    Abstract: A monolithic substrate of glass or glass ceramics and methods for manufacturing are provided, where the substrate has a lightweight structure. The lightweight structure includes recesses that are delimited by webs, such webs forming tetragonal or four-corner-shaped pockets. Due to the lightweight structure, the weight of the substrate can be significantly reduced, and at the same time a high rigidity can be ensured. The substrate can be used as a mirror support or a mirror and can be employed terrestrially and/or extra-terrestrially.

    Abstract: A method is for producing and applying an antiscatter grid or collimator to an x-ray or gamma detector having matricially arranged detector elements which form a detector surface with detection regions sensitive to x-radiation and/or gamma radiation and less sensitive intermediate regions. In the method, a basic structure is firstly produced for the antiscatter grid or collimator by way of a rapid prototyping technique, through which transmission channels and intermediate walls of the antiscatter grid or collimator are formed which have at least in a first direction a center-to-center spacing which is equal to or an integral multiple of a center-to-center spacing of the sensitive detection regions of the detector. The intermediate walls are coated with a material which strongly absorbs x-radiation and/or gamma radiation in order to finish the antiscatter grid or collimator. Subsequently, the antiscatter grid or collimator is applied to the detector surface and connected to the detector surface in such a way that at least the intermediate walls running perpendicular to the first direction, or their coating, are situated over the less sensitive intermediate regions of the detector surface. A detector having an antiscatter grid or collimator in which no moiré interference occurs can thus be realized in a simple way.

    Abstract: Polyolefine-based mouldings and foils contain internal bonding additives which are enriched by migration at the plastic surface and which have their molecular structure bonding substituents of higher polarity on an oleophilic hydrocarbon radical. At least one part of these internal additives is hardened via its hydrocarbon radicals in the area of the plastic surface and prevented from further migrating, and so permanent adhesive bondings and/or coatings of the polyolefine surface may be obtained without additional preliminary treatments. Also disclosed is a process for furnishing solid polyolefine surfaces with such adherence-improving, immobilised additive (mixtures), and other auxiliary agents used for that purpose.

    Abstract: A method is for producing an antiscatter grid or collimator for a radiation type, which is formed from a base body of predeterminable geometry having transmission channels for primary radiation of the radiation type which extend between two opposite surfaces of the base body. In the method, the base body is constructed by use of a rapid prototyping technique by layer-wise solidification of a structural material, which is substantially transmissive to the radiation type, under the action of radiation. Inner surfaces of the base body in the transmission channels are coated with a material, which strongly absorbs the radiation type, up to a layer thickness which suffices to virtually completely absorb incident secondary radiation of the radiation type. The opposite surfaces of the base body are not coated, or are aftertreated in such a way that they do not bear a coating or bear a coating of greatly reduced layer thickness made from the material strongly absorbing the radiation type. The method permits the simple production of an antiscatter grid or collimator with high primary beam transparency.
