T1 - Certification report for the reference materials ERM-AE102a, -AE104a, -AE120, -AE121 and -AE122 N2 - Isotope reference materials are essential to enable reliable and comparable isotope data. Besides the correction of mass fractionation or mass discrimination isotope reference materials are indispensible for validation and quality control of analytical procedures. This article describes the production and certification of a set of five isotope reference materials ERM-AE102a, 104a, AE120, 121 and 122, for boron isotope analysis. The isotopic composition of all materials has been adjusted by mixing boron mother solutions enriched in 10B or 11B with a boron mother solution having natural-like isotopic composition under full gravimetric control. All mother solutions have been analysed for their boron mass fraction as well as their boron isotopic composition by TIMS using IDMS as calibration technique. For all five reference materials the isotopic composition obtained on the basis of the gravimetric data agrees very well with the isotopic composition obtained from different TIMS techniques. Performed stability and homogeneity studies show no significant influence on the isotopic composition as well as on the related uncertainties. The certified isotope abundances for 10B are 0.29995 (27) for ERM-AE102a and 0.31488 (28) for ERM-AE104a. The certified δ11B values are -20.2 (6) ‰ for ERM-AE120, 19.9(6) ‰ for ERM-AE121 and 39.7 (6) ‰ for ERM-AE122. Together with the formerly certified ERM-AE101 and -AE103 a unique set of seven certified reference materials (CRM) for boron isotope analysis is now available from BAM.

A1 - Rockmann, R. T1 - Reliable information on solids from liquid-Phase adsorption N2 - For the characterization of disperse and porous solids, usually single gas adsorption(GA) is employed. In the case of liquid adsorption (LA), the extraction of information on solids immediately becomes a more sophisticated matter since information on geometric as well energetic parameters of the solids is both superposed by liquid-mixture effects and displayed in excess terms. We have to ask if reliable solid parameters can be also obtained from LA isotherms. The enlarged data bank of gas and liquid adsorption measurements enables us to change systematically solid parameters (e.g., the pore width of MCM-41, the pore entrances of SBA-16, chemical heterogeneity) and to study in this way the influence of solid parameters on LA.

Design type tests according to the international regulations for the transport of dangerous goods - drop test, stacking test, hydraulic pressure test and leakproofness test must be performed for every design type and manufacturer. The properties melt flow rate (MFR), relative density (D), low temperature notched Impact strength (N.I.S.) at -30 °C, environmental stress crack resistance (FNCT) and resistance to oxidative degradation Ox by nitric acid (determined by the increase of MFR) have been selected together with the corresponding test methods and tolerances for a comparison of polyethylene grades of one design type in the procedural rule on suitability proof for alternative plastic resins used for dangerous goods packagings and intermediate bulk containers (IBCs) – EN 15507. We wanted to proof the practical relevance of this standard by comparing the relationship between the results of the FNCT and the times to failure of design types in stacking tests with wetting solution and normal butyl acetate saturated wetting solution.

T1 - Nanoparticle factories: Biofilms hold the key to gold dispersion and nugget formation N2 - Biofilms living on gold (Au) grains play a key role in the biogeochemical cycle of Au by promoting the dispersion of Au via the formation of Au nanoparticles as well as the formation of secondary biomorphic Au. Gold grains from Queensland, Australia, are covered by a polymorphic, organic-inorganic layer that is up to 40 μm thick. It consists of a bacterial biofilm containing Au nanoparticles associated with extracellular polymeric substances as well as bacterioform Au. Focused ion beam (FIB) sectioning through the biofilm revealed that aggregates of nanoparticulate Au line open spaces beneath the active biofilm layer. These aggregates (bacterioform Au type 1) resulted from the reprecipitation of dissolved Au, and their internal growth structures provide direct evidence for coarsening of the Au grains. At the contact between the polymorphic layer and the primary Au, bacterioform Au type 2 is present. It consists of solid rounded forms into which crystal boundaries of underlying primary Au extend, and is the result of dealloying and Ag dissolution from the primary Au. This study demonstrates that (1) microbially driven dissolution, precipitation, and aggregation lead to the formation of bacterioform Au and contribute to the growth of Au grains under supergene conditions, and (2) the microbially driven mobilization of coarse Au into nanoparticles plays a key role in mediating the mobility of Au in surface environments, because the release of nanoparticulate Au upon biofilm disintegration greatly enhances environmental mobility compared to Au complexes only.

T1 - Structure and function of the universal stress protein TeaD and its role in regulating the ectoine transporter TeaABC of halomonas elongata DSM 2581T N2 - The halophilic bacterium Halomonas elongata takes up the compatible solute ectoine via the osmoregulated TRAP transporter TeaABC. A fourth orf (teaD) is located adjacent to the teaABC locus that encodes a putative universal stress protein (USP). By RT-PCR experiments we proved a cotranscription of teaD along with teaABC. Deletion of teaD resulted in an enhanced uptake for ectoine by the Transporter TeaABC and hence a negative activity regulation of TeaABC by TeaD. Atranscriptional regulation viaDNA binding could be excluded. ATP binding to native TeaD was shown by HPLC, and the Crystal structure of TeaD was solved in complex with ATP to a resolution of 1.9 A ° by molecular replacement. TeaD forms a dimer-dimer complex with one ATP molecule bound to each monomer, which has a Rossmann-like R/β overall fold. Our results reveal an ATP-dependent oligomerization of TeaD, which might have a functional role in the regulatory mechanism of TeaD. USP-encoding orfs, which are located adjacent to genes Encoding for TeaABC homologues, could be identified in several other organisms, and their physiological role in balancing the internal cellular ectoine pool is discussed.

T1 - EBSD Pattern Quality and its Use in Evaluating Sample Surface Condition N2 - Modern EBSD systems perform diffraction pattern “quality” (PQ) calculations, essentially measurements of the contrast of the brighter bands in the pattern above background, for every pattern analyzed. Since the calculations are independent of EBSD indexing, data are generated from all points on the analyzed sample surface, regardless of indexability or the state of the material beneath. EBSD maps generated from PQ data are like microstructurally sensitive SEM images, collected at EBSD speeds and grid resolutions, with contrast arising from phase density, crystal structure, crystallographic orientation, grain boundary location, near-surface plastic strain, coating density/thickness, and to some extent topography. Grain boundaries and other aspects of sample microstructure are readily revealed, so the PQ map is a very useful characterization tool in its own right, and serves as a reference for EBSD maps generated from indexing-derived data, such as orientation, grain boundary character, phase distribution and strain maps.

The diffraction patterns are often interpreted by superimposing individual Kikuchi bands which are geometrically described by band edges derived from Braggs law. For the typically very simple crystal structures of technically applied materials, such a simplification of the Kikuchi pattern interpretation works sufficiently well, especially for orientation determinations as a main application of EBSD. The more complex crystal structures, however, are a challenge for EBSD indexing routines which in such cases often fail unpredictably. The use of only the intensities of single reflectors for a description of the Kikuchi band intensity and as a cut-off criterion for a pre-selection of the strongest bands are not satisfactory. Often the result will match too many phases, or there are certain deviations in the intensity prediction which must be adapted manually. This is already problematic if one is absolutely sure that the patterns are originating from the expected phase and it becomes a very questionable procedure for an unknown phase.

Denn nur wenn die Lage der für die Standsicherheit wichtigen Bewehrung bekannt ist, können Kernbohrungen oder Sägearbeiten schadensfrei durchgeführt werden. Das Bodenradar als zerstörungsfreie Methode ist wegen des einfachen Verfahrens der Antenne entlang einer Messspur für eine solche Aufgabenstellung sehr gut geeignet. Die Anwendung kann aber eingeschränkt werden, wenn die gesuchte Bewehrung zu tief liegt oder durch eine davor liegende Bewehrung abgeschattet wird. Bei der Ortung mehrlagiger Bewehrung ist es wichtig, einen mehrstufigen und effizienten Messplan zu erstellen, der den Aufwand auf einem vertretbaren Maß beschränkt und die Möglichkeit bietet, beim Erreichen der Verfahrensgrenzen rechtzeitig die Untersuchung abzubrechen. Am Beispiel einer Stahlbetonbrücke, die nachträglich mit externen Spanngliedern versehen wurde, wird das Vorgehen beim Orten von mehrlagiger Bewehrung gezeigt.
