Helmholtz-Zentrum Berlin (HZB) became a victim of a cyber attack on 15.06.2023. To protect against it, we have shut down all IT systems. The research centre cannot be reached via the website, email or telephone at the moment. We ask for your understanding.Read More →
Moses Oladele Alfred came to HZB on a Georg Forster Research Fellowship. The Nigerian chemist is an expert in low-cost materials for remediating environmental damage. But scientific expertise alone is not enough, he says: You also have to convince policymakers. He found support in a special program, training african scientists in communication and knowledge transfer. Read the full interview here >Read More →
Manuel Vasquez Montoya and Mayara da Silva are two PhD students at HZB. They have been selected this summer to participate in the Lindau Nobel Laureate Meeting and came back with new ideas and contacts. Among the highlights were the walks with Nobel Laureates in a small group. In this short interview they resume their experiences.Read More →
By Ulrike Goldenblatt > It was certainly the highlight of an evening on October 8th when pianist Einav Yarden took her seat at the Steinway piano and carried everyone present away with her interpretation of Robert Schumann’s “Kreisleriana”, inspired by a narration of E.T.A. Hoffmann. Not only could the crowd of science talents and their leading administrators plunge into the emotions that this 8-part composition evokes, but her explanations gave rise to a deeper understanding of her performance.Read More →
Some students overcame big obstacles to join the International Summer Students Programme at HZB: Traveling 12 hours by bus across the Andes to obtain a visa in Bogotá, borrowing money from here and there to pay the fees for formalities, and maintaining hope when the visa was delayed. One student visited the embassy every day for two weeks, leaving a yellow envelope with a polite reminder each time. And even with a visa, problems could arise last minute. Another student was already at the airport when he was denied boarding because he did not have a return ticket yet. He called our HZB colleagues whoRead 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 →
“The moment I stepped out of the lab, the sky above Berlin transformed. A sudden downpour ceased as swiftly as it had begun, leaving in its wake a vivid rainbow arching across the Berliner Himmel. It was my first unforgettable brush with the city’s “unberechenbar” weather—a local term for the unpredictable that I soon learned to embrace.” Having called two continents my home, I was now ready to immerse myself in the rhythm of a third. As summer unfolded, Berlin welcomed me—an eager research intern from distant shores, eager to dive into both the city’s vibrant culture and cutting-edge science.Read 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, Abdelrahman Mohamed Ishmael > My journey to Berlin started two years before joining HZB when I planned to get an international internship during my undergraduate life and worked strictly to make my dreams true. The first time I wandered Berlin streets, I was fascinated with its green natural sceneries and vibrant places inside. I felt no culture shock: What I have heard from travelers about the human and cultural diversity in Berlin has helped me cope more quickly as if I lived there before. Searching for stability I needed no time to get involved with the lab mates in the Young InvestigatorRead More →
By summer student Sofia Muñoz Bonilla > Dear summerstudents, My name is Sofia Muñoz Bonilla, I’m a Colombian student of environmental engineering. Thanks to the HZB summer program for foreign students, I have had a wonderful experience in Berlin. But I’m not going to talk about how amazing Berlin is, because you will find out for yourselves. However, with the eyes of an environmental engineer, I see important avenues with trees, the parks with their own vibes thanks to the many different musicians, green areas, and moss that grows in the middle of the sidewalks. The first days, I couldn’t believe how far my feetRead More →
By summer student Eduardo Montoya > Before coming to HZB, while having a coffee with one of my dearest friends who studied biomedical engineering, we got into jokingly into an argument of who was the most “engineer” out of the two of us. The big question was if she, having gone through a lot of electrical engineering, mechanical engineering programming and construction lectures, was the ultimate engineer. Or me, having studied materials sciences and engineering with my countless hours of solid states physics, thermodynamics and surface chemistry, was the ultimate engineer. I clearly lost this debate, and we came to the simple conclusion, that evenRead More →
