EU project CALIPSOplus has started for free access to European light sources
Light sources collaborating in CALIPSOplus
The EU is providing ten million euros in funding for the project CALIPSOplus, submitted by 19 European light sources. The project consortium, of which Helmholtz-Zentrum Berlin is a member, kicked off on May 2017. CALIPSOplus is aimed at promoting the international exchange of scientists and transnational access to the light sources in Europe. Other priorities are to integrate the relatively less active regions of Europe and to initiate research projects with small and mid-sized companies.
CALIPSOplus has a runtime of four years and is coordinated by Helmholtz-Zentrum Dresden-Rossendorf. In the scope of CALIPSOplus, HZB manages the work package “Dissemination and Training” and is involved in the research project MOONPICS on the metrology of nanometre lenses.
The project partners will be taking targeted measures to advertise the outstanding analytical methods available here to researchers from Central and Eastern Europe who have so far rarely used the European light sources. This will help to integrate them more strongly into the European scientific landscape. “It is important that we approach the scientists from these countries in person, locally, and promote the opportunities at the light sources. So it’s great that the training programme is one of the priorities of CALIPSOplus,” says Dr. Antje Vollmer, who is coordinating the activities for HZB and who manages user coordination at HZB. Among other things, HZB is planning workshops at universities of the 13 youngest EU countries. Furthermore, there will be a “twinning and exchange programme” that will invite scientists from these countries to collaborate on an equal footing with experienced users of light sources.
The kick-off event for CALIPSOplus was held at Helmholtz-Zentrum Dresden-Rossendorf (HZDR) on 18 and 19 May 2017. More information

Energy of charge carrier pairs in cuprate compounds
High-temperature superconductivity is still not fully understood. Now, an international research team at BESSY II has measured the energy of charge carrier pairs in undoped La₂CuO₄. Their findings revealed that the interaction energies within the potentially superconducting copper oxide layers are significantly lower than those in the insulating lanthanum oxide layers. These results contribute to a better understanding of high-temperature superconductivity and could also be relevant for research into other functional materials.

Electrocatalysis with dual functionality – an overview
Hybrid electrocatalysts can produce green hydrogen, for example, and valuable organic compounds simultaneously. This promises economically viable applications. However, the complex catalytic reactions involved in producing organic compounds are not yet fully understood. Modern X-ray methods at synchrotron sources such as BESSY II, enable catalyst materials and the reactions occurring on their surfaces to be analysed in real time, in situ and under real operating conditions. This provides insights that can be used for targeted optimisation. A team has now published an overview of the current state of knowledge in Nature Reviews Chemistry.

BESSY II: Phosphorus chains – a 1D material with 1D electronic properties
For the first time, a team at BESSY II has succeeded in demonstrating the one-dimensional electronic properties in phosphorus. The samples consisted of short chains of phosphorus atoms that self-organise at specific angles on a silver substrate. Through sophisticated analysis, the team was able to disentangle the contributions of these differently aligned chains. This revealed that the electronic properties of each chain are indeed one-dimensional. Calculations predict an exciting phase transition to be expected as soon as these chains are more closely packed. While material consisting of individual chains with longer distances is semiconducting, a very dense chain structure would be metallic.
