| 20080241050 | SEMICONDUCTING AEROGELS FROM CHALCOGENIDO CLUSTERS WITH BROAD APPLICATIONS - Soluble chalcogenido clusters together with transition metal ions and main group elements are shown to provide gels having interconnected, open frameworks. Following supercritical drying with liquid carbon dioxide, the chalcogels may be converted to aerogels. The aerogels possess high internal surface areas with a broad pore size distribution that is dependent upon the precursors used and the aging conditions applied. Some of the gels are encompassed by formulas such as M | 10-02-2008 |
| 20100025616 | MECHANICAL STRENGTH & THERMOELECTRIC PERFORMANCE IN METAL CHALCOGENIDE MQ (M=Ge,Sn,Pb and Q=S, Se, Te) BASED COMPOSITIONS - Thermoelectric eutectic and off-eutectic compositions comprising a minor phase in a thermoelectric matrix phase are provided. These compositions include eutectic and near eutectic compositions where the matrix phase is a chalcogenide (S, Se, Te) of Ge, Sn, or Pb or an appropriate alloy of these compounds and at least one of Ge, Ge | 02-04-2010 |
| 20100292065 | NONLINEAR OPTIC GLASSY FIBER, METHODS OF MAKING AND APPLICATIONS OF THE SAME - A process for producing an optical glass fiber from crystal-glass phase material. In one embodiment, the process includes the step of providing a molten crystal-glass phase material in a container, wherein the temperature of the molten crystal-glass phase material is at or above the melting temperature of the molten crystal-glass phase material, T | 11-18-2010 |
| 20110042607 | THERMOELECTRIC COMPOSITIONS AND PROCESS - A process for producing bulk thermoelectric compositions containing nanoscale inclusions is described. The thermoelectric compositions have a higher figure of merit (ZT) than without the inclusions. The compositions are useful for power generation and in heat pumps for instance. | 02-24-2011 |
| 20110073797 | THERMOELECTRICS COMPOSITIONS COMPRISING NANOSCALE INCLUSIONS IN A CHALCOGENIDE MATRIX - Composites comprising a continuous matrix formed from compounds having a rock salt structure (represented by the structure “MQ”) and inclusions comprising chalcogenide compounds having a rock salt structure (represented by the structure “AB”) are provided. Composites having the structure MQ-ABC | 03-31-2011 |
| 20110248209 | THERMOELECTRIC FIGURE OF MERIT ENHANCEMENT BY MODIFICATION OF THE ELECTRONIC DENSITY OF STATES - A thermoelectric material and a method of using a thermoelectric material is provided. The thermoelectric material can include at least one compound. For example, the at least one compound may be a Group IV-VI compound such as lead telluride. The at least one compound may further include one or more dopants such as sodium, potassium, and thallium. The method of using a thermoelectric material can include exposing at least one portion of the at least one compound to a temperature greater than about 700 K. | 10-13-2011 |
| 20110290735 | CHALCOGENIDE COMPOUNDS FOR THE REMEDIATION OF NUCLEAR AND HEAVY METAL WASTES - Chalcogenide compounds, including ternary and quaternary tin and antimony chalcogenides, for use as absorbents in the remediation of hazardous materials are provided.
