Tequila can form diamond film

The tequila diamonds could be used to "detect radiation, coat cutting tools or, above all, as a substitute for silicon in the computer chips of the future," Miguel Apatiga, one of three researchers from the National Autonomous University of Mexico, said Tuesday.
The scientists found that the heated vapor from tequila blanco, when deposited on a stainless steel base, can form diamond films. They began experimenting some 13 years ago with synthetic diamonds made by a technological process, as opposed to natural diamonds produced by geological processes from gases like methane.
Later they produced diamonds from liquids, and then noticed that the ideal compound of 40 percent ethanol and 60 percent water was similar to the proportion used in tequila.
"One day I went to the campus shop and bought a bottle of cheap tequila. I used it under the same experiment conditions as for a test with ethanol and water and obtained positive results," Apatiga said.
The diamonds formed were small crystals, too tiny to be used in jewelry. The scientists are now investigating other applications for tequila diamonds.
