  • Patent number: 9005483
    Abstract: Nanoparticle paste formulations can be configured to maintain a fluid state, promote dispensation, and mitigate crack formation during nanoparticle fusion. Such nanoparticle paste formulations can contain an organic matrix and a plurality of metal nanoparticles dispersed in the organic matrix, where the plurality of metal nanoparticles constitute about 30% to about 90% of the nanoparticle paste formulation by weight. The nanoparticle paste formulations can maintain a fluid state and be dispensable through a micron-size aperture. The organic matrix can contain one or more organic solvents, such as the combination of one or more hydrocarbons, one or more alcohols, one or more amines, and one or more organic acids. Optionally, the nanoparticle paste formulations can contain about 0.01 to about 15 percent by weight micron-scale metal particles or other additives.

  • Publication number: 20140374079
    Abstract: Materials that readily adhere to and conform to various surfaces can be desirable for a number of applications. In heat transfer and thermal management applications, for example, conformable materials can be used in establishing a thermal interface between a heat source and a heat sink. There are limited materials that provide good thermal conductivity values while maintaining capabilities to readily adhere and conform to a surface. Compositions including a conformable and adhesive solid can include a reaction product formed by heating a mixture containing a plurality of metal nanoparticles, one or more amines, and one or more carboxylic acids. The compositions can further include one or more additives dispersed in the conformable and adhesive solid.

  • Patent number: 8525600
    Abstract: A protective assembly that is adapted to provide temperature isolation for an electronic device is disclosed. The assembly includes a housing having a cavity with a top surface and at least one side surface. The housing is configured to accept an electronic device having a top and a bottom in the cavity with the top of the electronic device proximate to the top surface of the cavity. The housing is further configured to maintain a vacuum within the cavity. The assembly includes at least one support disposed within the cavity. The at least one support is configured to contact the housing only at a first point proximate to the top surface of the cavity and contact the electronic device only at a second point that is proximate to the bottom of the electronic device.
