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…
Scaling analysis of the screening length in concentrated electrolytes
Alpha A. Lee, Carla Perez-Martinez, Alexander M. Smith +1
The interaction between charged objects in an electrolyte solution is a fundamental question in soft matter physics. It is well-known that the electrostatic contribution to the int…
Switching the structural force in ionic liquid-solvent mixtures by varying composition
Alexander Smith, Alpha Lee, Susan Perkin
The structure and interactions in electrolytes at high concentration have implications from energy storage to biomolecular interactions. However many experimental observations are…
Underscreening in concentrated electrolytes
Alpha A. Lee, Carla Perez-Martinez, Alexander M. Smith +1
Screening of a surface charge by electrolyte and the resulting interaction energy between charged objects is of fundamental importance in scenarios from bio-molecular interactions…
The Electrostatic Screening Length in Concentrated Electrolytes Increases with Concentration
Alexander M. Smith, Alpha A. Lee, Susan Perkin
According to classical electrolyte theories interactions in dilute (low ion density) electrolytes decay exponentially with distance, with the Debye screening length the characteris…
Quantized Friction across Ionic Liquid Thin Films
Alexander M. Smith, Kevin R. J. Lovelock, Nitya Nand Gosvami +2
Ionic liquids, salts in the liquid state under ambient conditions, are of great interest as precision lubricants. Ionic liquids form layered structures at surfaces, yet it is not c…
