The invention relates to an organic light-emitting diode (OLED) having an improved lifetime and improved transport of negative charge carriers. The organic light-emitting diode is based on an organic semiconductor material, in which the transport of negative charge carriers and stability with respect to reduction is achieved with triarylated Lewis acid units, in particular perarylated borane units. This leads to an improved lifetime of the emission layer which in turn increases the lifetime of the component and eliminates the need for correcting brightness during operation. Furthermore, the invention relates to organic light-emitting diodes in which the position of the emission zone in the emitter layer and the color of the emission can be influenced in a targeted manner through triarylated Lewis acids such as perarylated borane units.

A method of encapsulating components based on organic semiconductors, includes adhesively bonding a housing to a substrate. Bonding is carried out using a UV-curable reactive adhesive including an epoxy resin, a hydroxy-functional reaction product of an epoxide compound with a phenolic compound, a silane-type adhesion promoter, and a photoinitiator, and also if desired, filler. This method is used in particular for encapsulating organic light-emitting diodes (OLEDs).

A corona shielding band having reproducible qualities and allowing only a small increase in dielectric losses in a winding of an insulation of electrical machine is made by impregnating a woven-type support material with an active resin solution containing an inorganic filler with a coating composed of antimony-doped tin oxide and then removing the solvent by a thermal processing to produce the corona shielding band.

In a rotating electrical machine having a permanent-magnet rotor, the tubular, highly thermally conductive supporting body of the stator forms a thermal bridge to a cooling means. In order to allow the end windings of the stator windings to be cooled effectively as well, the end windings also each have an associated thermal bridge, which completely fills the space between the end windings and the supporting body of the stator. This thermal bridge is of solid construction having a solid ring, which is connected to the supporting body of the stator with a force fit, and a cast-resin body which is cast into this solid ring. The cast-resin body has a thermal conductivity of more than 1.6 W/mK and, for this purpose, contains a powdery, highly thermally conductive filler making up a proportion of 50 to 90% by weight, preferably an aluminum nitride coated with silicon dioxide.
