20120138873 | SINTERING PROCESS FOR THERMOELECTRIC MATERIALS - A process for densifying a composite material is provided. In some instances, the process can reduce stress in a sintered component such that improved densification and/or properties of the component is provided. The process includes providing a mixture of a first material particles and second material particles, pre-sintering the mixture at a first pressure and a first temperature in order to form a pre-sintered component, and then crushing, grinding, and sieving the pre-sintered component in order to form or obtain a generally uniform composite powder. The uniform composite powder is then sintered at a second pressure and a second temperature to form a sintered component, the second pressure being greater than the second pressure. | 06-07-2012 |

20140111861 | RED OMNIDIRECTIONAL STRUCTURAL COLOR MADE FROM METAL AND DIELECTRIC LAYERS - A multilayer stack displaying a red omnidirectional structural color. The multilayer stack includes a reflector layer, a dielectric layer extending across the reflector layer, and an absorbing layer extending across the dielectric layer. The dielectric layer reflects more than 70% of incident white light that has a wavelength greater than 580 nanometers (nm). In addition, the absorbing layer absorbs more than 70% of the incident white light with a wavelength less than 580 nm. In combination, the reflector layer, dielectric layer, and absorbing layer form an omnidirectional reflector that reflects a narrow band of electromagnetic radiation with a center wavelength between 580-680 nm, has a width of less than 200 nm wide and a color shift of less than 100 nm when the reflector is viewed from angles between 0 and 45 degrees. | 04-24-2014 |
20140290711 | METHOD OF PRODUCING THERMOELECTRIC MATERIAL - A process for manufacturing a thermoelectric material having a plurality of grains and grain boundaries. The process includes determining a material composition to be investigated for the thermoelectric material and then determining a range of values of grain size and/or grain boundary barrier height obtainable for the material composition using current state of the art manufacturing techniques. Thereafter, a range of figure of merit values for the material composition is determined as a function of the range of values of grain size and/or grain boundary barrier height. And finally, a thermoelectric material having the determined material composition and an average grain size and grain boundary barrier height corresponding to the maximum range of figure of merit values is manufactured. | 10-02-2014 |
