Scientists Turn Tequila Into Diamonds

tequila.jpgAccording to a new paper that’s just been published by, 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.

Surprisingly, tequila’s ratio of hydrogen, oxygen and carbon 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.

Original experiments used organic solutions such as acetone, ethanol, and methanol. The scientists then noticed that the perfect 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.”

The final diamond film was hard and heat-resistant - properties that could make the diamond useful as coatings for cutting tools, high-power semiconductors, radiation detectors and optical-electronic devices.

The product should be ready for commercial application in 2011, but for now, they are just testing different tequilas to figure out which one gives them the best diamonds/ margaritas.

Blanco, huh? Guess nobody wanted to test this experiment on a good bottle of Anejo. What makes someone come up with the idea to use tequila to make diamonds anyway?

They needed a new marketing gimmick…the worm thing is over 60yrs old afterall. ;)
