Solidification and superlubricity with molecular alkane films
Alexander M. Smith, James E. Hallett, Susan Perkin
Hydrocarbon films confined between smooth mica surfaces have long provided an experimental playground for model studies of structure and dynamics of confined liquids. However funda…
Interfacial structure and boundary lubrication of a dicationic ionic liquid
Carla S. Perez-Martinez, Susan Perkin
We report measurements of the normal surface forces and friction forces between two mica surfaces separated by a nano-film of dicationic ionic liquid using a Surface Force Balance.…
Surface forces generated by the action of electric fields across liquid films
Carla Perez-Martinez, Susan Perkin
We explore the force generation and surface interactions arising when electric fields are applied across fluid films. Using a surface force balance (SFB) we measure directly the fo…
