On 19 February 2021, the 4000th eye tumour patient received irradiation with protons, performed by a joint team from Helmholtz-Zentrum Berlin (HZB) and Charité - Universitätsmedizin Berlin. The number of patients treated in 2020 remained at the previous year's level despite the more difficult corona conditions. The treatment in Berlin-Wannsee is only available for uveal melanomas of the eye. The proton accelerator at HZB is the only therapy site for this disease in Germany.
For more than 20 years, Charité - Universitätsmedizin Berlin and Helmholtz-Zentrum Berlin (HZB) have jointly offered irradiation of eye tumours with protons. For this purpose, the HZB operates a proton accelerator, while the medical care of patients is provided by the Charité.
"We congratulate the joint team on this great success and thank them for doing everything they could under the difficult pandemic conditions to maintain the operation of the life-saving eye tumour therapy," says Prof. Bernd Rech, spokesman for the scientific management of HZB.
500 to 600 people contract malignant uveal melanoma in Germany every year. In 97 percent of cases, the tumour can be completely destroyed by irradiation with protons. In most cases, not only the eye but also the vision can be preserved to a satisfactory degree. Radiation with protons is a particularly effective method: the energy of the proton beam can be adjusted in such a way that practically only the tumour receives the radiation, while the surrounding healthy tissue is spared.
- Five Berlin-based research institutions join forces in data-driven materials researchResearch data is regarded as key to materials research in the age of artificial intelligence (AI). Five Berlin-based research institutions have now signed a Memorandum of Understanding (MoU) to establish long-term collaboration in the fields of research data, data infrastructures and AI.
- New contact material boosts the efficiency of perovskite solar cellsA newly developed material for the electron contact improves the efficiency of single perovskite solar cells and perovskite/silicon tandem solar cells. The new material is based on a carborane molecule. It offers several advantages over the standard material C60, as shown by the study led by Steve Albrecht’s team. The new material has since been patented and is already commercially available.
- Precision interface chemistry pushes perovskite solar cells beyond 26% efficiencyAn international research collaboration has developed a new molecular strategy for controlling one of the most critical interfaces in perovskite solar cells. The resulting solar cells reached a power conversion efficiency of 26.19% in the n i p architecture, together with strong operational stability under prolonged illumination and elevated temperature. The results have been published in the Journal of the American Chemical Society.
