Microcosm of materials: small cause - big effect
Wednesday: 2:00 - 3:30 p.m.
Place: Wilhelm-Klemm-Str. 10 - IG1 room: 619/620
The history of mankind and the overcoming of current and future challenges is closely linked to the continuous development of new and improved materials. In the Stone Age (until around 2200 BC), Bronze Age (around 2200 to 800 BC) and Iron Age (800 BC to 0 BC), tools were mainly made of stone, bronze (copper-tin alloy) or iron. Iron swords with superior properties to other swords are known from history and their glorification is often emphasized in fantasy films. However, the development of our society today is also characterized by materials with special properties. In addition to the properties of materials, the processes involved in their production and the repeated use of raw materials are of eminent importance. In addition to the special properties of steel, a mixture of iron and carbon, which make it possible to build large structures several hundred meters high, another example is silicon, which, as a raw material for the production of electronic components, has played a decisive role in the digital revolution of our society. But what exactly determines the special macroscopic properties of a material, such as its hardness or electrical conductivity? How do manufacturing processes influence the properties and which material-physical processes and phenomena are important for manufacturing and recycling? Many of these aspects are hidden in the microscopic structure of the material and cannot be easily observed from the outside. In this seminar we will use the example of steel, a modern material of great importance for the global economy and the ecological balance of industrialized nations, to illuminate and discuss the microscopic causes of the special properties of metallic materials and methods for their analysis on the basis of selected publications, in order to be able to derive fundamental principles for the development of new materials with desired properties from an understanding of the microcosm of this class of materials.
Laboratory course in material physics
block internship: 04.2.2025 - 28.03.2025
Most important part of the teaching program in materials physics. Ten experiments are offered that exemplify the subjects of the introductory lectures "Materials Physics I + II" and demonstrate specific methods in material science.
Shortterm Research Project in Labs of Prof. Salinga
Tuesday, 08.10.2024 14:00
Place: Seminarroom 619, IG 1, Wilhelm-Klemm-Str. 10
A deeper understanding of a subject can be achieved by working on a project as it is typical for both academic and industrial research. Hence, in the Physical Specializations Materials Physics, Photonics and Magnonics, and Nonlinear Physics, it is possible to choose such a learning format. In a mini research project a student works on a small research task. In contrast to a prepared lab course, here a student contributes to the solution of a real problem addressed by the research group of Prof. Salinga. Students are immersed in a research team collaborating closely with more experienced scientists. This work will be concluded by a seminar talk about this project given by the student. Topic, time and duration can be very flexible (5 credit points / 150 hours) and will be agreed upon together with Prof. Salinga.
Practical tutorial
Monday 9:00- 17:00
Room 619/620 IG 1
Experiments supervised by the Salinga working group at the Institute of Materials Physics:
MP1: solar cells
MP6: phase change materials
