    摘要: The chip stack of semiconductor chips with enhanced cooling apparatus includes a first chip with circuitry on a first side and a second chip electrically and mechanically coupled to the first chip by a grid of connectors. The chip stack further includes a thermal interface material pad between the first chip and the second chip. The thermal interface material pad comprises a plurality of nanotubes containing a magnetic material, aligned parallel to mating surfaces of the first chip and the second chip, wherein a hydrophobic tail of oleic acid is wrapped around each one of the plurality of nanotubes and a hydrophilic acid head of the oleic acid is attached to the magnetic material.

    摘要: Techniques for preparing PNCs are provided. In one embodiment, a polymer extruding device may include a barrel configured to accommodate a composite material, a shaft rotatably disposed in the barrel, and a motor coupled to the shaft and configured to rotate the shaft, thereby moving the composite material. The polymer extruding device may further include a die including one or more injectors configured to inject nano particles into the die to cause shear stress to be exerted to the composite material, thereby forming a layer of the nano particles on a surface of the composite material.

    摘要: Magnetostrictive particulate composites with a preferred crystal orientation of the particles and methods for their manufacture are described. In a representative embodiment, a 25% volume Terfenol-D fraction polymer matrix composite was fabricated in a magnetic field using geometric anisotropy to orient needle shaped particles with long axis [112] orientation along the length of the composite. Results demonstrate that the magnetostriction of a [112] oriented particle composite saturates near 1600 ppm. This is a significant increase when compared to composites without preferential orientation (1200 ppm) and represents the largest reported magnetostriction for a particulate composite material.
