摘要: A magnetocaloric material comprising a La—Fe—Si based alloy composition that is compositionally modified to include a small but effective amount of at least one of Al, Ga, and In to improve mechanical stability of the alloy (substantially reduce alloy brittleness), improve thermal conductivity, and preserve comparable or provide improved magnetocaloric effects. The alloy composition may be further modified by inclusion of at least one of Co, Mn, Cr, and V as well as interstitial hydrogen.

摘要: Disclosed herein are embodiments of an enhanced resonant frequency hexagonal ferrite material and methods of manufacturing. The hexagonal ferrite material can be Y-phase strontium hexagonal ferrite material. In some embodiments, strontium can be substituted out for a trivalent or tetravalent ion composition including potassium, thereby providing for advantageous properties.

摘要: The invention includes miniature dots, miniature disks or miniature cylinders and methods of making the same by dispersing a particle in or on a dissolvable, meltable or etchable layer on a substrate, a portion of the particle exposed above a surface of the dissolvable, meltable or etchable layer; depositing a mask on the particles and the dissolvable substrate; removing the particles from the layer; etching an array of nanoholes in the substrate; depositing one or more metallic layers into the nanoholes to form an array of dots, disks or cylinders; and dissolving the dissolvable layer with a solvent to expose the dots, disks or cylinders. The dots, disks or cylinders can be included with two sets of microelectrodes for ultrahigh speed rotation of miniature motors, and/or can be designed with a magnetic configuration into miniature motors for uniform rotation speeds and prescribed angular displacement. The invention also includes modified diatom frustules, and miniature motors containing modified diatom frustules.

摘要: This invention relates to magnetocaloric materials comprising alloys useful for magnetic refrigeration applications. In some embodiments, the disclosed alloys may be Cerium, Neodymium, and/or Gadolinium based compositions that are fairly inexpensive, and in some cases exhibit only 2nd order magnetic phase transitions near their curie temperature, thus there are limited thermal and structural hysteresis losses. This makes these compositions attractive candidates for use in magnetic refrigeration applications. Surprisingly, the performance of the disclosed materials is similar or better to many of the known expensive rare-earth based magnetocaloric materials.

摘要: In one aspect of an inventive concept, a product includes a substrate and a material formed from a precursor powder, where the material includes a plurality of particles from the precursor powder deposited on the substrate. The plurality of particles have structural characteristics defined by an impact of the particles on the substrate and/or on previously deposited particles. Moreover, the material has a microstructure, where the microstructure of the material is substantially the same as a microstructure of the precursor powder. The microstructure of the material is characterized by at least one property, where the at least one property is substantially the same as a corresponding at least one property of the precursor powder.
