- Synchrotrons accelerate corona research
Synchrotron light sources were originally built to study particles. Today, they are even used in the fight against COVID-19. The projects are as diverse as the fields of the synchrotron users, who ... - Water as a metal
Every child knows that water conducts electricity - but this refers to "normal" everyday water that contains salts. Pure, distilled water, on the other hand, is an almost perfect insulator. It cons...
- Lossless transmission of signals
New experiments with magnetically doped topological insulators at BESSY II have revealed possible ways of lossless signal transmission that involve a surprising self-organisation phenomenon. In the... - Watching complex molecules at work
A new method of infrared spectroscopy developed at BESSY II makes single-measurement observation and analysis of very fast as well as irreversible reaction mechanisms in molecules feasible for the ... - Plants absorb lead from perovskite solar cells more than expected
Lead from metal-organic perovskite compounds can be absorbed particularly easily by plants. The bioavailability is significantly higher than that of lead from inorganic compounds as found in batter... - Nanoparticles can change cells
Nanoparticles easily enter into cells. New insights about how they are distributed and what they do there are shown for the first time by high-resolution 3D microscopy images from BESSY II. For exa... - On the road to non-toxic and stable perovskite solar cells
The promising halide perovskite materials for solar energy conversion show high efficiencies, but this comes at a cost: The best perovskite materials incorporate toxic lead which poses a hazard to ... - Catalysts: Efficient hydrogen production via structure
Regeneratively produced hydrogen is considered the ecological raw material of the future. In order to produce it efficiently by electrolysis of water, researchers today also investigate perovskite ... - Following the charging and discharging of silicon electrodes live
Using silicon as a material for electrodes in lithium-ion batteries promises a significant increase in battery amp-hour capacity.The shortcoming of this material is that it is easily damaged by the... - New class of materials for tomorrow's energy storage
Researchers at the Technische Universität Berlin (TUB) have created a new family of semiconductors, the properties of which were investigated by the Helmholtz-Zentrum Berlin (HZB). The researchers ... - Nanopatterns of proteins detected by cryo-electron microscopy
A team from Helmholtz-Zentrum Berlin (HZB) used cryo electron microscopy to detect regular, two-dimensional structures in the form of Pascal triangles in a shock frozen protein material. The sampl... - Corrosion-resistant electrodes for electrolytic splitting of water
As part of an international collaboration, a team at the HZB has examined the corrosion processes of high-quality BiVO4 photoelectrodes using different state-of-the-art characterisation methods. ...
- Milestone for bERLinPro: photocathodes with high quantum efficiency
A team at the HZB has improved the manufacturing process of photocathodes and can now provide photocathodes with high quantum efficiency for bERLinPro. Teams from the accelerator physics and the... - How could artificial photosynthesis contribute to limiting global warming?
If CO2 emissions do not fall fast enough, then CO2 will have to be removed from the atmosphere in the future to limit global warming. Not only could planting new forests and biomass contribute to t... - Water is more homogeneous than expected
In order to explain the known anomalies in water, some researchers assume that water consists of a mixture of two phases even under ambient conditions. However, new X-ray spectroscopic analyses at ... - X-ray analysis of carbon nanostructures helps material design
Nanostructures made of carbon are extremely versatile: they can absorb ions in batteries and supercapacitors, store gases, and desalinate water. How well they cope with the task at hand depends lar... - Catalyst research for solar fuels: Amorphous molybdenum sulphide works best
Efficient and inexpensive catalysts will be required for production of hydrogen from sunlight. Molybdenum sulphides are considered good candidates. A team at HZB has now explained what processes ta... - "Molecular scissors" against plastic waste
A research team from the University of Greifswald and Helmholtz-Zentrum-Berlin (HZB) has solved the molecular structure of the important enzyme MHETase at BESSY II. MHETase was discovered in bacter... - Copper oxide photocathodes: laser experiment reveals location of efficiency loss
Solar cells and photocathodes made of copper oxide might in theory attain high efficiencies for solar energy conversion. In practice, however, large losses occur. Now a team at the HZB has been abl... - Development of a miniaturised EPR spectrometer
Several research institutions are developing a miniaturized electron paramagnetic resonance (EPR) device with industrial partner Bruker to investigate semiconductor materials, solar cells, catalyst... - Radiography and Tomography of Egyptian Papyri
Researchers from the Egyptian Museum and Papyrus Collection, Berlin universities and Helmholtz-Zentrum Berlin studied a small piece of papyrus that was excavated on the island of Elephantine on the... - Nanoparticles in lithium-sulphur batteries detected with neutron experiment
An HZB team has for the first time precisely analysed how nanoparticles of lithium sulphide and sulphur precipitate onto battery electrodes during the course of the charging cycle. The results can ... - New sample holder for protein crystallography
An HZB research team has developed a novel sample holder that considerably facilitates the preparation of protein crystals for structural analysis. A short video by the team shows how proteins in s... - Dynamic pattern of Skyrmions observed
