COVID-19: Access to the SEM only with an appointment & FFP2 Masks

Because of the current situation with the Corona virus the SEM can only be used by persons that have made an appointment beforehand. Accompanying persons will not be admitted.

Users requiring training must bring their own FFP2/3 mask.


    Construction work in the rooms of the faculty center

    The construction work is now mostly finished. A few things are still missing. The SEM is available again, but the multi-metal-evaporator is not.

    Please check back on a regular basis. We will keep this info-box up-to-date with current information.


    Mission Statement

    The Faculty Center for Nano Structure Research is a service facility and an institutional cooperation between the Faculties of Physics and Chemistry. It is located at the Faculty of Physics and offers scientists and students of the two faculties an easy access to large and expensive instruments, in particular the Zeiss Supra 55 VP scanning electron microscope, a WITec alpha 300A AFM/Raman and the Bruker Nanostar laboratory small-angle X-ray scattering system. Among the other available facilities/services are a Zeiss Axioplan universal light microscope with an attached micro-hardness tester, a self-service grinding, lapping and polishing machine available to all students of the two faculties and an embedding/polishing service for challenging samples. More information can be found in the respective links in the menu on the right side. Please note the terms of use of our laboratories and equipment.


    A Pale Blue Dot

    Consider again that dot. That's here. That's home. That's us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every "superstar," every "supreme leader," every saint and sinner in the history of our species lived there--on a mote of dust suspended in a sunbeam.

    The Earth is a very small stage in a vast cosmic arena. Think of the rivers of blood spilled by all those generals and emperors so that, in glory and triumph, they could become the momentary masters of a fraction of a dot. Think of the endless cruelties visited by the inhabitants of one corner of this pixel on the scarcely distinguishable inhabitants of some other corner, how frequent their misunderstandings, how eager they are to kill one another, how fervent their hatreds.

    Our posturings, our imagined self-importance, the delusion that we have some privileged position in the Universe, are challenged by this point of pale light. Our planet is a lonely speck in the great enveloping cosmic dark. In our obscurity, in all this vastness, there is no hint that help will come from elsewhere to save us from ourselves.

    The Earth is the only world known so far to harbor life. There is nowhere else, at least in the near future, to which our species could migrate. Visit, yes. Settle, not yet. Like it or not, for the moment the Earth is where we make our stand.

    It has been said that astronomy is a humbling and character-building experience. There is perhaps no better demonstration of the folly of human conceits than this distant image of our tiny world. To me, it underscores our responsibility to deal more kindly with one another, and to preserve and cherish the pale blue dot, the only home we've ever known.
