327-1202-00L | Solid State Physics and Chemistry of Materials I | W Dr | 5 KP | 4G | N. Spaldin | ||||||||||||||||||||||

Kurzbeschreibung | In this course we study how the properties of solids are determined from the chemistry and arrangement of the constituent atoms, with a focus on materials that are not well described by conventional band theories because their behavior is governed by strong quantum-mechanical interactions. | ||||||||||||||||||||||||||

Lernziel | Electronic properties and band theory description of conventional solids Electron-lattice coupling and its consequences in functional materials Electron-spin/orbit coupling and its consequences in functional materials Structure/property relationships in strongly-correlated materials | ||||||||||||||||||||||||||

Inhalt | In this course we study how the properties of solids are determined from the chemistry and arrangement of the constituent atoms, with a focus on materials that are not well described by conventional band theories because their behavior is governed by strong quantum-mechanical interactions. We begin with a review of the successes of band theory in describing many properties of metals, semiconductors and insulators, and we practise building up band structures from atoms and describing the resulting properties. Then we explore classes of systems in which the coupling between the electrons and the lattice is so strong that it drives structural distortions such as Peierls instabilities, Jahn-Teller distortions, and ferroelectric transitions. Next, we move on to strong couplings between electronic charge and spin- and/or orbital- angular momentum, yielding materials with novel magnetic properties. We end with examples of the complete breakdown of single-particle band theory in so-called strongly correlated materials, which comprise for example heavy-fermion materials, frustrated magnets, materials with unusual metal-insulator transitions and the high-temperature superconductors. | ||||||||||||||||||||||||||

327-1203-00L | Complex Materials I: Synthesis & Assembly | W Dr | 5 KP | 4G | M. Niederberger, A. Lauria | ||||||||||||||||||||||

Kurzbeschreibung | Introduction to materials synthesis concepts based on the assembly of differently shaped objects of varying chemical nature and length scales | ||||||||||||||||||||||||||

Lernziel | The aim is a) to learn how to design and create objects as building blocks with a particular composition, size and shape, b) to understand the chemistry that allows for the creation of such hard and soft objects, and c) to master the concepts to assemble these objects into materials over several length scales. | ||||||||||||||||||||||||||

Inhalt | The course is divided into two parts: I) synthesis of 0-, 1-, 2-, and 3-dimensional building blocks with a length scale from nm to µm, and II) assembly of these building blocks into 1-, 2- and 3-dimensional structures over several length scales up to cm. In part I, various methodologies for the synthesis of the building blocks will be discussed, including Turkevich and Brust-Schiffrin-method for gold nanoparticles, hot-injection for semiconducting quantum dots, aqueous and nonaqueous sol-gel chemistry for metal oxides, or gas-and liquid-phase routes to carbon nanostructures. Part II is focused on self- and directed assembly methods that can be used to create higher order architectures from those building blocks connecting the microscopic with the macroscopic world. Examples include photonic crystals, nanocrystal solids, colloidal molecules, mesocrystals or particle-based foams and aerogels. | ||||||||||||||||||||||||||

327-1204-00L | Materials at Work I | W Dr | 4 KP | 4S | R. Spolenak, E. Dufresne, R. Koopmans | ||||||||||||||||||||||

Kurzbeschreibung | This course attempts to prepare the student for a job as a materials engineer in industry. The gap between fundamental materials science and the materials engineering of products should be bridged. The focus lies on the practical application of fundamental knowledge allowing the students to experience application related materials concepts with a strong emphasis on case-study mediated learning. | ||||||||||||||||||||||||||

Lernziel | Teaching goals: to learn how materials are selected for a specific application to understand how materials around us are produced and manufactured to understand the value chain from raw material to application to be exposed to state of the art technologies for processing, joining and shaping to be exposed to industry related materials issues and the corresponding language (terminology) and skills to create an impression of how a job in industry "works", to improve the perception of the demands of a job in industry | ||||||||||||||||||||||||||

Inhalt | This course is designed as a two semester class and the topics reflect the contents covered in both semesters. Lectures and case studies encompass the following topics: Strategic Materials (where do raw materials come from, who owns them, who owns the IP and can they be substituted) Materials Selection (what is the optimal material (class) for a specific application) Materials systems (subdivisions include all classical materials classes) Processing Joining (assembly) Shaping Materials and process scaling (from nm to m and vice versa, from mg to tons) Sustainable materials manufacturing (cradle to cradle) Recycling (Energy recovery) After a general part of materials selection, critical materials and materials and design four parts consisting of polymers, metals, ceramics and coatings will be addressed. In the fall semester the focus is on the general part, polymers and alloy case studies in metals. The course is accompanied by hands-on analysis projects on everyday materials. | ||||||||||||||||||||||||||

Kurzbeschreibung | In this course the engineering with soft materials is discussed. First, scaling principles to design structural and functional properties are introduced a. Second, the characterisation techniques to interrogate the structure property relations are introduced, which include rheology, advanced optical microscopies, static and dynamic scattering and techniques for liquid interfaces. | ||||||||||||||||||||||||||

Lernziel | The learning goals of the course are to introduce the students to soft matter and its technological applications, to see how the structure property relations depend on fundamental formulation properties and processing steps. Students should also be able to select a measurement technique to evaluate the properties. | ||||||||||||||||||||||||||
