At the 6th international conference "MECA SENS - Mechanical Stress Evaluation by Neutrons and Synchrotron Radiation" from the 7th to 9th of September more than 120 participants from 20 countries exchanged views on the subject of residual stresses. The event was organized by the Helmholtz-Zentrum Geesthacht. Residual stresses occur in the manufacture of components, for example, of aircraft and vehicles and can lead to their failure. Therefore, it is important to understand how internal stresses arise in production processes, how to avoid them or may even increase the lifespan of components. Residual stresses can be measured using neutron and synchrotron radiation, since these components enable the investigation of large components even during the production process.

This year “The Summer School on Coastal Research” will take place in Lauenburg und Büsum from the 19th to the 30th of September. In the course of this 12 day event the 20 participants will be brought up to date with the latest knowledge regarding climate change and its effects on the North Sea. The young marine and environmental scientists come from 15 countries, and yet all have one thing in common – their desire to investigate the coasts and seas of the world. Each year since 2002, the Institute of Coastal Research at the Helmholtz Centre Geesthacht, the Alfred Wegener Institute in Bremerhaven and the Leibniz Institute for Baltic Sea Research in Warnemünde have cooperated to organise a summer school on various topics regarding climate and marine research - originating from the idea of imparting the knowledge gained from current research to junior scientists from around the world.

When the wind blows and the sun shines, wind turbines and solar modules provide us with electricity. However, the energy yield is dependent on weather conditions. If the wind blows too strongly at night, for example, wind turbines sometimes have to be shut down, due to a lack of consumers. Should there be neither wind nor sun, urgently needed electricity may not be available. One way to employ renewable energy more effectively could lie in the utilization of hydrogen. Hydrogen would firstly be produced by using surplus supplies of electricity. When there is a renewed demand, this hydrogen could, in turn, be used to generate electricity e.g. in fuel cells. The benchmark for hydrogen technology is the storage. Researchers from Geesthacht presented their innovative storage concepts for the first time at the H2-Expo in Hamburg.
