Molecularly thin rheological and contact interfaces
A molecularly thin lubricant layer (of the order of 1-2 nanometers thick) has been shown to provide bearing forces at the interface between contacting solid surfaces under light loads and high shear rates. This phenomenon is important, for example, in the head-disk contact in magnetic storage hard …

Relaxations in molecularly thin simple liquid films:linear viscoelasticity and non-linear response to shear
… the linear and nonlinear response of molecularly thin simple liquid films confined between two solid surfaces were studied. The method was to measure the resistance to applied oscillatory shear deformation as a function of frequency and amplitude of deformation, film thickness and …

Transport mechanisms and wetting dynamics in molecularly thin films of long-chain alkanes at solid/vapour interface : relation to the solid-liquid phase transition
… play a very important role our daily life. Molecularly thin films of long-chain alkanes at solid/vapour interfaces (e.g. C30H62 on silicon wafers) are very good model systems for studying the relation between wetting behaviour and (bulk) phase transitions. Immediately above the bulk melting …

Molecular Insights on the Boundary Behavior of Liquids
… thesis concerns the translational diffusion of molecularly thin polymer melt. While simulations have been performed, to my knowledge no direct measurements exist yet of polymer melt diffusion in molecularly-thin films. This is due to the lack of proper experimental tools and the large number of …

Nanoscale interface mechanics with application to magnetic storage
… model is presented for dynamic contact with molecularly thin lubricant layers that exhibit solid-like responses under extremely high shear rates. The limits of continuum theory were investigated based on experimentally measured response of such lubricant layers and accounted for during …

Nanomechanical properties of hydrated organic thin films
Hydrated organic thin films are biological or synthetic molecularly thin coatings which impart a particular functionality to an underlying substrate and which have discrete water molecules associated with them. Such films exist in biology (e.g. cell membrane lipid bilayers) and have a broad array …

Nanocellulose: Preparation, Characterization, Supramolecular Modeling, and its Life Cycle Assessment
… sonication), and this new material was named molecularly thin nanocellulose (MT nanocellulose). The overarching objective of this study was to understand the formation and supramolecular structure of MT nanocellulose and contribute to the knowledge of native cellulose structure. The research …
