Abstract: The invention relates to mixed metal borohydrides used for solid hydrogen storage. The mixed metal borohydrides are synthesized through solution synthesis using multiple metal borohydrides. First and second precursor solutions are prepared and combined to create a mixture in which the mixed metal borohydride is formed. The solvent is removed, leaving the mixed metal borohydride. The first precursor solution consisting essentially of lithium borohydride, and the second precursor solution consisting essentially of a borohydride compound containing one or more metal cations selected from the group of metals consisting of sodium, magnesium, calcium and titanium.

Abstract: In a vapor deposition method which can be used to deposit mixtures of materials in progressively varying amounts on a substrate (1) and which can be used for a variety of purposes, but is of especial value in combinatorial chemistry, the path of the vaporized material from the source (3) to the substrate (1) is partially interrupted by a mask (5), the positioning of the mask in a plane parallel to the plane defined by the substrate (1) being such that the material is deposited on the substrate (1) in a thickness which increases substantially continuously in a direction along the substrate (1).

Abstract: An electrochemical cell for testing the electrochemical behavior of a plurality of materials comprises: a first electrode; a counter-electrode bearing an electrochromic material having a visual or measurable property which changes in a manner proportional to the total charge passed through it; and an electrolyte between and in electrical contact with the first electrode and the counter-electrode; wherein one of the first electrode and the electrolyte comprises a plurality of regions, each region comprising a sample of material to be tested, the regions being, in the case of the first electrode, electrically connected to a common terminal. Such a cell can be used for a “combinatorial chemistry” approach to testing the properties of possible cell components.
