Abstract: A composite multi-layer textile, comprising at least one nanofibre layer with nanofibres with diameters below 100 nm and one support layer with microfibres with diameters below three microns, wherein the layers were produced by electrospinning. The multi-layer textile shows a general transmittance at #=550 nm greater than 60%, which shows improved properties concerning transparency, breathability and robustness. This is achieved in that the at least one nanofibre layer and the support layer are fused, forming solid domains in the multi-layer textile, at closed areas of a pattern used in the production process, wherein the solid domains are separated from each other or connected, showing defined shapes, with regular or irregular spatial distribution, while the fibre morphology of nanofibres of the nanofibre layer and microfibres of support layer is preserved on top of the open areas beside the solid domains, attaining a general transmittance greater than that given by the sum of the individual layers.

Abstract: The present invention exploits reactive organophosphorus compounds containing unsaturated vinyl groups, which can be used in a flexible and highly controlled manner to prepare various macromolecular derivatives either via radical reactions or via Michael addition with suitable nucleophiles. Based on the fact that secondary amine groups on the one hand and vinyl groups on the other hand can work as mutual linking sites, an arsenal of novel and useful addition products can be built up. By selecting the number of secondary amine sites and vinyl sites of the participating reaction partners, very different addition products can be formed. In particular, one can form either linear chain type macromolecules (i.e. linear oligomers or polymers) or highly crosslinked network polymers.

Abstract: A waveguide spectrometer includes at least one substrate layer with at least one waveguide. Each waveguide extends from an inlet face proceeding partly through the substrate layer to a reflecting element. A multiplicity of photo detectors is arranged on a front side of the substrate layer, while the photo detectors are electrically connected to an electronic read out system.

The photo detectors are in print distributed at the front side on top of the substrate layer at least partly overlapping the longitudinal opening along an overall length of sampled region and the electrical connection of the photo detectors with the electronic read out system is achieved by a multiplicity of printed electrical conductors.

Abstract: A unit cell of an artificial phononic crystal for building of an artificial phononic metamaterial, showing reduced mechanical vibrations in a defined frequency range with at least one band gap in the band structure dispersion relation of the unit cell. The unit cell includes at least one building block and at least one mechanical connection connected to the building block, showing reduced mechanical vibrations in a defined frequency range with tailored dispersion properties with at least one band gap is sought. This is accomplished by forming the building block as a toroid, with a central opening and a front surface from which a first multiplicity of struts, which are tiltable relatively to the principal direction, is extending from the front surface. More than one strut is inclined with respect to the principal direction so that a rotation of the toroid around the principal direction is possible.

Abstract: The method includes a tension element, for example in the form of flat steel, that is placed on the structure or structural part and can be guided around a corner. The flat steel can also wrap as a band around the structure, in which the two ends of the flat steel are either connected to one another or are separately connected to the structure by the end anchors or intersect to produce a clamping connection. The flat steel contracts as a result of a subsequent active and controlled input of heat using a heating element and generates a permanent tensile stress and, correspondingly, a permanent prestress on the structure. The structure, as equipped, has at least one tension element as a shape memory alloy which extends along the outer side of the structure and is connected by one or more end anchors.

Abstract: In a method for improving the acoustic properties of spruce resonance wood for musical instruments at least one resonance wood blank is subjected to a treatment with Physisporinus vitreus under controlled, sterile conditions. The previously sterilized resonance wood blank is immersed into a liquid medium enriched with fungus myecelium and kept therein in the dark for an exposure time and finally sterilized, wherein during the exposure time a temperature of 18 to 26° C. and a relative humidity of approximately 60 to approximately 80% are maintained. Due to the fact that the liquid medium contains nanofibrillated cellulose (NFC) in an amount of 200 to 300 g per liter, a reproducible, uniform improvement of the acoustic properties of the resonance wood free from local defects is ensured.
