Abstract: A bimodal metal nanocomposite of ceramic nanoparticles in a metal or metal alloy matrix has a microstructure showing a first “hard” phase containing the ceramic nanoparticles in the metal or metal alloy matrix, and a second “soft” phase comprising only the metal or metal alloy with few or no ceramic nanoparticles. The stiffness and yield strength of the bimodal metal nanocomposite is significantly increased compared to the metal or metal alloy alone, while the ductility of the metal or metal alloy is retained. A process for making the bimodal metal matrix nanocomposite includes milling a powder mixture of micrometer-size metal flakes and ceramic nanoparticles for a time sufficient to embed the ceramic nanoparticles into the metal flakes.

Abstract: A resonator for sensing a physical or an environmental parameter includes a support having a top surface that provides a ground plane, and a polymer-derived ceramic (PDC) element positioned on the top surface including a PDC layer, and a metal patch on the PDC layer. The metal patch is electrically isolated from all surrounding structure, and the resonator has a resonant frequency that changes as a function of the physical or environmental parameter. A system for wirelessly sensing a physical or environmental parameter includes at least one resonator and a wireless RF reader located remotely from the resonator for transmitting a wide-band RF interrogation signal that excites the resonator. The wireless RF reader detects a sensing signal retransmitted by the resonator and includes a processor for determining the physical or environmental parameter at the location of the resonator from the sensing signal.
