Hydrogen transport through Pd and metal-hydrides has been usually investigated by using potentiostatic current transient technique (chronoamperometry), on the basis of the diffusion-controlled model. This assumes that hydrogen diffusion in the electrode is very slow, while other reactions including interfacial charge transfer and hydrogen transfer are too fast to influence hydrogen transport, a...

We compute the Bohmian trajectories of the incoming scattering plane waves for Klein’s potential step in explicit form. For finite norm incoming scattering solutions we derive their asymptotic space-time localization and we compute some Bohmian trajectories numerically. The paradox, which appears in the traditional treatments of the problem based on the outgoing scattering asymptotics, is absent.

A theory is presented which describes the transient current response to a potential step at a wall-jet electrode, thus defining the “response time” of the electrode. Results are given in the form of a normalized transient as a function of a dimensionless time parameter which permits the analysis of experimental data for electrodes of any geometry and for any solution flow rate.

In this paper, we show a general way to interpret the infrastructure of a global field of arbitrary unit rank. This interpretation generalizes the prior concepts of the giant-step operation and f -representations, and makes it possible to relate the infrastructure to the (Arakelov) divisor class group of the global field. In the case of global function fields, we present results that establish ...

We discuss the nonabelian world-volume action which governs the dynamics of N coincident Dp-branes. In this theory, the branes’ transverse displacements are described by matrix-valued scalar fields, and so this is a natural physical framework for the appearance of noncommutative geometry. One example is the dielectric effect by which Dp-branes may be polarized into a noncommutative geometry by ...
