Abstract: A method includes applying a filler material to at least one component, the filler material including a heat curable matrix and nanoparticles; and applying an electromagnetic field to at least part of the filler material. The nanoparticles have a core capable of being heated by the electromagnetic field to a temperature sufficient to at least partially cure surrounding matrix. Another method involves applying a filler material to at least one component, the filler material including a matrix containing nanoparticles. The nanoparticles have a magnetic property and are present in a concentration sufficient to cause the matrix to flow in response to application of a magnetic field. The method also includes generating a magnetic field so as to guide the matrix into a space to be filled.

Abstract: A device based on iontophoresis and intended for transdermal dosing of an active agent, said device comprising a pair of electrodes (11,12), which can be connected to a direct-current source, and two chambers (13, 14), separated from each other, the first chamber (13) containing the active agent, each chamber having a porous membrane (15, 16) on the side facing the individual's skin, and the first chamber (13) being divided in two sections (13a, 13b) in such a manner that the first chamber section (13a) is in contact with the electrode (11) and the second chamber section (13b) is in contact with the membrane (15) coming into contact with an individual's skin, wherein between the chamber sections (13a and 13b) is a membrane (18) selectively permeable either to cations or to anions, the first chamber section (13a) containing an electrolyte and the second chamber section (13b) containing the ionic active agent, bound to a ion exchanger therein, which in turn preferably comprises fibres and ion exchanging grou

Abstract: A material contains a curable liquid polymer containing suspended nanoparticles capable of exhibiting a magnetic property. The nanoparticles are present in a concentration sufficient to cause the curable liquid polymer to flow in response to application of a magnetic field, enabling the material to be guided into narrow regions to completely fill such regions prior to the polymer being cured. A method includes applying a filler material to at least one component, the filler material including a heat curable polymer containing nanoparticles, and applying an electromagnetic field to at least part of the filler material. The nanoparticles contain a core capable of experiencing localized heating sufficient to at least partially cure surrounding polymer. Also disclosed is an assembly for use at radio frequencies. The assembly includes a substrate and at least one component supported by the substrate.
