This course provides a comprehensive overview on the methods used for the characterization of particles, particle systems and microstructures of heterogeneous materials, including nanoparticles, nanocrystalline and nanoporous materials. In the first part parameters for the description of the size, shape and arrangement of particles, grains and pores in microstructures are defined and the statistics of small particles, grains and pores is explained, including quantiles, mean values, moments and moment ratios. In the second part the different methods for the characterization of particles, grains and pores are treated in some detail, from sedimentation methods, laser diffraction, dynamic light scattering, image analysis, X-ray diffraction, adsorption methods and mercury porosimetry to less popular methods for the characterization of particles and microstructures. A special focus of this course is the evaluation of planar sections of the microstructure using stereological relations and the use of integral transformations for the correction of the random section problem. In two lectures also sintering and disperse systems are briefly treated, including suspensions and nanofluids and methods for characterizing their electrokinetic behavior. The course is suitable for students of all fields of chemistry and materials science and engineering. It can be particularly recommended for everyone interested in characterizing systems of small particles or microstructures of heterogeneous materials.
