Abstract: A dye-sensitised photovoltaic cell is provided, the cell comprising a first, transparent, electrode facing a second electrode, wherein at least one of the first and second electrodes is provided with an electrically-conductive material comprising (A) one or both of nickel and cobalt, and (B) one or more of phosphorous, boron, manganese, iron, tungsten, molybdenum, chromium, tin, zinc and palladium, wherein the total content of (A) the nickel and cobalt in said electrically-conductive material is from 80 to 96 wt % of the electrically-conductive material, and total content of (B) the phosphorous, boron, manganese, iron, tungsten, molybdenum, chromium, tin, zinc and palladium in said electrically-conductive material is from 4 to 20 wt % of the electrically-conductive material.

Abstract: A method of obstructing metal whisker growth that includes providing a conductive structure comprised of a whisker forming metal, and forming a composite coating on the whisker forming metal. The composite coating may include a matrix phase of a polymer and a dispersed phase of reinforcing particles. The reinforcing particles are incorporated into the polymer to provide the composite coating with mechanical properties that obstruct whiskers from penetrating through the composite coating.

Abstract: A system-to-reservoir connector is disclosed in which a system-side-sub-connector and a reservoir-side-sub-connector provide for a fluid connection that is resilient to external forces, is substantially leak-proof upon insertion and retraction, and is orientation independent.

Abstract: A heat transfer arrangement for one or more heat-generating components (18a) on a printed-circuit board (16) includes a heat transfer plate (316) defining an aperture (416) registered with the components. A "vertically" movable heatsink adapter (410) is adjusted to juxtapose its "lower" surface with the "upper" surface of the components to be heat-sunk. A heat-transfer pad (318) may be used between the heatsink adapter (410) and the component (18a). In various embodiments, the heatsink adapter takes the form of circular (410) or rectangular (410R) plugs, a draw-tube (808) arrangement, or a bellows (1010).
