2021 CCMX Advanced Course: Powder Characterisation and Dispersion – from nanometers to millimeters and from theory to practice

Wednesday 30 June to Friday 2 July, 2021 – Materials Institute, EPFL & CSEM Neuchâtel

“It was great to have theoretical and experimental parts in the same course.”


  • Introduction to some basic methods used for powder characterisation, particle size measurement and a brief introduction to powder dispersion and suspension characterisation.
  • Brief discussion of the fundamental theories behind the methods and their limitations.
  • Measurement of real samples and correct interpretation of the results collected.
  • Presentation of in-house protocols for reproducible and reliable measurements (towards metrology).
  • Examples of “real” powders in applications and the influence of their intrinsic characteristics.
  • Presentation of in-house software and models for interparticle interactions and yield stress prediction.

This course may be validated for 1 ECTS credit in the doctoral programs of EPFL and ETHZ after acceptance by the corresponding institution. The credit will be attributed to students who pass the examination held on 2 July 2021 after the course.


Prof. Paul Bowen (EPFL), Dr. Olha Sereda (CSEM)
