Molecular Motion at Soft and Hard Interfaces:
From Phospholipid Bilayers to Polymers and Lubricants

Spatially resolved and time-resolved understanding of complex fluid situations compose a new frontier in physical chemistry. Here we draw attention to the significance of spatially resolving systems whose ensemble average differs fundamentally from the spatially resolved individual elements. We take examples from the field of fluid phospholipid bilayers, to which macromolecules adsorb; the field of polymer physics, when flexible chains adsorb to the solidliquid interface; and from the field of lubrication, when two solids are squeezed close together with confined fluid retained between them.
