Aims, contents and method of the course

Practical participation and self-dependent experimental work with femto- and nanosecond laser systems on the topic of nanotechnology and physical chemistry predominantly of solid or liquid surfaces.

Possible topics are, depending on current resources:

1. Characterization and modification of spider silk
We will employ µ-Raman spectroscopy to characterize the secondary protein structure of various spider silks in pristine and modified state.
A femtosecond solid-state laser will be used to modify the silk by producing laser induced periodic surface structures (LIPSS) along the silk.
2. Laser machining and characterization of ablated areas on silicon
Optical and scanning electron microscopy, together with µ-Raman spectroscopy will be employed to investigate laser ablated sites under various environments.

Hands-on experimental work with high power ns-laser systems for ceramics- metal- and alloy analysis with laser-induced breakdown spectroscopy for
- chemical stratigraphy: thermal barrier coatings for jet engines (TBCs)
- chemical mapping of additivly manufactured alloys with lateral variable chemical composition (Nabla-materials)
- chemicall analysis of oxide-interfaces on molten alloy samples.
- in-situ monitoring of ablation properties with automated measurement methods: machine vision and optical coherence tomography

Assessment and permitted materials

Immanent evaluation of active participation and written laboratory report and/or seminar presentation of the experimental results.

Minimum requirements and assessment criteria

Practical and theoretical experience in state-of-the-art experimental procedures in recent research.

Examination topics

Hand-on laboratory experience
