  • Publication number: 20150090074
    Abstract: The invention refers to a method for manufacturing a three-dimensional metallic article/component made of a Ni-, Co-, Fe-based superalloy or combinations thereof, entirely or partly, by a powder based additive manufacturing process. During the step of performing powder melting by scanning a dual laser setup is used, where two laser beams of different beam properties are combined in the same machine and by adjusted beam profiling and integration of a suitable beam switch in a controlled manner a switching between two different laser beam diameters is performed. In each layer the laser beam with the smaller diameter scans the whole area and in every kth layer, with k>1, the laser beam with the larger diameter scans the area where a coarse grain size is needed thereby remelting the area with fine grain sizes. With such a manufacturing method higher lifetime and operation performances of metallic parts and prototypes can be reached.

    Abstract: In a method of synthesizing magnesium-cobalt pentahydride, a MgCo2 alloy is synthesized by completely reacting cobalt (Co) metal and excess magnesium (Mg) metal, followed by an isothermal evaporation casting process (IECP) for removing the residual magnesium metal. Then, the magnesium-cobalt alloy and another magnesium metal are ball-milled and hydrogenated to synthesize the magnesium-cobalt pentahydride (Mg2CoH5).

  • Publication number: 20110306508
    Abstract: The presence of mycotoxins in agricultural products necessitates large scale testing of a wide range of sample material to ensure the safety of food and feed. The mycotoxin ochratoxin A represents an enablement for all mycotoxins as the level of sensitivity necessary for regulatory requirements for this compound at the part per billion level are as low or lower than any other mycotoxin. This invention describes the identification of a set of DNA ligands with sufficiently high binding affinity and specificity for ochratoxin A to enable an improvement over existing methods for the separation, concentration and quantitative determination of ochratoxin A in sample material.
