Moment Dynamics of Zirconia Particle Formation for Optimizing Particle Size Distribution

open access: yesNanomaterials, 2019
We study the particle formation process of Zirconia ( ZrO 2 )-based material. With a model-based description of the particle formation process we aim for identifying the main growth mechanisms for different process parameters.

Influence of Mie scattering on nanoparticles with different particle sizes and shapes: photometry and analytical ultracentrifugation with absorption optics [PDF]

open access: yesJournal of the Serbian Chemical Society, 2005
Nanoparticles are used in large quantities for very different applications. A precise determination of the diameter and the particle size distribution which is responsible for the application properties is therefore essential.

Varying particle size selectivity of soil erosion along a cultivated catena

open access: yesOpen Geosciences, 2023
Sheet erosion is a complex multi-factor-dependent process with high spatial heterogeneity on hillslopes. Although the individual factors have been well studied, their aggregated effect on size-selective erosional processes is highly uncertain. Therefore,
