Abstract: The present invention provides a new class of organic/inorganic hybrid materials having [ER]n rings interconnected by E? atoms. In an embodiment a class of materials called high organic group content periodic mesoporous organosilicas (HO-PMO's) with [SiR]3 rings interconnected by O atoms is described. The measured dielectric, mechanical and thermal properties of the materials suggest that an increased organic content achieved by the [SiR]3 rings of a high organic group content periodic mesoporous organosilica leads to superior materials properties potentially useful for a wide range of applications including microelectronics, separation, catalysis, sensing, optics or electronic printing.

Abstract: This invention relates to a chemical transformation of the bridging organic groups in metal oxide materials containing bridging organic groups, such as bridged organosilicas, wherein such a transformation greatly benefits properties for low dielectric constant (k) applications. A thermal treatment at specific temperatures is shown to cause a transformation of the organic groups from a bridging to a terminal configuration, which consumes polar hydroxyl groups. The transformation causes k to decrease, and the hydrophobicity to increase (through ‘self-hydrophobization’). As a result of the bridge-terminal transformation, porous organosilica films are shown to have k<2.0, E>6 GPa, do not require additional chemical surface treatment for dehydroxylation (hydrophobicity).

Abstract: A process and an apparatus for removal of a lumen filler and/or other soluble residues from hollow filament bundles are described. The hollow filament bundles are first roughly cleaned by centrifuging, after which in a process preferably containing multiple steps they are cleaned by spraying and centrifuging. The first spraying step is preferably carried out in a pass-through mode and each of the additional steps under recirculation. After a constant concentration has been attained, the cleaning baths in each case are employed for a lower-order treatment step, the cleaning bath of the first spraying step being fed to a recycling process.

Abstract: A bundle of hollow fibers of uniform diameter, particularly for use in dialysis is formed of a plurality of parallel hollow fibres at least a part of which, prior to the formation of the bundle, is permanently undulated by means of interleaved undulating elements moving opposite the feeding direction of freshly extruded fibres. The undulating elements are in the form of cylindrical rods having a substantially larger diameter than the outer diameter of the fibres so that the wavelength and amplitude of the resulting undulations are substantially larger than the outer diameter of the fibres.

Abstract: Hollow fiber bundle of hollow fibers arranged in layers on top of one another and fiber layers arranged between the hollow fiber layers, in which, in a top view looking down on the hollow fiber bundle, the hollow fibers are formed so that they are undulating or essentially rectilinear and the fibers are undulating, and so formed and/or arranged that the hollow fibers and the fibers intersect at several locations.

Abstract: Disclosed is a method of and a device for producing bundles of hollow fibers such as used for dialysis. The device includes a guiding device for a continuous fiber which rotates in a plane. At least two groups of take-up elements are mounted on a conveyor. The conveyor is intermittently activated so that a group of take-up elements is placed in a working position in the range of movement of the guiding device, and a strand of a desired thickness is wound around the take-up elements. Thereafter, the conveyor is activated to discharge the first group together with the completed strand from the working position and place the subsequent empty group of take-up elements in the working position, without interruption of movement of the guiding device. During the winding-up of the subsequent strand, the completed strand is cut and wrapped into bundles.

The hollow thread bundle can be produced by wrapping the plurality of hollow threads by a sewing seam including at least one sewing thread.

Abstract: 1,4-Naphthoquinone is prepared by reacting naphthalene with molecular oxygen in a gaseous phase in the presence of a catalyst containing vanadium. Prior to reacting the naphthalene with oxygen, the catalyst is pre-treated with molecular oxygen at 300.degree. to 400.degree.

C. The catalyst pre-treatment can be carried out in the presence of water vapor and the subsequent reaction of naphthalene with molecular oxygen can also be carried out in the presence of water vapor.
