摘要:
A thermoelectric power generation device using molybdenum metallization to a Zintl thermoelectric material in a thermoelectric power generation device operating at high temperature, e.g. at or above 1000° C., is disclosed. The Zintl thermoelectric material may comprise Yb14MnSb11. A thin molybdenum metallization layer of approximately 5 microns or less may be employed. The thin molybdenum layer may be applied in a foil under high pressure, e.g. 1800 psi, at high temperature, e.g. 1000° C. The metallization layer may then be bonded or brazed to other components, such as heat collectors or current carrying electrodes, of the thermoelectric power generation device.
摘要:
A method of making colloidal sphere templates and the sphere-templated porous materials made from the templates. The templated porous materials or thin films comprise micron and submicron-scaled spheres in ordered, disordered, or partially ordered arrays. The invention is useful in the synthesis of submicron porous, metallic tin-based and other high capacity anode materials with controlled pore structures for application in rechargeable lithium-ion batteries. The expected benefits of the resulting nanostructured metal films include a large increase in lithium storage capacity, rate capability, and improved stability with electrochemical cycling.
摘要:
Millimeter to nano-scale structures manufactured using a multi-component polymer fiber matrix are disclosed. The use of dissimilar polymers allows the selective dissolution of the polymers at various stages of the manufacturing process. In one application, biocompatible matrixes may be formed with long pore length and small pore size. The manufacturing process begins with a first polymer fiber arranged in a matrix formed by a second polymer fiber. End caps may be attached to provide structural support and the polymer fiber matrix selectively dissolved away leaving only the long polymer fibers. These may be exposed to another product, such as a biocompatible gel to form a biocompatible matrix. The polymer fibers may then be selectively dissolved leaving only a biocompatible gel scaffold with the pores formed by the dissolved polymer fibers.

摘要:
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.
