Ni/YSZ electrodes structures optimized for increased electrolysis performance and durability

Electrolysis-reducing electrodes for electrokinetic devices.

Direct current electrokinetic systems generally require Faradaic reactions to occur at a pair of electrodes to maintain an electric field in an electrolyte connecting them. The vast majority of such systems, e.g. electrophoretic separations (capillary electrophoresis) or electroosmotic pumps (EOPs), employ electrolysis of the solvent in these reactions. In many cases, the electrolytic products,...

PERFORMANCE OF AB, ALLOYS FOR HYDROGEN STORAGE AND HYDRIDE ELECTRODES

Two types of hydride electxodes are potential candidates to replace the Cd elecsode in NilCd batteries, One is of the A type where A is a rare earth metal or mixture thereof, and B is the transition metal. The other is commonly referred to as A type. A , type alloys with partial substitution of the B element in A type hydride material (Ovonic) with Co, Mn, Al, and Fe were studied (A compo...

The Durability of Implanted Electrodes and Leads

Implanted neuroprosthetic systems have been successfully utilized to provide upper extremity function for over 15 years. A critical aspect of these implanted systems is the safety, stability and reliability of the stimulus delivery components. These components are: 1) the stimulating electrode itself, 2) the electrode lead, and 3) the lead-to-device connector. A failure in any of these componen...

Duracrete – Probabilistic Performance Based Durability Design of Concrete Structures

The presented project is a first attempt to make probabilistic performance based durability designs of concrete structures. The performance based durability design is based upon realistic models that describes the future behaviour of the concrete and the environment. To make calculations it is necessary to quantify the parameters included in the chosen models. In this paper two models that desc...
