  • System and method for suppressing sublimation using opacified aerogel
    Patent number: 7461512
    Abstract: The present invention relates to a castable, aerogel-based, ultra-low thermal conductivity opacified insulation to suppress sublimation. More specifically, the present invention relates to an aerogel opacified with various opacifying or reflecting constituents to suppress sublimation and provide thermal insulation in thermoelectric modules. The opacifying constituent can be graded within the aerogel for increased sublimation suppression, and the density of the aerogel can similarly be graded to achieve optimal thermal insulation and sublimation suppression.
    Type: Grant

  • System and method for fabrication of high-efficiency durable thermoelectric devices
    Publication number: 20060157101
    Abstract: The present invention relates to a durable high-efficiency thermoelectric device. More specifically, the present invention relates to a thermoelectric device formed with a novel thermoelectric material and system which incorporates a vaporizable scaffolding to create microscopic gaps between the thermoelectric elements which are filled with a high-density, shrink-resistant aerogel.
