From laboratory to everyday life: UVC LEDs for disinfection on the way to widespread use
International research team publishes overview of the state of the art of commercial UVC LEDs:
An international team of researchers has, for the first time, comprehensively assessed the state of the art of commercial UVC LEDs and summarized the findings in an open-access review. These compact, efficient, and…
IKZ launched four start-up companies in current evaluation period
The start-ups focus on advanced materials, precision instrumentation, and AI-supported data management:
During the evaluation period from 2019 to 2025, the Leibniz-Institut für Kristallzüchtung (IKZ) has initiated four spin-offs. These spin-offs are a crucial part of technology transfer, as they translate research…
HZB team investigates lithium-sulphur batteries in real-time
Findings are helpful to design compact Li-S batteries with a high energy density:
Using a non-destructive method, a team at HZB investigated practical lithium-sulphur pouch cells with lean electrolyte for the first time. With operando neutron tomography, they could visualise in real-time how the…
MXene as a frame for 2D water films shows new properties
Research team investigates phase changes of confined water at BESSY II:
An international team led by Dr. Tristan Petit and Prof. Yury Gogotsi has investigated MXene with confined water and ions at BESSY II. In the MXene samples, a transition between localised ice clusters to…
Ten thousand molecules in time
Experiments at Max Born Institute on generating and controling collective vibrations in a liquid:
The ultrafast placement of an electron in a polar liquid generates collective molecular vibrations in a spherical nano-volume. The vibrations change the diameter of this sphere periodically for more than 100…
New method for the mechanical formation of three-dimensional molecular structures
HU researchers develop light-powered nano-motor and use it to create ring-shaped, intertwined molecules:
Threads or ropes can easily be used for braiding, knotting, and weaving. In chemistry, however, processing molecular strands in this way is an almost impossible task. This is because molecules are not only tiny, they…
Research team succeeds in controlled formation of skyrmion bags
The complex structures in thin ferromagnetic materials are important for future spintronic devices:
A team of researchers at the Max Born Institute and collaborating institutions has developed a reliable method to create complex magnetic textures, known as skyrmion bags, in thin ferromagnetic films. Skyrmion bags…
Scrolls from Buddhist shrine virtually unrolled at BESSY II
HZB team used 3D X-ray tomography and AI for non-destructive investigation:
The Mongolian collection of the Ethnological Museum of the National Museums in Berlin contains a unique Gungervaa shrine. Among the objects found inside were three tiny scrolls, wrapped in silk. Using 3D X-ray…
Advancing time-resolved X-ray science
Novel method gives researchers insight into ultrafast processes and dynamics of materials:
An international team of researchers around IKZ scientist Dr. Peter Gaal has demonstrated a novel approach to time-resolved X-ray diffraction, combining advanced Hadamard timing schemes with a novel device called the…
Targeted elimination of hospital germs
Ferdinand-Braun-Institut developed new far-UVC LEDs against multidrug-resistant organisms:
Newly developed far-UVC LEDs from the Ferdinand-Braun-Institut that are based on the micro-LED concept deliver record-breaking performance. They pave the way for compact, fiber-coupled medical light sources that can…
How quantum particles communicate
Nanophysicist Günter Kewes brings complex physics to life during Berlin’s Long Night of the Sciences:
We owe solar panels, smartphones, MRI scanners, and even supermarket barcode readers to quantum physics. For this reason, the UN General Assembly has declared 2025 the International Year of Quantum Science and…
FBH and HU strengthen cooperation in quantum technologies
Another Joint Lab launched / New professorship for Integrated Quantum Sensors:
With the new Joint Lab Integrated Nonlinear Quantum Optics, the Ferdinand-Braun-Institut (FBH) and Humboldt-Universität zu Berlin are strengthening their strategic partnership in the emerging field of quantum…
4-Inch Aluminum Nitride Crystals for Future Markets in Power Electronics and UV Photonics
Innovation project launched by IKZ, PVA TePla AG and Siltronic AG:
Three leading players in semiconductor research and development – the Leibniz-Institut für Kristallzüchtung (IKZ), the PVA TePla AG, and the Siltronic AG – are combining their expertise in a pioneering project to…
Marco Stucki wins Berlin University Alliance ideas competition
His quantum research project ‘Sawfish Cavity’ is now being used for a poster campaign in Berlin:
Marco Stucki has won the Berlin University Alliance's open knowledge lab competition with a novel process for manufacturing tiny diamond structures for quantum technologies. “Art meets Science” was the motto under…
MAX IV and BESSY II initiate new collaboration to advance materials science
Helmholtz-Zentrum Berlin signed a 5-year cooperation agreement with the Swedish national synchrotron laboratory MAX IV:
Swedish national synchrotron laboratory MAX IV and Helmholtz-Zentrum Berlin (HZB) with BESSY II light source jointly announce the signing of a 5-year Cooperation Agreement. The new agreement establishes a framework to…
