(PhysOrg.com) -- Using highly uniform samples of carbon nanotubes—sorted by centrifuge for length—materials scientists at the National Institute of Standards and Technology have made some of the most precise measurements yet of the concentrations at which delicate mats of nanotubes become transparent, conducting sheets. Their recent experiments point up the importance of using relatively homogeneous—not overly short, but uniform in length— nanotubes for making high performance conducting films.
