Science produces fascinating images. For two weeks, the most beautiful scientific images were exhibited in the foyer of the BESSY II X-ray source in Berlin-Adlershof. But it’s about much more than aesthetics: Helmholtz Imaging offers a great network that bundles expertise in imaging. Researchers benefit from this unbureaucratically and completely free of charge. Philipp Heuser from Helmholtz Imaging told me exactly what’s behind it during a roadshow at HZB.Read More →

A photostory at the end of this text reports about a special workshop at BESSY II. It was mid of november, in the night from sunday to monday, when a couple of accelerator scientists from MAX IV, BESSY II, CERN, KARA at KIT and DELTA from TU Dortmund gathered in the control room of BESSY II. They wanted to explore the so called two orbit or TRIBS modus in which one synchrotron could deliver two different sorts of light pulses. But let’s start with a short introduction: A Synchrotron Lightsource is a wonderful toolbox for doing research: it produces brilliant light pulses mostly in theRead More →

Nanoparticles are tiny, really tiny. Only a fraction of a micrometer or some nanometers in size. And only some thousands of molecules strong,  their properties can differ dramatically from those of their larger cousins. Titaniumdioxide, a whitish powder, can form such nanoparticles. In water, these nanoparticles can act as catalysts, when excited with light. and facilitate water splitting or water remediation. However, what happens exactly when TiO2 and water get into contact and which impact this is having on the electronic structure of TiO2 remained in the dark: it is very tricky to probe nanoparticle–water interface experimentally and to observe changes. Soft X-rays at BESSYRead More →

Source: SESAME Thursday, November 23, 2017:  At 10:50 yesterday morning scientists at the pioneering SESAME light source saw First Monochromatic Light through the XAFS/XRF spectroscopy beamline. This signals the start of the laboratory’s experimental programme. The beamline delivers X-ray light that will be used to carry out research in areas ranging from solid state physics to environmental science and archaeology. “After years of preparation, it’s great to see light on target,” said beamline scientist Messaoud Harfouche. “We have a fantastic experimental programme ahead of us, starting with an experiment to investigate heavy metals contaminating soils in the region.” Two beamlines for a start, a third one inRead More →
