One tequila, two tequila, three... diamonds?

On occasion I come across articles that might be dismissed as 'fringe science' and some are wishful thinking while others sound crazy but might actually work. So it is that I came across the headline of "Scientists Turn Tequila Into Diamonds" today! :eek:

Not sure what to expect, I was thinking it'd be a "National Enquire" type story but, surprise, it is for real. And it works.

Whoever thought that science was a dry subject might change their mind after learning about a new discovery in which tequila is turned into diamonds. A team of Mexican scientists found that the heated vapor from 80-proof (40% alcohol) tequila blanco, when deposited on a silicon or stainless steel substrate, can form diamond films.

The key to the surprising discovery is tequila's ratio of hydrogen, oxygen, and carbon, which lies within the "diamond growth region." The resulting diamond films could have inexpensive commercial applications as electrical insulators, say researchers Javier Morales, Luis Miguel Apátiga, and Víctor Manuel Castaño from the National Autonomous University of Mexico (Morales is also with Nuevo León´s Autonomous University).

Originally, the scientists were experimenting with creating diamonds from organic solutions such as acetone, ethanol, and methanol. They found that diluting ethanol in water resulted in high quality diamond films. The scientists then noticed that the ideal compound of 40 percent ethanol and 60 percent water was similar to the proportion used in tequila.

"To dissipate any doubts, one morning on the way to the lab I bought a pocket-size bottle of cheap white tequila and we did some tests," Apátiga said. "We were in doubt over whether the great amount of chemicals present in tequila, other than water and ethanol, would contaminate or obstruct the process, it turned out to be not so. The results were amazing, same as with the ethanol and water compound, we obtained almost spherical shaped diamonds of nanometric size. There is no doubt; tequila has the exact proportion of carbon, hydrogen and oxygen atoms necessary to form diamonds."
