    Patent Number:
    US 6869671 B2
    Description:

    A thin film based nanoporous alumina template has been developed which allows the in situ removal of an electrically insulating alumina barrier layer at the pore bases. This barrier free nanoporous system has great utility for electrodeposition of a wide variety of nanowire materials. An exemplary multilayer thin film precursor is provided comprising Al (anodization layer), Ti (diffusion barrier) and Pt (active electrode) on a Si substrate. Aluminum anodization in sulfuric acid with a subsequ…

    Patent Number:
    US 5747180 B2
    Description:

    A method of fabricating two-dimensional regimented and quasi periodic arrays of metallic and semiconductor nanostructures (quantum dots) with diameters of .about.100 .ANG.(10 nm) includes the steps of polishing and anodizing a substrate to form a regimented quasi-periodic array of nanopits. The array forms a template for metallic or semiconductor material. The desired material is deposited in the nanopits by immersing the substrate in an appropriate solution and using the substrate as one cat…

    Albert E. Miller, Gautam Banerjee
    Patent Number:
    US 6183547 B2
    Description:

    A composition for inhibiting corrosion of metal surfaces comprises permanganate and a very low concentration of chromium (VI). The concentration of chromium (VI) in the aqueous solution is less than about 100 micrograms per liter, and the concentration of permanganate is about 0.2% to about 20% by weight of the aqueous solution. In another embodiment of the invention, a composition for inhibiting corrosion of metal surfaces includes permanganate and acetic acid. The concentration of acetic ac…
