Abstract: The invention relates to a method for producing a biodegradable molded part, comprising: providing a binding agent which contains a lyzable biopolymer; forming a molded part from the binding agent, wherein the time stability of the molded part to biological lysis is set by at least one of the following measures: adding a pulverized inorganic solid matter in a proportion of 5% to 85% of the mass of the binding agent before forming the molded part; thawing at least one of the surfaces of the molded part using a chemical or biological method such that the surface has a structuring in the range between 1 nm and 10 ?m. The invention further relates to an accordingly produced molded part.

Abstract: The invention relates to a redox battery comprising a proton-permeable membrane, a first electrolyte (5) and a second electrolyte (6), as well as a first electrode (7) and a second electrode (8). The membrane is designed as a hollow profiled member (4), the electrolytes (5, 6) are provided in a liquid form at least in the operating state, the first electrolyte (5) and the first electrode (7) are disposed inside the hollow profiled member (4), the second electrolyte (6) is externally arranged around the hollow profiled member (4), and the second electrode (8) is externally placed on or near the hollow profiled member (4). Furthermore, a plurality of electrodes (7 or 8) are connected in parallel, and the interior spaces of the hollow profiled members (4) are fluidically interconnected.

Abstract: The invention relates to a fiber assembly (1) comprised of at least two fibers (2, 3), in which at least one first fiber (3), with a laterally open hollow profile, at least partially surrounds a second fiber (2) formed separately from the first fiber, and accommodates, inside its cavity, the second fiber while coming in contact with the second fiber.

Abstract: The invention relates to a bionic organ replacement which has a structure consisting of three groups of textile hollow microfibers. The hollow microfibers of each group run into in a liquid conductor which is central respectively. The hollow microfibers of the first group (1) are made from a proton-conducting material and have perforations (2) for draining bile into the area inside the fibers (1). One of the surfaces in essentially every hollow microfiber (1) of the first group (1) is hydrophilic and lipophilic whilst the other surface is hydrophobic and lipophobic. Cell cultures can be grown on the outer surfaces of all of the hollow microfibers.

Abstract: The invention relates to a method for producing ceramic fibers from a molten mass. In accordance with this method, a molten mass of ceramic starting materials, at a temperature of at least approx. 1150° C., is passed through the nozzle of a tool, and then left to solidify. At least the parts of the tool which are subjected to the effect of the molten mass are made of a material having a melting point of over approximately 2200° C., as well as the necessary consistency and corrosion resistance. The invention also relates to the ceramic fibers produced by this method, in particular hollow microfibers, preferably in monolithic form, and their use.

Abstract: The present invention is directed to a process and apparatus for producing synthesis gas by electrolysis. The process for producing synthetic gas is heat exchanged between reactants and reaction products of at least one reaction product carried out using textile micro-hollow fibers having non-activated surfaces as heat exchangers as solid electrolytes, the inside and outside surfaces which carry the anodes and cathodes, respectively. The apparatus for producing synthesis gas by electrolysis comprises a multitude of stacked textiles micro-hollow fibers as solid electrolytes, the inside and outside surfaces of which carry the anodes and cathodes, respectively, wherein the ends of the micro-hollow fibers are bound into a frame, and a pressure housing accommodating the stacks is made from a ferromagnetic material and has a partly enameled surface.
