At BESSY II, we are operating some 50 beamlines, each of which offers the latest methods in spectroscopy and microscopy.
Each beamline has a dedicated beamline scientist, who not only manages all the projects on the beamline and knows its every secret, but also works with local and visiting scientists to get the best results out of the beam and its instruments for every specific research question they have. Without the beamline scientists, much of the science at BESSY II could never happen.
But who are they? What makes a good beamline scientist and where do they come from? In this little series you are going to find out. Today we introduce Dr. Roberto Felix Duarte, who works at the KMC-1 beamline.Read More →

Many colleagues work on site, others continue to work from home. These different working environments will continue to accompany us in the coming weeks. Therefore, we will introduce people telling us what it means to be back in the lab as well as people who continue working from home. Today we ask Rowshanak Irani, postdoctoral researcher at the HZB Solar Fuels Institute based in Wannsee. How did you start the lockdown period? I was lucky, as I had my PhD viva a few weeks before the lockdown. At HZB when you do your PhD in three years you get a contract extension for six months;Read More →

Many colleagues are currently working in their home offices, exchanging information by telephone or video conferencing. Nevertheless, we all miss the opportunity to meet other colleagues in the hallway or in the kitchen. That’s why we are shifting “kitchen conversations” to the digital. Today we introduce Samira Aden. She is an architect and works in the Consulting office for building-integrated Photovoltaics(BAIP) at HZB. How did you establish your home office? Fortunately, I asked my sister shortly before the shutdown if she would like to move in with me for a while. She is doing her doctorate in educational science in Kassel. We have set upRead More →

Can you translate the title of your last talk or paper into plain english? Of course you can. But can you do it using only words out of a list of 1000 most common english words? That becomes tricky!  Give it a try. Be generous and creative. The “Splasho”-Editor will help you: just copy the original text into it and edit until the editor is happy. Example: „Tiny things easily enter into cells. But what do they do there? We have watched them with bright light and found out where they like to be. The cell looks tired after those tiny things have entered.“ ThisRead More →

It is a Russian-German dipole beamline, part of the Russian-German Laboratory at BESSY II. It covers a soft X-ray photon energy range up to 1200 eV. It ends with a fixed experimental station RGL-PES that offers a multi-technique approach for the investigation of the electronic, chemical and structural properties of materials: X-ray photoemission spectroscopy and X-ray absorption in all possible modes (fluorescence yield, total and partial electron yields).Read More →

An Artwork reminds on the scientist who cofounded the Russian German Collaboration at BESSY II It seems, she has just calculated something, a hand lies on the paper, next to the pen. The other one supports the chin, relaxed and curious, she looks at the viewer. The Russian physicist Vera Adamchuk is immortalized in the bronze relief attached to a column in the BESSY II hall. The column stands in front of the dipole beam line of the Russian-German laboratory. Vera Adamchuk is regarded as a pioneer of German-Russian cooperation in the field of synchrotron radiation. She co-founded the Russian-German laboratory at BESSY II inRead More →

The beamline is called PM4. As a dipole beamline, it provides a moderate photon flux over a wide range of photon energies, in our case in the vacuum ultraviolet/soft X-ray regime. It serves the fixed end-station called LowDosePES. As the name suggests, its specialty is photoemission spectroscopy (PES) at low X-ray dose. Read More →

OK, here we are. My name is Vlad. I’m a summer student from Moscow and the author of this note concurrently.  If you are reading this post, I bet 90% you was interested in the title. But I suggest to talk about it a bit later.  Just for the beginning , everything you need to know about solar cells is that they consist of silicon. The second point is that the first one was a lie. In fact, not only silicon is used in solar cells. Since the moment people decided to use solar cells as a real source of energy, scientists have been workingRead More →

I want you to imagine the sun with wrong rays that cause a lot of problems. We cannot enjoy the sunshine. We want to do something to replace the wrong rays with the right ones. In my scientific project, the sun is germanium (Ge) nanoparticles, and the rays are a ligand. The wrong ligand is oleylamine. Oleylamine is an organic molecule containing an amino group and a long hydrocarbon chain. It would be perfect to remove oleylamine from the particles and attach another molecule. Speaking in scientific language, I am trying to do ligand exchange on germanium nanoparticles surface. Why germanium? Firstly, Ge is anRead More →
