Abstract: This invention concerns a biomimetic material based on energy-rich amorphous magnesium polyphosphate (Mg-polyP) microparticles that enhance cartilage synthesis and regeneration. One preferred formulation of the inventive material is a hyaluronic acid-Mg/Ca-polyP paste that can be produced from a water-soluble salt of polyP and water-soluble hyaluronic acid in the presence of water-insoluble/nearly insoluble calcium carbonate. Surprisingly, the inventor found that this cartilage-like material comprising amorphous Mg/Ca-polyP microparticles promotes the adhesion of chondrocytes and strongly upregulates the expression of the chondrocyte marker genes encoding alkaline phosphatase, collagen type 3A1, aggrecan and Sox9.

Abstract: This invention relates to a method for sealing dentinal tubules exposed at the tooth surface as a consequence of enamel defects, based on amorphous calcium polyphosphate (Ca-polyP) nano- or microparticles that strongly bind both to tooth enamel, cementum and dentin surfaces. The inventive method can also be used for the production of morphogenetically active tooth implants. A further aspect of this invention concerns the incorporation of such nano- or microparticles, after encapsulation of retinol (“retinol/aCa-polyP nano- or microspheres”), into wound dressings and related materials that are made, e.g., by electrospinning. The resulting, inventive retinol/aCa-polyP nano- or microspheres fiber mats show antimicrobial and wound healing properties and was found to increase the expression of the genes encoding for leptin and the leptin receptor, as well as the fatty acid binding protein 4 (FABP4) in a synergistic manner.

In a preferred aspect, the invention concerns a method for producing amorphous retinol/calcium-polyphosphate nanospheres (retinol/aCa-polyP-NS) that show several unexpected properties and can be used in the treatment or prophylaxis of a variety of dermatological conditions, including photoaging.

Abstract: It is proposed to use a spun birefringent fiber for a current sensor or magnetic field sensor. The fiber has a birefringence that increases with temperature. In this case, the temperature dependence of the fiber's sensitivity to magnetic fields counteracts the temperature dependence of the fiber's Verdet constant, which allows to design current and field sensors that have reduced temperature dependence.

Abstract: A fiber optic sensor and related method are described, with the sensor including a cross-coupling element in the optical path between a polarizing element and a sensing element, but separated from the sensing element itself; with the cross-coupling element generating a defined cross-coupling between the two orthogonal polarization states of the fundamental mode of a polarization maintaining fiber guiding light from the light source to the sensing element thus introducing a wavelength-dependent or temperature-dependent sensor signal shift to balance wavelength-dependent or temperature-dependent signal shifts due to other elements of the sensor, particularly signal shifts due to the wavelength dependence of the Faraday effect or the electro-optic effect constant.

Abstract: A method of increasing accuracy of optical sensors based on generating two sets of light waves having different velocities in the presence of a non-vanishing measurand field within a sensing element of the sensor is described. A defined static bias phase shift is introduced between the two sets of light waves. The sensor converts a total optical phase shift including static bias optical phase shifts and measurand-induced optical phase shifts into anti-phase optical power changes in at least two detector channels. The method includes steps of normalizing the optical power changes after their conversion into electrical detector signals in the two detector channels to reduce effects of uneven intensity or power of the light source and different loss or gain in the detector channels. Further methods, sensors and apparatus for temperature stabilizing such optical sensors and novel sensors are also presented.

Abstract: The present invention relates to a method for the production of crystal layers or bulk crystals of group III nitride or of mixtures of different group III nitrides by means of precipitation, at a first temperature T1 in a first temperature range, from a group-III containing fused metal on a group-III-nitride crystal seed placed in the fused metal or on a foreign substrate placed in the fused metal, with the admixture of nitrogen in the fused metal at a pressure P.
