ERM®-CC020
Starting material for the preparation of the new certified reference
material ERM®-CC020 was a mixture of river sediments. Certified values are
given for aqua regia extractable (ISO 11466) mass fractions of As, Cd, Co, Cr,
Cu, Hg, Ni, Pb, V and Zn. ERM®-CC020 is available as a powder with particle
sizes below 63 µm.

One major goal of the World Materials Research Institute Forum - WMRIF is to
promote young scientists in the field of materials science and engineering.
WMRIF regularly organises joint workshops among the member institutes. This
book comprises the peer-reviewed contributions during the 2nd International
Workshop for Young Materials Scientists at BAM.

Dr. Werner Daum
In 'Tomorrow today' Dr. Werner Daum answered questions on condition monitoring and structural health monitoring, for instance of aircrafts and bridges. The interview was broadcasted on Deutsche Welle TV on 29 August.

SPIN project participants
The SPIN research project “Spearhead Network for Innovative, Clean and Safe Cement and Concrete Technologies” comprises seven African nations and three European countries, working together in order to develop innovative, sustainable, safe and clean cement and concrete technology, adapted for conditions in Africa. SPIN aims to build an African expert network and to develop an African cement and concrete culture.

Observation of the formation of clathrates at ambient conditions
Scientists at BAM have succeeded in creating clathrate hydrates at ambient condition and studied this process at high temporal resolution. The new experimental approach was carried through at ESRF (European Synchrotron Radiation Facility, Grenoble, France) using an acoustic levitator to suspend microscopic volumes of dichloromethane in air. Clathrates spontaneously form in these suspended droplets when water is mixed in, because the surface of the droplets efficiently cools as the dichloromethane evaporates. Naturally occurring methane hydrates are of potential interest as alternative fuel sources.

Classification of solid oxidizers is performed according to the regulations on the transport of dangerous goods and according to the GHS, the Globally Harmonized System of Classification and Labelling of Chemicals. Test results of the UN test for oxidizing solids form the basis for classification. Certain problems have occured with this test, e.g. in terms of repeatability or reproducibility of test results, and the toxicity of the reference oxidizer potassium bromate. Hence, the IGUS EOS working group installed an ad-hoc working group assigned with the task to propose solutions for the existing problems. The suitability of the proposed solutions was proven by an interlaboratory comparison with 12 participating laboratories from industries and competent authorities. The results and recommendations of this comparison were published in a final report.

For the very first time, three-dimensional (3D) imaging of magnetic material structures is now possible. Detailed information of these structures – also known as domains – is of enormous importance for the development of magnetic memory and charging units.
Scientists of the BAM Working Group „X-ray topography“, together with colleagues of the HZB Helmholtz Centre Berlin, have developed a non-destructive visualisation technique for the micron- to millimetre-sized Weiss domains by combining a new measurement method and a new algorithm. They have devised an inverted Talbot–Lau neutron tomography which provides high-contrast images of the magnetic domains non-destructively.
Silicon compound; ball and stick model

A group of researchers with the collaboration of BAM has prepared and fully characterised the first base adducts of silicon tetraazide. The highly energetic compounds combine a remarkable thermal stability, with a high reactive nitrogen content (up to 48 %) and convenient accessibility.
These properties and because silicon is abundant, cheap and environmentally harmless, such adducts of silicon tetraazide are promising highly energetic materials. The safe and convenient synthesis of solutions of pure silicon tetraazide is a major progress which opens up a new route to a number of new nitrogen-rich compounds.
