Overview
Computational Nanoscience. We are interested in modeling nanostructured systems, such as supercapacitors created using ionic liquids as the electrolyte and nanoporous carbons as the electrodes. We work closely with experimentalists who probe the nanoscale structure using neutron and X-ray scattering.
Molecular Rheology of Bulk and Nanoconfined Lubricants. Using several
non-equilibrium molecular dynamics simulation methods, we study the rheology
(particularly viscosity) of typical lubricants used in conventional (e.g.,
automotive) and unconventional (e.g., disk drive lubrication) applications. Our
goal is to develop tools that will enable lubricant designs to be tested
computationally before deciding a lubricant is sufficiently superior to others
that it is worth synthesizing. The effect of nanoscale confinement on
lubricants can be extreme: a molecular fluid that is an effective lubricant in
bulk may become a solid under confinement, depending on degree of confinement
and the strength of the interaction between the solid and the lubricant.
