Many at HZB will still remember him. Between 1982 and 2008, Professor Helmut Tributsch played a key role in establishing solar energy research at the former Hahn-Meitner Institute. He authored over 450 publications in renowned journals and several books. Since retiring, he has been living on a farm in Italy, immersing himself in the questions that have preoccupied him since his student days. Antonia Rötger spoke with the physicist. Professor Tributsch, in your new popular science book, you criticise how modern physics deals with the concept of time. Why? Physics has made a fundamental mistake: it has ignored the irreversible, energy-driven time that we experience,Read More →

By summerstudent Amina Shahid > It all started on a seemingly ordinary summer day in 2024. I was scrolling through my phone when I saw a friend’s status, an awe-inspiring picture taken from the top of a scenic hill. Instantly, I asked, “Where is this place?” His answer sparked a wish in me: “I wanna be there one day!” Days later, while reading The Alchemist, I came across the line: “When you want something, all the universe conspires in helping you to achieve it.” – Paulo Coelho That quote didn’t just inspire me, it ignited something deeper. I made a heartfelt dua (prayer), and slowly,Read More →

By summer student Nargis Kholmamatova > Remember the money that you spend to pay water bills: do you know where it goes? While it is different from country to country, the general distribution process should be the same. First, a portion of your money is spent to pretreat the river water to make it safe to drink for you. Second, it covers post-treatment of your wastewater to safely return it to the environment. Lastly, the rest of your bills are spent for the maintenance of all of the equipment that is used to keep the whole water treatment system running. The water itself, as aRead More →

By summer student Qiujing Gou > As society transitions toward large-scale adoption of green energy, we need high-performance batteries to store electricity. Lithium-sulfur (Li-S) batteries, owing to their high theoretical energy density (>1000 Wh/kg vs. approximately 250 Wh/kg for state-of-the-art lithium-ion batteries) and the low-cost and abundance of sulfur, are considered to be one of the most promising technologies for next-generation energy storage solutions. My research at HZB During the summer school at HZB, I investigated a novel water-based biopolymer binder, chitosan for the sulfur cathode. Chitosan, made from seafood waste, is an eco-friendly material. Through modification, it becomes water-soluble and more suitable for lithium-sulfurRead More →

By summer student Mehdi Belbekouche > “Hallo” was the first German word I learned, and thanks to HZB, I’ve had the chance to learn much more about the German language and Germany itself. Although in the beginning, I mostly said “HALLO” then communicated in English, by the end, I was always proud to say “DANKE,” feeling like I truly knew how to speak German.Read More →

By summerstudent Yara Mahboub > I am Yara, a bachelor student in my 5th year of the nanoelectronics engineering program, and I joined a whole team of physicists. I guess if there was a reason that made Facebook invent the ‘it’s complicated’ status, it would definitely be to describe the physicists/engineers’ relationship.Read More →

Science produces fascinating images. For two weeks, the most beautiful scientific images were exhibited in the foyer of the BESSY II X-ray source in Berlin-Adlershof. But it’s about much more than aesthetics: Helmholtz Imaging offers a great network that bundles expertise in imaging. Researchers benefit from this unbureaucratically and completely free of charge. Philipp Heuser from Helmholtz Imaging told me exactly what’s behind it during a roadshow at HZB.Read More →

The Helmholtz-Zentrum Berlin (HZB) has long-standing cooperations with research institutions in Israel, often leading to close friendships over the years. One such friendship developed with David Cahen. As a renowned Professor of Chemistry, Physics and Material Research (emeritus), he runs a group at the Weizmann Institute of Science (and at Bar Ilan University) in Israel, where he works today on sustainable materials for energy conversion, especially Solar Cells. At the end of his fellowship at HZB in the month of September 2023, he told Ulrike Goldenblatt what he took away from his time in Berlin. (Please note, this interview was held before the atrocious terroristRead More →

The Intersolar trade fair, held in Munich from June 14th to 16th, served as a global platform for experts, industry leaders, and enthusiasts to explore the latest developments in the solar energy sector. Intersolar is part of “The smarter E,” four different exhibitions, Intersolar, ees, Power2Drive and EM-Power, focusing on renewable energy and highlighting groundbreaking advancements in the field – this year under the motto: “Creating a new energy world”. Helmholtz-Zentrum Berlin (HZB), participates every year to Intersolar and presents its research expertise and technological achievements. The HZB booth at Intersolar Europe 2023 At HZB’s booth this year, we presented the main aspects of ourRead More →
