Abstract: The present invention provides a galvanic cell having an aluminum anode and a cathode compartment design suitable for carrying out the aqueous electrochemical reaction between solid aluminum metal and aqueous peroxide ions. The galvanic cell is activated when water, aqueous hydroxide solution, or an aqueous salt solution is added to the cell. This reaction releases a significant amount of electrochemical energy from a small size (mass or volume) cell. This cell reaction and design leads to an improvement in energy released over state-of-the-art aluminum/hydrogen peroxide galvanic cells.

Abstract: Halogenated organic compounds that are inexpensive and are readily available have been used to present the examples of the invention. These chemicals, when in contact with water experience a reaction that releases oxy-halogenated acid. These compounds are weak acids and release hydrogen ions according to their ionization constant keeping a constant level of oxy-halogenated ion. These ions are capable of reacting with catalytic cathodes and can be coupled with anode materials to fabricate galvanic cells. Exemplary embodiments of the present invention include cells with flat and cylindrical form factors having a variety of anodes.

The sensor components showed good linear response, resolution and mechanical integrity to the harsh ocean environment.

Abstract: An actuated galvanic cell is described which generated electric current responsive to introduction of electrolyte from a secondary containment means. Also housed within the containment means is a propellant which serves to drive the electrolyte from the containment means into the reaction chamber for electric current production. This propellant system is chosen from thermal, phase change, and other systems which as opposed to physical pumps impel the electrolyte into the reaction chamber without the need for additional introduction apparatus.

Abstract: A liquid core waveguide for fluorescence spectroscopy is provided. According to one version of the present invention, a substantially cylindrical support tube is provided, having a substantially constant outer diameter, and a flexible tube is wrapped in contiguous windings about the outer surface of the support tube to form a tight coil about the support tube which is configured of material that is transmissive of light in the relatively short wavelength range which is used to excite the molecular material in the flexible tube. This feature enables the flexible tube to be wound tightly about the support tube without crimping (thereby to form the liquid core waveguide into a compact package), and enables light in the relatively short excitation range to be effectively transmitted through the support tube and into the flexible tube.
