Abstract: Permanent magnets are used for several important applications, including dc electrical motors, wind turbines, hybrid automobile, and for many other applications. Modern widely used rare-earth based permanent magnet materials, such as Sm—Co and Nd—Fe—B, are generally intermetallic alloys made from rare earth elements and transition metals such as cobalt. However, the high costs of rare earth elements make the widespread use of these permanent magnets commercially unattractive. The present work focuses on producing a new permanent magnet material, with good magnetic properties, which is free from rare-earth elements and thus cost-effective. The present invention provides a process to synthesis boron doped manganese antimonide as an alternative to rare earth based permanent magnet materials. The boron doped manganese antimonide disclosed in this invention is free from rare-earth element with good magnetic properties.

Abstract: Disclosed is a nanostructured p-type copper-selenide as a cost-effective thermoelectric material with a high thermoelectric figure-of-merit. The nanostructured copper-selenide is a cost-effective p-type thermoelectric material having a high figure-of-merit of 2 at 973 K and is synthesized employing high energy ball milling process followed by reaction sintering under pressure at high heating rates using spark plasma sintering of the resulting nanopowders. The sintered copper-selenide shows a density of 99.9% of theoretical density and retains the nanoscale features introduced during ball milling leading to a thermoelectric figure of merit of 2 at 973 K.

Abstract: Scalable structured data store operations can include logging a number of detected corrupted records within a scalable structured data store, repairing the number of corrupted records within a number of nodes of the scalable structured data store, and predicting hardware failure based on the logged number of corrupted records.
