A Letter by the Helmholtz-Juniors Dear all, October is officially a mental health awareness month. In order to raise awareness among the doctoral researchers, Helmholtz Juniors have prepared a series of informative letters to be sent out each Thursday in the course of October. However, since we – the team of representatives of the doctoral researchers at HZB – believe that this is a topic concerning everyone, we have decided to share some of this information with the whole HZB community. Take a moment, sit back, breathe and relax. We all know that doing a PhD can be really challenging, not only scientifically but alsoRead More →
During my studentship there is one thing I have discovered above all: patience. Patience is the mother of science, as the saying goes. And I have learned it the hard way. My project is a complex one; like most science projects. I’m trying to synthesize and characterize a new material to act as an absorber of light in solar cells. It is called: copper-barium diselenide. More specifically I want this material to be a top-cell absorber in tandem cells. In fact, this synthesis is not easy: little is known about the compound, and barium is very reactive with oxygen, so one must be very carefulRead More →
When one enters the Lab 120 in the Silicon Photovoltaics institute, the first view of it is this: It was kind of a shock to see all these “hands” floating in the air. They reminded me of an astronaut’s space suit. A very interesting tool, which I was very excited to use. One mission: getting the hands into the glove box A glove box is a device permitting you to do experiments in a different atmosphere as outside. Itis very useful if you work with toxic chemicals like here in the Silicon Photovoltaics Institute. As you handle everything with gloves and it is closed soRead More →
Tristan Petit is a “Freigeist” Fellow of the Volkswagen Foundation and heads a group on nanocarbon materials at HZB. In the interview with Sophie Spangenberger, he talks about the gradual normalization after the lockdown. This post is for now the last one about the corona period at HZB. How did you experience the confinement and what was the first thing you did when you arrived at the office? I started the lockdown with a move. So at first I was more stressed by the fear of not being able to move than by the corona virus. We spent the first few weeks confined surrounded byRead More →
Today we present two researchers working on the BAMline and µSpot Beamline at BESSY II. Franziska Emmerling is responsible for the Materials Chemistry Department at BAM and heads a large team for structural analysis. Together with her colleague Ana Guilherme Buzanich, she will report on how they experienced the lockdown and are now carrying out their first experiments again. How did the lockdown start for you? Did you have to interrupt an experiment? Franziska: No, we were lucky, our beam time had just ended and we had tons of data that we had to evaluate anyway. I wrote an email to everyone on March 16thRead More →
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 →
Since some weeks now, many colleagues have come back to the lab, others continue to work from home. These different working environments will continue to accompany us in the coming weeks. This week, Sophie Spangenberger met (online) with Michael Tovar from the X-ray lab at HZB in Wannsee. You are responsible for the X-ray laboratory in Wannsee. How did you handle the lockdown? Our lab operations are geared to the experiment and, of course, only work when we are there. The instruments run in 365-7-24 mode and may only go into standby mode once before Christmas. With the corona lockdown, we had to close theRead More →
Inés is a mechatronics technician at BESSY II. In March she started to produce face masks with some of her colleagues in order to donate them to social institutions. The project masken.berlin has since then produced more than 1600 self-sewn masks. A few weeks ago the situation was quite different: In mid-March, the number of infections in Berlin rose daily in the triple digits, shops and schools were closed down, the newspapers were full of reports that doctors’ surgeries, hospitals and social institutions were lacking protective equipment of all kinds. Practically, not even a simple cloth mouth and nose protector could be found anywhere. DoRead More →
