Atomic force microscopy reveals liquids adjust viscosity when confined, shaken
(Georgia Institute of Technology Research News) New research shows that when water is confined to a small space, it behaves like a gel. Then, when shaken, it becomes fluidic and exhibits the same structural and mechanical properties as water in a bottle. The study -- the first to use an atomic force microscope to measure the viscosity of confined fluids -- revealed that these liquids can respond and modify their viscosity based on environmental changes.
