These nanowires give Damascus sabers another distinctive characteristic: a moir&eacute; pattern of banding on the steel.<\/div>\n<div>&nbsp;<\/div>\n<div>Apparently these swords were used against the Europeans during the crusades. I probably slept through this portion of history class by the way so I have no lucid comments to share with you on the battles.

Sure they didn&#8217;t know they had nanotubes in their hands but they did. There were no electron microscopes at the time; just tons of trial and error which as it turns out gave the armies who had these Damascus sabers a great advantage.<\/div>\n<div>&nbsp;<\/div>\n<div><a href=\"http:\/\/www.tmcnet.com\/usubmit\/2006\/11\/17\/2089257.htm\"><font color=\"#800080\">More<\/font><\/a><\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>I was stuck on an airplane yesterday and I don&#8217;t often read the New York Times.
