An electrolysis cell comprises a housing receiving a plurality of parallel electrodes separated by guides to define a plurality of passageways through which an electrolyte solution is flowed from an inlet end to an outlet end, the solution being subjected to electrolysis by applying an electrical potential between electrodes. At the inlet and outlet ends, spaced wall means engage with the electrodes to extend the electrolyte passageways and confine electrolyte to the respective passageways where...

A rapid, simple-to-use method for preparing hybrid cells, applicable to fully differentiate, non-dividing cells, entails bringing at least two different cells into contact under conditions that promote cell fusion and then purifying the resultant hybrid without antibiotic or metabolic selection. This approach yields hybrid cells useful in a variety of applications, including clinical treatment regimens, as cellular modulators of the immune system.

A solid oxide fuel cell, comprising: a ferritic stainless steel substrate including a porous region and a non-porous region bounding the porous region; a ferritic stainless steel bi-polar plate located under one surface of the porous region of the substrate and being sealingly attached to the non-porous region of the substrate about the porous region thereof, a first electrode layer located over the other surface of the porous region of the substrate; an electrolyte layer located over the first ...

An electrolysis cell for recovery of metals that are lighter than the electrolyte used in the cell. The cell makes use of multiple electrode assemblies, and each assembly is provided with an individual hood at the top forming a gas collection chamber. The hood of each assembly collects gas generated by the assembly and isolates the gas thus generated from gas generated by other assemblies and from metal collecting in the cell outside the hoods. The invention also relates to an integrated unit ma...

Provided is a method for introducing a substance into a cell, which method comprises: (a) contacting the cell with a recognition agent to bind the recognition agent to a recognition site on the surface of the cell; and (b) separating the recognition agent from the cell thereby forming a hole in the surface of the cell. Kits for use in such methods are also provided.

Organic photosensitive optoelectronic devices are disclosed. The devises are thin-film crystalline organic optoelectronic devices capable of generating a voltage when exposed to light, and prepared by a method including the steps of: depositing a first organic layer over a first electrode; depositing a second organic layer over the first organic layer; depositing a confining layer over the second organic layer to form a stack; annealing the stack; and finally depositing a second electrode over t...

A dehydrated composition is provided that includes freeze-dried erythrocytic cells. Alcohol (e.g., sterol or cholesterol) is at least partially removed from erythrocytic cells including erythrocytic membranes. After removal of at least part of the alcohol, the erythrocytic cells have a low phase transition temperature range, an intermediate phase transition temperature range, and a high phase transition temperature range. The erythrocytic cells may be loaded with an oligosaccharide (e.g., trehal...

A fuel cell sensor (10) comprises a main body (11) in which are mounted working electrodes (12), counter electrodes (13) and respective contacts (14 to 17). The working electrodes (12) are mounted facing each other to define a sample space between them. The electrodes (12) are electrically interconnected in parallel as are the two counter electrodes (13). This arrangement makes it possible to provide a very large working electrode surface area for a small volume sample space (22).

In accordance with the present invention, it has been discovered that a major reason for the failure to achieve successful in vivo transplantation in large mammalian species has been flaws associated with the design of microcapsules taught in the prior art, flaws in the method of making such microcapsules, and a lack of tests to determine if a given microcapsule will be successful. In accordance with the present invention, a number of functional properties which must be met by a microcapsule in ...
