Researchers used fluorescence microscopy and particle tracking velocimetry to image the motion of concentrated emulsions and microgel suspensions near solid surfaces. Two non-thixotropic yield stress materials were used as models to study how soft particle glasses yield and flow at solid surfaces. The flow of the soft particle glasses was shown to be influenced over macroscopic distances by the nature of the surface (rough, smooth, etc).
