A Study of the Charge Transport Process at Nickel Hydroxide-Gold Modified Electrodes employing Rotating Disc Electrode Voltammetry and Ac Impedance Measurements
(Scienctific Online, 2014-02)
The aim of the present work was study how the charge-transport process of a nickel hydroxide film electrochemically synthesized on a gold substrate is modified when the electrode is stored without use for long time. It was ...
Diffusion-reaction studies in low permeability shale using X-ray radiography with cesium
An X-ray radiography method for the determination of diffusion coefficients in rock has been modified to provide an estimation of diffusion-reaction parameters for the sorbing tracer, cesium (Cs+ ). Cesium tracer diffusion ...
Diffusion behavior in Nickel–Aluminum and Aluminum-Uranium diluted alloys
(Elsevier Science, 2014-07)
Impurity diffusion coefficients are entirely obtained from a low cost classical molecular statics technique (CMST). In particular, we show how CMST is appropriate in order to describe the impurity diffusion behavior mediated ...
Diffusion behavior of Cr diluted in bcc and fcc Fe: Classical and quantum simulation methods
(Elsevier Science Sa, 2015-07)
Abstract We characterize the atomic mobility behavior driven by vacancies, in bcc and fcc Fe-Cr diluted alloys, using a multi-frequency model. We calculate the full set of the Onsager coefficients and the tracer self and ...
The Role Of Rotational Mechanisms In Electron Swarm Parameters At Low Reduced Electric Field In N-2, O-2 And H-2
(IOP PUBLISHING LTDBRISTOL, 2015)
Diffusion of elastic waves in a two dimensional continuum with a random distribution of screw dislocations
We study the diffusion of anti-plane elastic waves in a two dimensional continuum by many, randomly placed, screw dislocations. Building on a previously developed theory for coherent propagation of such waves, the incoherent ...

Direct Imaging of Long-Range Exciton Transport in Quantum Dot Superlattices by Ultrafast Microscopy
(American Chemical Society, 2016-07)
Long-range charge and exciton transport in quantum dot (QD) solids is a crucial challenge in utilizing QDs for optoelectronic applications. Here, we present a direct visualization of exciton diffusion in highly ordered ...
