Steady-state currents at inlaid and recessed microdisc electrodes for first-order EC′ reactions

Adaptive Finite Element Simulation of Steady State Currents at Microdisc Electrodes to a Guaranteed Accuracy

Steady-state limiting currents at finite conical microelectrodes.

The investigation of steady-state diffusion-limiting currents at finite conical microelectrodes is reported. Such electrodes are of particular interest as probes in studies of kinetic reactions, measurements in microenvironments, and high-resolution electrochemical imaging. The diffusion-limiting currents were calculated using numerical (finite element) analysis and compared to those obtained a...

Evaluation technique of kinetic parameters for irreversible charge transfer reactions from steady-state voltammograms at microdisk electrodes

An explicit approximate expression for half-wave potentials of irreversible steady-state current-voltage curves at a microdisk electrode was derived from the diffusion equation and the Butler-Volmer equation on the basis of the previous analytical method (J. E. C., 235 (1987) 87). The plot of the half-wave potential, E1/2, against ln(1-exp(-(E1/2E))F/RT)] showed a linear relation with the slope...

Quantum Computing with Steady State Spin Currents

Sutton, Brian M. M.S.E.C.E., Purdue University, December 2013. Quantum Computing with Steady State Spin Currents. Major Professor: Supriyo Datta. Many approaches to quantum computing use spatially confined qubits in the presence of dynamic fields to perform computation. These approaches are contrasted with proposals using mobile qubits in the presence of static fields. In this thesis, steady st...

Steady-state currents in sharp stochastic ratchets.

We develop and analyze a model for particle transport in a stochastic ratchet with a periodic piecewise linear potential, with diffusion coefficient D, where the force is discontinuous in position and fluctuating in time via additive telegraph noise with correlation time tau. We find asymptotic formulas for the steady-state particle current J for large and small D and tau. For example, for smal...
