529-0941-00L	Introduction to Macromolecular Chemistry	W	4 credits	3G	D. Opris
Abstract	Basic 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.
Learning objective	Understanding the significance of molecular size, constitution, configuration and conformation of synthetic and natural macromolecules for their specific physical and chemical properties.
Content	This 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 notes	Course materials (consisting of personal notes and distributed paper copies) are sufficient for exam preparation.
Prerequisites / Notice	The 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.

Abstract	The lecture describes various nanomaterials (semiconductor, metal, dielectric, carbon-based...) for photonic applications (optoelectronics, plasmonics, ordered and disordered structures...). It starts with 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.

Abstract	The 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.
Learning objective	Solid introduction to the basics of microscopy, either with visible light, electrons or X-rays.
Content	It 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.
