The Structure of Agglomerates consisting of Polydisperse Particles

Eggersdorfer M.L., Pratsinis S.E., ETH Zürich, CH

Agglomeration is encountered in many natural or industrial processes, like growth of aerosol particles in the atmosphere, material synthesis by aerosol processes or even colloidal particles. These particles collide by different mechanisms and stick together [...]

Agglomerates and Aggregates: Number and Size of Primary Particles from in-situ Mass-Mobility Measurements

Eggersdorfer M.L., Gröhn A.J., Sorensen C.M., McMurry P.H., Pratsinis S.E., ETH Zürich, CH

Gas-borne nanoparticles generated at high temperatures undergo coagulation forming agglomerates (physically-bound particles) and aggregates (chemically- or sinter-bound particles). The structure of such particles influences their transport, light scattering, effective surface area and density. Real-time characterization [...]
