The present invention relates to a polymeric material having one or more nanoparticles embedded within the surface layer of a single side of the material. In some embodiments, the nanoparticles are microbiocidal nanoparticles which impart antimicrobial characteristics to the polymeric material within which they sprayed and pushed by are embedded.

Embedding nanoparticles in thermoplastic polymers

A mixture of powders for preparing a sintered nickel-titanium-rare earth (Ni&#x2014;Ti&#x2014;RE) alloy includes Ni&#x2014;Ti alloy powders comprising from about 55 wt. % Ni to about 61 wt. % Ni and from about 39 wt. % Ti to about 45 wt. % Ti, and RE alloy powders comprising a RE element.

Mixture of powders for preparing a sintered nickel-titanium-rare earth metal (Ni-Ti-RE) alloy

A nickel-titanium-rare earth (Ni&#x2014;Ti-RE) alloy comprises nickel at a concentration of from about 35 at. % to about 65 at. %, a rare earth element at a concentration of from about 1.5 at. % to about 15 at. %, boron at a concentration of up to about 0.1 at. %, with the balance of the alloy being titanium. In addition to enhanced radiopacity compared to binary Ni&#x2014;Ti alloys and improved workability, the Ni&#x2014;Ti-RE alloy preferably exhibits superelastic behavior. A method of processing a Ni&#x2014;Ti-RE alloy includes providing a nickel-titanium-rare earth alloy comprising nickel at a concentration of from about 35 at. % to about 65 at. %, a rare earth element at a concentration of from about 1.5 at. % to about 15 at. %, the balance being titanium; heating the alloy in a homogenization temperature range below a critical temperature; and forming spheroids of a rare earth-rich second phase in the alloy while in the homogenization temperature range.
