(270) Irreversible Electrochemistry of Dispersed Systems

Distribution Systems and Dispersed Generation

Escape problem for irreversible systems.

The problem of noise-induced escape from a metastable state arises in physics, chemistry, biology, systems engineering, and other areas. The problem is well understood when the underlying dynamics of the system obey detailed balance. When this assumption fails many of the results of classical transition-rate theory no longer apply, and no general method exists for computing the weak-noise asymp...

Analysis of Dispersed - Phase Fresh Perspective Systems :

single-particle process Consider a single particle of volume V ( t ) at time t which undergoes random, discontinuous “erosion” to smaller sizes in accord with the probabilistic law: Pr( V ( t + d t ) I u I V ( f ) = u’ 1 = B ( u I u’ )dt We let F( u, t ) be the cumulative distribution function for the size of the single particle undergoing random erosion. Suppose that the cumulative probability...

Controlled structuring of dispersed food systems

Dispersed systems such as emulsions and suspensions are encountered in a large variety of applications areas such as food, cosmetics, pharmaceutics and polymers. To obtain the desired performance of an emulsion the dispersing process, i.e. droplet size distribution has to be monitored and controlled. By combining droplet generation, deformation and fixation in one experimental set-up we aim to ...

Unconventional Electrochemistry in Micro-/Nanofluidic Systems

Electrochemistry is ideally suited to serve as a detection mechanism in miniaturized analysis systems. A significant hurdle can, however, be the implementation of reliable micrometer-scale reference electrodes. In this tutorial review, we introduce the principal challenges and discuss the approaches that have been employed to build suitable references. We then discuss several alternative strate...
