Dr. Tabitha A. Amollo is a researcher and lecturer at Egerton University in Njoro in Kenya. She holds a Ph.D. in physics from the University of KwaZulu-Natal, South Africa. Her research interests focus on developing cutting-edge nanomaterials for energy conversion devices including graphene nanomaterials. She published a number of articles in reputable journals. At Egerton University, she is the head of a young team to explore dye-sensitive solar cells, she is a chairperson of the Physics Department, and she coordinates the undergraduate program and gives lectures to undergraduates and postgraduate physics students. Here in Germany, there are not many women in physics. How is itRead More →

A group of 14 volunteers gathered one week on Zoom. From morning coffee until late in the night, they tackled intricate problems and worked out great solutions based on machine learning for digital twins of batteries or for predicting cracks in materials. “This year, we had the most successful hackathon so far, it was incredible,” says HZB data scientist Gregor Hartmann, who initiated the Hackathon. Many problems in research require a deep understanding of the material as well state of the art knowledge in methods of artificial intelligence. “You need this very close collaboration between the domain scientists and the data scientists, says Gregor Hartmann,Read More →

by summerstudent Oscar Moreno As a master’s student in chemistry, experiments are the basis of my research. The excitement of running an experiment for the first time and the challenge of trying to explain the results keeps me motivated. Nonetheless, in order to pursue things further, my investigation forced me to work during weekends and many times I found myself preparing reports in my room at midnight. I was not aware my acacemic life had come out of the laboratory and was encroaching on other aspects of my life until one of my advisors stopped me. After seeing me working on Saturdays without pausing, heRead More →

by summerstudent Nora Jung Sitting in my organic chemistry class two semesters ago, I heard the whispers of a word repeated often amongst my classmates. I was only in my second year of my undergrad and the pressure of finding a research position was a constant reminder in the back of my head. In January of 2022, I applied for the summer research position at HZB and it felt like a step in the right direction, but I was still unsure about what lay ahead. What does it mean to do research? Am I qualified enough? Will I know the right answers?Read More →

Recently, Lightsources.org asked scientists at light source facilities from all over the world to record a short video statement, pointing out why and how synchrotron light is useful for their research. The outreach campaign is featuring the variety of research done at light sources in a comprehensible way, easy to understand by all citizens. HZB chemist Marion Flatken took part. She is doing her doctorate on perovskite materials for solar cells in Antonio Abate’s team. Why did you take part in the #LightSourceSelfie campaign? For me it’s important to make transparent how we work in research. Actually, this is also in the spirit of HermannRead 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 →

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 →

I work at the EMIL beamline which is a very complex system. It provides light for the EMIL laboratory (Energy Materials In-situ Laboratory Berlin) by combining two undulators: UE48 for the soft X-ray range and cryo-cooled U17 for the hard X-ray range. It delivers an energy range from 80 eV to 10000 eV to five end-stations. It has ten mirror chambers to guide the light and three monochromators to select the required energies, and it has a length of 62 m while only 1 m width.Read More →
