International ECOSTORE project

The ECOSTORE project is now commencing under the coordination of scientists from the Helmholtz Zentrum Geesthacht with four million euro of funding from the European Commission. Several European and Japanese Institutes and companies are participating. In the course of this four year project, novel materials based on new types of boron and nitrogen compounds, will be investigated for hydrogen storage and batteries. more

Opening Event of the Helmholtz Graduate School

On Friday September 27th the opening event of the Helmholtz Graduate School for Macromolecular Bioscience will take place at the Free University of Berlin. Following welcoming words from the Scientific Director of the Helmholtz-Zentrum Geesthacht Prof. Dr. Wolfgang Kaysser and greetings from politics and science, the participants will get a brief introduction of the scientific work. 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

A new research programme to achieve an improved understanding of the Earth system for the Baltic Sea region

On June 10th, 2013, at the 7th Study Conference on BALTEX, a new international and interdisciplinary research programme, Baltic Earth, will be launched. The aim of Baltic Earth is to achieve an improved understanding of the Earth system for the Baltic Sea region, focusing on physical and biogeochemical processes which interact in the atmosphere, in the sea including sea ice, and on land. Human interactions with the environment are recognized as an important part of the regional Earth system. more

Sustainable use of the North Sea and the Baltic Sea: coastal researchers provide the basis for future protection of the marine environment.

In the next 3 years coastal researchers will closely examine the processes in the sea floors of the German sectors of the North Sea and Baltic Sea to provide a scientific basis for the implementation of the European Marine Strategy Framework Directive. The BMBF (Federal Ministry of Education and Research), is funding five collaborative projects which are now commencing their work. more

Geesthacht scientists reconstruct the climate of the past

Scientists of the Helmholtz-Zentrum Geesthacht are participating in the most comprehensive reconstruction to date of regional climatic changes over the past 2000 years. A team of 78 scientists from the international research project PAGES (Past Global Changes) has analysed climate data from seven continental regions for the study “Continental-scale temperature variability during the past two millennia”. The results of the study have recently been published in the journal “Nature Geoscience”. more

New Membrane Process: Geesthacht Researchers provide the desired polymer

Dr. Sofia Rangou, polymer scientist in Geesthacht, has succeeded in synthesizing the required starting product for a new process which has been developed by the University of Yale (USA) for the production of ultrathin membrane films from block copolymers. The highly-respected journal ACS-Nano recently published these results, which were achieved in cooperation with the University of Ioannina, Greece. more

An opening for molecules: Polymer research scientists develop double switchable membrane

Pharmaceutical residues in water can pose a danger to humans. Due to the fact that these molecules are soluble in water, there has been increasing evidence of their presence in groundwater for some years. Filtration is often very difficult as these trace substances are so minute. Such trace substances could be removed from the water with the use of new membranes developed by polymer researchers at the Helmholtz-Zentrum Geesthacht (HZG). more

A new generation of aircraft: Materials research scientists in Geesthacht are engaged in original scale research on joints

Joining technology specialists at the Helmholtz-Zentrum Geesthacht (HZG) are carrying out research on laser beam welding of a new aluminium-lithium alloy, within the research project LAWENDEL, which is part of the European Aeronautical Research Programme, Clean Sky. The long-term objective of the Clean Sky project is to build lighter and thus more environmentally friendly aircraft.

New center for neutron research in Germany:TUM and Helmholtz Centers establish the Heinz Maier-Leibnitz Zentrum

The German neutron research, concentrated at the Research Neutron Source Heinz Maier-Leibnitz (FRM II) in Garching, received its own name: Heinz Maier-Leibnitz Zentrum. Thus, the successful cooperation between the Technische Universitaet Muenchen (TUM), the Forschungszentrum Juelich and the Helmholtz-Zentrum Geesthacht – Center for Materials and Coastal Research (HZG) enters a new stage. Today, the inaugural ceremony was held in Garching. more
