Permittivity And Permeability

In this paper, we got Ni-MWNTs through pretreatment of MWNTs and electroless plating of nickel, and observed the Ni-MWNTs and MWNTs with TEM and FTIR. In addition, we prepared Ni-MWNTs/EP and MWNTs/EP composites. The volume resistivity、permittivity and permeability of composites were measured. Results showed that the volume resistivity of Ni-MWNTs/EP was higher than MWNTs/EP’s when volume fraction was lower than 8%. The ε" of Ni-MWNTs/EP was larger than MWNTs/EP’s. It indicated that Ni-MWNTs/EP had better electromagnetic energy storing and consumption capacity. And the permeability of Ni-MWNTs/EP would increase with the increasing of Ni-MWNTs. Ni-MWNTs/EP had some ferromagnetism.

A Current

A current theme in the study of the critical current density behavior of YBa2Cu3O7-δ (YBCO) grain boundaries is that their electromagnetic properties are heterogeneous on various length scales ranging from 10s of microns to ˜ 1 Å. Recently, combined electromagnetic and TEM studies on four flux-grown bicrystals have demonstrated a direct correlation between the length scale of the boundaries’ saw-tooth facet configurations and the apparent length scale of the electrical heterogeneity. In that work, enhanced critical current densities are observed at applied fields where the facet period is commensurate with the spacing of the Abrikosov flux vortices which must be pinned if higher critical current density values are recorded. To understand the microstructural origin of the flux pinning, the grain boundary topography and grain boundary dislocation (GBD) network structure of [001] tilt YBCO bicrystals were studied by TEM and HRTEM.
