Abstract: According to the inventive method for producing a superconductive coil, a shaped body consisting of a material which is superconductive or which becomes superconductive upon subsequent heat treatment is coated with reinforcement agents and is given the geometric shape of the future coil. The invention also relates to a superconductive coil produced according to this method. Said inventive superconductive coil has low alternating current loss and consists of a highly textured superconductive material, and is oriented in such a way that the platelet levels are directly considerably in the direction of the course of the coil. The coil is formed from a superconductive solid part.

Abstract: In a monostable ferroelectric active matrix display comprising a liquid-crystal layer in the form of a monodomain having an unambiguously defined direction of the layer normal z of the smC* phase, the layer normals z and the preferential direction n of the nematic or cholesteric phase (N* phase) form an angle of more than 5°.

Abstract: A process for preparing a 1-aryl-4-(arylethyl)piperazine of the formula (I) by reacting a 1-arylpiperazine of the formula (II) with an aromatic olefin of the formula (III) Ar′CR1═CHR2  (III) in an inert solvent in the presence of at least one basic catalyst, where in the formulae (I) to (III) Ar and Ar′ independently of one another are an aryl radical, selected from the group of the fused and unfused C6-C22-aromatics and the fused or unfused C5-C22-heteroaromatics which have at least one nitrogen, oxygen or sulfur atom in the ring; and R1 and R2 independently of one another are a hydrogen atom, a C1-C8-alkyl radical or an aryl radical Ar.
