Taking tea to III-Vs?

摘要

A new biodegradable machining compound for computer hard drive manufacturing, derived in part from green tea, is three to four times more effective than toxic counterparts. Some 161m hard drives leave assembly lines each year and the new compound could give up to four fold increase in efficiency, reduce hard drive manufacture costs, with less corrosion and less environmental risk. Engineered by John Lombardi of Ventana Research Corporation in Tucson, Arizona, as part of a National Science Foundation Small Business Innovation Research grant, the chemical is part of a slurry that polishes ceramics of aluminum oxide and titanium carbide - used in computer hard drive read-write units.
