The invention relates to tuned multifunctional linker molecules for charge transport through organic-inorganic composite structures. A cursor is placed at a location on the document. Said aim is achieved by a binder which is used for materials based on wood chips andor wood fibers, comprises an aldehyde-based condensation resin and other additives, and is characterized in that the binder comprises a water-soluble reactive additive containing a peptideamino acid mixture without moieties of water-insoluble and high-viscosity proteins. At least one manually actuated control for regulating one aspect of operation of the system is mounted to the chin bar.
