The (i)RASPA workshop is held at Delft University of Technology (The Netherlands), 2,3,4 September 2024, just before the start of the Thermodynamics2024 conference in Delft (thermodynamics2024.org). The workshop focuses on a practical understanding of molecular simulations of fluids, ionic liquids, and nanoporous materials and application to practical examples. The duration is 3 days, with morning-lectures and afternoon-exercises.

Registration will open in Jan. 2024.

Organizers and lectures:

  • Dr. David Dubbeldam
  • Prof. Randall Q. Snurr
  • Prof. Sofía Calero
  • Prof. Thijs J.H. Vlugt
