19-21 October 2020 – EPFL, Lausanne
- Introduction to the basics behind precipitation of inorganic powders in theory and in practice.
- Discussion of the fundamental concepts of supersaturation, nucleation, growth and aggregation.
- Brief introduction to some basic methods used for powder characterization.
- Demonstration of real sample characterization and correct interpretation of the results collected.
- Presentation of precipitation reactors from batch to continuous and in situ monitoring.
- Presentation of “sol-gel” routes in both aqueous and non-aqueous environments.
- Thermodynamic and kinetic modelling towards understanding growth mechanisms.
This course may be validated for 1 ECTS credit in the doctoral programs of EPFL and ETH Zurich after acceptance by the corresponding institution. The credit will be attributed to students who pass the examination held on 26 March 2020 after the course.
Materials Institute, EPFL – Room MXC315
- Precipitation basics – supersaturation, nucleation, growth and aggregation
- Powder characterization – particle size, surface area, morphology (microscopy), X-ray powder diffraction, zeta potential and thermogravimetric analysis.
- Precipitation in practice – reactor engineering – from batch to continuous reactors
- “Sol-gel” routes in both aqueous and non-aqueous environments and polyol routes
- Modelling – solution thermodynamics, kinetics (population balance), aggregation, self-assembly
- Case Studies – superparamagnetic iron oxides, towards Good Manufacturing Practices (GMP) for biomedical applications
Please note that while the theory presented in this course applies to all types of materials, the practical examples concentrate on inorganic materials. Also due to limited time only a brief overview of the theory can be given although key references for more advanced analysis are provided throughout.
Prof. Paul Bowen (EPFL), Prof. Markus Niederberger (ETHZ), Dr. Andrea Testino (PSI)
