Roland Piquepaille writes "Engineers and physicists working together have discovered that under certain conditions liquid drops and gas bubbles were breaking at two separate points instead of one, leaving an extremely thin thread in between. This could lead to the creation of nanofibers and nanowires and to numerous applications, such as new kinds of composite materials, electronic circuits and pharmaceutical products. Nanotechweb.org reports on this discovery in "Nanowires drop out of fluid research." I'm not totally convinced that this discovery can lead to solid industrial processes, but it sure looks promising. You'll find more details and references in this overview which also includes an image of the break-up of a water drop in oil."
