摘要： Composites comprising at least one hollow fiber of oxygen-transporting ceramic material, which is a ceramic material which conducts oxygen anions and electrons or a combination of ceramic material which conducts oxygen anions and a ceramic or nonceramic material which conducts electrons, with the outer surface of the hollow fiber being in contact with the outer surface of the same hollow fiber or another hollow fiber and the contact points being joined by sintering, are described. Further composites comprise at least one hollow fiber of oxygen-transporting ceramic material which is a ceramic material which conducts oxygen anions and electrons or a combination of ceramic material which conducts oxygen anions and ceramic or nonceramic material which conducts electrons and a connection element for the introduction or discharge of fluids at at least one end face, with hollow fibers and connection element being joined. The composites can be used for isolating oxygen from oxygen-containing gas mixtures or for carrying out oxidation reactions.

摘要： The present invention provides the use of a hollow particulate glass as a support for an active agent, characterised in that said hollow particulate glass is produced by pyrolysis of glass-coated polymer particles which are produced by copolymerising an unsaturated heterocyclic monomer and squaric acid, wherein said polymer has the structure: where each R, which may be the same or different, is hydrogen or optionally substituted alkyl; the ring nitrogen atom of the heterocyclic ring is unsubstituted or alkyl (especially methyl) substituted; X is a bond or a bridging group (preferably a bond); y is zero or a positive integer (preferably zero); and z is a positive integer the value whereof determines the molecular weight of the polymer.

摘要： The invention relates to a dark, flat element, preferably a plastic, lacquer coating or fiber material, having reduced density, low heat conductivity and low solar absorption. The flat element has a relatively high reflection infrared range of the electromagnetic spectrum reduce heating by sunlight in the near infrared dark tinting in the visible range. Low density conductivity are obtained inter alia by inserting in the near in order to area despite and low heat light filling materials into the flat element. Said flat element can be used in places where surfaces are dark tinted for aesthetic or technical reasons but should not heat up in sunlight and should give off little heat when touched by hand or by other parts of the body. Other areas of application include surfaces which should have a heat insulating effect in addition to the above-mentioned characteristics.
