  • Patent number: 9833836
    Abstract: Provided is a composition including a plurality of multi-metallic nanoparticles each consisting essentially of a core including at least one first metal (Me1) and a continuous shell including atoms of at least one second metal (Me2). Optionally, the continuous shell of Me2 atoms protects the Me1 atoms from oxidation at all temperatures less than 150° C.

  • Publication number: 20120241693
    Abstract: The invention relates to a method for preparing an aqueous-based dispersion of metal nanoparticles comprising: (a) providing an aqueous suspension of a metal salt; (b) pre-reducing the metal salt suspension by a water soluble polymer capable of metal reduction to form a metal nuclei; and (c) adding a chemical reducer to form metal nanoparticles in dispersion. The invention further relates to aqueous-based dispersions of metal nanoparticles, and to compositions such as ink comprising such dispersions.
