Description

The Thermodynamics Research Center group conducts interdisciplinary research at the cutting edge of the intersection of nanomechanics, mesoscale physics, and chemistry. Our specific interests are in the charge/mass transport and interfacial phenomena in condensed-matter (liquid- and solid-state) systems at the nanoscale. Our work is performed in collaboration with experimental scientists and the potential applications range from water desalination and DNA sequencing to achieving ultralow friction.

We utilize a set of methods, including coordination chemistry, multi-barrier transition state theory, large-scale molecular dynamics simulations, and density functional theory calculations. Outstanding candidates are encouraged to submit research proposals on the following topics:

  • Aqueous ion transport across subnanoscale pores in two-dimensional materials (boron nitride, transition metal dichalcogenides, graphene, MXenes) for applications in molecular separations and water desalination.
  • Physics of solid-state and solid-state-biomolecular hybrid devices for DNA/protein sequencing.
  • Structural and thermodynamic properties of static and kinetic friction in two-dimensional and lamellar materials.
  • Ionic liquids in nanoscale confinement for applications in supercapacitor energy storage.

We also welcome proposals on topics not specifically listed above.
