Fabrication of Ag-Doped Y₁Ba₂Cu₃O_7-x Superconducting Films on Cu Substrates by Electrophoretic Deposition

Abstract

In a toy model of gauge and gravitational interactions in D ≥ 4 dimensions, endowed with an invariant UV cut-off Λ, and containing a large number N of non-selfinteracting matter species, the physical gauge and gravitational couplings at the cut-off, α g ≡ g 2 Λ D−4 and α G ≡ G N Λ D−2 , are shown to be bounded by appropriate powers of 1/N . This implies that the infinite-bare-coupling (so-called compositeness) limit of these theories is smooth, and can even resemble our world. We argue that such a result, when extended to more realistic situations, can help avoid large-N violations of entropy bounds, solve the dilaton stabilization and GUT-scale problems in superstring theory, and provide a new possible candidate for quintessence.

Magnetic shielding performances of YBa2Cu3O7−δ-coated silver tubes obtained by electrophoretic deposition

“…The preparation of YBa 2 Cu 3 O 7−δ (YBCO) thick films by EPD was reported by several groups, using either ketonebased [17][18][19][20] or alcohol-based [21][22][23][24] suspensions.…”

A comparison of the artificial neural network model and the theoretical model used for expressing the kinetics of electrophoretic deposition of YSZ on LSM

“…However, these processes are limited to relatively simple shapes. Recently, electrophoretic deposition (EPD) of ceramic powders has been successfully applied for various applications in the fields of superconducting coating production [3][4][5][6], the manufacture of phosphor screens [7,8], and fuel cell creation [9][10][11][12].…”

Electrochemical Synthesis of Ceramic Materials. 4. Electrophoretic Deposition of Metal Nitride Ceramic Precursors

“…The advantages of this method are that it does not require expensive equipment, and it has the potential for coating irregularly shaped objects. These advantages have previously been recognized and used to prepare other types of ceramic coatings, − and a recent review of this subject provides insight into both the experimental and theoretical development of this approach . Preceding our work, Moritiz and Reetz described a process for electrophoretically depositing AlN coatings on Pt substrates…”
