PREPARATION OF NANOPOROUS METAL FOAM FROM HIGH NITROGEN TRANSITION METAL COMPLEXES
Nanoporous metal foams monoliths of very high surface area and very low density are prepared by ignition of high nitrogen transition metal complexes. The ammonium salts of iron (III) tris[bi(tetrazolato)-amine], cobalt(III) tris(bi(tetrazolato)amine), were prepared as loose powders, pressed into pellets and wafers, and ignited under an inert atmosphere.

CARBON NANOFIBRE COMPOSITES, PREPARATION AND USE
A carbon nanofibre composite of bulk density of ? 800kg/m3, is produced by growing carbon nanofibres on the surface of a supported carbon fibre, giving a catalyst based on nickel, cobalt, iron, ruthenium by decomposition of a hydrocarbon, for a sufficient period of time to produce the required bulk density.

NANO-PRECIPITATION STRENGTHENED ULTRA-HIGH STRENGTH CORROSION RESISTANT STRUCTURAL STEELS
"A nanocarbide precipitation strengthened ultrahigh-strength, corrosion resistant, structural steel possesses a combination of strength and corrosion resistance contains by about 8 to 17 % cobalt (Co) and a wide range of other elements. The alloy is useful for applications such as aircraft landing gear, machinery and tools used in hostile environments."

"Newman, D. M.; Wears, M. L.; Jollie, M. I."
METHOD FOR MAKING A NANO-PARTICULATE MEDIUM
"A nano-particulate medium is made by sputtering onto a substrate in predetermined quantities, platinum, silicon nitride and a nitride of a magnetic element preferably cobalt which will disassociate, releasing nitrogen under rapid thermal processing in a vacuum to a temperature which allows the formation of a PtCo alloy in a tetragonal crystalline form."

SINGLE-WALLED CARBON NANOTUBE-CERAMIC COMPOSITES AND METHODS OF USE
"A particle comprising a ceramic support (e.g., silica) and small amount of catalytic metal, e.g., cobalt and molybdenum is used as the catalyst for the production of the single-walled carbon nanotubes (SWNTs). The nanotube-ceramic composite thus produced can be used ""as prepared"" without further purification providing significant cost advantages. "

"Bonnot, A-M.; Bouchiat, V.; Faucher, M."
CARBON NANOTUBE GROWTH METHOD
"Carbon nanotubes are grown on a substrate using a hot-wire-assisted chemical vapour deposition method, by first depositing a bilayer of titanium and cobalt on the substrate such that: the thickness of the titanium layer is 0.5-5 nm, the thickness of the cobalt layer is 0.25-10 nm, and the thickness of the cobalt layer is between half and double that of the titanium layer."
