Each conical needle in the array is a little oil collection device. The arrays can collect micron-sized oil droplets from water continuously and effectively,[url=http://www.myeduhelp.com/]christian louboutin booties[/url]," research leader Lei Jiang said.In tests the microscopic bed of nails could separate around 99 percent of mixed with water, the researchers said.Experts hailed the experimental findings."This excellent piece of work provides a perfect example of first describing an interesting biological system and then taking it one step further by solving an engineering problem,[url=http://www.govtvault.com/]cheap gucci belt[/url]," Joanna Aizenberg of Harvard University told the BBC. "It shows not only how we can learn from Nature but also how to apply that knowledge in bio-inspired design."</span></td> </tr> </table></td> </tr> <tr> <td colspan="2" height="1" class="spaceRow"><img src="http://picsrv.fora.pl/subSilver/images/spacer.gif" alt="" width="1" height="1" /></td> </tr> </table>
