Optical microscope images of complex nano-architectures based on silicon particles (magnification 100X, dark field). These structures are obtained via solid-state dewetting of an ultra-thin, flat ...

(Nanowerk News) The phenomenon of ‘dewetting’ — usually considered a nuisance as it causes solids to bead up into islands, much like raindrops on glass — has been harnessed for a useful application.

(Nanowerk News) Excess surface energy from unsatisfied bonds is a significant driver of dimensional changes in thin-film materials, whether formation of holes, contracting edges, or run-away corners.

Video phase field simulation. This material relates to a paper that appeared in the 10 Nov. 2017, issue of Science Advances, published by AAAS. The paper, by M. Naffouti at Université de Toulon in ...
