- It is commonly assumed that close drops on a solid substrate coalesce. This work demonstrates with rigorous experiments and theory that by playing with the stiffness of the substrate, this behaviour can be altered and an unexpected “capillary repulsion” obtained. Discovery was discussed in more than 30 scientific blogs, including the scientific section of the NY Times: www.nytimes.com/2016/07/14/science/inverted-cheerios-effect-returns-physics-to-the-breakfast-table.html) and highlighted in PNAS commentary (Jagota, PNAS 113.27, 2016). Topic main focus of invited lecture (J. Snoeijer, 68th APS-DFD meeting). Proposed theory underpins a new method to measure the rheological properties of molecularly-thin polymer films (Lhermerout et al. Nature communications 7, 2016).
