Construction Work

Due to construction work, laboratory 3339 will be closed from 25. November until probably 05. December and the microscopy laboratory from 28. November until probably 07. December.

Server replacement and restructuring of the accounts

The servers of the Nanozentrum need to be replaced because of their age. This triggered a few changes:
1.) Currently all of the data is stored locally on two mirrored servers and is backed up into the ZID system every night. Since I (Stephan Puchegger) am the sole person responsible for the servers, the failure of e.g. hard-disks led to various problems in the past. E.g. My server informed my once via email that two hard-disks had failed when I was away from the university doing my mandatory military service with no option to exchange the two disks on short notice. This was an almost catastrophe, I do not want to repeat.

I will thus in the future not store the data locally, but on a ZID share. This implies a better data integrity, but also a higher latency when accessing the data (reading/writing). I pray for you forgiveness.

2.) I am usually not informed which professors come or go. Because of that, the new account system will be based on institutes (chemistry) and research groups (physics). This means that there will not be an account for people associated with prof. X, but there will be an account for everyone associated with research group/institute Y, which includes prof. X. These accounts have already been created. Please ask either me, Martina Hofmann or Daniel Gitschthaler about the correct username.

3.) Because the servers are being replaced, the data can only be accessed via the IP address in the future. The procedure itself stays the same. Old data will stay available and is mirrored from the old servers to the new servers every night.

4.) Every share now contains folders with the names of subgroups belonging to an institute/research group on the top-level. These folders should contain folders with the following name-scheme for all the users: "Lastname Givenname". How you store your data within these folders is up to you.

5.) There are now u:Cloud calendars for each instrument.

6.) The old and new servers will exists side-by-side for a while, but more and more equipment will move to the new servers. Currently only the computers of the SENtech SENpro, the Anton-Paar micro-hardness-tester and the old Axioplan have been moved to the new servers.

7.) Most of the measurment systems will be moved to a non-routeable network without internet access. The reason is that I have only limited control over the subnet of the former institute of materials physics and some of the computers still run Windows 7 or XP and cannot be upgraded to a more up-to-date operating system. This also means pen-drives are a no-go and I barricaded all the USB ports. (A positive side-effect are less Windows "feature" updates.)

If you have any further questions please contact Stephan Puchegger.

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

Earth as seen from Voyager 1, February 14th, 1990

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.
