An X-ray lens focuses the SLS light beam to 30 nanometres. This allows the measuring of chemical maps on the nanometre scale. Such analyses serve materials science in the study of magnetism in nanostructures, which could ultimately lead to new magnetic storage systems.
Environmental science will also benefit from the POLLUX beamline. For example the study of millions of year-old pollen which holds secrets of the earth’s history and the process of fossilisation. Fine particulate matter or aerosol particles can be made visible and their chemical composition and reactivity can be analysed.
One technical challenge at POLLUX is to focus the 30 nanometre X-ray beam on the sample between the Fresnel zone plates. These X-ray lenses have the diameter of a human hair, (0.15 millimetres) and consist of many hundreds of concentric gold rings created by a nano-lithographic process.
The new beamline is a joint project of the University of Erlangen-Nuremberg and PSI. The financing of 1.6 Million Euros comes from PSI and the German Federal Ministry of Education and Research. This is the tenth beamline for the five year-old SLS, and ten more beamlines are planned.

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
