The study has now been published in the renowned journal Science.
- Tomography brings insights into the early evolution of bonesModern biology considers bone cells (osteocytes) as essential for bone development and health. However, when bone initially evolved some 400-million years ago, it did not contain bone cells. So why did bone cells evolve? Why was it so advantageous that most subsequent vertebrates have bone cells? A joint team of palaeontologists at Berlin’s natural history museum has now for the first time analysed these structures in 400 million-year-old fossils of marine life at unprecedentedly high resolution and in 3D. To be able to view these structures, tomography experts at the Helmholtz-Zentrum Berlin (HZB) examined the samples under the focussed ion beam of a scanning electron microscope to calculate 3D images from the data, achieving resolutions in the nanometre range using technology that was initially developed to study battery corrosion.

- Robust high-performance data storage through magnetic anisotropyThe latest generation of magnetic hard drives is made of magnetic thin films, which are invar materials. They allow extremely robust and high data storage density by local heating of ultrasmall nano-domains with a laser, so called heat assisted magnetic recording or HAMR. The volume in such invar materials hardly expands despite heating. A technologically relevant material for such HAMR data memories are thin films of iron-platinum nanograins. An international team led by the joint research group of Prof. Dr. Matias Bargheer at HZB and the University of Potsdam has now observed experimentally for the first time how a special spin-lattice interaction in these iron-platinum thin films cancels out the thermal expansion of the crystal lattice. The study has been published in Science Advances.

- On the road to non-toxic and stable perovskite solar cellsThe 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 the environment. To replace lead by less toxic elements is not easy since lead-free perovskites show lower stability and poor efficiencies. Now, an international collaboration has engineered a new hybrid perovskite material with promising efficiency and stability.
- Neutron research: Magnetic monopoles detected in Kagome spin ice systemsMagnetic monopoles are actually impossible. At low temperatures, however, certain crystals can contain so-called quasi-particles that behave like magnetic monopoles. Now an international cooperation has proven that such monopoles also occur in a Kagome spin ice system. Decisive factors were, among others, measurements with inelastic neutron scattering at the NEAT instrument of the Berlin neutron source BER II*. The results have been published in the journal Science.
- Fast and furious: New class of 2D materials stores electrical energyTwo dimensional titanium carbides, so-called MXenes, are being discussed as candidates for the rapid storage of electrical energy. Like a battery,MXenes can store large amounts of electrical energy through electrochemical reactions- but unlike batteries,can be charged and discharged in a matter of seconds. In collaboration with Drexel University, a team at HZB showed that the intercalation of urea molecules between the MXene layers can increase the capacity of such "pseudo-capacitors" by more than 50 percent. At BESSY II they have analysed how changes of the MXene surface chemistry after urea intercalation are responsible for this.

- The solar technologies race: thin-film photovoltaics are catching upZSW and HZB present current data – with new opportunities for Europe’s solar industry
- Doped organic semiconductors exploredOrganic semiconductor materials are already being employed today in solar cells and organic LEDs (OLEDs) amongst others. Until now, however, little was known about how the doping molecules are integrated into the chemical structure of organic semiconductors. The Molecular Systems Joint Research Team of the Helmholtz-Zentrum Berlin and Humboldt-Universität zu Berlin at BESSY II have now analysed this with surprising results. The molecules are not necessarily uniformly dispersed in the host lattice, as it is usual with inorganic semiconductors, but instead form what are known as co-crystallites. The doped organic semiconductor consists of a matrix of undoped crystallites in which such “mixed crystallites” are embedded. It is this very species that takes over the role as the actually doping molecule. The results were published in Nature Communications.

- Wheel with triple sound velocity for pulse selection at BESSY IIIn order to pick out only one pulse per turn out of the 400 possible x-ray flashes at BESSY II, a joint team of physicists and engineers from Forschungszentrum Jülich, MPI of Microstructure Physics and HZB have developed an extremely fast rotating “MHz-pulse selector”, which is now at the core of the Uppsala Berlin joint Lab to extract the hybrid bunch within the 200 nanosecond ion clearing gap of BESSY II. The device consists of a wheel made of a special Aluminum alloy which has tiny slits of 70 micrometer width at its outer rim. They move frictionless in a vacuum at triple sound velocity perpendicular to the beam. Users can now decide to operate their experiment in a single bunch mode even during normal multibunch operation of BESSY II.
- EU funding strengthens solar cell research at HZBMarcus Bär and his team are participating in two international projects being funded under the EU Horizon 2020 research programme.

- Learning by eye: silicon micro-funnels increase the efficiency of solar cellsA biological structure in mammalian eyes has inspired a team headed by Silke Christiansen to design an inorganic counterpart for use in solar cells. With the help of conventional semiconductor processes, they etched micron-sized vertical funnels shoulder-to-shoulder in a silicon substrate. Using mathematical models and experiments, they tested how these kind of funnel arrays collect incident light and conduct it to the active layer of a silicon solar cell. Their result: this arrangement of funnels increases photo absorption by about 65% in a thin-film solar cell fitted with such an array and is reflected in considerably increased solar cell efficiency, among other improved parameters.
- Stretch and relax! – Losing one electron switches magnetism on in dichromiumAn international team of scientists from Berlin, Freiburg and Fukuoka has provided the first direct experimental insight into the secret quantum life of dichromium. Whereas in its normal state the 12 valence electrons form a strong multiple bond between the two chromium atoms, removing only one electron changes the situation dramatically: 10 electrons localize and align their spins, thus resulting in ferromagnetic behavior of the dichromium-kation. The bonding is done by one electron only, resulting in a much weaker bond. The scientists used the unique Nanocluster Trap experimental station at the BESSY II synchrotron radiation source at Helmholtz-Zentrum Berlin and published their results in the Journal Angewandte Chemie.

- Details of a crucial reaction: Physicists uncover oxidation process of carbon monoxide on a ruthenium surfaceAn international team has observed the elusive intermediates that form when carbon monoxide is oxidized on a hot ruthenium metal surface. They used ultrafast X-ray and optical laser pulses at the SLAC National Accelerator Laboratory, Menlo Park, California. The reaction between carbon monoxide and adsorbed oxygen atoms was initiated by heating the ruthenium surface with optical laser pulses. Directly afterwards, changes in the electronic structure of oxygen atoms were probed via X-ray absorption spectroscopy as they formed bonds with the carbon atoms.The observed transition states are consistent with density functional theory and quantum oscillator models.

The first measurements of magnetic materials, spin systems, and nanostructured magnetic samples are scheduled for early 2015.

- Organic layer adds light particlesSolar cells can only use photons with energies above a specific threshold to generate electricity. A German-Australian research collaboration has now combined solar cells with an organic material which can “add up” low-energy photons to yield higher-energy light, which can then be harvested by the solar cell. In an invited review paper published in the prestigious journal Energy & Environmental Science the scientists give an overview on the fascinating phenomenon of photonic upconversion and report new results: The organic layers show less photo-degradation than suspected and may also be used for other optoelectronics applications.

- In Schwerelosigkeit Metalle geschäumtErfolgreich haben drei Forscher des Berliner Hahn-Meitner-Instituts (HMI) in Schwerelosigkeit untersucht, wie die Erdanziehung die Eigenschaften eines Metallschaums beeinflusst. Sie haben ihre Experimente in einem umgebauten Airbus 300 durchgeführt. Das Flugzeug fliegt auf einer Art Buckelbahn. Dabei steigt es immer wieder zunächst steil auf, um danach im freien Fall entlang einer Wurfparabel zu fliegen. Während eines solchen Fluges herrscht immer wieder kurzzeitig fast doppelte Erdanziehung, die von einer 20 Sekunden dauernden Phase der Schwerelosigkeit abgelöst wird.
- Qumran-Rollen vom Toten Meer an BESSY II untersucht
Antike Schriftstücke vor dem Verfall zu bewahren oder sie zu restaurieren ist eine Kunst für sich. Um sie auszuüben, ist es von enormer Bedeutung herauszufinden, wie beispielsweise Pergament durch bestimmte Tinten über die Jahrhunderte zerstört wird; und wie dies zu vermeiden wäre. Für solche Untersuchungen ist Röntgenstrahlung ein hervorragendes Werkzeug. Um diese Forschungsarbeiten zu unterstützen, hat BESSY nun einen Röntgenmessplatz so ausgestattet, dass auch sehr empfindliche Objekte, wie antike Pergamentrollen oder Gemälde auf Leinwand oder Holz untersucht werden können, ohne dabei Schaden zu nehmen.
