In summary, the loading amount of a noble metal
catalyst greatly influences the performance.
Import Value of Watch Cases & Watches Made of Noble Metal
resist oxidation and include many of the precious metals, such as platinum, palladium, iridium and gold.
Researchers at the University of Wisconsin have discovered a cheap and efficient alternative to the use of noble gases as a catalyst in hydrogen production -- a combination of phosphorus and sulfur (common elements) and cobalt, a metal 1,000 times cheaper than the cheapest noble metals
Typical roles for Tegal's etching systems used in MEMS and biochip fabrication include producing structures in silicon, silicon nitride, and silicon dioxide, in organic materials like BCB and polyimide and in noble metals
, like platinum and gold.
As well as the economic ramifications this technology may have, this ability to make a `crop of gold' opens up the way for the phyto- extraction of other noble metals
Catalytic combustion using raised temperatures (392-752F/200-400C) and supported catalyst beds, often used with noble metals
such as platinum or palladium, can be very effective in reducing fumes to basic elemental constituents including nitrogen and hydrogen, and eliminating VOCS.
It is also significant that the catalyst can break the carbon-hydrogen bonds in hydrocarbons such as cyclohexane, the precursor of nylon, without using noble metals
There's another 30 noble metals
that are available as enriched isotopes, and they have a different chelator molecule.
There are no noble metals
involved, so it should be very cheap," he said.
Current fuels cells operate at a red-hot 800+ degrees Celsius, which requires the use of expensive noble metals
According to ECD Ovonics, the work will focus on Ovonic's Metal Hydride Fuel Cell technology, which does not utilize noble metals
traditionally used as catalysts for fuel cells.
