Summary

Four experienced scientists will guide students in nanoparticles (NPs) characterization world with different approaches, from laboratory-based characterization techniques to X-ray scattering and electron microscopy.

Content

The course starts with a general introduction, colloidal stability concepts, and laboratory-based characterization techniques. Then, two sections explore wide and small angle X-ray scattering (WAXS and SAXS) and the information about structure, size, and shape that can be collected in dry NPs and colloids with the support of synchrotron light. Finally, the information accessible via electron microscopy are introduced, such as single particle electron diffraction, tomography, spectroscopy. Each topic consists of about three hours of lecture and about two hours of practical work.

 

Major contents:

 

1. Introduction and laboratory methods for NPs characterization, 5h (Dr. Andrea Testino, MER)

 

2. X-ray diffraction/scattering (WAXS) methods theory and practice, 5h (Dr. Nicola Casati, Group Leader, Beamline Manager)

 

3. X-ray scattering (SAXS) colloidal systems in liquids theory and practice, 5h (Dr. Viviane Lütz Bueno, Instrumental Scientist)

 

4. NPs characterization via electron microscopy (SEM, TEM, ED, EDX, tomography) 5h (Dr. Elisabeth Mueller, Group Leader,Electron Microscopy Manger
