In some embodiments, a stamp with metallic elements, may comprise at least one stamping component and one stamping insert. The stamping component may be formed of a top part with a handle element and a bottom part with a cushion-receiving element. The stamping insert may be connected so as to move synchronously via a reversing mechanism having a slide track in the bottom part via a shaft or trunnion to the top part. In the resting position a text plate mounted on the stamping insert may abut against an ink pad soaked with ink in the cushion-receiving element. The metallic elements can be attached from the outside onto the top and bottom parts formed from plastic material and these are fixed via a fastening system of the upper and lower parts. The metal part of the bottom part is fixed on a surface of the plastic part.

A method is provided for extending the frequency band of an audio signal during a decoding or improvement process. The method includes obtaining the decoded signal in a first frequency band, referred to as a low band. Tonal components and a surround signal are extracted from the signal from the low-band signal, and the tonal components and the surround signal are combined by adaptive mixing using energy-level control factors to obtain an audio signal, referred to as a combined signal. The low-band decoded signal before the extraction step or the combined signal after the combination step are extended over at least one second frequency band which is higher than the first frequency band. Also proved are a frequency-band extension device which implements the described method and a decoder including a device of this type.

Methods of printing nanoparticulate ink using nanoporous print stamps are disclosed. A nanoporous print stamp can include a substrate, a patterned arrangement of carbon nanotubes disposed on the substrate, and a secondary material disposed on the carbon nanotubes to reduce capillary-induced deformation of the patterned arrangement of carbon nanotubes when printing nanoparticulate ink. Some methods include loading a nanoporous print stamp with nanoparticulate colloidal ink such that the nanoparticulate colloidal ink is drawn into microstructures of the patterned arrangement of carbon nanotubes via capillary wicking. Nanoparticulate colloidal ink can include nanoparticles dispersed in a solution. The method also includes contacting a nanoporous stamp to a target substrate to form nanoscale contact points between the target substrate and the patterned arrangement of carbon nanotubes of the nanoporous print stamp so that nanoparticulate colloidal ink is drawn out of the nanoporous print stamp and onto the target substrate to form a pattern.
