Many colleagues are currently working in their home offices. During the corona break we shift the “floor conversations” into the digital world. Today we ask Ivona Kafedjiska. She is a doctoral researcher at PVcomB. She works on tandem solar cells in the HySPRINT laboratory and in the CISSY-Lab. She is also one of the doctoral representatives (speakers for) of the HZB PhD network. How do you spend your day? Right now I am in the kitchen doing this Skype interview. But actually I work at my desk in the bedroom. In the evening I read or do some art, but we also often do puzzles,Read More →

By Annette Friedrich In science, more and more publications are Open Access, i.e. accessible to everyone without payment barriers. Also at the HZB, scientists are encouraged to publish Open Access. “Green” road to Open Access Most scientists  prefer the “green road” to Open Access: They publish their paper in a journal under payment restrictions and after an embargo time (6 to 12 months), deposit the manuscript (pdf without the layout oft he journal) in the repository of their research institute. After the embargo time, their „green Open Access“ paper can be viewed by everybody free of charge. Multitude of repositories Research institutions and universities aroundRead 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 →

“Be a diamond. Flourish under pressure” – Maureen Joyce Connolly To most people diamonds are well-known as the marvelous gemstones which used in a piece of jewelry. However, they are not only “a girl’s best friends”. Due to their remarkable physical and optical properties diamonds can be used by scientists and engineers as well! With this blogpost I’ll guide you through my research here at HZB and, hopefully, will share the delight and enjoyment of working with diamonds. Why diamonds? To have a better understanding of diamond it is useful to have a look at its crystalline structure. The strong sp3 covalent bonds between carbonRead More →

Science Without Borders: Impressions from the 69th Lindau Nobel Laureate Meeting (2019) Guestpost by Jian Ren As a doctoral researcher in Helmholtz-Zentrum Berlin, I have been offered many opportunities to expand my horizons by working in an optimal international research environment and by participating in international conferences. Recently, I received another gift from HZB – I was nominated and financially supported by HZB to take part in the Lindau Nobel Laureate Meetings. 580 young scientists meet Nobel Laureates The Lindau Nobel Laureate Meetings have become an event of great importance for the exchange between generations of scientists each summer since 1951. In this year, theRead More →

By Elżbieta Wątor How to get back to BESSY II ? From Kraków where I study, it’s really easy. By car – it’s around 6 hours and the route is quite convienient. There is also a Ryanair flight to Berlin Schönefeld every morning or Flixbus several times per day. But how to organise that? Here’s my brief story: My participation in the 2017 Summer Student Programme was a happy coincidence. In November 2016 I took part in a small student seminar at Jagiellonian University in Krakow, Poland, where Rafał Piwowarczyk (a summer student in MX group at BESSY II in 2016) talked about his stayRead More →

At HZB about 150 young scientists are working on their doctoral dissertation. 81 come from abroad to Berlin to do their PhD in the HZB labs in Wannsee or Adlershof. The PhD students at HZB have organized themselves: twice a month, they invite to an informal get-together, they plan workshops and an annual PhD retreat in a country hotel in Brandenburg. This is actively supported by the management. I recently asked Daniel Meza, one of eight current doctoral student representatives about their activities. Daniel, why do you work as a representative in the PhD students organization ? Daniel: Maybe it’s a bit romantic, but forRead More →

Quantum Mechanics Can Be Useful Too! Nowadays, it seems that quantum mechanics is seen more as “spooky” than practical. Thus, I am here to “de-mystify” some of the science behind a fascinating process that’s yet to be simulated properly. My research group investigates the theory behind what is called Interatomic Coulomb Electron Capture (ICEC). This fascinating universal quantum process is yet to be fully understood, and we are here to change that. Someday, this could be an incredibly useful tool to revolutionize atomic and quantum chemical energy transfers. ICEC In A Nutshell The general process includes 3 main steps that occur simultaneously. We’ve got two atoms, atom A andRead More →

In chemistry, working up a synthesis route or a method which leads to the favored product is a challenging, lengthy procedure. Most of the time it is based on the concept “trial and error” and a lot is discovered by coincidence. For instance, the today’s industrial processes hydroformylation and the Czochralski process have their roots in accidental discoveries and very precise observation. Before a synthesis method becomes a large industrial process the synthesis must be optimized in a much smaller scale. That happens in the laboratory and is an odyssey that includes varying different parameters. Chemists refer to their work in the laboratory as “cooking”.Read More →
