    Abstract: A method of fabricating composite filaments is provided. An initial composite filament including a core and a cladding (such as a Pt-group metal) is cut into smaller pieces (or is first mechanically reduced and then cut into smaller pieces). The smaller pieces of the filaments are inserted into a metal matrix, and the entire structure is then further reduced mechanically in a series of reduction steps. The process can be repeated until the desired cross sectional dimension of the filaments is achieved. The matrix can then be chemically removed to isolate the final composite filaments with the cladding thickness down to the nanometer range. The process allows the organization and integration of filaments of different sizes, compositions, and functionalities into arrays suitable for various applications.

  • Publication number: 20140228201
    Abstract: Method for producing a substrate with Au (gold) nanoclusters affixed to the surface thereof and substrate and catalyst obtained by means of said method. The method consists in preparing a solution containing, in disperse form, Au nanoclusters and, also in disperse form, a substrate with a surface functionalised with a polyelectrolyte that confers a net electric charge thereon, and in intensely agitating said solution to affix Au nanoclusters to the substrate surface. This results in a substrate that has a surface with Au nanoclusters affixed in disperse form, significantly without clusters. The invention also relates to a catalyst that comprises said substrate with Au nanoclusters affixed to the surface thereof. Said catalyst is particularly suitable for use in oxidation reactions.
