Abstract: A device for converting biomass with a water content of at least 50% to gaseous products includes a reactor filled at least partially with a packing including at least one filler body for accommodating supercritical water and a hydrothermal molten salt. A heater is arranged to heat up the reactor and its content. A first feeding pipe is coupled to the reactor to feed water and salt solution into the reactor. A second feeding pipe is coupled to the reactor to feed to biomass into the reactor. A discharge pipe is coupled to the reactor to discharge gaseous products from the reactor. An outlet is proved in the bottom of the reactor for removing portions of the molten salt.

Abstract: A fiber-reinforced mineral building material includes at least one fiber, which is embedded into the mineral building material, at least one ductile or elastic coating on the fiber, and particles that are material-bonded with the coating. The dimensions of the particles on the greater share of the surface area exceed the thickness of the coating and the particles in part project material-bonded into the mineral building material.

Abstract: An optical arrangement includes a plurality of planar substrates with at least one planar integrated optical waveguide on each planar substrate. At least one optical waveguide structure has at least one end connected via an optical connecting structure to one of the planar integrated optical waveguides. The optical waveguide structure is positioned at least partly outside the integration plane for the planar integrated optical waveguide and a refractive index contrast between a core region and a cladding region of the optical waveguide structure is at least 0.01.

Abstract: Nuclear magnetic resonance in a sample volume located in a measuring volume is examined by generating a packet of laser pulses to act on the measuring volume when a quasi-static magnetic field occurs therein. If the resonance conditions for nuclear spins contained therein are fulfilled, the sample volume emits a response signal that is received by a detector. The quasi-static magnetic field occurring within the measuring volume is generated by acting on the measuring volume with a low-frequency laser beam having a wavelength that exceeds the wavelength of the excitation laser by at least 102 to create a periodically variable magnetic field in the measuring volume. The amplitude of the field is at least 90% of the maximum thereof in the measuring volume. Alternatively, the measuring volume is acted on by a high-frequency laser beam having a frequency exceeding the frequency of the excitation laser by at least 102.
