When a very flexible wire is dipped into a soapy solution, it collapses onto itself. We consider the regions of high curvature where the wire folds back onto itself, enclosing a capillary film. The shapes of these end loops are measured in experiments using soap films and compared to a known similarity solution. The sizes of these structures provide a simple and reliable way to measure surface tension.

Elasto-capillary collapse of floating structures - Non-linear response of elastic structures under capillary forces
Flexible rings and rectangle structures floating at the surface of water are prone to deflect under the action of surface pressure induced by the addition of surfactant molecules on the bath. WhileExpand
Softly constrained films
The shape of materials is often subject to a number of geometric constraints that limit the size of the system or fix the structure of its boundary. In soft and biological materials, however, theseExpand
Two-Dimensional Capillary Origami with Pinned Contact Line
This article model the static configurations of this capillary origami system in an idealized two-dimensional setting and describes how the plate will fold due to capillary forces. Expand
Theoretical and experimental study of the stability of a soap film spanning a flexible loop
A variational model is used to study the stability of a soap film spanning a flexible loop. The film is modeled as a fluid surface endowed with constant tension and the loop is modeled as an elasticExpand

Recently, Mu et al. [J. Appl. Phys. 115, 044512 (2014)] have developed an analytic approach to describe some special shapes of a single-wall carbon nanotube (SWCNT) under hydrostatic pressure. TheseExpand
Packing transitions in the elastogranular confinement of a slender loop.
New insights are brought into the packing behavior of wires and thin sheets, and will be relevant to modeling plant root morphogenesis, burrowing and locomotive strategies of vertebrates & invertebrates, and developing smart, steerable needles. Expand
Analytical solution of the cantilevered elastica subjected to a normal uniformly distributed follower load
Abstract We report the full analytical solution of the large deformations of a cantilevered elastica loaded by a uniformly distributed follower pressure. We consider an unshearable, inextensible andExpand
Instability Paths in the Kirchhoff–Plateau Problem
This work defines an energy associated with shape deformations of the system and derives general equilibrium and (linear) stability conditions by considering the first and second variations of the energy functional, and finds that the presence of intrinsic curvature is necessary to obtain a first buckling mode which is not purely tangent to the spanning surface.

I am writing with a simple plea to balance the voluminous articles about treatment in your journal with a modicum of information about nature and caring effects to rekindle the perception of physicians as healers, not only treaters, who relish the gifts of nature, and foster the humanistic aspect of medicine that has thrived for millennia.
