Title: | A direct observation of nanometer-size void dynamics in an ultra-thin water film | Authors: | Mirsaidov, Utkur Ohl, Claus-Dieter Matsudaira, Paul |
Issue Date: | 2012 | Source: | Mirsaidov, U., Ohl, C.-D., & Matsudaira, P. (2012). A direct observation of nanometer-size void dynamics in an ultra-thin water film. Soft Matter, 8(27), 7108-7111. | Series/Report no.: | Soft matter | Abstract: | Here we report the direct dynamic observation of electron beam induced nucleation of nanometer-diameter voids in a thin water film (<12 nm) on a hydrophilic substrate using an in situ TEM platform tailored towards imaging of liquids. The growth dynamics of these nano-voids in a thin water film reveal that there is a critical diameter below which voids are unstable and close up. However, the coalescence of several of such small and unstable voids allows for pathway to form larger and stable voids. A simple model based on the minimization of free energy explains our experimental observations. | URI: | https://hdl.handle.net/10356/96473 http://hdl.handle.net/10220/10376 |
