Abstract: The present invention relates to elastomer toothed belts comprising a fabric spanning the teeth of the toothed belt, wherein the elastomer mixture forming the teeth contains a crosslinked ethylene-propylene rubber (EPM) and/or a crosslinked ethylene-propylene terpolymer rubber (EPDM) accounting for at least 70% by weight of the elastomer mixture based on the polymer proportion and wherein an interlayer is arranged between the fabric and the elastomer mixture forming the teeth which contains at least 70% by weight of hydrogenated acrylonitrile-butadiene rubber (HNBR) based on the polymer proportion of the interlayer. Such elastomer toothed belts are halogen-free and feature improved durability and good low-temperature stability properties.

Abstract: The invention relates to a drive belt (1) having a main body into which one or more tension strands (3) composed of para-aramid in cord construction are embedded, wherein each tension strand (3) has twisted plies each formed from at least one twisted yarn, and wherein the turning direction of the respective ply (first twist) is the opposite of the turning direction of the cord (final twist). It is a feature of the invention that the tension strands (3) each have at least four plies, wherein the twist factor TM1 of the plies (first twist) is between 4.5 and 5.4, and the twist factor TM2 of the cord (final twist) is between 2.7 and 3.8, and the ratio of the twist factor of the plies to the twist factor of the cord (TM1/TM2) is between 1.3 and 1.5.

Abstract: A method of producing a microarray, the microarray itself and the use of the microarray for detecting interactions between probe molecules and analyte molecules from a sample is provided. The method comprises the steps of synthesis, in two or more stages, of probe molecules on a polymeric support, bonds being formed between the probe molecules and the polymeric support; dispersion of the polymeric support having the synthetic probe molecules, the bonds between the polymeric support and the probe molecules being retained; optional purification of the probe molecules bound to the polymeric support; dissolution of the polymeric support having the bound probe molecules; and application of the solution containing the polymeric support having the bound probe molecules in the form of microdrops to a planar surface.
