Nanostructure Determination via Electromagnetic Radiation (B-KUL-G0G99A)

Aims
- You can describe how the interaction of electromagnetic radiation with matter (atoms, molecules, gasses, glasses, solutions, suspensions, liquid crystals, crystals) can be exploited to elucidate its nanostructure (molecular structure, supramolecular organization) and nanostructure based properties (thermo-mechanical, chemical, electrical, magnetic, optical, biological). This knowledge will allow you to understand contemporary, related literature and will enable you to design electromagnetic radiation based experiments in collaboration with experts in the field.
- You understand and can explain the different steps (e.g. the experimental part in a publication) of a crystal structure determination of both small compounds and larger biomolecules.
- You will experience large, international facilities and how big science is used to probe nano-features. You will be able to extract essential information from a talk or a guided tour, given by international top experts.
Previous knowledge
Basic knowledge is required on atomic and molecular structures and orbitals, characteristics of electromagnetic waves, mathematical concepts including the description of waves, integrations, Fourier Transformations. Being familiar with X-ray crystallography is advantageous but not mandatory.

1 ects. Visit of ESRF/ILL (B-KUL-G0T90a)
Content
The student group makes a field trip in which three large international research facilities are visited, i.e. the center for nuclear research CERN in Geneva, the synchrotron facility ESRF in Grenoble and the neutron source ILL in Grenoble. About half a day is spent in each of the facilities. Every visit starts with a general introduction and a presentation of the facility by a local guide. After the general presentation the group is split up and representative setups and beamlines are visited in more detail, guided by local scientists.
Traveling is done with a coach and overnight stays are in local hotels near the highways. According to the faculty rules a financial contribution is requested from the students.
After the visit the students will search for additional material and will write a synthesis report about the visit. The students will also give an oral presentation about these laboratory visits (not for students of G0G99A). A first version of the report and the presentation is reviewed by the professor in charge of that visit (not for students of G0G99A). This feedback is then taken into account by the students in order to finalize their report (not for students of G0G99A).
Course material
Slides of the relevant colleges.

Format: more information
This trip typically takes four days (including two traveling days). Visits to the three institutes typically take half a day each.

Evaluation
Evaluation: Nanostructure Determination via Electromagnetic Radiation (B-KUL-G2G99a)
Explanation
The evaluation of G0G99a and G0T89a will take place at the end of the first semester in the examination period via an oral 'open book' examination with written preparation. If, for reasons of force majeure, the faculty decides that a written exam and an oral defence cannot be combined, the oral defence will be waived and the evaluation will be written.
The examination of G0T90a is a report on the ESRF/ILL visit.
