According to very recent Corona regulations given by the Rector and Deans of our University/Faculties, we have to start our lab course "Materials Science" already in June 2020 and finish it by end of July 2020 at the latest.

Therefore the organisation meeting have to take place already in the last week of May; it will be on Monday May 25, 2020, 11:00 h and held as a video-conference online, what means that you have to share the meeting from your home (office) using your PC or laptop equipped with microphone and camera. You can join the meeting by clicking the URL for a common JITSI video-conference

jm01.univie.ac.at/JitsiMatPrakt
For its opening you need to use your uni-account, which is - if you are a student - identical with your unet-e-mail.

We are sorry that due to the recent regulations mentioned above, we can accept only 4 (four) students to be inscribed in that lab course during the summer term 2020. Perhaps somebody of you steps back voluntarily already now; the lab course is held each semester and so also in the winter term 2020-21 beginning in October 2020. As an exception, we can already register you already now for the winter term 2020-21 and guarantee a participation there. If there are no volunteers for stepping back, we have then to negotiate the 4 students for the actual lab course SS 2020 during the organisation meeting.


Information

Aims, contents and method of the course

This course is composed of two parts: (1) the part in Chemistry: 270305-1 SE+UE Moderne Methoden zur Charakterisierung von Materialien and (2) the part in Physics 260060 SE+UE. Participants have to enlist in both parts (two different faculties).
The course intends to provide a general introduction into the tasks of crystal structure determination (a) from X-ray powder data as well as (b) from X-ray single crystal data.
These techniques will be demonstrated on selected examples.
The course is highly recommended as a specific preparation for master work and/or a doctoral thesis in materials chemistry.

Contents (part in Physical Chemistry): Introduction to production and properties of X-rays. Fundamental principles of X-ray diffraction. Indexation of X-ray powder patterns (Example 1). Techniques and interpretation of powder diffraction data; qualitative and quantitative analysis of crystalline powders (Rietveld analysis) as well as ab-initio determination of an unknown crystal structure from X-ray powder data (Example 2). Methods of solving the phase problem. Direct methods for structure determination and refinement from X-ray single crystal data (Example 3). Introduction to EPMA (Electron Microprobe Analysis; Example 4).
The introductory course is accompanied by tutored exercises on these major tasks (1-4) and by concomitant training in various computer programs (Fullprof, Oscail, Atoms).

Assessment and permitted materials

The judging of students is derived from the activity in seminars, the engagement during the experiments, and from the result of final questioning.

Minimum requirements and assessment criteria

Correct handling of modern research facilities, good physico/chemical understanding, suitable documentation of experiments, and the specific preparation for master work and/or a doctoral thesis in materials chemistry.

Examination topics

The lab course uses modern audio-visual tools and state-of-the-art research instruments.
