Total Reflection Mirrors: Nanostructures for X-ray Optics

Two silicon substrates are refined with state-of-the-art thin-film coatings for free-electron laser applications at the Deutsches Elektronen Synchrotron (DESY). Nanotechnologists from Geesthacht manufacture ultra-high precision X-ray optics for FLASH II required for this process. more

New licensee adopts “Made in Geesthacht” technology

The department of “Solid State Joining Processes” at the Helmholtz-Zentrum Geesthacht (HZG) has recently concluded a new cooperation agreement with the Spanish machine construction specialists, Loxin. Patented joining technologies, developed by Geesthacht materials research scientists, will thus be integrated into a wide range of technological applications throughout the world. more

Shipping emissions over the North Sea could increase twenty-five percent by 2030

Within the framework of the EU Clean North Sea Shipping project, Dr. Volker Matthias of the Helmholtz-Zentrum Geesthacht studied the current pollution emitted by commercial ships. Taking into account different scenarios, the coastal researcher also calculated possible future emissions. The models show that, without further legislative regulation and technical modifications to the vessels, the nitrogen oxide emissions from shipping traffic could increase twenty-five percent by the year 2030. more

Researchers develop ultrathin perfect UV light absorber

Ultraviolet light (UV) has not only harmful effects on molecules and biological tissue like human skin but it also can impair the performance of organic solar cells upon long-term exposure. Researchers of Kiel University and Helmholtz-Zentrum Geesthacht have now developed a so-called plasmonic metamaterial, which is compatible with solar technology and completely absorbs UV light – despite being only 20 nanometers thin. more

Baltic Sea Fund recognizes the impacts of climate changes on the Baltic Sea

Presse release Baltic Sea Fund: The Baltic Sea Fund delegation decided on its annual meeting to award Professor Hans von Storch from Hamburg, Germany, for his work on highlighting the impacts of climate change on the Baltic Sea. The Lasse Wiklöf parliamentarian prize is awarded to former Prime Minister and Speaker Paavo Lipponen. The Åland Award is given to entrepreneur Soile Wartiainen. The total prize sum is 33,000 euro. more

Hightech winner from Geesthacht: new technology for the bonding of plastic and metal

Dr. Sergio Amancio, research group leader at the Helmholtz Zentrum Geesthacht and junior professor at the Technical University of Hamburg-Harburg, has become the “German High Tech Champion 2013 in Lightweight Design”. He was recently honoured for the development of a new joining technology, Friction Spot Joining (FSpJ) which enables the joining of metal and plastic – without the use of adhesives. more

Geesthacht coastal research scientist finds evidence of new type of flame retardant in eels

Within the scope of her doctoral thesis, Roxana Sühring from the Institute of Coastal Research at the Helmholtz-Zentrum Geesthacht is examining how flame retardants accumulate in the fatty tissue of eels. The special focus hereby is on emerging flame retardants being used to replace chemicals which have already been banned. Ms Sühring found evidence of both the banned and new types of flame retardants in all the eel tissue samples which she examined – in some cases in high concentrations when compared to the rest of Europe. The results have been published in the scientific journal “Chemosphere”. more

X-ray experiment reveals kinship of 150 million-year-old dinosaur eggs

A team of international research scientists have carried out some very detailed synchrotron radiation examinations on fossils, using two beamlines of the Helmholtz Zentrum Geesthacht (HZG) in Hamburg. The results regarding the evolution of dinosaur eggs were recently published in Nature Scientific Reports. more

Abb. 1: In dem Modell einer Fensterjalousie werden die Temperatur-Gedächtnis Polymer-Aktuatoren zum temperaturabhängigen Öffnen und Schließen der Lamellen genutzt. Der Temperaturbereich, in dem sich die Lamellen der Jalousie bewegen, ist programmierbar. Diese Fähigkeit wird als Temperatur-Gedächtnis bezeichnet.

First shape-memory plastics able to reverse deformation

Biomaterial researchers in Teltow have developed plastics that can repeatedly change from one shape to another and then back again when temperatures fluctuate within a selected range. The material, dubbed “polymer actuators” by its creators, thus overcomes a major limitation that affects similar materials. Up until now, polymers with temperature-controlled shape memory could only change form once. more
