Fully nonlinear dynamics of stochastic thin-film dewetting

Authors: S. Nesic, R. Cuerno, E. Moro, and L. Kondic Journal: Physical Review E 92, 061002(R) LINK | PDF Abstract: The spontaneous formation of droplets via dewetting of a thin fluid film from a solid substrate allows materials nanostructuring. Often, it is crucial to be able to control the evolution, and to produce patterns characterized by regularly spaced droplets. While thermal fluctuations are expected to play a role in the dewetting process, their relevance has remained poorly understood, particularly during the nonlinear stages of evolution that involve droplet formation. ...

Searching for someone

From the “Small World Experiment” to the “Red Balloon Challenge,” and beyond We live in a small world, right? But the cost and fragility of navigating it could harm any potential strategy to leverage the power of social networks. Read this fascinating story of the research, experiments, and failures in the quest for using social networks to search information/people: [Excerpt of the article] Our ability to search social networks for people and information is fundamental to our success. ...
