The greater the heat, the greater the local concentration.More heat produced the lighter shades of gray, as seen on the Mona Lisa's forehead and hands, while less heat produced the darker shades in her dress and hair.Each pixel in the "Mini Lisa" image is spaced by 125 nanometers."We envision TCNL will be capable of patterning gradients of other physical or chemical properties, such as conductivity of graphene," physics Professor Jennifer Curtis said. "This technique should enable a wide range of previously inaccessible experiments and applications in fields as diverse as nanoelectronics, optoelectronics and bioengineering."</span></td> </tr> </table></td> </tr> <tr> <td colspan="2" height="1" class="spaceRow"><img src="http://picsrv.fora.pl/Aeolus/images/spacer.gif" alt="" width="1" height="1" /></td> </tr> </table>
