Definition
Nanometer scale, heterogeneously structured crystallines.
Devices
-Quantum dot fluorescent biodetectors
-Copper iron oxide nanopowder, <100 nm particle size
-Copper zinc iron oxide nanopowder, <100 nm particle size
-At nano scale is no longer a metal,becomes a semiconductor
-1-D nanowires, 2-D nanofilms and 3-D supercrystals
Applications
A potential application is to aid firefighters,
who now wear protective masks containing
copper-manganese-oxide. That material's
effectiveness at getting rid of CO, however,
lasts only 15 minutes, while nanogold
protects for several hours. One such reaction is the conversion of carbon-monoxide (CO)
to carbon-dioxide (CO2). Nanogold catalyzes this at room
temperature and with 100-percent efficiency.

Nano Materials - Nanocrystalline Materials
Fullerenes/ Carbon Nanotubes
-Fullerenes are molecules composed of carbon in the shape of hollow
spheres, or ellipsoids; fullerenes in a cyllindrical for are called nanotubes.
Properties
-High tensile strength
-High electrical conductivity
-High ductility
-High resistance to heat
-Due to the lack of surface exposure they have relatively no chemical reactivity

Nano Copper
Properties
-Copper aluminum oxide nanopowder, <100 nm particle size -Copper iron oxide nanopowder, <100 nm particle size
-Copper zinc iron oxide nanopowder, <100 nm particle size Applications
-Bouisol-colloidal copper used as a fungacide since 1931.
-Used an an algaecide in the treatment of water in swimming pools.
-Used in polymers and plastics, lubricants, inks and metallic coatings
-Copper interconnects on silicon chips in computers.
-Argonne National Laboratory (ANL) has recently developed metal nanofluids based on nanoparticles of copper that would have application in improving the efficiency of automobiles, heating/air conditioning systems and industrial equipment.
-Antimicrobial Materials - research is being done at MIT

Nano Gold
-Created in small enough chunks
turns red, yellow, blue and other colors
-Becomes an excellent catalyst at 3-5 nm
-At nano scale is no longer a metal,
becomes a semiconductor

NICKEL- TUNGSTEN ALLOYS
Nano-material which exhebits more stability and safety than that of chrome, but offers the same amount of function in the electro-plating process.
Key Benefits:
Adds a protective coating and shiny luster
Safer than electro-plating with chrome which is a carcinogenic process
Cheaper process than chroming.
Possible Uses:
Electro-plating of many industrial metals, bathroom fixtures, and any other
visible metal objects.
