Scaled model of a gas turbine for power generation; completely manufactured with additive manufacturing technologies. Fraunhofer IFAM Dresden

Together with the H+E-Produktentwicklung GmbH in Moritzburg, Saxony, the Fraunhofer Institute for Manufacturing Technology and Advanced Materials IFAM in Dresden has developed a true-to-scale gas turbine that impressively demonstrates the current potentials and limitations of powder bed-based additive technologies. The technology demonstrator "Siemens SGT6-8000 H", a scaled model of a gas turbine for power generation on a scale of 1:25, was completely manufactured with additive processes except for the shaft.

At the International Symposium on Automotive Lighting 2019 (ISAL) in Darmstadt from September 23 to 25, 2019, the Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP, a provider of research and development services in the field of organic electronics, will present OLED light strips of any length with additional functionalities for the first time at booth no. 37.

Time-lapse images show that the enzyme ‘breathes’ during turnover: it expands and contracts aligned with the catalytic sub-steps. Its two halves communicate via a string of water molecules. Jörg Harms / MPSD

Researchers from the Department of Atomically Resolved Dynamics of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg, the University of Potsdam (both in Germany) and the University of Toronto (Canada) have pieced together a detailed time-lapse movie revealing all the major steps during the catalytic cycle of an enzyme. Surprisingly, the communication between the protein units is accomplished via a water-network akin to a string telephone. This communication is aligned with a ‘breathing’ motion, that is the expansion and contraction of the protein.

Scientists at Münster University investigate cells using dual-beam laser mass spectrometry:Cells are the basic building blocks of life. The chemical composition of cells can be determined by mass spectrometry. Scientists at the University of Münster present a method which has improved the spatial resolution of “MALDI” mass spectrometry by around one-thousandth of a millimetre. The results have been published in "Nature Methods".
