In this project, after the lecturer's introductory seminar at the beginning of the semester, each student receives a defined technical task in the field of measurement technology of nanodisperse systems. This task includes a measurement technique for a nanodisperse system and is selected from a list or suggested by the student himself. The task is carried out individually under the professional guidance of the lecturer and is to be carried out like a project, including specification of the metrological properties to be determined, literature research, market research, explanation of the measuring principle, if necessary measurements at the measuring device manufacturer, reporting and presentation of the results. It should be reported at regular intervals on the basis of a short presentation to the lecturer about the level of knowledge. The final report must be submitted to the lecturer before the seminar. In the joint final seminar, the most important findings are presented in a lecture. The individual performance of the participants is graded.
In his final report, the student should report on:
- possible continuous and disperse phases (e.g. gas / liquid)
- Which size-related properties can be recorded (which equivalent diameter, shape, concentration range, etc.)
- the method-specific properties of the selected measuring technology (such as measuring range, resolution, sensitivity, required sample preparation, in / at / online capability), measuring time, development status, etc.)
- A scientifically sound explanation of the measuring principles with details of the essential innovations, both from the accessible literature and already implemented in commercially available devices. If possible, information should also be collected through personal conversations with developers and / or users
- Specific metrological properties of the measuring devices available on the market
The students learn systematically to work out a task / a question from the field of nanotechnology, to work out the goals and to work on them under professional supervision. In addition to the technical training in the field of nano measurement technology, students are taught very important 'soft skills', such as Technical research, presentation, literature research, etc., which are required for later employment or for further qualification to a scientific master's degree.
After the event has been carried out actively, the students are sensitized to the metrological requirements for metrology for nano-objects. They are able to independently acquire and acquire the basic principles of nano measurement technology from scientific literature and explain them in a manner that is understandable for their colleagues. They can independently elucidate and classify the principal possibilities and limits of nano measurement technology, as well as the specific possibilities of an existing measuring device and their technical boundary conditions.
