A recent publication by the Schwartz Group titled, "Intermittent Molecular Hopping at the Solid-Liquid Interface" was featured in the February Soft Matter World newsletter.
In the paper, ChBE Chair Dan Schwartz and researchers Michael Skaug and Joshua Mabry describe using single-molecule tracking to characterize how molecules move at the interface between a solid and liquid. Though most theory assumes molecules moved by a continuous 2D mechanism, this new work shows that a diverse set of molecules actually move by an intermittent, 3D hopping mechanism. This means that molecules can explore a surface much more efficiently than previously thought.
