Calculating The Stick

  1. Dec 5, 2005 #1
    I hope I've put this in the right forum, if not, please move it.

    I'm wanting to calculate the van der Waals bonding force/area of 1 cm^2 of "setae" carbon nanotubes that are 0.4nm(4 angstroms) in diameter. Such nanotubes are the smallest physically possible so that's what I want to go with. I want to use the Johnson–Kendall–Roberts adhesion theory to calculate the force/area, but I don't understand it. Would someone explain this math to me so that I may go about doing calculations? Thank you.

    Another problem is that these nanotubes don't have a hemisphere end, because carbon atoms aren't much smaller than this. The tubes do end in a dome-like cap, but it's only composed of a few atoms, so won't conform to simply making the ends of the tubes as perfect hemispheres in the calculations. What can I do?

    Hmmm, perhaps this was the wrong forum to post it in. Would one of the mods please move it to a better one? Thanks.:smile:
