Our paper on the developpement of an instability-assisted microfabrication technique base on the liquid rope coiling instability was accepted for publication in Advanced Materials.

Back cover of june 24th 2015 issue of Advanced Materials.

In the figure above, featured on the back cover of Advanced Materials, a 30 μm diameter thread of poly(lactic acid) (PLA) dissolved in dichloromethane is deposited on top of the eye of a sewing needle. The deposition robot traces a straight line; the helical shape of the thread is due to the liquid rope coiling instability. This instability is used to fabricate microstructured fibers with tailored mechanical.
