NIST Diffusion Workshop Group


The next workshop is planned for June 14-16, 2022.  The workshop will honor John Agren and pay tribute to John Morral.   POSTPONE until 2023.

  • To improve communication between experts in multicomponent diffusion measurement, analysis and simulation.
  • To establish the most efficient method for extracting diffusion data (diffusion coefficients, fluxes, marker location) from multicomponent diffusion couple experiments.
  • To provide a forum to solve common diffusion software execution problems.
  • To agree on a common diffusion mobility database assessment procedure.
  • To establish a general approach to data handling and diffusion modeling in ordered phases.
  • To develop standard problems and web site for inter-laboratory comparison of diffusion simulation methods and data extraction techniques.
