Particle-Environment Interactions



Our team focuses its research on three research fields:

  1. Microplastic and tire and road wear particles
    What is the fate of tire wear particles in aquatic environments?
    How can we predict microplastic emissions from urban areas?

  2. Fate and transport of nanoparticles in the enviroment
    How are natural colloids transported and transformed in aquatic environments under dynamic hydrochemical conditions e.g. aggregation, dissolution and mobilization?
    Particulate emissions from road transport
  3. 3. Nanosafety research
    Development of characterization techniques for nanomaterials
    How does the surface coating of a nanomaterial alter under environmental conditions and what is its effect on particle fate e.g. particle-biota interactions?
    How can we quantify traffic related nanomaterial emissions?
    Spatial distribution of chemicals in aquatic organisms

Our laboratory is equipped with high-end instrumentation and numerous experimental possibilities for particle characterization and quantification. We analyze particle size, particle composition and particle surface properties of inorganic and organic particles. In particular our lab is equipped with     

  • Elemental analysis: ICP-MS (Thermo ICapQ, Element), ICP-OES (Spectro ARCOS)
  • Particle size fractionation: asymmetric flow-FFF (Wyatt Eclipse 3), rotating coiled column (RCC),
  • Particle sizing: dynamic light scattering (Nanostar, Wyatt), laser obscuration time analysis (Eyetech).
  • Elemental analysis in solid samples: laser ablation ICP-MS (G2 Analyte, Teledyne Cetac coupled to SpectroMS, Spectro at the ProVis facility
  • Polymer analysis: µFTIR imaging (Cary 620 FTIR Microscope, Cary 670 spectrometer, Agilent)

Further we have access to the instrumentation of the ProVis facility and Department of Analytical Chemistry including Raman spectroscopy and MALDI-MS

The work on these research fields is done in collaboration with internal and external partners.
