Abstract: An electric machine for a motor vehicle, includes a rotor, and a stator. The stator has a coil device for generating a magnetic rotary field for driving the rotor. the coil device has a soft magnetic flux-guiding device for guiding the rotary field, wherein the coil device is only partially arranged in the flux-guiding device, wherein at least one winding overhang of the coil device extends out of the flux guiding device into an environment of the stator. The electric also includes and an electrically conductive shielding element arranged on the at least one winding overhang and configured to electrically and/or electromagnetically shield the winding overhang against an environment, wherein the shielding element is connected to a frame potential connection of the electric machine.

Abstract: A method is provided to synthesize nanocomposites containing intercalated FeF2— or Fe2O3— nanoparticles in a graphitic carbon matrix by reaction of a volatile iron compound with a graphite fluoride (CFx) or a graphite oxide (COx). Additionally provided is a nanocomposite material containing intercalated FeF2— or Fe2O3— nanoparticles in a graphitic carbon matrix and its use as an electrochemically active material in particular for use in electrochemical storage cells.

Abstract: A method for making optical connections with optical waveguides includes mounting the optical waveguides or a device comprising the optical waveguides, on a component carrier. A partial region of the optical waveguides is embedded in a volume of resist material. Positions of the optical waveguides to be connected are detected with reference to a coordinate system using a measuring system. Favorable, three-dimensional geometries are determined for optical waveguide structures for connecting the optical waveguides to each other at predetermined connecting locations and the optical waveguide structure geometries are converted to a machine-readable dataset. The optical waveguide geometries in the volume of the resist material are three-dimensionally structured using a direct-writing lithography device operating on the basis of the machine-readable dataset.

Abstract: An arrangement and method for generating or depositing a stream of m>1 fluid segments, respectively separated by an intermediary medium which does not mix with the fluid segments. The arrangement includes a molded body having a channel for conducting the fluid stream, from which n?m first access lines and n second access lines branch off. The first and second access lines are configured so to be inserted into n wells. The lengths of the first access lines differ from the lengths of the second access lines, and respectively one first valve is arranged in the channel, between the branching location for each second access line and the branching location for each associated first access line, and wherein respectively a second valve is arranged in each second access line.

Abstract: An apparatus for storing hydrogen and magnetic energy includes a storage tank for liquefied hydrogen with an inlet line for compressed hydrogen and an outlet line for hydrogen at a relatively low pressure. The apparatus includes a superconducting magnetic energy store, which comprises a magnetic coil relative to which electrical energy can be supplied or withdrawn via power supply lines to the magnet coil, the energy being located in a cryogenic tank provided with a cooling device and being held at operating temperature. The storage tank for liquefied hydrogen includes cooling device, at least one regenerator, with a heat-absorbing and heat-emitting storage medium, a warm side and a cold side. From the warm side, the compressed hydrogen and, from the cold side, liquefied hydrogen can be supplied from the storage tank for liquefied hydrogen. A relief valve is located in the field region of the at least one magnet coil.
