A series of three articles present an innovative way to build advanced functionally graded materials (FGM) based on polymer/ceramic composites tailored by electrophoresis from the process principle their field grading application in power electronics. In this Part 1, is presented and relies applying a DC voltage liquid composite compound before curing order `freeze' particles where they have be...

The nonlinear response of noninteracting sBlochd electrons is examined within a nonequilibrium formalism on the infinite-dimensional hypercubic lattice. We examine the effects of a spatially uniform, but time-varying electric field signoring magnetic-field effectsd. The electronic Green’s functions, Wigner density of states, and time-varying current are all determined and analyzed. We study bot...

The application of an electric field to a suspension of charged particles can lead to the formation of patterns due to electrohydrodynamic instabilities which remain poorly understood. We elucidate this behavior by visualizing the dynamics of charged carbon black particles suspended in a nonpolar solvent in response to an electric field. As the particles are transported across a microfluidic ch...

An exact formalism for calculating the retarded and advanced Green's functions of strongly correlated lattice models in a uniform electric field is derived within dynamical mean-field theory. To illustrate the method, we solve for the nonequilibrium density of states of the Hubbard model in both the metallic and Mott-insulating phases at half-filling (with an arbitrary strength electric field) ...

The evolution of the charge density distribution function is simulated for both the case of a uniformly charged sphere with zero initial conditions and for the case of a non-uniform charged sphere. For the case of a uniformly charged sphere, the comparison of a numerical result and an exact analytical solution, demonstrated the agreement between the results. The process of “scattering” of a cha...

C. elegans will orient and travel in a straight uninterrupted path directly towards the negative pole of a DC electric field. We have sought to understand the strategy worms use to navigate to the negative pole in a uniform electric field that is fixed in both direction and magnitude. We examined this behavior by quantifying three aspects of electrotaxis behavior in response to different applie...

Abstract In four dimensional general relativity, the fact that a Killing vector in a vacuum spacetime serves as a vector potential for a test Maxwell field provides one with an elegant way of describing the behaviour of electromagnetic fields near a rotating Kerr black hole immersed in a uniform magnetic field. We use a similar approach to examine the case of a five dimensional rotating black h...

[1] We infer the vertical profiles of space charge density and electric field intensity above ground by comparing modeling and measurements of the ground‐level electric field changes caused by elevating grounded lightning‐triggering wires. The ground‐level electric fields at distances of 60 m and 350 m were measured during six wire launches that resulted in triggered lightning. The wires were l...
