The separation between neighbouring tubes is close to the separation between graphite layers. Typical diameters of MWCNTs are in the range of 5 - 50 nm. </div><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/6351866701211815078-1674724322299101537?l=nano-tubes.blogspot.com' alt='' /></div>Osváth Zoltánnoreply@blogger.com2tag:blogger.com,1999:blog-6351866701211815078.post-33107192813554939382006-08-23T09:53:00.000-07:002006-08-23T10:05:53.975-07:00<div align="justify"><a href="http://photos1.blogger.com/blogger2/3238/775374353175270/1600/fig1.1.jpg"><img style="FLOAT: left; MARGIN: 0px 10px 10px 0px; CURSOR: hand" height="206" alt="single wall carbon nanotube" src="http://photos1.blogger.com/blogger2/3238/775374353175270/320/fig1.1.jpg" width="299" border="0" /></a> A single wall carbon nanotube (SWCNT) can be thought of as a sheet of graphite (a hexagonal lattice of carbon) rolled into a cylinder. Typical diameters of SWCNTs are in the range of 0.7 - 1.4 nm and their length can be of several micrometers. </div><div align="justify">The image shows the different types of carbon structures: diamond, fullerene, graphite, and nanotube structure.<br /></div><span style="font-size:0;"></span><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/6351866701211815078-3310719281355493938?l=nano-tubes.blogspot.com' alt='' /></div>Osváth Zoltánnoreply@blogger.com2
