Abstract: A vibrating magnetic assembly includes a housing, a first magnet positioned within the housing and having a first permeance coefficient (Pc1), a second magnet positioned within the housing and spaced from the first magnet, the second magnet having a second permeance coefficient (Pc2), and a third magnet positioned within the housing between the first and second magnets. The third magnet has a third permeance coefficient (Pc3) and is reciprocable between the first and second magnets to cause vibration. A ratio of Pc3:Pc1 and Pc3:Pc2 is greater than 1 such that the N pole of the third magnet is magnetically attracted to the N pole of the first magnet, and the S pole of the third magnet is magnetically attracted to the S pole of the second magnet when the third magnet is positioned within a threshold distance of the respective first or second magnet.

Abstract: A wide aperture permanent magnet structure which is useful in creating a highly uniform longitudinal or solenoidal magnetic field in the working region of the magnet and in which the aperture of the structure can be equal in cross-sectional area to the working region of the magnet. The geometry and magnetization direction of the constituent magnets are chosen to maximize the uniformity of the longitudinal or solenoidal magnetic field in the working region of the magnet while minimizing the overall volume and weight of the structure as well as eliminating the need for magnetic pole pieces made of iron or other high permeability materials. The invention can take the form of a cylindrical shell of permanent magnets to create a solenoidal magnetic field, or a parallel surface arrangement to create a longitudinal magnetic field.

Abstract: A ceramic-ceramic nanocomposite electrolyte having enhanced conductivity is provided. The nancomposite electrolyte is formed from chemically stabilized zirconia such as yttria stabilized zirconia or scandia stabilized zirconia and a heterogeneous ceramic dopant material such as Al2O3, TiO2, MgO, BN, or Si3N4. The nanocomposite electrolyte is formed by doping the chemically stabilized zirconia with the ceramic dopant material and pressing and sintering the composite. The resulting electrolyte has a bulk conductivity of from about 0.10 to about 0.50 S/cm at about 600° C. to about 900° C. and may be incorporated into a solid oxide fuel cell.

Abstract: A permanent magnet is provided which retains its magnetic properties and exhibits a linear extrinsic demagnetization curve at elevated temperatures up to 700° C.
