  • Dielectric materials for power transfer system
    Patent number: 8968609
    Abstract: A contactless power transfer system is proposed. The power transfer system comprises a field-focusing element comprising a dielectric material. The dielectric material comprises a composition that is selected from the family of (Ba,Sr)TiO3 or CaCu3Ti4O12. The compositions of the (Ba,Sr)TiO3 include the materials such as Ca1-x-yBaxSryTi1-zCrzO3-?Np, wherein 0<x<1; 0<y<1; 0?z?0.01; 0???1; and 0?p?1. The compositions of the CaCu3Ti4O12 include the materials such as Ca1-x-yBaxSry (Ca1-zCuz)Cu2Ti4-?Al?O12-0.5?, wherein 0?x<0.5; 0?y<0.5; 0?z?1; and 0???0.1.

  • APPARATUS AND METHOD FOR PRODUCING PLASMA DURING MILLING FOR PROCESSING OF MATERIAL COMPOSITIONS
    Publication number: 20110297532
    Abstract: An apparatus, such as a plasma generation system, is provided. The apparatus can include a chamber that may be formed, for example, substantially of insulating material. The chamber can be configured to establish therein a stable glow discharge plasma having a pressure of at least about atmospheric pressure while vibrating a sample so as to be milled by bodies contained by the chamber. For example, the chamber may vibrate and/or rotate, and the chamber can include at least one body that includes insulating material and is free within the chamber. Associated methods are also provided.
