Course Content (Syllabus)
Chapt.1: X-ray diffraction issues Mechansim of material structure differnetiation in x-ray diffraction, diffraction spectrums of basic compounds, crystallite size determination (Scherrer analysis), determination of residual stresses. Chapt. 2: The densities of materials Simple and practical laboratory techniques for the detrmination of densities (i.e. geometrical, fluid immersion, the Archimedes principle, Helium pycnometry) and critical evaluation of the physical meaning of the results received by each method. Definition and determination of densities in powders. Chapt.3: Porosimetry issues The Langmuir isotherm, derivation and application of the BET equation. Derivation of the Kelvin equation and application in Nitrogen porosimetry for pore size distribution determination. Basic principles of Mercury porosimetry. Chapt. 4: Microscopy in solids Optical microscopy. Operation principles, applications and capabilities of scanning electron microscopy (SEM). Operation principles, applications and capabilities of transmission electron microscopy (TEM). Electron microscopy and simultnaeous chemical analysis (EDS). Operation principles, applications and capabilities of molecular force microscopy (AFM, STM, etc.) Chapt.5: Average sizes and size distribution of grains and particles Basic definitions of averae size and size distribution. The laser scattering technique for particle size determination. Practical techniques for the determination of average grain sizes from microscope images. Technigues of digital processing of microscope images for average size determinations (grains, pores, particles etc.) Chapt.6: Thermogravimetric analysis of materials Operation principles of thermogravimetry (TGA), differential thermal analysis (DTA) and differential scanning calorimetry (DSC). Applications of thermal analysis methods (eventually in combination with other techniques) in the determination of combustion kinetics, sorption kinetics or redox kinetics between a material and atmospheric oxygen. Chapt.7: Thermomechanical analysis of solids Operation principles of thermomechanical analysis (TMA) and practical application in the determination of thermal expansion coefficient or sintering kinetics of polycrystalline materials. Chapt.8: Chemical analysis of solids Introduction into the operation principles, the application areas and capabilities of the most common methods of chemical analysis of solids such as atomic adsorption spectroscopy, X-ray fluorescense, ultraviolet spectroscopy and mass spectroscopy. Chapt.9: Gas permeability techniques Introduction to the principles of gas permeability determination of a porous solid and the microstructural information that can be extracted by analysis of the results.

Student Assessment
In this course no classsically defined examinations take place. Instead a homework-project (2 or max. 3 students) final multiple choice test with an approximate duration of half an hour is obligatory taken by the students. The project consists of two stages: In the first stage the team has to determine an industrial production process of a certain product and define the product properties that are essential for its performance as well as the production process unit operations which they are mainly depend on. A short (~5-10 minute) presentation take place in the class. In the second stage the team has to define the diagnosis techniques needed and their exact way of application in the process through which the constant and good quality of the production can be monitored and followed and the ability of detect and explain quality problems. Subsequently and occasionally additional techniques may be defined that will assist the development of new and bettter products (in the same production line). The completed project are presented to the entire class at the end of the semester and the written documents is given to the teacher.
Student Assessment methods
  • Written Exam with Multiple Choice Questions (Formative, Summative)
  • Written Assignment (Summative)
