The 2009 chemistry prize goes to Javier Morales, Miguel Apátiga, and Victor M. Castaño (Universidad Nacional Autónoma de México) for creating diamonds from liquid — specifically from tequila.
Abstract from "Growth of Diamond Films from Tequila," Javier Morales, Miguel Apatiga and Victor M. Castano, 2008, arXiv:0806.1485. Diamond thin films were growth using Tequila as precursor by Pulsed Liquid Injection Chemical Vapor Deposition (PLI-CVD) onto both silicon (100) and stainless steel 304 at 850 C. The diamond films were characterized by Scanning Electron Microscopy (SEM) and Raman spectroscopy. The spherical crystallites (100 to 400 nm) show the characteristic 1332 cm-1 Raman band of diamond.
Nature reports that a new form of carbon was created when physicists at the Australian National University in bombarded a carbon target with a laser. As the carbon reached temperatures of around 10000 °C, it formed an intersecting web of carbon tubes called a 'nanofoam'. This is said to be a fifth form of carbon known after graphite, diamond, buckminsterfullerenes (buckyballs), and nanotubes. The foam is attracted to magnets. This may lead to new uses.1
Scientists create fifth form of carbon
Magnetic carbon 'nanofoam' could find medical applications.
Researchers have created a new form of carbon: a spongy solid that is extremely lightweight and, unusually, attracted to magnets. The foam could one day help treat cancer and enhance brain scans, say the inventors.Scientists create fifth form of carbon, , news@nature, 3/2004, (2004)
