Catalyst research for solar fuels: Amorphous molybdenum sulphide works best

08-Apr-2019

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 take place in molybdenum sulphides during catalysis and why amorphous molybdenum sulphide works ...

Water is more homogeneous than expected

22-Feb-2019

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 BESSY II, ESRF and Swiss Light Source show that this is not the case. At room temperature and normal ...

Blue phosphorus - mapped and measured for the first time

18-Oct-2018

Until recently, the existence of "blue" phosphorus was pure theory: Now an HZB team was able to examine samples of blue phosphorus at BESSY II for the first time and confirm via mapping of their electronic band structure that this is actually this exotic phosphorus modification. Blue phosphorus ...

Insight into catalysis through novel study of X-ray absorption spectroscopy

02-Aug-2018

An international team has made a breakthrough at BESSY II. For the first time, they succeeded in investigating electronic states of a transition metal in detail and drawing reliable conclusions on their catalytic effect from the data. These results are helpful for the development of future ...

How the internal compass is constructed in magnetotactic bacteria

19-Apr-2018

Magnetotactic bacteria are usually found in freshwater and marine sediments. One species, Magnetospirillum gryphiswaldense, is easily cultivated in the lab - with or without magnetic nanoparticles in their interior depending on the presence or absence of iron in the local environment. "So these ...

Better kesterite solar cells with germanium

03-Apr-2018

Specific changes in the composition of kesterite-type semiconductors make it possible to improve their suitability as absorber layers in solar cells. As a team at the Helmholtz-Zentrum Berlin showed, this is particularly true for kesterites in which tin was replaced by germanium. The scientists ...

Nanostructuring increases efficiency of metal-free photocatalysts by factor eleven

Solar–to-hydrogen conversion

02-Mar-2018

Polymeric carbon nitrides exhibit a catalytic effect in sunlight that can be used for the production of hydrogen from solar energy. However, the efficiency of these metal-free catalysts is extremely low. A team at the Tianjin University in China, in collaboration with a group at the ...

Ionic liquids simplify laser experiments on liquid samples

20-Oct-2016

An HZB team has developed a new approach to conduct photoemission spectroscopy of molecules in solution. This has been difficult up to now because the sample needed to be situated in vacuum – but liquids evaporate. The work has now demonstrated it is feasible to replace the solvent with an ionic ...

Lithium-ion batteries: Capacity might be increased by six times

10-Aug-2016

The capacity of lithium-ion batteries might be increased by six times by using anodes made of silicon instead of graphite. A team from the Helmholtz-Zentrum Berlin (HZB) Institute of Soft Matter and Functional Materials has observed for the first time in detail how lithium ions migrate into thin ...

Soft decoupling of organic molecules on metal

24-Jun-2016

An international team has discovered an elegant way to decouple organic nanosheets grown on metal surfaces. After iodine intercalation, measurements at the synchrotron source BESSY II of Helmholtz-Zentrum Berlin (HZB) showed that a network of organic molecules behaved almost as it was ...
