摘要:
A thin buffer layer (303) is used to coat on the multi-filament (401) wrapped string to fill the gaps. The polymers of the buffer-layer coating have a high melt-flow (low viscosity) during coating process to fill all the gaps between the filaments, and the filaments are fixed by the coatings onto base core materials.

An article of manufacture comprises a carbon-containing matrix. The carbon- containing matrix may comprise at least one type of carbon material selected from the group comprising graphite crystalline carbon materials, carbon powder, and artificial graphite powder. In addition, the carbon-containing matrix comprises a plurality of pores. The article of manufacture also comprises a metal component comprising Al, alloys of Al, or combinations thereof. The metal component is disposed in at least a portion of the plurality of pores. Further, the article of manufacture comprises an additive comprising at least Si. At least a portion of the additive is disposed in an interface between the metal component within the pores and the carbon-containing matrix. The additive enhances phonon coupling and propagation at the interface.
摘要:
A high voltage driver (101) with capacitive (106) coupling that is useful in the presence of the high power supply ripple common with higher-voltage systems (118). It permits extreme ranges of duty cycle, but without the limitations of transformer magnetics, or the increased complexity of optical coupling methods. It is also robust in the presence of voltage transients created by high-voltage arcing to the output (105) drive-line.
摘要:
A metallic composition including a solvent and a plurality of metal nanoparticles dispersed therein is formulated such that curing of the metallic composition on a substrate provides a metallic conductor with a resistivity of about 5 x 10 -4 Ωcm or less. Electrical components of an assembly can be interconnected by a metallic conductor formed by curing the metallic composition on a substrate. A metallic composition including metal nanoparticles can be deposited on a substrate and solidified. The metallic composition can be contacted with a metal wire before or after solidification of the metallic composition and secured to the solidified metallic composition.
