529-0941-00LIntroduction to Macromolecular ChemistryW4 credits3GA. D. Schlüter
AbstractBasic definitions, types of polyreactions, constitution of homo- and copolymers, networks, configurative and conformative aspects, contour length, coil formation, mobility, glass temperature, rubber elasticity, molecular weight distribution, energetics of and examples for polyreactions.
ObjectiveUnderstanding the significance of molecular size, constitution, configuration and conformation of synthetic and natural macromolecules for their specific physical and chemical properties.
ContentThis introductory course on macromolecular chemistry discusses definitions, introduces types of polyreactions, and compares chain and step-growth polymerizations. It also treats the constitution of polymers, homo- and copolymers, networks, configuration and conformation of polymers. Topics of interest are contour length, coil formation, the mobility in polymers, glass temperature, rubber elasticity, molecular weight distribution, energetics of polyreactions, and examples for polyreactions (polyadditions, polycondensations, polymerizations). Selected polymerization mechanisms and procedures are discussed whenever appropriate throughout the course. Some methods of molecular weight determination are introduced.
Lecture notesCourse materials (consisting of personal notes and distributed paper copies) are sufficient for exam preparation.
Prerequisites / NoticeThe course will be taught in English. Complicated expressions will also be given in German. Questions are welcome in English or German. The written examination will be in English, answers in German are acceptable. A basic chemistry knowledge is required.

PhD students who need recognized credit points are required to pass the written exam.

AbstractThe lecture reviews the basics of microscopy by discussing wave propagation, diffraction phenomena and aberrations. It gives the basics of light microscopy, introducing fluorescence, wide-field, confocal and multiphoton imaging. It further covers 3D electron microscopy and 3D X-ray tomographic micro and nanoimaging.
ObjectiveSolid introduction to the basics of microscopy, either with visible light, electrons or X-rays.
ContentIt would be impossible to imagine any scientific activities without the help of microscopy. Nowadays, scientists can count on very powerful instruments that allow investigating sample down to the atomic level.
The lecture includes a general introduction to the principles of microscopy, from wave physics to image formation. It provides the physical and engineering basics to understand visible light, electron and X-ray microscopy.
During selected exercises in the lab, several sophisticated instrument will be explained and their capabilities demonstrated.

AbstractThe lecture describes various nanomaterials (semiconductor, metal, dielectric, carbon-based...) for photonic applications (optoelectronics, plasmonics, photonic crystal...). It starts with nanophotonic concepts of light-matter interactions, then the fabrication methods, the optical characterization techniques, the description of the properties and the state-of-the-art applications.
ObjectiveThe students will acquire theoretical and experimental knowledge in the different types of nanomaterials (semiconductors, metals, dielectric, carbon-based, ...) and their uses as building blocks for advanced applications in photonics (optoelectronics, plasmonics, photonic crystal, ...). Together with the exercises, the students will learn (1) to read, summarize and discuss scientific articles related to the lecture, (2) to estimate order of magnitudes with calculations using the theory seen during the lecture, (3) to prepare a short oral presentation about one topic related to the lecture, and (4) to imagine a useful photonic device.
