OLAT
In the Modul "Biogeochemical Interfaces" (ACP2), the students will learn about:
- The central role of interfaces for environmental processes such as sorption and transport of environmental contaminants, bioavailability and toxicity
- The intense interactions between physics, chemistry and biology
- The analysis of interfacial processes and are competent for independent interdisciplinary process-oriented experiments
In the lecture "Biogeochemical Interfaces", the following topics will be treated:
- Fundamental basics in colloid and surface chemistry
- Biogeochemical interfaces: organic soil, mineral and organic surfaces in soil and sediment, biofilms, viruses, microorganisms, natural and engineered colloids and nanoparticles
- Physicochemical environmental processes and interfaces: sorption, catalysis, pollutant mobilization, colloid-facilitated pollutant transport, wetting
- Interactions between biology and chemistry: physicochemical influence of sorption and mobilization of environmental chemicals by bacterial biofilms and root-exudates, bacteria transport in the soil and the water, interactions between colloids and biofilms
- Recent techniques to study Biogeochemical Interfaces, e.g. Dynamic Light Scattering (DLS), Rheology, 1H Nuclear Magnetic Resonance Relaxometry (1H-NMR), Envirnonmental Scanning Electron Microscopy (ESEM), Atomic Force Microscopy (AFM), Dynamic Contact Angle Meter and Tensiometer (DCAT)...
In the laboratory, the students will gain experiences in recent techniques used to study BGIs, e.g.:
- Contact Angle
- Electron Microscopy (ESEM)
- NMR Relaxometry
- ...
