wrinkles in the sheet. Following impact, we observe a radially propagat…
Dynamics of wrinkling in ultrathin elastic sheets
Finn Box, Doireann O'Kiely, Ousmane Kodio +3
The wrinkling of thin elastic objects provides a means of generating regular patterning at small scales in applications ranging from photovoltaics to microfluidic devices. Static w…
Wettability-independent droplet transport by \emph{Bendotaxis}
Alexander T. Bradley, Finn Box, Ian J. Hewitt +1
We demonstrate \textit{bendotaxis}, a novel mechanism for droplet self-transport at small scales. A combination of bending and capillarity in a thin channel causes a pressure gradi…
Indentation of a floating elastic sheet: Geometry versus applied tension
Finn Box, Dominic Vella, Robert Style +1
The localized loading of an elastic sheet floating on a liquid bath occurs at scales from a frog sitting on a lily pad to a volcano supported by the Earth's tectonic plates. The lo…
