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: In one or more embodiments described herein, there is provided an apparatus including a support layer, a plurality of pixels, and a switch. The pixels are formed using an arrangement of respective liquid-phobic elements disposed on the support layer. The arrangement of the liquid-phobic elements is configured so as to be able to provide, when interacting with a liquid on the support layer, one or more associated plastron regions to provide a first pixel optical state. The switch is configured to be able to selectively modify one or more of said associated plastron regions to provide a second pixel optical state.

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.
